generation or explosion.); 4 (Water Reactivity: Materials that react 0 (Water Reactivity: Materials that do not react with water. Organic explosively with water without requiring heat or confinement. Organic Peroxides: Materials that are normally stable, even under fire conditions Peroxides: Materials that are readily capable of detonation or explosive and will not react with water. Explosives: Substances that are Non- decomposition at normal temperature and pressures. Explosives: Division 1.1 & 1.2-explosive substances that have a mass explosion Explosive. Unstable Compressed Gases No Rating. Pyrophorics No hazard or have a projection hazard. A mass explosion is one that affects Rating. Oxidizers: No “0” rating allowed. Unstable Reactives: almost the entire load instantaneously. Compressed Gases: No Rating. Substances that will not polymerize, decompose, condense or self-react.); Pyrophorics Add to the definition of Flammability “4”. Oxidizers No “4” rating. Unstable Reactives: Substances that may polymerize, decompose, condense or self-react at ambient temperature and/or pressure and have a high potential to cause significant heat generation or explosion.). PPE Rating B: Hand and eye protection is required for routine chemical use. PPE Rating C: Hand, eye, and body protection may be required for routine chemical use. DEFINITIONS OF TERMS (Continued) NATIONAL FIRE PROTECTION ASSOCIATION HAZARD ECOLOGICAL INFORMATION: RATINGS: EC is the effect concentration in water. BCF = Bioconcentration Factor, HEALTH HAZARD: 0 (material that on exposure under fire conditions which is used to determine if a substance will concentrate in lifeforms would offer no hazard beyond that of ordinary combustible materials); 1 which consume contaminated plant or animal matter. TLm = median (materials that on exposure under fire conditions could cause irritation or threshold limit; Coefficient of Oil/Water Distribution is represented by minor residual injury); 2 (materials that on intense or continued exposure log Kow or log Koc and is used to assess a substance’s behavior in the under fire conditions could cause temporary incapacitation or possible environment. residual injury); 3 (materials that can on short exposure could cause REGULATORY INFORMATION: serious temporary or residual injury); 4 (materials that under very short U.S. and CANADA: exposure could cause death or major residual injury). This section explains the impact of various laws and regulations on the FLAMMABILITY HAZARD AND REACTIVITY HAZARD: Refer to material. ACGIH: American Conference of Governmental Industrial definitions for “Hazardous Materials Identification System”. Hygienists, a professional association which establishes exposure limits. FLAMMABILITY LIMITS IN AIR: Much of the information related to EPA is the U.S. Environmental Protection Agency. NIOSH is the National fire and explosion is derived from the National Fire Protection Association Institute of Occupational Safety and Health, which is the research arm of (NFPA). Flash Point - Minimum temperature at which a liquid gives off the U.S. Occupational Safety and Health Administration (OSHA). WHMIS sufficient vapors to form an ignitable mixture with air. Autoignition is the Canadian Workplace Hazardous Materials Information System. Temperature: The minimum temperature required to initiate combustion DOT and TC are the U.S. Department of Transportation and the Transport in air with no other source of ignition. LEL - the lowest percent of vapor in Canada, respectively. Superfund Amendments and Reauthorization Act air, by volume, that will explode or ignite in the presence of an ignition (SARA); the Canadian Domestic/Non-Domestic
