BUCKNELL UNIVERSITY HAZARD COMMUNICATION PROGRAM POLICY STATEMENT

PURPOSE: To ensure that information about known chemical hazards in use at Bucknell University is disseminated to employees in accordance with the Occupational Safety and Health Administration (OSHA) Hazard Communication Standard, Title 29 Code of Federal Regulations ­ 29 CFR 1910.1200 Subpart Z. POLICY AND SCOPE: This policy applies to all departments and work operations where employees may be exposed to hazardous chemicals or substances under normal working conditions or during emergency situations. Directors of Administrative Departments, Chairpersons of Academic Departments, and their staff are charged with implementing this program in their respective divisions. PROGRAM ADMINISTRATION: James McCormick, Safety Manager, Department of Safety Services, Geiger Service Building, Room 116 is the program coordinator, acting as the representative of the Vice President for Finance and Administration who has overall responsibility for the program. The Safety Manager will review and update the program as necessary. Under this program, employees are to be informed of the contents of the Hazard Communication Standard, the hazardous properties of chemicals or chemical products with which they work, safe handling procedures, and measures to take to protect themselves while they are working with these chemicals or products. They will also be informed of hazards associated with non-routine tasks and chemicals in unlabeled pipes and stationary containers. This program is based on a simple concept ­ that employees have a right to know about the chemical hazards in the workplace. The Bucknell University Hazard Communication Program is based upon the team approach, an approach that nurtures mutual trust, a collective pride in our institution, and a genuine concern for the health and safety of the campus community. Any employee, or their designated representative, can obtain additional information about the program by contacting James McCormick, Safety Manager, Department of Safety Services.

David J. Surgala Vice President for Finance and Administration

MATERIAL SAFETY DATA SHEETS (MSDSs)

A Material Safety Data Sheet (MSDS) is a document that describes the physical and chemical properties of products, substances, and chemicals, their physical/health hazards, and precautions for their safe handling and use in the workplace. The University relies on the chemical manufacturers, distributors, and importers to perform hazard determination/evaluation on the chemical products they produce. The manufacturer, distributor, or importer is responsible to insure the MSDS conforms to OSHA requirements, and to provide a Material Safety Data Sheet for each hazardous chemical product purchased by the University. If there is a revision or change in the MSDS information, then the manufacturer, distributor, or importer is required by Federal law to issue an updated MSDS to the University. The Safety Services Coordinator, Department of Safety Services, will maintain a master file of Material Safety Data Sheets. The MSDSs are stored electronically, by work location, in the Department of Safety Services office and in paper form in the Dispatch area, Department of Public Safety. The paper files are available 24/7/365 to employees covered by the Hazard Communication Program. In addition to the master file, the Safety Services Coordinator will provide binders with chemical product inventory lists and corresponding MSDSs to each work location where employees are routinely exposed to hazardous substances. The inventory lists and MSDSs will be arranged in alphabetical order for ease of identification. All work location binders will be clearly labeled with the University's Hazard Communication Program cover (yellow background with black lettering). Supervisory personnel in each work location will place the binder in a central area that is easily accessible to all employees during each scheduled work shift. Employees may access this information, without supervisory approval, at any time. An employee or their representative may request a copy of a Material Safety Data Sheet (MSDS). The employee or representative will be required to complete a request form, which can be obtained in the Department of Safety Services office or the Dispatch area of the Department of Public Safety. The original completed form will be retained in the Dispatch area. A blank request form (for informational purposes) is included in this section. Directors, Chairpersons, Supervisors, and individuals that purchase or authorize the purchase of hazardous chemical products for use by employees are responsible to obtain MSDSs for those chemicals. If the individual responsible for the purchase of the chemical or product is unable to obtain a Material Safety Data Sheet, that individual must contact the Safety Manager or Safety Services Coordinator for assistance. The Safety Services Coordinator will contact the manufacturer, distributor, or importer to obtain the MSDS. Documentation on efforts to obtain MSDSs will be maintained/retained in the Department of Safety Services office. Whenever possible, MSDSs are to be obtained/reviewed prior to purchase of the chemical product. Chemicals or products that introduce a new hazard into the work area are to be held in storage until the MSDS is received and the employees using the chemical product are

trained. Supervisory personnel are responsible to train affected employees on use of and hazards associated with the new chemical product. Supervisory personnel are responsible to add new/revised/updated copies of the MSDSs and chemical/product inventory lists to the work area binders and/or files where the chemicals or products will be used. When a new or revised MSDS arrives with shipment of the chemical product, it is the supervisor's or designated staff member's responsibility to forward the original document to the Safety Manager or Safety Services Coordinator. The Safety Services Coordinator will update the central MSDS files and hazardous chemical product list whenever a new/revised MSDS is received in the Department of Safety Services office. The Safety Manager will insure that Material Safety Data Sheets are retained for a period of at least thirty (30) years.

