  • Materials and handouts for Presentation:
    Copy of the District’s Program
    Examples of labels, containers, placards, etc.
    MSDSs for typical chemicals in the workplace
    Training sign-in sheets
    Examples of Personal Protective Equipment, such as gloves, coveralls and face shields
  • Important points:
    Hazard Communication or Employee Right to Know was enacted in 1985.
    The purpose of the act is to:
    Protect employees from needless chemical exposure.
    Provide a mechanism for employees to know about the hazards associated with chemicals that they work with.
    The following products are exempt from the act:
    -Hazardous Waste
    -Tobacco or tobacco products
    Wood or wood products
    Foods, drugs or cosmetics
    Retail food sale
    Consumer Products (This applies to chemicals purchased at a consumer store. However, if these products are used in the work environment, they must have a MSDS. For example, bleach purchased at a grocery store will not require a MSDS. But if you use this product in the workplace, the standard applies.)
    The use of a substance in compliance with regulations of the Director of Food and Agriculture.
  • District Program
    OEHS Responsibilities:
    Approves inventory of all chemical products to be used by the District.
    Verifies label information and reviews MSDSs for health and safety information before products are released for use.
    Substitutes chemical products with less toxic products whenever possible.
    Site Responsibilities:
    Maintains an updated inventory of all chemical products on site.
    Requests approval for chemicals not listed in the District’s supplies catalog.
    Notifies OEHS in the event of a hazardous chemical spill.
    Provides or arranges for training.
    Documents training and keeps records on file for 3 years.
  • All original and secondary containers are properly labeled.
    Hazard communication training for new employees.
    Re-training for employees when new hazards are introduced in the workplace.
    Each site shall document hazard communication training and keep on file for three years.
  • Employee Information and Training include:
    Program requirements
    Site hazardous operations (if there are any)
    Location of MSDS and written program
    Label requirements
    District chemical spill procedures
    Other safety instructions
  • Discuss training requirements:
    Example: Employee is hired as a secretary. Receives hazcom training for office products.
    This same employee changes career and becomes an office worker for science chemical plant for the same employer. The job duties now include handling classroom science chemicals. This person needs additional training on potential hazards of job BEFORE they start performing the job duties.
  • All employee training must have proper documentation in the event of a safety audit by the District or outside safety and health organization such as Cal/OSHA.
  • Hazard Terms:
    Corrosives- Materials that burn body tissues, such as Hydrochloric Acid, Sodium Hypochlorite (bleach), Nitric Acid, Sulfuric Acid.
    Flammables-Materials that easily ignite or burn rapidly or intensely such as:
    Acetone, Methanol, Gasoline, Xylene.
    Explosives-Materials that violently release large quantities of gas and heat.
    Many explosions result in fires. Explosion hazards and flammable hazards are frequently considered together.
    Pressure can also be developed in a closed container due to decomposition or reaction of the content. An example of a pressure hazard is broken valve on a compressed gas cylinder. Escaping gas can propel a cylinder like a rocket.
    Toxicity-A substance with the potential of injury by direct chemical action with body systems. Toxic substances interfere with the function of cells in body tissues.
  • The amount of the material to which an individual is exposed to is called the Dose.
    The dose effects are dependent on the concentration of the material that gets into the body over a period of time, or concentration x time.
    The response depends on the dose and the effects on the body. This may lead to irritation, illness or death.
    A high concentration for a short period of time is an acute effect.
    A continued smaller exposure for a long period of time is a chronic effect.
  • All MSDSs must contain information required by OSHA MSDS form 174.
    The Right to Know law requires hazardous substance manufacturers to develop MSDSs for substances they produce or import.
    Distributors also must provide MSDSs.
    MSDSs have been distributed at District sites for the following operations:
    Office Products
    Custodial Products
    Food Services Products
    Maintenance Products
    Automotive Repair Products
    Science Chemical Products
    MSDSs must be available for all employees in their work locations for review during each work shift. If MSDSs are not available, or new hazardous substances are in use, please contact OEHS.
    All District employees have the right to obtain copies of MSDSs without fear of termination, discrimination or retaliation.
  • The MSDS provides the following information:
    This is the information required for OSHA MSDS form 174
  • The first section of the MSDS helps to identify the chemical.
  • This section lists hazardous ingredients and safe exposure concentrations. These exposure limits are usually calculated for 8 hours time weighted average.
    CAS Number: Chemical Abstract Service number. This number (assigned by the American Chemical Society) allows access to specific regulatory information re: the chemical (for example: status as a carcinogen, California Prop. 65 placement, etc.).
    TLV: Threshold Limit Value. The highest concentration of a chemical that an individual can be exposed to at any time during his/her work shift.
