CPR Respiratory & PPE Programs 2 — Questions and Answers
Question 1: Under OSHA's Respiratory Protection Standard (29 CFR 1910.134), who must review and approve a written respiratory protection program?
- Any trained employee
- A suitably trained program administrator (Correct answer)
- The local fire marshal
- NIOSH directly
Correct answer: A suitably trained program administrator
OSHA requires the program to be administered by a suitably trained program administrator who is knowledgeable about respiratory hazards and respirator use.
Question 2: Which respirator class provides the highest level of protection against airborne contaminants in restoration environments?
- Half-face air-purifying respirator
- N95 filtering facepiece
- Supplied-air respirator (SCBA) in pressure-demand mode (Correct answer)
- Powered air-purifying respirator (PAPR) with HEPA filter
Correct answer: Supplied-air respirator (SCBA) in pressure-demand mode
Pressure-demand SCBA provides the highest assigned protection factor (APF of 10,000) and is used in immediately dangerous to life or health (IDLH) atmospheres.
Question 3: During mold remediation, a worker enters a category-3 contamination area. What minimum respiratory protection is typically required?
- N95 disposable respirator
- Half-face respirator with P100 filters
- Full-face respirator with combination OV/P100 cartridges (Correct answer)
- No respirator required if work is under 30 minutes
Correct answer: Full-face respirator with combination OV/P100 cartridges
Extensive mold contamination (Category 3) requires a full-face respirator with combination organic vapor and P100 particulate filters to protect against both spores and VOCs.
Question 4: Which NIOSH filter designation blocks at least 99.97% of airborne particles and is oil-proof?
- N99
- R100
- P100 (Correct answer)
- N100
Correct answer: P100
P100 filters are rated to filter at least 99.97% of particles and are resistant to oil-based aerosols, making them suitable for environments with both particulates and oil mists.
Question 5: A respirator medical evaluation must be provided to employees before fit testing. Which form is OSHA-approved for this evaluation?
- OSHA Form 300
- OSHA Appendix C Questionnaire (Correct answer)
- NIOSH Form B-Reader
- CDC Form 50.34
Correct answer: OSHA Appendix C Questionnaire
OSHA Appendix C to 1910.134 is the mandatory medical evaluation questionnaire that a licensed healthcare professional must review before clearing an employee for respirator use.
Question 6: What is the correct sequence for doffing (removing) PPE to minimize cross-contamination?
- Gloves → respirator → goggles → suit (Correct answer)
- Suit → gloves → goggles → respirator
- Respirator → gloves → goggles → suit
- Goggles → suit → gloves → respirator
Correct answer: Gloves → respirator → goggles → suit
Gloves are removed first because they are the most contaminated item, followed by the respirator last since the face must be protected until other contaminated gear is off.
Question 7: Which type of fit test uses a saccharin or Bitrex solution to evaluate respirator seal on the wearer?
- Quantitative fit test (QNFT)
- Qualitative fit test (QLFT) (Correct answer)
- User seal check
- Assigned protection factor test
Correct answer: Qualitative fit test (QLFT)
Qualitative fit testing (QLFT) uses challenge agents like saccharin or Bitrex that the wearer can taste or smell if the seal is inadequate, relying on a pass/fail subjective response.
