During which activity is supervision not required according to fumigation protocols?

Supervision is crucial in fumigation processes to ensure safety and compliance with regulations. It is typically required when individuals who are not adequately trained are involved in fumigation activities, since these tasks can be hazardous and require knowledge of proper procedures, equipment handling, and safety protocols.

The option that states supervision is not required relates to activities where oversight might not be necessary for safety or compliance. In this context, activities such as air monitoring or training sessions generally involve specific protocols where supervision ensures that practices align with safety standards and that individuals are prepared for practical aspects of fumigation.

Therefore, when it comes to the fumigation process performed by untrained individuals, the lack of supervision is not permissible due to the inherent risks and complexities involved in safely conducting fumigation. This highlights the essential need for appropriate supervision during fumigation activities to minimize hazards and ensure effective practices.
