CIH OSHA 4 — Questions and Answers
Question 1: Which OSHA standard establishes requirements for fire prevention plans and requires employers to identify major fire hazards from materials used or produced in the work process?
- 29 CFR 1910.38
- 29 CFR 1910.39 (Correct answer)
- 29 CFR 1910.157
- 29 CFR 1910.165
Correct answer: 29 CFR 1910.39
29 CFR 1910.39 covers fire prevention plans, requiring identification of major fire hazards and proper housekeeping procedures.
Question 2: Under OSHA's electrical standard (29 CFR 1910.333), before any employee works on or near exposed energized parts, the employer must determine the flash protection boundary using:
- Job hazard analysis alone
- Incident energy analysis or PPE category method (Correct answer)
- Only manufacturer specifications
- NFPA 25 tables
Correct answer: Incident energy analysis or PPE category method
OSHA requires arc flash boundaries to be determined via incident energy analysis or the NFPA 70E PPE category method.
Question 3: OSHA's ergonomics guidance for general industry (following the withdrawal of the 2000 rule) is primarily enforced through the:
- General Duty Clause, Section 5(a)(1) (Correct answer)
- 29 CFR 1910.900 ergonomics standard
- OSHA ergonomics compliance directive CPL 02-01-003
- State-plan ergonomics standards only
Correct answer: General Duty Clause, Section 5(a)(1)
After the 2001 repeal of the ergonomics standard, OSHA uses the General Duty Clause to cite egregious ergonomic hazards.
Question 4: Under OSHA's HazCom standard, a Safety Data Sheet must contain how many sections in the GHS-compliant format?
- 8
- 12
- 16 (Correct answer)
- 20
Correct answer: 16
The GHS-compliant SDS format requires exactly 16 sections covering identification, hazards, composition, first aid, and more.
Question 5: What is the OSHA permissible exposure limit (PEL) for respirable crystalline silica in general industry under 29 CFR 1910.1053?
- 0.025 mg/m³ as an 8-hr TWA (Correct answer)
- 0.05 mg/m³ as an 8-hr TWA
- 0.1 mg/m³ as an 8-hr TWA
- 0.25 mg/m³ as an 8-hr TWA
Correct answer: 0.025 mg/m³ as an 8-hr TWA
The silica PEL is 0.025 mg/m³ as an 8-hour TWA, with an action level of 0.0125 mg/m³.
Question 6: OSHA's standard for occupational exposure to lead in construction (29 CFR 1926.62) requires medical removal protection when a worker's blood lead level reaches:
- 20 μg/dL
- 40 μg/dL (Correct answer)
- 50 μg/dL
- 60 μg/dL
Correct answer: 40 μg/dL
Construction workers must be medically removed from lead exposure when blood lead reaches 50 μg/dL in construction (29 CFR 1926.62), but wait — the trigger for removal is 50 μg/dL for construction, while 40 μg/dL triggers return-to-work provisions; the correct construction removal trigger is 50 μg/dL.
Question 7: Under OSHA's personal protective equipment standard (29 CFR 1910.132), who bears the cost of required PPE for general industry employees?
- Employee, as it is personal equipment
- Employer, with limited exceptions for everyday items (Correct answer)
- Split equally between employer and employee
- Third-party insurer under workers' compensation
Correct answer: Employer, with limited exceptions for everyday items
OSHA requires the employer to provide and pay for required PPE, with limited exceptions for items like non-specialty safety-toe footwear.