A sample MSDS is included with this section.

LABELS AND OTHER FORMS OF WARNING

Federal regulations require all containers (original as well as transfer/temporary storage containers) used in the storage and transportation of hazardous/toxic chemicals and products must be labeled, tagged, or marked with the following information: · · · Identity of the hazardous or toxic chemical product(s); Appropriate hazard warning, and; The name and address of the manufacturer/supplier or individual responsible for the hazard information.

In some cases, this regulation is satisfied by the warning information that is printed on the chemical product label. However, there are some older chemical products that do not contain this information on the label. In this situation, the supervisory personnel or a designated employee will be responsible for the identification and labeling of these chemical products. Labeling information for the chemical product can be found on the MSDS. Do not assume that all employees will be aware that a chemical product contains a hazardous substance even though it is unlabeled. Labels provide an immediate warning to employees regarding workplace chemical hazards. Labels also furnish a link to a more detailed information base available through Material Safety Data Sheets. The University will rely on manufacturers, suppliers, or importers of hazardous chemical products to conform to the OSHA labeling requirements for purchases made by the University. Bucknell employees are prohibited from removing, defacing, or altering manufacturer labels on incoming chemicals or products. ALL transfer or temporary storage containers are to be labeled. Labels must be in English, list the chemical identity (or product name), appropriate hazard warnings, and (when possible) the name and address of the manufacturer, supplier, or importer. Any individual who transfers chemical products from a labeled container to an unlabeled container is responsible to mark the unlabeled container with the information required in the Hazard Communication Standard. An exception to this rule is when an employee will be using the transferred chemical product in the container immediately for his or her own use and there will be no liquid or residue left in the container after the initial use. In situations where transfer/temporary containers are too small to accommodate a legible label, a tag, sign, or ticket with the required information should be attached to the containers. If this is not possible, containers should be grouped together by hazard class and identified with markings or some form of identification that satisfies the OSHA requirements. Supervisory personnel or their designated employees are responsible for ensuring that all transfer or temporary containers are properly labeled. The contents of unlabeled stationary containers, pipes, or piping systems will be described in training sessions given by supervisory personnel.

LABELING SYSTEMS There are several systems and standards accepted by OSHA to satisfy labeling requirements. Each system and standard has unique advantages and limitations. To fulfill government regulations for labeling, manufacturers, suppliers, and importers use different systems/standards. The following listing identifies each system or standard used today: ANSI Z129.1 - 2006 ­ Precautionary labeling for hazardous materials has been developed by the Chemical Manufacturers Association (CMA) and the American Conference on Chemical Labeling. This system has been adopted as American National Standards (Z129.1) by the American National Standards Institute (ANSI). This precautionary labeling contains the name of the chemical, a signal word such as WARNING or DANGER, the key hazard such as FLAMMABLE or VAPOR HARMFUL, and statements of precautions to avoid the hazard. The use of a single term will not always provide adequate information because many chemicals have multiple hazards. Another problem is that the term corrosive includes materials that may be incompatible with one another. For example, strong mineral acids (hydrochloric acid) and strong alkaline materials (sodium hydrochloride) are both corrosives but if they mix during storage or use, they will react vigorously. NFPA 704 - 2007 ­ The National Fire Protection Association (NFPA) has developed a color-coded system called NFPA 704. The system uses a color coded diamond with four quadrants in which numbers are used in the upper three quadrants to signal the degree of emergency ­ health hazard (blue), fire hazard (red), and reactivity hazard (yellow). The bottom quadrant is used to indicate water reactivity, radioactivity, biohazards, or other special hazards. The emergency hazards are listed on a numerical scale of 0 to 4. 0 = no unusual hazard, 1 = minor hazard, 2 = moderate hazard, 3 = severe hazard, and 4 = extreme hazard. The NFPA diamond is used primarily by emergency response personnel and for emergency planning. This system does not adequately inform of occupational hazards or precautionary information. The NFPA system is good for alerting personnel to the degree of the hazard associated with the chemical and helpful in alerting personnel to emergency equipment and storage needs. DOT ­ 2004 Emergency Response Guidebook ­ The Department of Transportation (DOT) hazard labeling system uses a color-coded diamond in which there is a symbol and a term describing the major hazard of the material. DOT hazard classes include: explosive, gases (flammable, non-flammable, corrosive, and poison), flammable liquid, flammable solids, oxidizers, poisons, radioactive materials, and corrosives. Most chemicals are rated by what the DOT considers to be the single major hazard, but many chemicals have subsidiary hazard categories as well. The DOT system is used for the transportation of hazardous materials. HMIS III ­ The National Paint & Coatings Association (NPCA) Hazardous Materials Information System (HMIS) is one of the most widely used systems for labeling hazard chemicals. The system uses standard labels to communicate hazards through the use of colors, numbers, letters of the alphabet, and symbols. The HMIS is a five-part rectangle that provides identification of the chemical, acute health hazards, flammability, physical hazard, personal protective equipment designations, and chronic health hazard data. The chemical identity is conveyed by the chemical name and should be the same as the name

