CPA Pesticide Safety & Handling 5

Question 1

Which practice BEST reduces the risk of pesticide drift during application?

Accepted Answer

Applying during calm conditions with low wind speeds using larger droplet sizes

Answer

Low wind conditions and larger droplet sizes reduce the amount of spray that becomes airborne and moves off-target.

Question 2

Which of the following is a symptom consistent with acute organophosphate pesticide poisoning?

Accepted Answer

Excessive salivation, pinpoint pupils, and muscle twitching

Answer

Organophosphate poisoning causes cholinergic symptoms including excessive secretions, miosis (pinpoint pupils), and muscle fasciculations.

Question 3

A pesticide label instructs users to wear 'chemical-resistant gloves.' Which material is generally LEAST appropriate for most pesticide applications?

Accepted Answer

Natural rubber latex (thin surgical gloves)

Answer

Thin latex surgical gloves provide minimal chemical resistance and can degrade quickly, allowing pesticides to penetrate.

Question 4

If a pesticide is accidently swallowed, what should typically be done FIRST according to label first aid instructions?

Accepted Answer

Call Poison Control (1-800-222-1222) or a physician and follow their instructions

Answer

Calling Poison Control immediately provides expert guidance, since inducing vomiting may be harmful for some pesticide ingestions.

Question 5

The 'preharvest interval' (PHI) on a pesticide label tells the applicator:

Accepted Answer

The minimum days between the last application and harvest

Answer

The PHI is the minimum number of days required between the last pesticide application and crop harvest to ensure residues are at safe levels.
