Emergency release treatment
Quickly evacuate personnel from the leaked contaminated area to a safe area, and immediately isolate them for 150m, strictly restricting access.Cut off the source of ignition. It is recommended that emergency responders wear self-contained positive pressure breathing apparatus and protective clothing.Enter the scene from upwind. Cut off the source of leakage as much as possible to prevent entry into restricted spaces such as sewers and flood drains.
Small spills: Absorb or absorb with sand or other non-combustible materials. It can also be scrubbed with an emulsion made of a non-flammable dispersant, diluted and put into the waste water system.
Large spills: Construct dikes or dig pits for containment. Cover with foam to reduce vapor hazards. Transfer it to a tanker or a special collector with an explosion-proof pump, and recycle it or transport it to a waste disposal site for disposal.
