Editor's Comment

This year SAPEMA (Southern African Protective Equipment Marketing Association) celebrates its 50th anniversary. This means that for a half a century SAPEMA has been delivering its invaluable service to the industry - this is quite an achievement. We congratulate SAPEMA on this milestone and wish them success for the future years. We are compiling a history of the association to celebrate this occasion, I invite our readers to send me any anecdotes, photos, articles that you may have about the association over the years. These can be sent via email to [email protected], via fax to 011-886-1332 or via post to PO Box 72366 Parkview 2122. Also in this issue, we congratulate SAIOH on welcoming 3M as its first organisational member. See the story on page 25. We welcome Wihan Fourie, IoSM's recently appointed Secretary, see his first editorial on page 16. We thank Wilna Louw-Malan for all her contributions she made to National Safety over the years and wish her well with her future endeavours. This issue of National Safety contains a wide variety of articles. Read DuPont's cover story about a general sense of apathy towards safety policies regarding hazardous chemicals amongst local companies, operating in the manufacturing and engineering sectors. Steward Shapiro reports on the Eskom Medupi / Basil Read project, which is the construction of the coal ash dump and recovery holding dams - the infrastructure consists of various platforms, an access road network, an emergency platform, the liner system beneath the ash dump and three pollution control dams. An interesting read, we will report on it again when the project is well under-way. Lorraine Mashaba's article on hand arm vibration is written to create awareness on vibration hazards as many employees are exposed to this occupational health and safety hazard in their workplaces. Bill Pomfret continues with his series on PPE, in this issue focusing on eye and face protection. Hope Kiwekete's article offers some insight into risk appetite, a term that is not clearly defined in many risk management strategies, but clearly one that needs investigating.

COMPILED BY STEWARD SHAPIRO, A REGISTERED OCCUPATIONAL SAFETY PROFESSIONAL WITH THE INSTITUTE OF SAFETY MANAGEMENT WHO HAS BEEN INVOLVED IN THE CIVIL ENGINEERING FIELD SINCE 2004 AS THE HEALTH AND SAFETY ADVISOR FOR THE SOUTH AFRICAN FEDERATION OF CIVIL ENGINEERING CONTRACTORS (SAFCEC) AND WAS SUBSEQUENTLY APPOINTED BY BUSA TO REPRESENT THE INDUSTRY ON THE ADVISORY COUNCIL FOR OCCUPATIONAL HEALTH AND SAFETY (ACOHS). HE WAS ALSO APPOINTED TO SERVE ON THE CONSTRUCTION REGULATIONS TECHNICAL COMMITTEE RESPONSIBLE FOR THE AMENDMENTS TO THE CONSTRUCTION REGULATIONS OF JULY 2003. HE IS CURRENTLY WORKING FOR THE BASIL READ GROUP OF COMPANIES AS SHEQ MANAGER FOR ROADCRETE AFRICA (PTY) LTD AND IS WORKING TOWARDS OBTAINING ISO 9001:2008 AND OHSAS 18001 CERTIFICATION FOR ROADCRETE AFRICA.

Metallurgical coal is primarily supplied to Mittal steel mills, with certain semi-soft coking coal exported via the ports at Durban and Richards bay.

The environmental impacts of coal to the environment.

Coal is the dirtiest of all fuels - from mining to coal cleaning, from transportation to electricity generation and eventually to disposal. Coal releases numerous toxic pollutants into the air, water and land. These disrupt ecosystems and are endangering human health. Some can cause cancer and others may damage the nervous and immune systems as well as reproduction and development. The environmental impacts of coal use range from the poisoning of local rivers by acid mine drainage to global problems of climate change caused by carbon dioxide (CO2) emissions. Clean coal technologies are expensive and unable to completely remove harmful emissions from coal-fired plants. Some examples of coal's impacts on the environment are listed below: 1.Land Pollution Coal mining causes extensive degradation to natural ecosystems such as the forests and can scar the landscape irreparably. Damage to humans, animals and plants occurs due to habitat destruction and environmental contamination. 2.Water pollution Acid Mine Drainage (AMD) is created when exposed coal gets wet and

Overview of the project

The scope of work for this package entails the construction and the preparation of servitude prism, surface of ash conveyors which includes surface drainage, coal stockyard liner system, water containment, access and service roads, mess facility, construction of Mining Equipment Road over Conveyor Bridge, conveyor over Road Bridge, construction of ash dump, and recovery/holding dams, (enabling works for materials handling ­ ash) which includes: permanent access and service roads to ash dump area ( approximately 20 km), dump earthworks, initial-platform and wearing course for stacking (approximately 3,300,000 m3) which comprises the construction of the initial civil infrastructure required to support the beginning stages of the ash dump's development. The infrastructure consists of various platforms, an access road network, an emergency platform, the liner system beneath the ash dump and three pollution control dams. The project value is set to be ZAR 516 million. The starting date for the project was 2011/03/14 and the estimated completion date is 2012/10/19. A brief historical and environmental

background to the coal operation in the area and the environmental aspects that will be mitigated due to the construction of the works described above.

History of coal mining in Lephalae

Grootegeluk mine is situated in the Magisterial District of Lephalale in the Limpopo Province of South Africa. Exploration history in the Waterberg Coalfields dates from 1920, although larger scale exploration did not commence until the 1940s. Following intensive exploration by Iscor, beginning in 1973, a mining lease was granted in 1979 and 1980 - Grootegeluk Mine was established as the first and to date the only coal mine in the Waterberg area. Total mine production for Grootegeluk which includes discard coal since 1980 is some 561Mt rendering some 282Mt of saleable coal. Grootegeluk Mine is an open-pit mine operation. Processing is through five coal preparation plants, a sixth coal plant is under construction. Saleable coal products include semi-soft coking coal, metallurgical coal and thermal coal, with the latter predominating as a dedicated supply to the Matimba Power Station and soon Medupi Power Station.

dissolves toxic metals. The resulting runoff is noxious to aquatic life and renders water unfit for human consumption. AMD can contaminate drinking water sources and plague nearby communities for centuries or even longer. 3.Air Pollution The coal dust that is blown from trucks, rail and barges that are used to transport coal have negative environmental and health impacts on water and air quality. There is also the problem of air pollution from vehicles themselves. 4.Waste Pollution Mine waste is generated in huge quantities and needs to be disposed of. The waste is flammable and prone to spontaneous combustion. It also contains heavy metals capable of leaching into local rivers, streams and ground water. Coal washing generates similar waste problems.

