CPA Pesticide Safety & Handling 3

Question 1

Which route of pesticide exposure is most commonly responsible for occupational poisonings?

Accepted Answer

Dermal absorption through the skin

Answer

Dermal (skin) absorption accounts for the majority of pesticide exposures in agricultural workers due to constant skin contact.

Question 2

A pesticide with a high vapor pressure is most likely to present what type of hazard?

Accepted Answer

Elevated inhalation risk due to volatilization

Answer

High vapor pressure means the pesticide readily evaporates, increasing the concentration of toxic vapors in the air.

Question 3

When should an applicator wash hands after handling pesticides?

Accepted Answer

Before eating, drinking, smoking, or using the restroom, and after work

Answer

Hands should be washed before any activity that could transfer pesticide residues to the mouth or face, and always after work.

Question 4

What is the purpose of the Hazard Communication Standard (HazCom) Safety Data Sheet (SDS) for pesticides?

Accepted Answer

To provide detailed health, safety, and emergency response information

Answer

The SDS provides comprehensive health hazard, first aid, firefighting, and spill response information for handlers and emergency responders.

Question 5

Organophosphate and carbamate pesticides cause toxicity primarily by:

Accepted Answer

Inhibiting acetylcholinesterase, causing nerve signal accumulation

Answer

Both organophosphates and carbamates inhibit acetylcholinesterase, preventing the breakdown of acetylcholine and causing overstimulation of nerves.
