✅ Correct Answer: B. Indicate the toxicity level of the product
Explanation:
The signal word (“Caution,” “Warning,” or “Danger”) reflects the acute toxicity to humans and
is legally required. "Danger" indicates the highest toxicity, followed by "Warning" and
"Caution."
2. What PPE is required when a pesticide label states: “Wear chemical-resistant
gloves, long sleeves, and eye protection”?

B. Nitrile gloves, long-sleeved shirt, safety goggles
C. Bare hands, eye protection only
D. Leather gloves, t-shirt, and face shield
✅ Correct Answer: B. Nitrile gloves, long-sleeved shirt, safety goggles
Explanation:
“Chemical-resistant” excludes leather or cotton. Nitrile or neoprene gloves meet the
