Storage and transportation conditions |
Storage and transportation conditions: Store in a cool, ventilated warehouse. Keep away from fire and heat. It should be stored separately from oxidants, reducing agents, halogens, etc., and should not be mixed. Lightly load and unload during handling to prevent damage to packaging and containers. The tank (tank) used in transportation should have a grounding chain, and a hole partition can be arranged in the tank to reduce the static electricity generated by the shock. It is strictly forbidden to mix and mix with oxidants, reducing agents, halogens, food chemicals, etc. The vehicle exhaust pipe carrying the item must be equipped with a fire-stop device, and it is forbidden to use the mechanical equipment and tools that are prone to sparks. When transporting by road, follow the prescribed route and do not stay in residential areas and densely populated areas. | |||||||||||
|
And leak handling |
Leakage treatment: evacuate personnel from the contaminated area to a safe area, prohibit unrelated personnel from entering the contaminated area and cut off the fire source. It is recommended that emergency personnel wear a poison mask and wear chemical protective clothing. A small amount of leakage: the emulsion is washed with a non-flammable dispersant, and the washing solution is diluted and placed in a waste water system. A large number of leaks: build dikes or digging pits, cover with foam, and reduce steam disasters. Transfer to a dedicated collector with an explosion-proof pump, recycle or transport to a waste disposal site for disposal. | |||||||||||
