Evacuate the personnel in the leakage contaminated area to a safe area quickly, isolate them, and strictly restrict access.Cut off the ignition source.It is recommended that emergency personnel wear self-contained positive pressure respirators and fire protection clothing.Cut off the source of leakage as far as possible to prevent it from entering into restricted spaces such as sewers and flood discharge ditches.
Small amount of leakage: absorb or absorb with sand or other incombustible materials.
Large amount of leakage: build a dike or dig a pit to receive;Cover with foam to reduce steam disaster.Spray water cools and dilutes steam, protects on-site personnel, and dilutes leakage into incombustible materials.Use explosion-proof pump to transfer to tank car or special collector for recycling or transport to waste disposal site.