    PEL: Permissible Exposure Limit. The highest concentration of a chemical that an individual can be exposed to, averaged over the duration of an 8-hour work shift.
  • This section describes the chemical’s appearance, odor, and other characteristics.
    Vapor Density: The relative weight of a gas or vapor as compared with air.
    Specific Gravity: The relative weight of a liquid as compared with water.
    Solubility in Water: How easily a solid or liquid will dissolve in water.
    Vapor Pressure: The maximum pressure that a vapor can be placed under at a specific temperature before it condenses into a liquid.
  • This section provides information on flammability, combustibility, and ignitability. The proper fire extinguisher type and media is listed in this section.
    Lower Explosion Level (LEL): The lowest concentration (in percent) of a gas or vapor in air at which an explosion can occur if a source of ignition is introduced.
    Upper Explosion Limit (UEL): The highest concentration (in percent) of a gas or vapor in air at which an explosion can occur if a source of ignition is introduced.
    The concentration range between the LEL and the UEL is called the “explosive range”.
    Fire Extinguisher Types:
    A = Solid Combustibles (e.g. trash, wood, paper, many types of chemicals)
    B = Liquids
    C = Electrical
    Fire Extinguisher Media:
    Dry Chemical
  • Flammable – The chemical ignites below 100 degrees Fahrenheit.
    Combustible – The chemical ignites above 100 degrees Fahrenheit.
  • This section lists symptoms of overexposure and emergency medical procedures.
  • This section provides information regarding chemicals that “react” with certain materials or conditions, and may cause a dangerous reaction.
    Stability: The likelihood or probability of a chemical undergoing a violent reaction (e.g. explosion, spontaneous combustion) in response to an environmental stimulus, such as heat, shock, moisture, or another chemical. Ordinary table salt (sodium chloride) is very stable; metallic sodium and chlorine gas are both highly reactive and quite unstable.
    Incompatibility: The probability of two chemicals combining with each other and producing either a dangerous reaction (e.g. fire, explosion, etc.) or a highly toxic by-product (see “bleach and ammonia” , p. 22).
    Hazardous Decomposition: The gradual breakdown of a chemical (e.g. during long storage periods) wherein the formation of unstable chemical by-products may cause spontaneous combustion, an explosion or some other dangerous reaction to occur.
  • Bleach and ammonia mixed together can produce a dangerous (sometimes fatal) gas called phosgene.
  • This section describes accidental spill or leak clean up and safe disposal methods.
  • In the event of a chemical or hazardous material spill, the following steps must be taken:
    Evacuate and prevent access to area.
    Notify the site administrator, supervisor or plant manager about the spill.
    Do not ask custodians or untrained individuals (including students!) to clean the spill.
    Call the Office of Environmental Health and Safety at (213) 241-3199.
  • This section provides a listing of personal protective equipment, ventilation requirements, and other special handling procedures.
  • All chemicals used by the District must have labels on the container.
    Containers should have:
    Appropriate hazard warnings
    Name and Address of the manufacturer
  • Another example of a label with warnings and caution phrases.
  • Fire Department Placard
    This placard is designed to protect fire fighters.
    The colors relate to the reactions of chemicals in fire conditions.
  • In this situation:
    Blue Section -1 (Health Hazard) TYPE of POSSIBLE INJURY: The materials in the building would cause irritation but only minor residual injury, even if no treatment is given.
    Red Section -2 (Flammability) SUSCEPTIBILITY OF MATERIALS TO BURNING: The materials must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur.
    Yellow Section-3 (Reactivity) SUSCEPTIBILITY TO RELEASE OF ENERGY: The materials are capable of detonation or explosive reaction but require one or more of the following:
    A strong initiating source
    Heating under confinement before initiation
    Exposure to water
  • The bottom space is primarily used to identify unusual reactivity with water. A W with a line through its center alerts fire fighting personnel to the possible hazard in the use of water.
    Other example of symbols are shown here.
  • Other colors:
    Yellow – Reactivity
    Blue- Health Hazard
    White- Special precautions
    Other information found on the label:
    Chemical name
    Manufacturer name and address
    First aid information
    Precautionary statements that list specific actions to be taken to avoid the effects of exposure
    Warning statement
  • Consult your supervisor if you have questions about chemical use, hazards or product safety.
    Read and understand all safety instructions and labels carefully before you begin work.
    Maintain safety equipment and tools as required for safe work performance.
    Review MSDSs whenever a new chemical is introduced or if there is a question concerning health/safety characteristics of a chemical already in use.
  • Wear personal protective equipment if required.
    Know what to do in an emergency.
    Know storage and waste requirements for all chemicals.
    Understand and obey the safety rules and regulations that apply to you and your job.