the ZERO HARM policy on site and to ensure the project's success". Training has been identified as one of the vital tools during the project to ensure that all staff and workers, including subcontractors, are competent to perform their tasks in the safest manner possible. Various training workshops will be conducted during the course of the project and skills development within the local community will form part of the social responsibility of Basil Read. The health and safety component will form the cornerstone of skills development. Due to the magnitude of this project a number of sub-contractors will assist Basil Read during the construction phase. Apart from their CIDB rating as qualified contractors, stringent adjudication processes will still be conducted on all sub-contractors who will compete during the tendering process. Basil Read is committed to conducting business with its sub-contractors in a manner that reflects its principles and values. It is the company's view that by creating effective relationships Basil Read will succeed in establishing a sub-contracting / outsourcing chain that contributes to the overall performance of the project. Basil Read follows the Department of Trade and Industry's Codes of Good Practice on Black Economic Empowerment under Section 9(1) of the Broad Based Black Economic Empowerment Act. 2003 (Act No. 53 of 2003). Ongoing safety and quality assessments are conducted on appointed subcontractors to ensure a high compliance to requirements. No sub-contractor will be appointed or placed, before the "Permit to Work" requirement has been approved and signed off by the project manager, and counter signed by the relevant sub-contractor. Successful sub-contractors will ultimately work under the Basil Read SHEQ System that is certified to ISO 9001:2008, OHSAS 18001 and ISO 14001by the National Qualifying Authority (NQA). The total workforce including its subcontractors shall be identified as Basil Read for the duration and completion of the project and will have one objective "work and strive for the same result.... Zero Harm to all employees and the Environment". The following objectives and targets were set by the Basil Read Medupi SHEQ team: · Ensure ZERO injuries / incidents on site and on the project

· Ensure that all employees leave the site / project in the same healthy state as they arrived · Have positive attitudes towards safety, health and environment · Ensure the safety culture stays within the local community · Uphold the ZERO HARM policy on the site and project

Monitoring and Measurement

The following parameters are monitored: Environmental Parameters Significant environmental impacts: These include (but are not limited to): Noise: - Noise is monitored where levels could cause damage to employees' hearing. Dust: - Dust is monitored where the possibility of contracting silicosis exists. Waste: - The amount of waste produced, reused and recycled must be monitored and reported. Water quality: - Workshop/oil separation water to be monitored monthly, to ensure adherence to by laws. Fire readiness: - Fire extinguishers are monitored monthly, serviced annually, permitting of flammable liquid containers on site annually. Vehicles / Excavation equipment: Petrol/diesel tanks and oil sumps to be checked for leaks and perished or missing caps. Oil sampling: - Oil samples are monitored during plant services. The results of environmental monitoring and measurement are analysed monthly, to determine where deviations or poor performance occurs.

SHEQ requirements of Basil Read and Eskom

Safety is the number one priority on the Eskom Medupi Project and for Basil Read. Client and contractor have just started this journey which is of national importance to the country as a whole. The objective at the Basil Read Medupi Project is to adopt a ZERO HARM policy to ensure the success of this project. Occupational Health and Safety form an integrated part of the Basil Read way of business. It is not just based on, and I quote George DESOUSA, Project Manager of Basil Read "Legal Compliance and Corporate Social Responsibility, but also a Moral obligation which is one of the core values we at Basil Read strive for. Risk will always be part of a project, especially of this magnitude but risk can be minimised, mitigated or eliminated by adopting the right attitude towards safety, health, work, and fellow workers and through our civil engineering experience." The Safety Manager, Leonard Jooste commented: "numerous risks will manifest themselves during the project but the risk that stands out the most from a safety point of view is the use of plant and machinery on this project. Over the past few years numerous accidents / incidents were caused by plant / machinery and operator error. The commitment from Basil Read Medupi management and staff will be vital to ensure that Basil Read upholds

Occupational Health and Safety Parameters

Performance of the occupational health and safety management system is assessed using monitoring and measurement parameters. These parameters must be both proactive and reactive, and always aligned with the company objectives and targets, as well as current legislation and other requirements. Proactive measures of the OH&S system include (but are not limited to): · Employee Health (with due exposure limits): Employee hearing, eye sight and lung function are monitored during entry

medical assessments, using a professional occupational health clinic. · Suitability, condition and availability of PPE: Monitored on a weekly basis by the appointed person in each area and working teams. All deviations must be noted and corrected. · Condition of equipment in use: All equipment must be inspected before work can proceed. All deviations must be reported immediately. Reactive measures of the OH&S system include (but are not limited to): · Accidents/incidents: Investigations into accidents and incidents involving employees and subcontractors working on behalf of Basil Read. Statistics on safety and health are reported on during SHEQ meetings and forwarded to BR Head Office on a monthly basis. · Property Damage: Investigations into property damage to determine the root causes. · Employee health: An entry medical assessment has been conducted on all employees of the project to establish a baseline report on their health. It is also mandatory that an exit medical assessment should be conducted after the completion of the project. Sick or injured employees are given medical treatment to determine the extent of their illness or injury and/or any improvement or deterioration of the condition. The results of safety and health monitoring and measurement are analysed monthly, to determine where deviations or poor performance occurs.

The DEO will be the environmental link between Basil Read and the client's representative and will report daily to RE on environmental matters. Any deviation from the EMP or EA will result in an immediate shut down of activities. The EMP also allows that complaints from interested and effected parties be registered and addressed accordingly. Reports must be submitted to the client's representative. ISO 9001:2008 is but one of the quality objectives for the project ­ we will continue to look for areas of improvement through comprehensive audits (internal, external, customer, and supplier) we continually strive to identify areas where improvement is deemed necessary. 1.

Cover Story

SA COMPANIES NEED TO IMPROVE SAFETY POLICIES FOR WORKERS EXPOSED TO HAZARDOUS CHEMICALS

According to latest statistics by DuPont, the global leader of market-driven science, 35% of South African companies, whose employees are regularly exposed to chemicals, have a view that their current safety policies are adequate, resistant to reviewing and introducing more progressive measures to protect their employees. Lizette Kasselman, sales specialist at DuPont says that the survey illustrates a general sense of apathy amongst local companies operating in the manufacturing and engineering sectors. "As levels of production increase locally, workers are more exposed to new types of chemicals, each with varying hazard levels. It is crucial that companies' safety standards and protective apparel evolve concurrently, as these sectors grow." charges as well as medical and insurance costs, which could lead to substantial reputational issues."

ADHERENCE TO HEALTH AND SAFETY REGULATIONS

Kasselman says that local manufacturing and engineering companies also need to continually adhere to health and safety regulations, by providing employees with equipment that meets or exceeds the base requirements necessary to safeguard against the materials they are routinely exposed to. "For example, CE marked products are a manufacturer's declaration that a product complies with the relevant European health, safety and environmental protection legislations ­ this is recognised locally as the required protection standard for hazardous environments."

