No contact or crossing of leaks.
All equipment used in the operation should be grounded.
Cut the leak as far as possible.
Eliminate all points of fire.
A warning area is designated according to the affected area of liquid flow, steam or dust diffusion, and unrelated personnel are evacuated from the crosswind, upper wind direction to the security zone.
Environmental protection measures:
Containment of leaks to avoid environmental pollution. Prevent leaks from entering sewers, surface water and groundwater.
Storage, removal methods and disposal materials used for leaking chemicals:
Small leakage: as far as possible, the leaking liquid is collected in a closed container. Absorb with sand, activated carbon or other inert materials and transfer to a safe place. Don't go down the drain.
Large number of leaks: build dikes or dig pits. Seal the drain. Cover with foam to suppress evaporation. Transfer to tank truck or special collector with explosion proof pump for recovery or transportation to waste disposal site.
