What special hazard do fumigants present for pesticide handlers?

1. High environmental impact

2. Inhalation hazards

3. Low toxicity

4. Permanent skin contact safety

The correct answer is: Inhalation hazards

Fumigants are particularly dangerous due to their properties that can lead to severe inhalation hazards. These substances are designed to penetrate structures or materials, such as soil or grain, to eradicate pests and often exist as gases. When handled improperly or without adequate protective equipment, there is a significant risk that handlers can inhale these toxic gases, which can lead to serious health issues or even fatality. The other choices do not accurately capture the most critical risk associated with fumigants. For instance, while some fumigants can have a high environmental impact, this is not the unique hazard they pose specifically to pesticide handlers. Similarly, low toxicity is misleading because many fumigants are highly toxic, particularly in gaseous forms, thus posing serious threats to individuals in proximity. Permanent skin contact safety might imply a risk of skin absorption, but fumigants are primarily hazardous through inhalation due to their volatile and gaseous nature. Understanding the inhalation hazards is crucial for effective safety protocols and minimizing risks when working with these substances.