IMPORTANCE OF UNDERSTANDING PTOTECTIVE APPAREL RISK

Kasselman adds that understanding the protective apparel risk categories is important when identifying which equipment to use for specific environments. "The design and production of the appropriate types of protective apparel is measured against a three-tiered risk categorical system, from low to high risk exposure environments. As the risk exposure increases, each category stipulates more stringent certified production requirements and quality controls." She explains that Category 1 apparel should be used for lowrisk environments, as these are self-certified by the manufacturer, i.e. sun glasses or poor weather clothing. Category 3 chemical protection apparel, on the other hand, should be supplied for exposure to high-risk environments, as these have gone through stringent chemical permeation testing processes and have been audited by a quality assurance body. She explains that improved safety standards have myriad benefits for both employee and employer. "If unprotected employees are exposed to hazardous chemicals there could be considerable consequences for both the firm and the individual. The individual may experience permanent life-long damage and the company could face potential litigation

SUPPLIERS MUST ADHERE TO THE HIGHEST SAFETY STANDARDS

Kasselman says that companies should choose suppliers that adhere to the highest safety standards governing the industry. "One way to do that is to request a copy of the supplier's safety policies. Companies should also ensure that all protective apparel contains a manufacturers' declaration, stipulating that the product complies with the essential requirements relevant to health, safety and environmental protection legislations." DuPont's recent joint venture of US-based MECS, a leading global provider of process technology, proprietary specialty equipment and technical services for sulfuric acid producers, illustrates the growing trend of collaboration and inclusive innovation between technological companies and their industrial and chemical customer base, in order to improve operational efficiencies and safety. "Continuous evaluation and improvement of existing safety standards are required to ensure South African companies remain competitive globally, by complying with international benchmarks and best practice," concludes Kasselman.

Hand arm vibration in workplaces

LORRAINE MASHABA HOLDS A BACHELOR OF ARTS DEGREE FROM THE UNIVERSITY OF LIMPOPO, MAJORING IN PSYCHOLOGY AND ANTHROPOLOGY. SHE CURRENTLY WORKS AS THE HEAD OF OPERATIONS AND MARKETING AS WELL AS AN OCCUPATIONAL HEALTH AND SAFETY CONSULTANT FOR SENINHLE OCCUPATIONAL HEALTH SERVICES CC.

Many employees are exposed to the occupational health and safety hazards of hand arm vibration in their workplaces. According to the Occupational Health and Safety Act, Act No. 85 of 1993, section 8, all employers should provide and maintain a safe working environment for their employees. The article is written to create awareness on hand arm vibration hazards. It will focus of the following: · Hand arm vibration described · Health effects related to hand arm vibration e.g. Hand arm Vibration Syndrome (HAVS) · Symptoms of hand arm vibration syndrome · Activities and processes where employees may be at risk of HAVS · Risk control

Hand arm vibration described

Hand arm vibration may be described as the transfer of vibration from vibrating equipment to the hands of an employee. Many employees who are exposed to hand arm vibration may not be aware of the risk associated with it. It is vital for employees to have sufficient information on the kind of job they perform, the hazards related to it and the protective measures.

machinery) for longer periods such as 8 hours or more, may experience hand arm vibration syndrome (HAVS). The Occupational Health Clinics for Ontario Workers Inc. describe hand arm vibration syndrome as a disease that involves circulatory disturbances, sensory and motor disturbances, and musculoskeletal disturbances. As already mentioned, employees who use vibrating instruments for longer periods may suffer from this disease. Vibration may cause blood vessel damage which may result in various diseases, e.g. Vibration White Finger (VWF). Other forms of damage can affect the nerves and muscles of the fingers and hands. This damage may cause numbness and tingling, loss of

feeling and reduced grip strength. According to the HSE Information Sheet MISC493 "people who have the hand arm vibration syndrome are at risk of

developing Carpal Tunnel Syndrome (CTS). Carpal tunnel syndrome is a pain and stiffness in the wrist, elbows etc" and is illustrated in figure 1. We all use our hands and arms to execute duties assigned to us; as a result, employers need to ensure that employees are safe and not at risk of being injured.

Symptoms of hand arm vibration syndrome

Tingling sensation or "pins and needles" are the early symptoms of hand arm vibration syndrome. Symptoms might advance in a sense that the person might suffer periodic attacks in which the fingers turn white when exposed to cold. The extent of this whitening, commonly known as finger blanching, depends on the severity of the condition. The HSE Information Sheet MISC493 states that periodic attacks last up to half an hour or longer and often end with painful, throbbing return of blood as the colour of the fingers change to bright red. In very severe cases, blood circulation may be permanently impaired and fingers may take on a blue-black appearance.

measuring the extent to which employees are exposed to vibration. They may also advise on the correct Personal Protective Equipment (PPE) that may potentially reduce the transfer of vibration from the equipment used to the hands of an employee. Employers should try to prevent or limit exposure of employees to vibrating equipment and tools.

Activities and processes where employees may be at risk of HAVS

The biggest question we ask ourselves is: who is at risk of developing hand arm vibration syndrome? The type of job you perform and the industry you work in will determine if you are at risk of developing hand arm vibration syndrome. If you spend most of your shift working with vibrating instruments such as power drills etc. then you are at risk. Employees who are working in construction, mines, etc. are also at risk of developing hand arm vibration syndrome and other health effects related to vibration.

Risk control

Now that we all know our risks, it is important that we find out how to control the risks we are exposed to. It is important that employees be trained on how to notice early signs of hand arm vibration syndrome so that they can be treated before it advances. Some Approved Inspection Authorities (Occupational Hygiene consulting companies) and vibration specialists may be of great help in assessing and

Is a risk appetite statement the answer?

Risk management provides the opportunity assess our business risks. Once these have been taken into consideration, then comes the reality of which of those risks are we prepared or not prepared to accept. The "one-size-fits all" approach does not apply. The environment in which businesses operate is complex so are the risks. That is why you find that many organisations are

Introduction

There is no doubt that when a chief executive fails to realise profits for the shareholders of any organisation his/her tenure may be short lived! However, whilst the quest may be on profit maximisation, the question would be what levels of risk is the executive prepared to allow or even put up with? Does the environment in which an organisation operates in determine its risk appetite? Certainly it will. As organisations move towards embracing risk management, they still have a daunting task to instil an appetite for risk. This article offers some insight into two critical words "risk appetite".

Why risk appetite?

Often times risk appetite is not clearly defined in many risk management strategies. The International Organisation for Standardisations' (ISO) 31000:2009 Risk management - Principles and guidelines is case in point. Nevertheless, the ISO Guide 73:2009 defines risk appetite as "the organisation's "approach to assess and eventually pursue, retain, take or turn away from risk". What we take from this definition is that an organisation needs to put up a strong statement on how it considers what will constitute its risk appetite. Some risk practitioners might even say it's easier said than done. The Institute of Internal Auditors gives some clarity on this broader example that "a company that says that it is does not accept risks that could result in a significant loss of its

putting across their risk appetite results in form of both quantitative and qualitative metrical methods. But before all this happens, as outlined in figure 1, Dr Helen Lange MBA Program Director and Associate Professor of Finance at Universitas 21 Global asks on where do we find risk? If we have the answers for this, then one is able to come to an agreement on those risks that are acceptable. This will then provide a threshold of those risks that an organisation is willing to take. According to KPMG (2008) the following characteristics constitute "a well-defined risk appetite" These are; "Reflective of strategy, including organisation objectives, business plans and stakeholder expectations, reflective of all key aspects of the business, acknowledges a willingness and capacity to take on risk, is documented as a formal risk appetite, considers the skills, resources and technology required to manage and monitor risk exposures in the context of risk appetite, is inclusive of a tolerance for loss or negative events that can be reasonably quantified, is periodically reviewed and reconsidered with reference to evolving industry and market conditions, has been approved by the board"

tolerate. It is critical for all levels within the organisation to be aware of the risks faced in respective business units as well as in the entire organisation. Richard Barfield from PricewaterhouseCoopers affirms that "to embed risk appetite effectively in the business requires management to establish limits for each risk type and cascade them to lower levels in the organisation".