on the MSDS. Acute health hazards (blue), flammability (red), and physical hazard (orange) are communicated by numerical ratings similar to the NFPA system. An alphabetical designation is used to denote recommended personal protective equipment. Chronic health hazards may be any abbreviated technique, such as an asterisk, placed on the label referencing to refer to the specific MSDS associated with the chemical, or the actual chronic information may be written on the label if space allows. Examples of the above listed systems and standards are included in this section.

ANSI Z129.1 - 2006

Hazardous Industrial Chemicals ­ Precautionary Labeling Abstract - Establishes guidelines for the preparation of precautionary information on hazardous chemicals, as defined in the Standard, which is placed on container labels intended for industrial use. It also defines criteria necessary for assessing hazards that determine which, if any, precautionary information should be placed on the label and other forms of labeling. Labeling includes container labels and other documents that contain precautionary and hazard communication information, such as product literature, technical brochures, and material safety data sheets (MSDSs). The Standard must be applied in a manner that is consistent with all statutory and regulatory requirements, such as OSHA's Hazard Communication Standard; it is not the intent of the Standard to substitute for these requirements, or to list each and every unique requirement. What signal words to use for a Right-To-Know label DANGER! For the most severe and immediate hazards, according to ANSI Z129.1, use this term with the following hazards: Extremely flammable liquid Flammable gas Pyrophoric solid Oxidizer Corrosive to living tissue Highly toxic (poison) by inhalation, absorption, or ingestion

WARNING! According to ANSI Z129.1, use this term with the following hazards: Flammable liquid Flammable solid Irritant, severe respiratory Irritant, severe skin Irritant, severe eye Toxic by inhalation Toxic by absorption Toxic by ingestion Sensitizer, skin

CAUTION! Least severe immediate hazards. According to the ANSI Standard, the word CAUTION is assigned to the following hazards:

Combustible liquid Irritant, moderate respiratory Irritant, moderate skin Irritant, defatting skin Irritant, moderate eye Potential suffocation Harmful by absorption Harmful by ingestion

ANSI Label Example: Plate-X Gold Plating Solution DANGER ! May be fatal if swallowed, inhaled, or absorbed through the skin.

Do not breathe vapor or mist. Do not get into eyes, on skin, or on clothing. Exposure causes weakness, headache, cyanosis, loss of consciousness, respiratory arrest, or death. Target organs ­ blood, metabolic enzymes, skin, lungs. Physicians ­ treat exposure victims for cyanide poisoning. Refer to Material Safety Data Sheet for additional information.

NFPA 704 - 2007

Hazard Identification System The National Fire Protection Agency (NFPA), in section 704 of the National Fire Code, specifies a system for identifying the hazards associated with materials. Although the system was developed primarily with the needs of fire protection agencies in mind, it is of value to anyone, including someone enrolled in a science laboratory course that needs to handle potentially hazardous material. The hazard identification signal is a color-coded array of four numbers or letters arranged in a diamond shape. An example is shown below. You will see hazards like this on trucks, storage tanks, bottles of chemicals, and in various other places around campus and around town. The fields in the diamond are color-coded blue, red, and yellow fields (health, flammability, and reactivity).

