Protective Measures
Emergency treatment: quickly evacuate people from the contaminated area to the safe area, isolate them, and strictly restrict access. Cut off the fire. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and protective clothing. Cut off the source of leakage as much as possible. If it is liquid, prevent it from flowing into restricted Spaces such as sewers and drainage ditches.
Small amount of leakage: rinse with a lot of water, dilute the washing water and put it into the wastewater system.
Large amount of leakage: build dike or dig pit for reception. Pump to the tank or special collector, recycling or transport to the waste treatment site for disposal. If it is solid, collect it in a dry, clean, covered container with a clean shovel. If a large number of leakage, collect recycling or transport to the waste treatment site for disposal.
