Hazardous Materials Identification System
Health
- 0. No significant risk to health.
- 1. Irritation or minor reversible injury possible.
- 2. Temporary or minor injury may occur.
- 3. Major injury likely unless prompt action is taken and medical treatment is given.
- 4. Life-threatening, major or permanent damage may result from single or repeated overexposures.
Flammability
- 0. Materials that will not burn.
- 1. Materials that must be preheated before ignition will occur. Includes liquids, solids and semi solids having a flash point above 93 C (200 °F).
- 2. 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 38 C (100 °F) but below 93 C (200 °F).
- 3. Materials capable of ignition under almost all normal temperature conditions. Includes flammable liquids with flash points below 23 C (73 °F) and boiling points above 38 C (100 °F), as well as liquids with flash points between 23 C and 38 C.
- 4. Flammable gases, or very volatile flammable liquids with flash points below 23 C (73 °F), and boiling points below 38 C (100 °F). Materials may ignite spontaneously with air.
Physical Hazard
- 0. Materials that are normally stable, even under fire conditions, and will not react with water, polymerize, decompose, condense, or self-react. Non-explosives.
- 1. 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.
- 2. 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.
- 3. 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.
- 4. Materials that are readily capable of explosive water reaction, detonation or explosive decomposition, polymerization, or self-reaction at normal temperature and pressure.
