| NFPA Hazard Classification | 0 - Materials that, under emergency conditions, would offer no hazard beyond that of ordinary combustible materials.1 - Materials that must be preheated before ignition can occur. Materials require considerable preheating, under all ambient temperature conditions, before ignition and combustion can occur.1 - Materials that in themselves are normally stable but that can become unstable at elevated temperatures and pressures. |
