Fire Fighting Procedures

Tabun is a combustible liquid. Extinguish with alcohol foam, carbon dioxide, or dry chemical. Complete protection required; have available decontaminants (bleach, alkali) and atropine. Bleaching powder (chlorinated line) destroys tabun but gives rise to cyanogen chloride. Poisonous gases including phosphorus oxides, cyanide and nitrogen oxides are produced in fire. Vapors are heavier than air and will collect in low areas. Containers may explode in fire. Storage containers and parts of containers may rocket great distances, in many directions. 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. If employees are expected to fight fires, they must be trained and equipped in OSHA 1910.156.
