Fire Safety Considerations

Neat biodiesel can be extinguished with dry chemical, foam, Halon, CO2, or water spray, although the water stream may splash the burning liquid and spread the fire. Oil-soaked rags can cause spontaneous combustion if not handled properly. Before disposal, wash rags with soap and water and dry in a well-ventilated area. Because biodiesel will burn if ignited, keep it away from oxidizing agents, excessive heat, and ignition sources.
