B2. | Procedures for Flammable Chemicals In general, the flammability of a chemical is determined by its flash point, the lowest temperature at which an ignition source can cause the chemical to ignite momentarily under certain controlled conditions. |
|
| 1. | Chemicals with a flash point below 200oF (93.3oC) will be considered "fire hazard chemicals". | ||
| 2. | OSHA standards and the National Fire Protection Association (NFPA) guidelines on when a chemical is considered flammable apply to the use of flammable chemicals in the laboratory. In all work with fire-hazard chemicals, follow the requirements of 29 CFR, subparts H and L; NFPA Manual 30, "Flammable and Combustible Liquids Code"; and NFPA Manual 45, "Fire Protection for Laboratories Using Chemicals". | ||
| 3. | Fire-hazard chemicals should be stored in a flammable-solvent storage area or in storage cabinets designed for flammable materials. | ||
| 4. | Fire-hazard chemicals should be used only in vented hoods and away from sources of ignition. | ||
