Fire Fighting Procedures

Use dry chemical, carbon dioxide, water spray, or alcohol foam extinguisher ... If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors or shows any signs of deforming), withdraw immediately to a secure position ... The only respirators recommended for fire fighting are self-contained breathing apparatuses that have full facepieces and are operated in a pressure-demand or other positive-pressure mode.
If material on fire or involved in fire: Do not use water. Use graphite, soda ash, powdered sodium chloride, or suitable dry powder. If fire is massive, back off, protect surroundings, and let burn. Keep run-off water out of sewers and water sources.