Where do we go from here?

There is still hope for those organisations that have not yet decided on their risk appetite. For those that are prepared to kick start the process, they need to first understand and define their risk appetite. Laying the foundation for a risk appetite framework among others entails that, senior leadership should ensure it's entrenched into the day-to-day business operations. The reality is that for anyone running a business, risks will always be there. Even though we hardly hear of organisations benchmarking on how they have reached risk appetite thresholds, the bell still rings that organisations should not forget their risk appetite. The bottom line is that the quest for profits without taking this into consideration will wreck your business strategy.

Role of senior management and the board

The reality in any business is that if risk management is isolated from the rest of the business it's bound to yield no results. Senior leadership or the board have a role to play to ensure that this negative outcome does not happen. The risk faced by many organisations is whether their senior leadership is in a position to guide them on what risks they should

The Importance of Quality Risk Management Processes

by Marina Sander ­ IRCA Global Operational Executive: Education and Training Risk management principles are effectively utilized in many areas of business and government including finance, insurance, occupational safety, public health and by agencies regulating these industries. Although there are some examples of the use of quality risk management they are limited and do not represent the full contributions that risk management has to offer. In addition, the importance of quality systems has been recognized in industries, and it is becoming evident that quality risk management is a valuable component of an effective quality system. It is commonly understood that risk is defined as the combination of the probability of occurrence of harm and the severity of that harm. However, achieving a shared understanding of the application of risk management among diverse stakeholders is difficult because each stakeholder might perceive different potential harms, place a different probability on each harm occurring and attribute different severities to each harm. In past years, risk management was mainly applied in the context of safety at work, environmental safety, product safety and product liability (and related insurances). The Risk Management Process courses focus on the safety of people, the environment, technical systems and processes. In these individual subfields, risk evaluation and risk treatment is performed in a bottom-up approach. The bottom up approach helps all employees to identify hazards and to report them to their line managers. More recently, risk management has gained new importance as an obligation of the top management and executives within the framework of corporate governance. The primary task of risk management is to contribute to the achievement of strategic, operational and financial objectives as well as objectives related to the safety of people and the environment. A top-down approach is used for risk evaluation and risk treatment. An effective risk management process means that all risks are being controlled and that no problems will occur. In order to control these risks, it is necessary to do the following: a) identify and understand the risks b) try to foresee any possible consequences c) predict who is going to be involved or affected and d) implement successful safety measures that will minimise or even eliminate the risks. In other words there is a need to assess any possible risk involved in each activity (risk assessment); decide how to approach the problem (risk strategy), and employ all measures needed for the participants' protection (safety measures). The IRCA Global Risk Management Process courses aim to cover the combination and coordination of the top-down approach and the bottom-up approach - thereby, risk management becomes a powerful tool for managing organisations in order to cope with increasing complexity.

IRCA Global Risk Management Process courses based on ISO Risk Management Guidelines:

Risk Management Process and Management Systems

Many organisations do not have a comprehensive management system. Either they only have parts of a management system or they are managed on the basis of more or less systematic interpersonal direction and control. In such a context, risk management can be designed independently if it is justified by the size, complexity and risk exposure of the organisation. The risk management process can however be interpreted as a management responsibility and be integrated with other Management Systems, where in place ­ the example shows integration with the ISO 9001 Process Model

Outcomes of the Risk Management Process:

As a result of successful implementation of the Risk Management process: 1.A risk management strategy is established and used that includes plans covering mitigation and contingency measures, methods, criteria, (including criteria for acceptance of residual risk after risk mitigation actions) and parameters for management of risk. 2.Risks are identified and assessed for their risk attributes, such as likelihood and consequence. 3.Risk mitigation is performed when analysis indicates action. 4.Risk mitigation actions and risk status are monitored to determine their effectiveness and corrective action is taken as needed.

MSA Africa turns heads with branding

MSA Africa, the leading manufacturer of sophisticated safety equipment, has introduced a new service. Logo Express, a division of MSA Africa, is a new in-house design team that offers branding opportunities for customers looking to showcase its commitment to the use of high-quality safety equipment. It allows for faster production time with higher quality graphics at lower costs. Delivery time will be reduced from 36 days to 12, from artwork sign off to the time the order reaches MSA's finished goods stores. For a minimal fee, customers can have their logos, or other text, printed on a MSA V-Gard® cap or hat. The logo can be placed in four different positions (left, right, front and back) with a choice of up to ten different colours per job (minimum order is 50 units). Logo Express also uses both single and multi-colour embedding techniques. The embossing process has been carefully developed to ensure that the artwork does not harm the composition of the hardhat in any way, unlike stickers or paints that are normally used. The Logo Express design specialists can assist the customer with new designs and type, but also offer a range of standard logos to choose from. Logo Express' simulator tool enables customers to view the completed hardhat before manufacturing. The branding of hardhats can assist with increasing professional brand exposure and the feel of ownership (thus decreasing wear-and-tear).Branded hardhats can be used in company celebrations, safety campaigns, promotional activities, or for the simple day-to-day identification purposes.

As President of IoSM I am confident that we have the correct people in the correct positions to achieve our goals. I mentioned in last month's letter that great things are waiting for us. This is just the start. Watch this space!! Congratulations to Wihan Fourie who has been appointed as National Executive secretary. Welcome to this role Wihan, we are looking forward to your valuable contribution.