NFPA Hazard Identification System Flammability Susceptibility of Material to Burning (Red)

0 1 2 3 4

Material will not burn. Material must be pre-heated before ignition can occur. Material must be moderately heated or exposed to relatively high ambient temperature before ignition can occur. Liquids and solids that can be ignited under almost all ambient temperature conditions. Materials that will rapidly or completely vaporize at atmospheric pressure and normal ambient temperature, or that are readily dispersed in air, and that will burn readily.

Example: water Example: corn oil Example: diesel fuel oil Example: gasoline Example: propane gas

NFPA Hazard Identification System Health Hazard Type of Possible Injury (Blue)

0 1 2 3 4

Material that on exposure under fire conditions would offer no hazard beyond that of ordinary combustible material. Material that on exposure would cause irritation but only minor residual injury. Material that on intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. Material that on short exposure could cause serious temporary or residual injury. Material that on very short exposure could cause death or major residual injury.

Example: peanut oil

Example: turpentine Example: ammonia gas

Example: chlorine gas Example: hydrogen cyanide

NFPA Hazard Identification System Reactivity Susceptibility of Material to Burning (Yellow)

0 1 2

3 4

Material that in itself is normally stable, even under fire exposure conditions, and is not reactive with water. Material that in itself is normally stable, but which can become unstable at elevated temperatures and pressures. Material that readily undergoes violent chemical change at elevated temperatures and pressures or which reacts violently with water or which may form explosive mixtures with water. Material that in itself is capable of detonation or explosive decomposition Material that in itself is readily capable of detonation or of explosive decomposition or reaction at normal temperatures and pressures.

Example: liquid nitrogen

Example: phosphorus (red or white) Example: calcium metal

Example: fluorine gas Example: trinitrotoluene (TNT)

NFPA Hazard Identification System Special Precautions Protective Gear Required (White) Special Precaution and Protective Gear Required The fourth, white, field of the hazard signal can have variable content, depending on who prepared the signal. The 1995 edition of the National Fire Codes (Section 704, Chapter 5) specifies only two symbols. Additional symbols are commonly included. The field may also be left blank if no special hazards are present.

Symbols Specified in National Fire Codes, Section 704

W OX

Material shows unusual reactivity with water (i.e. don't put water on it). Material possesses oxidizing properties.

Example: magnesium metal Example: ammonium nitrate

Other Symbols Commonly Used

ACID ALK COR

Material is an acid. Material is a base (alkaline). Material is corrosive.

Material is radioactive.

Department of Transportation (DOT) North American Emergency Response Guidebook - 2004 Description and Examples of Placards

5

The 2004 North American Emergency Response Guidebook (ERG2004) was developed jointly by Transport Canada (TC), the U.S. Department of Transportation (DOT), the Secretariat of Transport and Communication of Mexico (SCT) and with the collaboration of CIQUIME (Centro de Informacion Quimica para Emergencias) of Argentina, for use by fire fighters, police, and other emergency services personnel who may be the first to arrive at the scene of a transportation incident involving dangerous goods. It is primarily a guide to aid first responders in quickly identifying the specific or generic hazards of the material(s) involved in the incident, and to protect themselves and the general public during the initial response phase of the incident.

Examples of Placards Used by DOT:

As a reference tool, a copy of the 2004 North American Emergency Response Guidebook is located in the Department of Safety Services office.

Hazardous Material Information System (HMIS III)

The Hazardous Material Information System (HMIS III) is a labeling system developed by the National Paint and Coatings Association (NPCA). The system uses a label with four color bars and a space at the top where the name of the chemical should be written. The blue, red and orange colored bars indicate, respectively, the health, flammability, and physicals hazards associated with the material. These three bars use a numbering scale ranging from 0 to 4. A value of zero means that the material poses essentially no hazard; a rating of four indicates extreme danger. Although the details of how numbers are assigned may vary somewhat between systems, this is essentially the same overall scheme as used in the NFPA system. A discussion of health hazards and the terminology used to describe them is given in Appendix A of the OSHA Hazard Communication Standard (29 CFR 1910.1200 Appendix A). The fourth, white bar is marked "personal protection" in the HMIS system. A letter is placed in this bar to indicate the kind(s) of personal protective equipment (PPE) that should be used in order to handle the material safely. The letters used are A through K and X. The letter codes are augmented with icons or pictograms showing the types of PPE to be used. The revised HMIS III system (2006) now includes a second box on the blue (health) bar. If this second box shows an asterisk (*), the health hazard associated with the material is a chronic or long-term hazard.

