Who must supervise all people involved in the fumigation process?

The supervision of all personnel involved in the fumigation process must be carried out by the certified applicator in charge. This is fundamental because the certified applicator has the necessary qualifications, training, and understanding of both the fumigation process and the associated safety regulations. Their role ensures that all fumigation activities are conducted in compliance with legal and safety standards, thereby minimizing risks to personnel, the public, and the environment.

The certified applicator in charge is responsible for the planning and execution of the fumigation, including making critical decisions about the application process, monitoring conditions, and ensuring that all safety protocols are followed. This level of oversight is crucial because fumigants can be hazardous materials, requiring knowledgeable supervision to manage the risks effectively.

In contrast, while a certified trainer or an experienced worker may have valuable knowledge and skills, they do not hold the same level of responsibility and authority that a certified applicator has. This role specifically mandates oversight that aligns with regulatory requirements, ensuring the safety and effectiveness of the fumigation operation.
