  • Bloodborne Pathogen Plan -- Westmont College Plan which limits occupational exposure to blood and other potentially infectious materials since.
  • Cal/OSHA Action Level -- the exposure level (concentration of the material in air) at which Cal/OSHA regulations to protect employees take effect.
  • Cal/OSHA Regulated Carcinogen -- A Carcinogen specifically listed in 8 CCR 5209
  • Carcinogen -- A substance or agent capable of causing or producing cancer in mammals, including humans. A chemical is considered to be a carcinogen if:
  • Chemical Hygiene Plan -- A written program that sets forth policy and procedures capable of protecting employees from the health hazards associated with their workplace.
  • Chemical Waste Program -- Westmont College program designed to properly collect and dispose of hazardous waste.
  • CFR -- Code of Federal Regulations.
  • CHO -- See SO/CHO
  • Department Safety Plan -- A written plan for each Department including specific information, safety rules, standard operating procedures, waste disposal programs and chemical inventories. Must be reviewed and updated annually.
  • DOSH-- Division of Occupational Safety and Health.
  • EPA -- US Environmental Protection Agency.
  • Exposure Limits -- The concentration in air of a chemical in the workplace that is thought to be acceptable.
  • Hazard Assessment -- Determination of the potential health hazards associated with an experiment before beginning it.
  • Hazard Communication Program -- Westmont College Program which includes employee training, access to information about chemical products used in the workplace, access to personal protective equipment (PPE), and a written Hazard Communication Plan
  • Hazardous Chemical (as defined in 8 CCR 5191) -- A chemical for which there is statistically significant evidence based on at least one study conducted in accordance with established scientific principles that acute or chronic health effects may occur in exposed employees (includes carcinogens, toxic or highly toxic agents, reproductive toxicants, irritants, corrosives, sensitizers, hepatoxins, nephrotoxins, neurotoxins, agents which act on the hematopoitic systems, and agents which damage the lungs, skin, eyes, or mucous membranes).
  • Hazardous Material -- Includes Hazardous Chemicals, Biohazards and Radioactive Materials.
  • HEPA filter -- High-efficiency particulate air-purifying filter.
  • High Hazard Chemical (as defined in 8 CCR 5191) -- A select carcinogen, reproductive toxicant or substance that has a high degree of acute toxicity (causes severe and immediate health effects from limited exposure).
  • Highly Toxic -- A chemical falling within any of the following categories:
    • A chemical with a median lethal dose (LD50) of 50 mg or less per Kg of body weight when administered orally to albino rats weighing between 200 and 300 gm each.
    • A chemical with a median lethal dose (LD50) of 200 mg or less per Kg of body weight when administered by continuous contact for 24 hours (or less if death occurs within 24 hours) with the bare skin of albino rabbits weighing between 2 and 3 Kg each.
    • A chemical that has a median lethal concentration (LC50) in air of 200 ppm by volume or less of gas or vapor, or 2 mg per liter or less of mist, fume, or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats weighing between 200 and 300 gm each.
  • HVAC -- Heating, ventilation air-conditioning system.
  • Health Hazards -- Have properties capable of producing adverse effects on the health and safety of a human.
  • HR -- The Human Resources Department at Westmont College.

  • NIOSH -- National Institute for Occupational Safety and Health, US Public Health Service, US Department of Health and Human Services (DHHS), which among other activities, tests and certifies respiratory protective devices and air sampling detector tubes, recommends occupational exposure limits for various substances, and assists OSHA and MSHA in occupational safety and health investigations and research.
  • OSHA -- Occupational Safety and Health Administration, US Department of Labor. Sometimes referred to as Fed OSHA or Federal OSHA to distinguish it from Cal/OSHA.
  • PEL -- Permissible Exposure Limit is an exposure limit established via OSHA'S regulatory authority. It may be a time weighted average (TWA) limit or a maximum concentration exposure limit.
  • Physical Hazard -- The Physical Hazards of a chemical are combustible, flammable, compressed gasses, explosives, organic peroxides, oxidizers, pyrophoric, unstable (reactive) or water-reactive.

  • Reproductive Toxin -- A chemical which affects the reproductive system and may produce chromosomal damage (mutation) and/or adverse effects on the fetus (teratogenesis). For the purposes of this guidance, any chemical with a mutagenic or teratogenic quotation in the Registry of Toxic Effects of Chemical Substances (RTECS) shall be considered a reproductive hazard.
  • Respirator -- Devices that will protect the wearer's respiratory system from overexposure by inhalation to airborne contaminants. Respirators (or other Respiratory protection such as SCBAs) are used when a worker must work in an area where he/she might be exposed to concentration in excess of the allowable exposure limit.
