Commodity Fumigation License Practice Exam

What is the maximum allowable fumigant level within an enclosure after aeration, according to safety regulations?

1. 50 parts per million

2. 25 parts per million

3. 10 parts per million

4. 5 parts per million

The correct answer is: 5 parts per million

The maximum allowable fumigant level within an enclosure after aeration is set at 5 parts per million (ppm). This limit is established to ensure the safety of individuals who may enter the area after fumigation. Maintaining a low concentration of fumigant is crucial to reduce exposure risks to humans and the environment, as even small amounts can be hazardous. Regulatory standards and safety protocols require thorough aeration following fumigation to dissipate any residual chemicals. The 5 ppm threshold is designed to establish a safe working environment, providing substantial protection against potential toxic effects associated with higher levels of fumigants. It reflects both safety considerations and the need to minimize any lingering risk during post-fumigation activities.
