Take a sandbag and cover it with a tarpaulin. If the floor of the warehouse or the place of fumigation is not guaranteed, cover the bottom of the counter with tarpaulin to limit the loss of medicine. Check the tightness of the tarpaulin, if it is punctured, it must be sealed with tape or kraft paper and glue.

Time to disinfect with tarpaulin: the person performing the disinfection must have an anti-toxic mask to remove the sand snakes and then cover a part of the tarpaulin. After about 4 hours, test the Phosphine gas concentration inside the container. inside the shipment. If the concentration is below the allowable safe threshold, the staff will remove the tarpaulin, collect the drug residue and check the results.

For warehouse disinfection: the fumigation worker uses a knife to cut the paper and open the warehouse. After 4 hours, test the phosphine gas concentration in the warehouse. If the concentration is below the safe threshold, the drug residue will be collected and the results will be accepted.

Industrial dryers can be used to accelerate drug treatment.

Treatment of drug residues: After completion of the sterilization process, the drug residues will be collected and buried under the ground. Particularly for Aluminum phosphide in the residue, there is still 2% that cannot be decomposed, so it is necessary to treat the residue before burying. The drug residue is poured directly into a container containing a concentrated soap solution and then mixed well so that the drug is completely decomposed, the person in charge of handling must wear an anti-poison mask and protective eyewear.
