CPA Personal Protective Equipment (PPE) 2 — Questions and Answers
Question 1: Which type of glove material offers the best protection when handling organophosphate pesticides?
- Cotton gloves
- Nitrile gloves (Correct answer)
- Latex gloves
- Leather gloves
Correct answer: Nitrile gloves
Nitrile gloves provide superior chemical resistance to organophosphates compared to cotton, latex, or leather.
Question 2: When should a pesticide applicator replace chemical-resistant gloves during a workday?
- Only at the end of the workday
- Only when they are visibly torn
- If pesticide contacts the outside surface and the label requires it (Correct answer)
- Gloves never need to be replaced during a workday
Correct answer: If pesticide contacts the outside surface and the label requires it
Gloves should be replaced if the pesticide label specifies replacement upon contamination or if gloves show signs of degradation.
Question 3: What does 'chemical-resistant' mean when referring to PPE materials?
- The material will never allow any chemical to pass through
- The material slows the rate at which a chemical penetrates it (Correct answer)
- The material is made from natural rubber only
- The material is waterproof but not chemical-proof
Correct answer: The material slows the rate at which a chemical penetrates it
Chemical-resistant means the material significantly slows penetration of chemicals, but no material provides absolute infinite protection.
Question 4: A respirator fit test is performed to ensure which of the following?
- The respirator filter is the correct NIOSH rating
- The facepiece creates an adequate seal with the wearer's face (Correct answer)
- The cartridge has not expired
- The respirator meets EPA minimum standards
Correct answer: The facepiece creates an adequate seal with the wearer's face
A fit test verifies that the respirator facepiece forms a proper seal against the wearer's face to prevent unfiltered air from bypassing the filter.
Question 5: Which eye protection device provides the greatest coverage against pesticide splash?
- Safety glasses with side shields
- Chemical splash goggles (Correct answer)
- Standard prescription eyeglasses
- Tinted UV-protective sunglasses
Correct answer: Chemical splash goggles
Chemical splash goggles seal around the eye area, preventing liquid from reaching the eyes from any direction.
Question 6: What is the purpose of a chemical-resistant apron when applying pesticides?
- To replace the need for chemical-resistant coveralls
- To provide additional protection to the front of the body when mixing or loading (Correct answer)
- To protect from UV radiation during outdoor applications
- To serve as the primary form of skin protection required by all labels
Correct answer: To provide additional protection to the front of the body when mixing or loading
A chemical-resistant apron adds a protective layer over the front torso and legs during mixing and loading, which carries the highest splash risk.
Question 7: When working in hot conditions, an applicator wants to reduce heat stress while maintaining PPE compliance. What is the BEST approach?
- Remove gloves periodically to allow skin to breathe
- Take scheduled rest breaks in shaded or cool areas while keeping PPE on (Correct answer)
- Switch to lighter cotton coveralls instead of chemical-resistant ones
- Apply pesticides only in the early morning and remove PPE after noon
Correct answer: Take scheduled rest breaks in shaded or cool areas while keeping PPE on
Scheduled rest breaks in cool areas manage heat stress without compromising required PPE protection.
