A cargo hold containing cargo such as nitrates, chlorates etc which produce oxygen under the influence of heat catches fire. How would you deal with this?
Direct Answer
Option B: With this type of material, the hatches should not be battened down. The fire can only be extinguished using large quantities of water
Cargoes such as nitrates and chlorates contain chemical oxidizers that produce oxygen when heated; smothering agents like CO2 are ineffective, so the fire must be fought using large quantities of water for cooling without battening down hatches.
