Fumigation is a method in which premises are disinfected from pests and microorganisms by introducing gaseous pesticides into their habitat. This method is used to destroy pests and microorganisms in various granaries, grain elevators, mills and feed mills, in various warehouses and even ships carrying grain. Fumigation is effective, since not only the room itself is disinfected, but everything that is in it: containers, various equipment, tools and inventory.
For disinfection, special preparations are used based on the active substance – phosphine. Phosphine destroys pests and microorganisms not only in an adult form, it copes well with eggs, pupae and larvae.
NECESSARY CONDITIONS FOR THE USE OF FUMIGATION
Because of their penetrating power, fumigants should be used in rooms and objects that are well sealed. Special attention is paid to sealing, even small holes and crevices are closed, since phosphine in a gaseous state can escape through cracks in the wall, through the roof, windows, doors.
The duration of the procedure is greatly influenced by the temperature and humidity inside the room, as well as the volume of the room, therefore, it is necessary to first take appropriate measurements. It is recommended to carry out fumigation in warm weather, when the temperature inside the room does not drop below 15 °? during the day.
FUMIGATION STAGES
The fumigation procedure should be carried out only by experienced pest specialist authorities who have specialized equipment and personal protective equipment in their arsenal.
The whole process can be roughly divided into three stages:
- Preparatory: At this stage, they are engaged in sealing the room, cleaning it of finished products and unnecessary equipment.
- Fumigant application: A phosphine-based fumigant is stored in solid or powdery form, when exposed to moisture, a poisonous gas begins to be released, filling the entire room. Depending on the humidity and temperature of the room, the exposure can last up to 10 days.
- Purification or degassing: For complete release from phosphine vapours, it is necessary to thoroughly ventilate the entire room for one to two days. After ventilation, the admission of personnel without personal protective equipment is allowed only after measurements with special indicator means.
