Reasonable ventilation, accelerate the spread. Spray water dilution, dissolution. Build embankments or dig pits to contain a large amount of wastewater generated. If possible, send residual or leaked air to the washing tower or a fume hood connected to the tower with an exhaust fan. Leaking air containers should be properly disposed of, repaired, inspected and then used.
2. ** The containment and removal method of leaking chemicals and the disposal materials used **: Construct a dike or dig a pit to contain a large amount of wastewater generated. Adsorb or absorb with sand or other non-combustible materials. It can also be rinsed with a large amount of water, and the washing water is diluted and placed into the wastewater system.