From the Secretary's desk

You might remember an e-mail notice being sent to all members of IoSM on the 6th of April this year which came from office of the President of IoSM. It carried the sad news that Wilna Louw-Malan had resigned from being the National Executive Secretary. Allow me this opportunity to thank Wilna for her dedicated hard work and commitment to the growth of IoSM. I also wish her good luck with her new venture out of the occupational Health Wihan Fourie and safety circle. After consideration was given to all applications to the advertisement for National Executive Secretary, I was appointed into the position. By accepting this responsibility, I hereby confirm that I will commit myself to do my utmost best to promote and grow IoSM as far as is reasonably possible. The administration and national office will continue in the good hands of Amanda Louw. The office is in the process of relocation, but rest assured that no information or contact will be lost in the process. Amanda will still be the voice on the other side of the phone and continue to handle all IoSM matters with the speed and accuracy as she has done in the past. That being said, what is new in IoSM? On the 5th of May, as you are all aware, IoSM had a professionally facilitated Strategic Planning session. Why you may ask. What brought this about? Well, this session was planned due to a lot of requests from our members. Sad to say, a lot of members brought concerns to the table to initiate an action like this, however, only about 30 members out of 700 attended the planning session. The purpose of this session was to achieve the following: · Business definition - Vision - Mission - Strategic goals and objectives framework - Core business values - Outcomes - Stakeholder framework · SWOT Analysis - External environmental analysis - Internal environmental analysis · Target Perspective - Strategic goals and objectives - Performance indicators linked to objectives

Toolbox topic for May - ARC WELDING SAFETY

Safe and accident free completion of any welding operation should be the goal of all welders. Here are a few welding safety tips that will help you achieve that goal. Wearing proper eye protection is very important. Welders and their helpers should be sure to use the correct filter lens in their goggles or helmets to protect their eyes from infrared and ultraviolet light. Precautions for fire prevention must be taken in areas where welding is being done, for example, isolating the welding and cutting area and removing fire hazards from the vicinity. If normal fire prevention precautions are not sufficient, a qualified person should be assigned to guard against fire during the operation and for a suitable time after completion of the work, to ensure that no possibility of fire exists. Be sure that fire extinguishing equipment is available and ready for immediate use. In areas where heavy dust concentrations exist, or where flammable paints or other flammable materials are present, welding, cutting or heating can create a significant fire hazard. Proceed with extreme caution! A noncombustible or flameproof screen should isolate the welding or cutting area to protect other workers in the vicinity from direct arc rays. Watch your slag; it could cause a serious injury to someone working below OR CLOSE. If the electrode holder is left unattended, the electrodes must be removed, and the holder must be placed so that electrical contact cannot be made with another employee or any conducting object.

Labour inspectors leave no stone unturned

"The last 12 months saw heightened activity among the Department of Labour's inspectors as they criss-crossed the country to ensure compliance with all pieces of legislation", Labour Minister, Nelisiwe Oliphant, said in her first Budget Vote Speech to Parliament. She explained that the process bore fruit with 72 percent of workplaces found to be complying with the law. She continued that notices have been issued to recalcitrant employers, with 283 cases having been referred to the Labour Court while a further 328 were sent to Magistrates. Courts. "We hope that those who flout the laws will be successfully prosecuted", she said. Oliphant said the blits inspections had targeted `high-risk and problematic.. sectors such as wholesale and retail, agriculture and forestry, hospitality, private security and several shopping malls. She told Parliament that 15 833 inspections were conducted, thereby exceeding the Department's target of 7 250.

Safe work practices for workers in hot environments

Some jobs must unavoidably take place in hot working environments. Working in conditions of extreme heat combined with additional stresses to the body from physical activity, loss of fluids, fatigue, and various other factors, can lead to dangerous health effects or can jeopardize worker safety. However, if the risks are understood and precautions are taken, work in hot environments can be performed in relative comfort and security. Monitoring - Supervisors should check environmental conditions at least hourly and monitor worker response to the heated conditions. Heat stress is a silent hazard. Workers my not realize that there is a problem until heat stress is well advanced. Educating - Workers should be aware of the need to replace fluids, recognize dehydration and heat exhaustion, and know what to do when those conditions appear. Employers should train workers to recognize early warning signs of heat distress and take prompt, appropriate action.

For those of you who could not make it to the Wits Branch meeting on the 17th May, 2011, you missed an awesome presentation by Leighton Bennet on Property Loss Insurance! The good news is that this was part one and part two will be presented at a later date. A synopsis of Leighton's presentation follows:

"Understanding Property Loss Insurance"

By Leighton Bennett, SHE & Risk Management Consultant. Benrisk Consulting (BSC, MDP dip, ROSProf, Fellow Institute of Safety Management, Associate Institute of Risk Management SA). All business and the individual suffers different levels and types of property loss at some time, but few people know or understand how the short term insurance market estimates and assesses these property losses. Leighton will explain how and what is considered to calculate property loss estimates. Leighton is known in the insurance industry as a free-lance "insurance surveyor" who surveys sites & writes the technical insurance underwriting reports that give the various loss estimates (both material/property damage & consequential/business interruption losses) needed by insurance brokers, for the broker to place the necessary risk financing insurance cover with insurers. When a property loss event occurs the "loss adjuster" performs the post incident loss estimates.

By Tinus Boshoff Driven Machinery Regulations: The 'Driven Machinery Regulations' were published on 4 March 2011(published under GNR.163 in Government Gazette 34052). The above mentioned publication was supposed to be published for public comment first (draft regulations) and not as the actual new regulations. This was corrected through Government Correction Notice According to the draft regulations, it repeals GNR 1010 of 2003. It is assumed that this refers to the 'Driven Machinery Regulations' of the OHS Act. The reference however is incorrect; GNR 1010 of 2003 refers to the previous amendments to the Driven Machinery Regulations. The Driven Machinery Regulations were in fact promulgated under GNR 295 of 26 February 1988. The draft regulations now states that these regulations shall apply to the design, manufacture, operation, repair, modification, maintenance, inspection and testing of driven machinery. Some of the proposed changes include: Definitions: 'Calendar'; 'Capstan Hoist'; 'Block and Tackle';

Reactivation meeting of the South African Asbestos Forum

Contractor, to ensure standardisation of asbestos contractor applications, to ensure legal compliance to relevant legislation by Asbestos Contractors and to provide a basis for verification. An application for registration by an Asbestos Contractor should include amongst others information on the following matters; company details, relevant education and training, equipment, medical surveillance and disposal methods. Several members of the Asbestos Forum gathered for a meeting at the Department of Labour on 17 May 2011 which took place at Leboria House, Pretoria. The meeting was called by the Department of Labour to discuss the Criteria for Registration as an Asbestos Contractor and to finalise the name of the Forum. Hendry Russell from Environmental Asbestos Removers, Greg Murry from Focus Asbestos Removals, Garth Hunter from ENGEN, Attie Greyling from NOIH, Koos Roets from COH and Hugo Kotze from Industech were joined by Milly Ruiters and Elize Lourens form the Health and Hygiene Unit of the Department of Labour. The meeting members discussed the requirements for applications to the Department of Labour by Contractors wishing to registrar as Asbestos Contractors as specified in the Asbestos regulations GNR 155 of 2002. The purpose of the criteria is to provide clear requirements for any company whishing to register as an Asbestos Input by the Forum members will be incorporated into the document before it is circulated for comment to current registered Asbestos Contractors and other role players. The meeting also finalised the matter of the official name of the Forum. It was decided that in future it shall be referred to as the South African Asbestos Forum. Several further activities are planned by the Forum such as reviewing the Asbestos Regulations in collaboration with Technical Committee 7, launching a website and setting standards for asbestos awareness training.

