COSS Personal Protective Equipment (PPE) 2 — Questions and Answers
Question 1: ANSI Z87.1 is the standard for which type of PPE?
- Head protection
- Eye and face protection (Correct answer)
- Foot protection
- Hand protection
Correct answer: Eye and face protection
ANSI Z87.1 is the American National Standard for Occupational and Educational Personal Eye and Face Protection Devices.
Question 2: A Safety Data Sheet (SDS) Section 8 is primarily consulted to determine which type of PPE?
- Head protection class
- Appropriate gloves and respiratory protection for chemical exposure (Correct answer)
- High-visibility garment class
- Foot protection rating
Correct answer: Appropriate gloves and respiratory protection for chemical exposure
SDS Section 8 — Exposure Controls/Personal Protection — specifies recommended PPE including gloves, respirators, and eye protection for the specific chemical.
Question 3: What OSHA standard specifically covers respiratory protection requirements in general industry?
- 29 CFR 1910.134 (Correct answer)
- 29 CFR 1910.138
- 29 CFR 1910.132
- 29 CFR 1910.136
Correct answer: 29 CFR 1910.134
29 CFR 1910.134 is OSHA's Respiratory Protection Standard, covering program requirements, fit testing, medical evaluation, and respirator selection.
Question 4: Before an employee can use a tight-fitting respirator, OSHA requires which of the following?
- Only training is required
- A medical evaluation and fit test (Correct answer)
- Only a fit test
- Written supervisor approval
Correct answer: A medical evaluation and fit test
OSHA 29 CFR 1910.134 requires both a medical evaluation to ensure the employee can physically wear a respirator and a fit test to confirm the specific respirator seals properly.
Question 5: Class E hard hats are designed to protect against which specific hazard?
- Extreme temperatures
- Electrical hazards up to 20,000 volts (Correct answer)
- Explosive environments
- Enhanced impact resistance
Correct answer: Electrical hazards up to 20,000 volts
ANSI/ISEA Z89.1 Class E (Electrical) hard hats are tested and rated to protect against electrical hazards up to 20,000 volts.
Question 6: What is the main limitation of the Assigned Protection Factor (APF) when selecting respirators?
- APF only applies to filtering facepieces
- APF assumes proper use, fit, and maintenance — not worst-case protection (Correct answer)
- APF values are set by the manufacturer
- APF is only valid for chemical vapors
Correct answer: APF assumes proper use, fit, and maintenance — not worst-case protection
APF represents the level of protection a properly functioning respirator provides to a properly fitted and trained user under workplace conditions, so real-world protection can be less if fit or use is poor.