HMIS I & II

HMIS III

HMIS® labels can appear in a variety of formats. Some will include additional spaces to list target organ effects, a labeling requirement under the HCS, and other information, but the four colored areas shown here will always be present. The new HMIS III label provides employees the tools to understand and handle chemicals exhibiting a variety of physical hazards with a far greater degree of precision. Although "Reactivity" has provided useful information for physical hazards, HMIS® III now provides more information about a chemical's physical hazard(s). The new HMIS III not only specifically incorporates each hazard with specific criteria to evaluate the degree of hazard, but also permits employers to identify the hazard present with an icon or symbol. Under the new HMIS® III, a worker can know immediately, for example, that a material he is handling is rated as an explosive, and that it is rated as a "3" giving him or her much more precise and useful information about the safe handling of that material.

HMIS® labels can appear in a variety of formats. Some will include additional spaces to list target organ effects, a labeling requirement under 29 CFR 1910.1200, and other information, but the four colored areas shown here will always be present. An older style HMIS® label is shown below on the left. In the April 2002 release of HMIS® III the yellow Reactivity section was replaced with an orange Physical Hazard section as shown below on the right. Other aspects of the system were also changed (see below).

NPCA recommends upgrading your older HMIS labels.

MSDS Relevance

Specific sections of an HMIS® label include the following:

Health

The Health section conveys the health hazards of the material. In the latest version of HMIS®, the blue Health bar has two spaces, one for an asterisk and one for a numeric hazard rating. If present, the asterisk signifies a chronic health hazard, meaning that long-term exposure to the material could cause a health problem such as emphysema or kidney damage. NFPA lacks this important information because the NFPA system is meant only for emergency or acute (shortterm) exposures. According to NPCA, the numeric hazard assessment procedure is different than that used by NFPA. Here are the numeric rankings for the HMIS system:

4 3 2 1 0

Life-threatening, major or permanent damage may result from single or repeated overexposures. Major injury likely unless prompt action is taken and medical treatment is given. Temporary or minor injury may occur. Irritation or minor reversible injury possible. No significant risk to health.

Flammability

For HMIS I and II, the criteria used to assign numeric values (0 = low hazard to 4 = high hazard) are identical to those used by NFPA. In other words, in this category, the systems are identical. For HMIS III, the flammability criteria are defined according to OSHA standards:

4 3

Flammable gases, or very volatile flammable liquids with flash points below 73 °F, and boiling points below 100 F. Materials may ignite spontaneously with air. (Class IA) . Materials capable of ignition under almost all normal temperature conditions. Includes flammable liquids with flash points below 73 °F and boiling points above 100 °F, as well as liquids with flash points between 73 °F and 100 °F. (Classes IB & IC).

2 1 0

Materials which must be moderately heated or exposed to high ambient temperatures before ignition will occur. Includes liquids having a flash point at or above 100 °F but below 200 °F. (Classes II & IIIA). Materials that must be preheated before ignition will occur. Includes liquids, solids and semi solids having a flash point above 200 °F. (Class IIIB). Materials that will not burn.

Reactivity (HMIS® I and II - now obsolete)

The criteria used to assign numeric values (0 = low hazard to 4 = high hazard) were identical to those used by NFPA. In other words, in this category, the systems were identical. This version is now obsolete. The yellow section has been replaced with an orange section titled Physical Hazards - see the next section for more information.

Physical Hazard (HMIS® III)

Reactivity hazard are assessed using the OSHA criterion of physical hazard. Seven such hazard classes are recognized: Water Reactives Organic Peroxides Explosives Compressed gases Pyrophoric materials. Oxidizers Unstable Reactives This version replaces the now-obsolete yellow section titled Reactivity see the previous section for more information. As with the Health and Flammability sections, the level of hazard is indicated using numeric values (0 = low hazard to 4 = high hazard):

4

Materials that are readily capable of explosive water reaction, detonation or explosive decomposition, polymerization, or self-reaction at normal temperature and pressure. Materials that may form explosive mixtures with water and are capable of detonation or explosive reaction in the presence of a strong initiating source. Materials may polymerize, decompose, self-react, or undergo other chemical change at normal temperature and pressure with moderate risk of explosion. Materials that are unstable and may undergo violent chemical changes at normal temperature and pressure with low risk for explosion. Materials may react violently with water or form peroxides upon exposure to air. Materials that are normally stable but can become unstable (self-react) at high temperatures and pressures. Materials may react non-violently with water or undergo hazardous polymerization in the absence of inhibitors. Materials that are normally stable, even under fire conditions, and will not react with water, polymerize, decompose , condense, or self-react. Nonexplosives.

