Which statement is true regarding the application of non-soil fumigants?

The statement that non-soil fumigants require monitoring for safety and effectiveness is correct because monitoring is essential to ensure that fumigants disperse correctly and achieve the desired level of pest control while also protecting human health and the environment. Proper monitoring allows applicators to assess exposure levels and ensure that the concentration of fumigants remains within safe limits during and after application. This process also helps to evaluate the effectiveness of the treatment in controlling targeted pests.

In the context of non-soil fumigation, various factors can influence the performance of the fumigant, such as temperature, humidity, and the type of material being treated. Therefore, continuous assessment during the fumigation process is crucial for achieving satisfactory results and adhering to safety regulations.

In contrast, statements regarding non-soil fumigants that suggest they can be applied without precautions, can be used without permits, or are safe to use without protective equipment overlook the stringent regulations and safety protocols designed to protect applicators and the public from potential hazards associated with these chemicals. Safe application requires adherence to legal and safety standards, including the use of protective gear and obtaining necessary permits.
