Fumigants are chemicals used as pesticides or disinfectants in their gaseous state. They have various uses, including structural fumigation, agricultural sterilization, and medical facility decontamination. Fumigants can be toxic and must be handled by certified professionals with proper safety protocols. They come in different forms and are selected based on the task at hand.
A fumigant is a chemical that is used as a pesticide or disinfectant while in its gaseous state. There are numerous uses for fumigants and these chemicals are manufactured by chemical companies around the world. Fumigants must be used with care, as they can be extremely dangerous, and some are only sold or released to people certified to handle them, to ensure they don’t fall into the hands of someone inexperienced.
One of the more famous uses of fumigants is in structural fumigation, where a structure is stretched to hold gas and filled with gas. As the gas moves through the structure, it kills the parasites inside. The tent can take several days, with additional time to allow the structure to fully air out before people and pets are allowed back inside. This practice is commonly used with insect pests such as termites that cannot be controlled with less drastic measures.
The agricultural industry is a large consumer of fumigants. Fumigants are used to sterilize soil before planting, to treat infested crops, and to treat crop produce that has been infested. Agricultural fumigants can be used in greenhouses, storage facilities and open fields. Fumigants are also sometimes used in medical facility sterilization and equipment decontamination.
Products such as textiles, leather goods, etc. can also be fumigated if they are believed to be contaminated or if they are brought through a containment line. For example, if an area is experiencing an outbreak of a plant disease, materials shipped from that area may be shipped to prevent the spread of the disease.
The biggest concern with fumigants is that they can be toxic to people, nonhuman animals, and plants. Before an area is fumigated, it must be carefully inspected to confirm that no one is inside, and the fumigant must be tightly controlled during the fumigation process to avoid leakage. Operators receive special training on safety protocols and the appropriate clothing to wear while fumigating. They also learn how to ventilate spaces during and after fumigation procedures and how to deal with emergencies that may arise.
A fumigant can come in the form of a powdered or liquid chemical compound that must be reacted with something else to achieve a gaseous state for fumigation, or it can come as a compressed gas or liquid that is pushed through an aerosol to create a gaseous fumigant . Different chemicals are suited to different tasks, with pest control and sanitation professionals having the experience to select the right tool for the job.
