CPA - Certified Pesticide Applicator Personal Protective Equipment (PPE) Questions and Answers 1 — Questions and Answers
Question 1: An applicator is preparing to mix and load a pesticide with the signal word 'DANGER' on the label. The label instructions for PPE have been worn off and are unreadable. What is the MINIMUM PPE the applicator should wear?
- A long-sleeved shirt, long pants, shoes, and socks.
- Chemical-resistant gloves, coveralls over a long-sleeved shirt and long pants, socks, and chemical-resistant footwear.
- A long-sleeved shirt, long pants, waterproof gloves, shoes, socks, and protective eyewear. (Correct answer)
- Just a respirator, as inhalation is the primary concern with highly toxic pesticides.
Correct answer: A long-sleeved shirt, long pants, waterproof gloves, shoes, socks, and protective eyewear.
When a pesticide label does not specify PPE, applicators should still wear at a minimum: a long-sleeved shirt, long pants, chemical-resistant gloves, closed-toe shoes with socks, and protective eyewear, especially when handling concentrates. Given the high toxicity indicated by the 'DANGER' signal word, this level of protection is a crucial baseline.
Question 2: After finishing a pesticide application, what is the correct first step for removing your Personal Protective Equipment (PPE)?
- Remove your respirator first to breathe fresh air.
- Take off your boots and coveralls immediately.
- Wash the outside of your gloves with detergent and water while still wearing them. (Correct answer)
- Remove your safety glasses and rinse them.
Correct answer: Wash the outside of your gloves with detergent and water while still wearing them.
The proper procedure for removing PPE is to first wash the outside of your gloves with detergent and water. This prevents you from contaminating your hands and other surfaces as you remove the rest of your gear. After washing the gloves, you can proceed to remove other items, washing the gloves again after everything else is off.
Question 3: Which of the following is the proper procedure for laundering reusable, non-disposable coveralls that have been contaminated with pesticides?
- Wash them with the regular family laundry to save water and detergent.
- Use a short, cold water cycle with minimal detergent.
- Store them for several days to allow the pesticide to break down before washing.
- Wash them separately from other clothing using hot water, a long wash cycle, and run an empty cycle afterward to clean the machine. (Correct answer)
Correct answer: Wash them separately from other clothing using hot water, a long wash cycle, and run an empty cycle afterward to clean the machine.
Contaminated work clothes and PPE should always be washed separately from family laundry. Use hot water, the highest water level, and a long wash cycle with a heavy-duty detergent. After washing the contaminated items, run the washing machine through an additional empty cycle with detergent and hot water to decontaminate it.
Question 4: A pesticide label requires the use of a respirator with a specific organic vapor (OV) cartridge. In the absence of an end-of-service-life indicator (ESLI) or specific manufacturer instructions, when must the cartridge be replaced?
- When you can smell or taste the pesticide.
- After a maximum of 40 hours of cumulative use.
- At the end of each day's work period. (Correct answer)
- Only when breathing becomes difficult.
Correct answer: At the end of each day's work period.
For gas- and vapor-removing respirator cartridges, if there are no other instructions from the manufacturer or on the label, they must be replaced at the end of each day's work period. Relying on odor, taste, or irritation is not a reliable method as the cartridge may be exhausted before a contaminant is detected.
Question 5: While tank-mixing two different pesticides, Applicator A notes that Pesticide #1 requires a long-sleeve shirt, pants, and waterproof gloves. Pesticide #2 requires coveralls over a shirt and pants, chemical-resistant gloves, and protective eyewear. What is the legally required minimum PPE for Applicator A?
- The PPE listed on Pesticide #1's label.
- A combination of the least restrictive items from both labels.
- Coveralls, a shirt and pants, chemical-resistant gloves, and protective eyewear. (Correct answer)
- The applicator can choose which label to follow.
Correct answer: Coveralls, a shirt and pants, chemical-resistant gloves, and protective eyewear.
When mixing multiple pesticides, the applicator must always follow the most restrictive PPE requirements listed on any of the product labels. In this scenario, Pesticide #2 has the more stringent requirements (coveralls, chemical-resistant gloves, eyewear), which must be followed to ensure adequate protection.
Question 6: Which type of footwear is generally unsuitable for pesticide handling and application, even if not explicitly prohibited by the label?
- Unlined rubber boots.
- Chemical-resistant shoe covers.
- Leather boots. (Correct answer)
- Nitrile or PVC boots.
Correct answer: Leather boots.
Leather is an absorbent material that can trap pesticides, leading to prolonged skin exposure. Once contaminated, it is very difficult or impossible to decontaminate. Therefore, leather boots should be avoided. Chemical-resistant materials like rubber, nitrile, or PVC are recommended.