Mpumalanga Branch

Occupational Hygiene professionals from all over Mpumalanga, Gauteng and even the North West and Limpopo province attended a workshop on 27 May 2011 in Middelburg hosted by the SAIOH Mpumalanga Branch. It was a well organised event with an interesting and comprehensive programme. In fact, an event which will be remembered for its knowledgeable speakers and very informative presentations.

The function started with a warm welcome from the Chairperson, Hannes Botha after registration and coffee, while the delegates tried to curb the cold that is so typical of a Middelburg winters morning. The workshop was kick started with an informative presentation by Jaco van Rensburg (Gijima OHES) on a much perplexed topic, namely PAHs and CTPVs. Discussion on this topic continued in Willem Wepener's (Biograde Laboratory) presentation where he focused on PAH/CTPV and SiO2 (Crystalline Silica) analytical methodologies and the requirements for an Analytical Laboratory to present high quality sampling results.

Before lunch was served the 44 delegates took part in two useful sessions, namely an informative presentation by Jaco on SiO2 and the SAIOH Mpumalanga Branch AGM. During the AGM feedback was given on several SAIOH matters by Hannes Botha (Chairperson), Melinda Venter (SAIOH President) and Deon Jansen van Vuuren (SAIOH Council and OHPC member). with participation from the group filled with curious minds. The function was also used to nominate and appoint new branch committee members, as a few of the current committee members served their terms and had to step down. The branch extended its appreciation to Hannes Botha (Chairperson), Liezel Strydom (Treasurer) and Jacques Wasserman (Secretary) who had served on the committee with extreme passion and vision. Best of luck for Bohlokoa Matshiane (Acting Chairperson) and the newly elected committee members!! We know that you will all do the name of the branch proud and may God bless all your endeavours.

A short coffee break followed giving participants the opportunity to enjoy the winter sun and the splendour of the Pienaardam Ontspanningsoord natural surroundings.

The workshop ended on a high note with an educational session chaired by Jaco van Rensburg. Delegates were given the opportunity to ask any Occupational Hygiene related question, with answers and guidelines given by qualified Occupational Hygienists and supported

A basis for process pressure relief

ROB HAS WORKED

ON OIL DRILLING PROJECTS IN GABON, SAUDI ARABIA, QATAR, THE UNITED ARAB EMIRATES, OMAN AND THE UK FOR SOME YEARS.

Causes for overpressure

A listing of the causes of creating an overpressure in a system or item of equipment, can be endless. Some of the more obvious ones have thus been omitted from the following list: 1. Ambient conditions, such as direct sunshine or simply the day warming up, has a serious pressure increase effect on especially those fluids with high coefficients of expansion, such as LPG. Where pockets of such fluids are trapped between closed tight shutoff valves, the pressure increase can be enormous. The reverse is also true, where a volume of gas is trapped between tight shutoff valves when it is hot and the temperature drops. This can create a high vacuum in extreme cases. Vacuum relief may be needed if the system is not designed for it. 2. Heat exchangers, with the cold side shut in but the hot side still flowing. The cold side thus heats up and expands but has nowhere to go. This is similar to the ambient effects. 3. A power failure that trips cooling fans, pumps or compressors. Power failures may affect the entire plant or be only localised. It should be noted that localised (single sub-station) power failures often create larger relief loads than total power failures. 4. Cooling failures. This can be the failure of a cooling water pump, a column reflux pump or even a boiler feed water pump, if used for preheating across a heat exchanger. 5. Valve failure, either open or closed. An outlet valve failing closed will prevent the fluids from being discharged and affect the upstream process. An inlet valve failing open will affect the downstream process. In a system that relieves liquids from a high pressure drum in 2-phase service (gas and liquid) to a lower pressure drum under level control, the fail open of the level control valve, or by-pass opened inadvertently, may result in the upstream vessel emptying of liquid resulting in a gas blowby. Since a much greater volume of gas can pass

through a control valve (or manual valve) than the liquid for which the valve is sized, such a situation is highly likely to create a sudden and huge increase in pressure in the downstream drum and require a large relieving volume. 6. Failure of automatic controls instrumentation. This is a separate subject altogether and one that keeps safety engineers very busy. The results are similar to (5) but the pressure relieving provisions may include extra integrity of the safety instrumentation system. 7. Blocked outlets. Outlets could become plugged with solids or high viscosity material, such as wax or hydrates, or there could be ice build up across a Joule-Thomson effect valve. 8. Reverse flow - failure of check valves to work. This can occur when a feed pump or compressor to a gas/liquid system stops and the higher pressure discharge system reverse flows back into the lower pressure system. Dissimilar double non-return valves in series are used to reduce this effect. The scenario then calls for the total failure of one NRV and the other passing 10% of its rated maximum. With a single NRV, full backflow must be taken into consideration. This effect can also be experienced on standby pumps in especially hot service, where the standby pump has a constant small stream of liquid passing backwards through it from the discharge of the running pump. Check valves in such systems often have small holes drilled to enable such warming flows to take place. Where the suction system is of a lower piping specification than the discharge system, shutting the suction valve of the standby pump but having an open or leaking discharge valve, would result in the suction system experiencing full discharge pressure. This may need pressure relief provisions to be installed, especially where the pressure differences are high (at some offshore oil installations the difference can be up to 100 bar, with multi-stage pumps).

This article is aimed at providing the safety professional with some insight into the ramifications of providing pressure relief in process systems. Most industries have at least one process that requires pressure relief provisions in terms of legislation or international standards. Sadly to say, it is the author's experience that in many cases the finer points of pressure relief are not fully understood by those who design these systems, with the result that the systems are either inadequately protected, overprotected or incorrectly installed and/or operated. The relevant regulations or standards call for pressure relief on a particular item of equipment. OK, but what should it be based on? The following questions need to be answered and the findings acted on in order to ensure that (a) the correct pressure protection device is installed, (b) each specific item is sized correctly, and, (c) the relief outlet system is sized correctly: · What will be the cause(s) for creating an excess pressure? · Will the increase in pressure be sudden or gradual? · Will the increased pressure be transient or lasting? · Will the influence creating the pressure rise be from within the process or outside of it? · How much material is needed to be relieved to maintain the pressure within the maximum allowable working pressure (MAWP)? What will be the loading of the (eg) flare system? · What is the nature of the material being discharged?

