Which safety measure is critical during the fumigation process?

Wearing protective gear, including masks, is critical during the fumigation process because it helps protect the applicator and others in the vicinity from exposure to hazardous gases and chemicals used in fumigants. Fumigation often involves substances that can be toxic, and appropriate protective equipment, such as gloves, goggles, and masks, is essential to minimize inhalation and skin contact with these potential hazards. This measure is vital not only for the safety of the applicator but also for ensuring the safety of any nearby individuals who might be affected by the fumes.

In contrast, allowing free movement of people in the area during fumigation poses significant risks, as uninformed individuals may inadvertently expose themselves to toxic gases. Conducting fumigation without any equipment would disregard the necessary precautions and safety protocols that safeguard human health. While using fans to circulate air can help disperse gases after fumigation, it is not a safety measure employed during the process itself and may instead help spread fumigant vapors if used prematurely. Thus, the focus on wearing protective gear directly addresses the critical aspects of safety during fumigation.
