What points should be paid attention to when fumigating granaries with pesticides?

The air in the upper part of the grain layer enters the circulating fan through the circulating pipeline, and the fumigation gas source is connected to the outlet of the fan, and then sent to the above-ground cage air duct through the circulating pipeline, which spreads upward to the whole grain layer, and is repeatedly circulated according to this method. After fumigation or when the warehouse needs to be opened, turn on the ventilator and axial fan to exhaust the waste gas through air circulation. The fumigant is AlP. After AlP is gasified, it is fumigated with mixed gas (blast) of PH3 and CO2, and the fumigation equipment is fumigation machine outside the warehouse. The circulating pipeline is equipped with a PH3 concentration detection port, which can replenish fumigant in time to maintain the effective concentration during fumigation and ensure the insecticidal effect.

The gasification reaction formula of fumigant is AlP+H2O (moisture in air) PH3+Al (OH) 3.

Antivirus measures

During fumigation, the danger signs in this area should be marked and a safe distance should be drawn. All fumigation personnel carrying out ventilation operations must wear protective clothing; All granaries and fumigation pipes should have good sealing performance. At the same time, we must strictly abide by the relevant rules and regulations of the grain industry and the enterprise management system, and operate and use fumigants.

Equipped with corresponding toxic gas detection equipment to detect the concentration of harmful gases in the workshop of the reservoir area, and regularly carry out physical health examination for employees; In case of employee poisoning, it must be handled properly in accordance with relevant measures immediately, or sent to a nearby large hospital for treatment. In addition, it is also essential to strengthen the anti-virus education of employees.
