What harm does fumigation and exhaust of grain depot have to close residents?

First, the waste gas component of grain depot fumigation is phosphine.

Phosphine is a colorless, highly toxic and flammable gas.

Second, regular operations have little impact on residents.

Stored grain is prone to pests. According to the insecticidal mechanism of aluminum phosphide, phosphine produced after gasification is used to kill insects. Each fumigation time is generally about 10 days. At this time, phosphine has been basically absorbed by pests, with only a small amount of residue. After fumigation, open the plastic film, open the doors, windows and ventilation gates, and adopt natural ventilation and mechanical ventilation to fully disperse the gas and discharge the toxic gas.

Third, there is no danger in discharging waste gas. The key is to avoid accidents when manufacturing!

Prevent accidents caused by improper operation and management during operation. Aluminum phosphide drugs should be kept cool, dry and well ventilated when stored, and must be stored in a sealed manner. Stay away from livestock and poultry, and have someone to raise them. No fireworks sign shall be erected in the drug warehouse.

During storage, if the drug catches fire, do not use water or acidic substances to extinguish the fire, but use carbon dioxide or dry sand to extinguish the fire.

Keep away from children, and do not store and transport with food, beverage, grain, feed and other items. Aluminum phosphide tablets should be handled with care during loading, unloading and transportation to prevent moisture, high temperature or sun exposure.

Fourth, the generated solid waste should be recycled.

The residual aluminum hydroxide and aluminum phosphide after the reaction in the fumigation process belong to waste drugs and HW03 drugs in hazardous waste. If it is not handled properly, it will have a certain impact on the environment and must be recycled.
