Fire precautions and protective measures:
Fire personnel should wear air breathing apparatus, wear full fire clothing, and fight fire upwind.
If possible, move the container from the fire to an open area.
Containers in the fire area must be evacuated immediately if they are discolored or emit sound from the safety relief device.
Isolate the accident site and prohibit irrelevant personnel from entering.
Contain and treat fire water to prevent environmental pollution.
Keep the storage unit sealed, stored in a cool, dry place, and ensure that the work room has good ventilation or exhaust. It should be stored separately from oxidants, acids and edible chemicals, and should not be mixed.
