What should a qualified applicator do if there is an equipment malfunction during fumigation?

In the event of an equipment malfunction during fumigation, assessing the situation and implementing corrective actions is crucial for several reasons. First, fumigation involves the use of potentially hazardous chemicals, and a malfunction could lead to ineffective treatment or unsafe conditions for workers and the surrounding environment. By assessing the malfunction, the qualified applicator can determine the severity of the issue and whether any immediate safety measures need to be taken.

Corrective actions may involve troubleshooting the equipment, making necessary repairs, or adjusting the fumigation process to ensure that it can be completed safely and effectively. This proactive approach helps prevent potential harm that could arise from continuing the fumigation without proper equipment functionality.

While documenting the malfunction for future reference is also important, it should be part of the overall response rather than a standalone action. In addition, calling for external help may not be the first step to take, especially if the qualified applicator is trained to resolve the issue on-site. Ignoring the malfunction poses significant risks and is not an acceptable course of action. Thus, assessing and implementing corrective actions is the most responsible and effective response during fumigation operations.