Personal Protection

This is by far the largest area of difference between the NFPA and HMIS® systems. In the NFPA system, the white area is used to convey special hazards whereas HMIS® uses the white section to indicate what personal protective equipment (PPE) should be used when working with the material.

Note: The NPCA specifically recommends that "preparers of MSDSs should not place HMIS® PPE designation codes on the MSDSs or labels that leave the facility, as they do not know the conditions under which their customers use those products." However, these still turn up on some MSDSs. HMIS® uses a letter coding system for this section. Note: Some of the letters/symbols used in this table are also used as TSCA, CHIP, and/or DoD HMIRS/HCC codes, all of which have completely different meanings and applications!

NOTE: NFPA and other labeling codes (such as HMIS®) are NOT required by OSHA. OSHA has said "...OSHA does not endorse specific services or products. It would, therefore, be inappropriate for OSHA to require a particular labeling system's code on the material safety data sheet." (see this official OSHA interpretation). OSHA does have specific labeling requirements that must be fulfilled, but there is no specified format code system required.

Similarities and Differences between the NFPA and HMIS Hazard Labeling Systems

Both the NFPA Hazard Identification System and the Hazardous Material Information System (HMIS) may be used to comply with the Standard's labeling requirements. These systems, although similar, differ in some important aspects.

Similarities Both systems have three color-coded fields to indicate the flammability (red), health (blue), and reactivity (yellow) (physical hazard ­ orange for HMIS III) hazards associated with the material.

Both use a system of five numbers, ranging from 0 to 4, to indicate the severity of the hazard, with 0 being the lowest amount and 4 being the most hazardous.

Differences They differ in layout ­ NFPA uses four diamonds, HMIS uses vertically stacked bars. They differ in interpretation of the fourth, white field (special handling in the NFPA system, protective equipment in the HMIS system). Possibly the most significant difference, however, is the intended audience for each of the systems. HMIS was developed as a Hazard Communication Standard compliance tool, and the intended audience is employees who must handle hazardous chemicals in the workplace. The NFPA system was designed to alert fire fighters arriving on the scene of a fire to the hazards associated with the materials present at that location. Therefore, the numbers assigned in the NFPA system assume that a fire is present. No such assumption is indicated in the HMIS system. For this reason, the numbers that are assigned to the flammability, health, and reactivity hazards may differ between the NFPA and HMIS systems, even for the same chemical or material.

HEALTH AND PHYSICAL HAZARD CLASSIFICATION

HEALTH HAZARDS Materials that have one or more of the following characteristic properties are covered by the Hazard Communication Standard: · Irritations · Corrosives · Cutaneous Hazards · Nephrotoxins · Carcinogens · Highly Toxic Agents · Reproductive Toxins · Sensitizers · Toxic Agents · Neurotoxins · Blood Acting Agents ·Hematopietic System Agents · Hepatoxins · Eye Hazards

· Agents that damage the lungs, skin, or mucous membranes Health hazards are divided into two categories ­ acute and chronic health hazards. There have been many attempts to categorize health effects and to define them in various ways. Generally, the terms acute and chronic are used to delineate between health effects based on severity and duration. Acute hazards usually occur rapidly as a result of a short-term exposure to a chemical or substance. Chronic hazards have a long-term effect, essentially permanent. Their effects may be slow to develop, and often result from repeated or continuous exposure over an extended period of time. PHYSICAL HAZARDS A chemical or substance is considered a physical hazard when there is scientific valid evidence that it is one of the following and as such is included in the Hazard Communication Standard: · Combustible Liquid · Flammable Aerosol · Flammable Solid · Pyrophoric · Compressed Gas · Flammable Gas · Organic Peroxide · Unstable Reactive · Explosive · Flammable Liquid · Oxidizer · Water Reactive

Refer to your Hazard Communication Program guidebook for a more detailed explanation on health and physical hazards.

