Dry chemical, alcohol-resistant foam, carbon dioxide
FIRE FIGHTING INSTRUCTIONS
Extinguish fire surely from the windward of it with a respirator, because toxic gas may be produced.
Extinguish a small-scale fire with a fire extinguishing agent or sand. Extinguish a large scale fire by injecting a fire-extinguishing agent into the tank for intercepting air and sprinkle water outside the tank for cooling it.

When a fire is caused by the ignition of spilled material, dike it with sand to prevent the fire from spreading and extinguish it with powder, foam or carbon dioxide fire-extinguisher.
6. ACCIDENTAL RELEASE MEASURES
