Quickly evacuate personnel from the leaked contaminated area to a safe area, isolate them, and strictly restrict access. Cut off the source of ignition. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and fire protection clothing. Cut off sources of leaks as much as possible. Prevent entry into restricted spaces such as sewers and flood drains.
Small spills: Absorb with other inert material. It can also be scrubbed with an emulsion made of a non-flammable dispersant, which is 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.