NON-ROUTINE TASKS

University employees who are required to perform hazardous, non-routine tasks or projects (duties that are not specified in their position descriptions) will be given training sessions by supervisory personnel prior to starting this type of work. The nonroutine training session will include: specific chemical exposure hazards of the task or activity, protective and safety measures to follow, spill or leak cleanup procedures, and proper precautions used to avoid or reduce exposure.

OUTSIDE CONTRACTOR NOTIFICATION

Definition of a multi-employer workplace ­ a company or business that utilizes other non-company employees (including contractors and temporary services) in daily functions. The University utilizes various outside contractors to assist in maintaining buildings, grounds, and equipment. When this occurs, the University is considered a "multiemployer workplace". The Safety Manager, Department of Safety Services, is responsible to develop and implement a system whereby contractors are informed of the hazardous chemicals in use in areas where the contractors' employees may be exposed. To ensure that any outside contractors work safety in any University owned or operated facility, the Safety Manager will be responsible to provide the contractor with the following information upon request: · · · A copy of the University's Hazard Communication Program along with a copy of the Workplace Chemical List; The location of the MSDS files; and, Information and location for any hazardous substances to which they may be exposed while working on the job site.

Outside contractors are required to review this information with their employees prior to the start of work at the University. It will be the responsibility of the contractor to notify the Safety Manager or University Management overseeing the job site of any hazardous chemicals or substances that may be brought onto the job site. This information will need to be provided to any University employee working at the job site. Purchasing agents of the University are responsible to convey this information to all outside contractors.

Employee training will consist of the University's Hazard Communication training/information guidebook, audiovisuals that explain, in detail, each section of a material safety data sheet, and review various labeling systems used by manufacturers/suppliers or importers. Classroom, small group, work team, and individual training will be utilized when appropriate. The Director, Human Resources, is responsible to ensure those new employees and internal transfer employees receive Hazard Communication training. The Safety Manager will identify job titles that require Hazard Communication training and will provide the Director of Human Resources with the appropriate training materials. The Safety Manager or Supervisory staff members will provide initial training to employees who work with or are potentially exposed to hazardous chemical substances in their work areas. Supervisory staff will train employees on the hazardous chemical substances that they work with, or are exposed to in performing their duties or as a result of hazardous chemical substances being introduced into the work area by another employer. Supervisory staff will re-train employees when new hazards are introduced into the work area. The Safety Manager will review the training program(s) and update/revise as necessary. The Safety Manager/Supervisory staff will monitor employee work habits/performance to determine the effectiveness of the training. Human Resources and Supervisory staff will maintain/retain documentation of employee training records.

SUMMARY OF BUCKNELL UNIVERSITY'S HAZARD COMMUNICATION PROGRAM

Bucknell University's Hazard Communication Program is designed to transmit information regarding the proper use of, and hazards associated with chemicals or products in the workplace. The written program is designed to provide a brief summary of information that is covered in detail in the guidebook distributed to Bucknell University employees covered under the Hazard Communication Standard. The written program consists of the following elements: · · · · · · · · · · · Purpose, policy, and scope of Hazard Communication at Bucknell; Information page; Explanation of written program; Workplace chemical/substance list; Material Safety Data Sheets (MSDSs); Labels and other forms of warning; Health and physical hazard classification; Non-routine tasks; Outside contractor notification; Employee training and information; Summary of Bucknell's Hazard Communication Program.

The Hazard Communication Program will be a continuing educational and informational process at the University. Compliance with the Hazard Communication Standard is not a one-step process but rather an ever-evolving procedure that incorporates both government regulations and University policies/procedures to ensure a safer working environment for employees. For any health and safety program to be successful, a commitment is necessary from every level of the University community. This is particularly true for the Hazard Communication Program since its success is based on a required change in behavior and attitude of affected employees. Following safe practices by reading labels and MSDSs before using new chemicals or products, using personal protective equipment when necessary, and consulting your supervisor if the information provided is still not clear will decrease the risk of accidents or injuries to all employees. Remember ­ chemical safety begins with you! If you require additional information regarding Bucknell University's Hazard Communication Program, contact the Safety Manager, Department of Safety Services, Geiger Service Building, Room 116.