9. Changes in process conditions. Another oil production example is the retrofitting of gaslift to production wells. The gaslift system may be at a far greater pressure than the production risers and manifolds were originally designed for. 10. Operation mode. Process systems are constructed, pressure tested, commissioned, started up, shut down, cleaned out, etc. At each stage of these operations there may be opportunities for the pressure conditions to exceed the design conditions. For instances, steaming out a distillation column to rid it of hydrocarbon vapours, may create a vacuum in the column if the outlet is shut and the column allowed to cool. Also, the steam pressure may be at a far higher pressure than the MAWP and the column may be subjected to full steam pressure. Same with an air blow cleaning activity during commissioning. Many such operations take place with the safety relief valves blanked off or removed. 11. External fire. A heat input rate of up to 108,8 kW/m2 of exposed surface can be experienced by closed systems involved in a fire. Vessels containing flashing liquid will rapidly overpressure. The external fire case is the most common one to base PRV sizing on. Beware of multiple items of equipment all involved in the same fire and all relieving at the same time into the same closed system (eg flare). The flare line must be sized accordingly to ensure that backpressure does not increase to unacceptable levels.

consideration. Backpressure should not exceed the set pressure by 10% for fire cases and 21% for any other case. These valves are only to be used where the superimposed backpressure does not vary significantly. The most frequent application for this type of valve is as follows: i. for discharge to atmosphere through short tailpipes. Note: Tailpipes should NOT be chamfered. Although chamfering reduces the noise level of atmospheric discharge (larger exit area) it also creates excessive horizontal reaction forces on the tailpipe that leads to higher forces and moments on the valve body. This requires complicated supports to address these additional stresses. ii. Where high set pressures are used. iii. Where the PRV discharges to a low pressure manifold system. b. Balanced Type. These are little affected by constant or superimposed backpressure. The following types are available: i. Piston type, where the guide is vented such that backpressure on opposing faces of the disc cancels itself. The top face of the piston has the same area as the nozzle seat, and the bonnet is vented to atmosphere. ii. Bellows type. The effective bellows area is the same as the nozzle seat area, and by attachment to the valve body, excludes backpressure from acting on the top side of the disc. iii. Bellows with auxiliary balancing piston type. A combination of the above two. c. Pilot operated type. A differential piston is loaded by the process pressure through an orifice. If the set pressure is reached, the small spring loaded pilot valve opens, venting pressure above the piston of the main valve, which then rapidly opens wide. Modulating type pilots have valve openings that are proportional to the overpressure. When process pressure is restored to below set point, the main valve closes rapidly. The application for this type is as follows: i. Where it is desirable to operate the process pressure close to the MAWP (and PRV set pressure). This is not possible with conventional PRV's or rupture discs. ii. Only use in clean vapour service. If they must be used in a fouling service, suitable precautions must be taken to avoid plugging.

iii. Not to be used where the pilot line can plug or freeze. iv. Select this device to be compatible with temperatures that can be expected when relieved fluids flows across the orifice (Joule-Thomson effect). v. Not to be used in service exceeding 2000C due to elastomers used in the pilot valve and/or the main valve seat. d. Pilot assisted type. In this type the PRV is still capable of operating as a normal conventional valve in the event of pilot or actuator failure. This type is preferable to the pilot operated type. If accuracy of setting is important, or rapid opening and closing are required, this type of PRV should be considered. e. Rupture discs. This subject is covered in some detail in a previous article in National Safety. f. Buckling pins, or, rupture pin relief valves. These are non-reclosing devices, similar to rupture discs, but, they can be reset (replaced) externally without the need to open flanges. A rupture pin valve has a piston held in the closed position with a buckling pin designed to bend at a set pressure. Experience with this type of device has not been good. If considering this type of pressure relief device it is advisable to obtain an independent (not the manufacturer or supplier) failure modes and effects analysis, or, a fault tree analysis, to verify the reliability of the device. Pipe support, pipe stress and pipe alignment all become quite critical around rupture pin type valves.

Relief device types

There are a number of different types of pressure relief devices. Each one has its specific applications and there is no "one for all seasons" type of device. Selection of pressure relief devices is unique to each individual application. However, some general guidelines will assist the safety professional in determining whether or not there may be a problem. 1. Pressure relief valves a. Conventional type. These are nozzle entry type and have enclosed springs for flammable, toxic or hot condensate service. Valves in air, cooling water or steam service, can be open bonnet type. The disc has a greater area than the nozzle seat, thus backpressure on the disc (the outlet side) must be taken into

Locking out is OHSAct GMR & EMR requirement and no lockout is possible without the necessary lockout equipment. Each padlock provided must have its own unique key. The wrong equipment isolated or any piece of equipment, etc not identified and isolated could cause a serious/ fatal injury, eg. electrical shock, electrical burns, electrocution, panel explode through short circuit, etc The notification should reduce the possibility of someone trying to start/ re-energise any equipment being worked on. Energy sources include: electrical, mechanical motion (kinetic), thermal, potential (pneumatic, hydraulic, static, stored), chemical reaction energy and gravity. Know where to find the isolation devices locations and how to isolate the different energy source types OHSAct requires positive physical padlock type lockout, than to just tagout. A calliper allows others to also lockout such that the equipment can only be re-energised until all locks on a calliper are removed. An unclosed pad lock is not a positive lockout. To clear all people away from any equipment, etc before you attempt to start the isolated equipment or use a test instrument to test to prove zero energy present, ie. lockout is effective. Any person could energise a machine while a lockout has been removed, which could cause an injury or equipment damage while certain safeguards are removed while under repair. Maintenance, etc.

KNOW (What knowledge is required: technical, SHEQ?)

Removing any other people's lockout could expose them to possible serious injury /death. The check is to ensure all guards, safeguards, etc are correctly in place awaiting the equipment reenergising. This provides a warning to the other people to move away from the equipment which is planned to be re-energised / started. This is an OHSAct requirement for all people to be cleared away before start-up. All insulation means have to be removed to ensure equipment correct operation on re-start-up The person removing another's lockout can face prosecution should an injury incident occur, so every effort to contact the lockout placer should be attempted before the lockout is removed Lockout removal can be prosecuted as a criminal offence under OHSAct. Any energy source without a suitable facility provided for positive lockout, is a potential threat to a lockout person's life

All work is to be checked for being properly done, before re-energising

12.

Inform all people associated with the equipment that the equipment will be reenergised, before the last lockout is removed Person doing the re-energising to ensure all people are safely clear of the equipment before it is started-up Remove all energy isolation or blocking devices and reconnect all energy sources Should the person why fitted and secured a lockout not be available to remove it the manager or supervisor may remove it, provided the pre-restart checks are performed.

15.

16.

Any energy source that does not have suitable or working fittings or facilities to achieve a suitable lockout, should be immediately brought to the manager of supervision's notice Should no physical lockout facility be available on an energy de-energising location, then a lockout tag, must be affixed to the switched off, closed valve or similar device. Only suitably competent persons may be permitted to perform testing on live electrical systems.

17.

A tagout, although not a positive physical lockout, it does provide some protection by informing others that work is being performed so the energy source is de-energised.

