Pest Control Aircraft Pilot Practice Test

When must pilots wear the required PPE during an aerial application?

1. Before taking off

2. While making nozzle adjustments

3. After applying the pesticide

4. Only during ground checks

The correct answer is: While making nozzle adjustments

Wearing the required personal protective equipment (PPE) while making nozzle adjustments is essential because this is a critical phase of the aerial application process where the pilot might be exposed to pesticide residues or drift. Nozzle adjustments can lead to direct contact with pesticides, and wearing PPE ensures that pilots are protected from potential health risks associated with exposure to these chemicals. While there's a case for wearing PPE before taking off or during ground checks, these options do not account for the immediate risks associated with pesticide handling. After applying the pesticide, the primary danger has already passed, making it less critical. Thus, the timing of PPE use is crucial, and doing so while making nozzle adjustments specifically addresses the risk of exposure at that moment.
