What is a critical safety measure for applicators during fumigation?

Wearing appropriate personal protective equipment (PPE) is crucial for applicators during fumigation because it serves to protect them from the potentially harmful effects of toxic gases used in the fumigation process. Fumigants can pose significant health risks, including respiratory issues, skin irritation, and other acute or chronic health effects.

By using the correct PPE, which may include respirators, gloves, goggles, and protective clothing, applicators can mitigate exposure to these hazardous chemicals. This safety measure not only ensures the health and safety of the applicators themselves but also contributes to the overall safety of the operation, reducing the risk of unintended exposure to others in the vicinity.

Other options, though they may contribute to safety in various contexts, do not directly address the immediate health risks associated with fumigation. For instance, while working in groups and daylight operations may enhance situational awareness and contribute indirectly to safety, the primary and most direct measure to protect against chemical exposure is the proper use of PPE.