Personal Protective Equipment Part 3 - Protecting the head and eyes

DR. BILL POMFRET, MANAGING CONSULTANT, SAFETY PROJECTS INTERNATIONAL, CANADA SPECIALISES IN AUDITING AND EVALUATING BOTH CLIENT AND CONTRACTOR SAFETY PROGRAMMES

AND IN DEVELOPING WITH THEM PRO-ACTIVE PREVENTATIVE SYSTEMS PROCEDURES AND PROGRAMMES TO CONTROL ALL DOWNGRADING INCIDENTS INVOLVING PEOPLE, EQUIPMENT, MATERIALS AND THE ENVIRONMENT.

penetrates it. Impact injuries are associated with such work as grinding, lathe operation and construction. Splashes can harm the eye because of the chemical nature of the liquid, its temperature or the force with which it is propelled - or a combination of these factors. Splashes are associated with jobs that involve handling chemicals. Radiation includes a number of kinds, some naturally occurring, but most in the workplace are man-made: infrared, ultraviolet, laser and microwave. Radiation is associated with the use of welding equipment and furnaces as well as "high-tech" and hospital settings. The types of eye and face protection can be categorised as follows: · Safety spectacles, · Goggles · Welding helmets, face shields and hoods · Full Visor

Protective headwear can reduce the chances of sustaining a skull fracture or brain damage from a blow to the head but it should be a requirement only after every means of designing head-injury hazards out of the workplace has been tried. The class is marked on a label or moulded into the hat or cap, along with the manufacturer's name, date of manufacture and size. This is proof that it has passed a test against impact and (except for Class C) a voltage test, and that it is made of material that is resistant to temperature extremes, fire, water and cleansers and that it is colour-fast. No metal or electrical conductor is permitted in a Class B hat or cap. Safety headwear consists of two basic parts: a seamless, one-piece shell and a shock-absorption system. Although they can affect the degree of protection provided, certain accessories are also allowed: · Chin and nape straps. Keeps hat on when working and in position when bending; · Hearing protection. Earmuffs that are independent of the headwear, that pass through slots, or which are an integrated part of it; · Face shields, welding helmets. These mount on headwear without drilling.

Maintenance

Safety headwear should also be cleaned regularly by using a mild detergent and a damp sponge or soft brush. It should not be left on the dashboard or near the rear window of a vehicle. Nor should it be drilled, padded or otherwise altered; any of these actions could reduce its effectiveness. If unsure that a protective hat or cap is in top shape, replace it. Give safety the benefit of the doubt.

Protecting the eyes

The sources of injuries to the eye can be grouped into three main categories: · Impacts; · Splashes (chemical burns etc.) and · Radiation Impact injuries include the kind that result from a blunt object that compresses the eye, damaging it if the force is sufficient, and those that occur when a sharp object becomes imbedded in the eye or

Such is the variety of safety spectacles now available that they might be mistaken for ordinary eye glasses at first glance. On closer inspection their lenses and frames reveal the manufacture of supplier's monogram, indicating compliance.

Types and classes of approved safety headwear

TYPE 1 TYPE 2 Class A Class B · HAT (Full brin) (SABS) · CAP (With or without peak) · Protects against impact and penetration · Tested at 2,200 v. (not a indication of a safe voltage level.) · Protects against impact and penetration. · Protects against electrical contact with exposed high-voltage conductors. Tested at 20,000 V. (Not an indication of a safe voltage level. · Protects against impact and penetration. · No dielectric protection. · Drilling holes to mount accessories in what was another class of hat also renders it Class C. · · · · Protects against impact and penetration. A wide brim protects ears and neck. Tested at 2,200 v. (not an indication of a safe voltage level.) Includes firelighter's helmets (Type 1.)

Fit

The headband should be adjusted so that the hat stays on when bending over; it shouldn't be so tight that it leaves a mark on the forehead. Any laces should be tied with a reef knot. Warning: As stated earlier, be careful of cheap look-a-like imitations, if it seems light or does not seem normal, have it tested. Class C

The frames are also different from ordinary frames in that they have an eyewear that retains the lens in case of impact. They may have cable temples that curve around the ear to accommodate motion and side shields. Side shields can be or permanently attached or clip-on variety. Of the various styles-- plastic wrap-around, perforated plastic and wire mesh - the wrap-around offer the greatest degree of additional security, but still less than would be provided by goggles. The perforated and mesh kind have better ventilation (and therefore greater comfort and less fogging). Lenses are made of glass, plastic or polycarbonate.

Lens materials and their characteristics

Lens material Glass Impact resistance Good if heattreated Characteristics Scratch resistance Good but loses impact resistance if scratched or pitted. Other Good visual transmission. Good infrared and ultraviolet filtration. Greatest availability of special purpose lenses and tints. Heavier than other materials. Medium priced. Visual transmission almost as good as glass. Least expensive Light in weight.

Polycarbonate

Good

Goggles

Goggles, (eye-cup or cover style) give greater protection than spectacles there are a wide variety of types to offer protection from a range of hazards, including chemicals, molten metal, and dust and flying objects. There are also several kinds of welding goggles, the purpose of each indicated by the lens colour. Plastic

Poor but improved by abrasionresistant coating. Does not loose impact resistance when scratched.

Not as good as More resistant than polycarbonate polycarbonate to pitting from such hazards as sparks from grinders.

More tints available than polycarbonate. Most expensive.

Helmets and faceshields

Helmets are used for welding and working with molten metal. Welding helmets have the same kinds of lenses that welding goggles do. Face shields are worn as protection from chemicals, heat and glare.

Fitting eyewear

Once the kind of protective eyewear appropriate to the task is selected, it must then be properly fitted. Improperly fitting spectacles or goggles - so loose that they slip off or so tight that they cause headaches - may be a safety hazard in themselves, if they are worn at all. Some kinds of eyewear come in one size only, designed to fit the average user. Because not everyone is average, it is a good idea to have users fitted individually by someone who is trained to do so and who is available to make adjustments on the spot. Goggles, helmets, face shields and hoods can all be adjusted to fit properly. Ordinary glasses cannot be used in place of safety eyewear, they must be stamped with the SABS kitemark

For those who require glasses outside of work, there is safety eyewear with approved prescription lenses, as well as safety goggles and visors that fit over prescription glasses. Contact lenses, if their use is permitted, must be worn only with approved eye or face protection in place. Supervisors and safety committee members should be aware of any workers who wear contact lenses, in case of emergency. It should be remembered that eye and face protection is sometimes worn at the same time. It is also sometimes necessary to wear eye and face protection along with other personal protective equipment - hearing protection, respirators, safety helmets and the like. These requirements should be kept in mind when purchases are made or when inspections are undertaken.

Maintenance

Workers should be made aware that safety eyewear can become less effective through rough or careless handling and so needs frequent inspection. To prevent scratching, lenses should be cleaned with tap water or a lens cleaning

solution, not wiped dry. (Dry lens cleaning systems can be used for some types of lenses.) When scratched or pitted, vision is affected and, if the lenses are glass, impact resistance is lowered. To prevent damage to lenses users should be issued cases along with the eyewear, as well as lens-cleaning kits if there are no lens-cleaning stations. If lenses or frames should become damaged they should be repaired if possible, or replaced.
