Safety Trained Supervisor MCQ 2 — Questions and Answers
Question 1: Which OSHA standard addresses Hazard Communication program requirements?
- 29 CFR 1910.134
- 29 CFR 1910.1200 (Correct answer)
- 29 CFR 1926.501
- 29 CFR 1910.147
Correct answer: 29 CFR 1910.1200
29 CFR 1910.1200 is the Hazard Communication Standard requiring employers to inform employees about chemical hazards.
The standard requires written hazard communication programs, Safety Data Sheets, proper labeling, and employee training. It was updated in 2012 to align with the Globally Harmonized System (GHS).
Question 2: What is the permissible noise exposure limit for an 8-hour shift according to OSHA?
- 80 dBA
- 85 dBA
- 90 dBA (Correct answer)
- 95 dBA
Correct answer: 90 dBA
OSHA PEL for noise is 90 dBA for an 8-hour TWA under 29 CFR 1910.95.
The action level triggering hearing conservation programs is 85 dBA. For every 5 dBA increase above 90, permissible time halves. NIOSH recommends a more protective 85 dBA with 3 dB exchange rate.
Question 3: Which would be classified as a restricted work case under OSHA recordkeeping?
- Employee takes a day off for a back strain
- Employee is assigned light duty preventing normal job functions (Correct answer)
- Employee receives first aid and returns to normal work
- Employee is hospitalized overnight
Correct answer: Employee is assigned light duty preventing normal job functions
Restricted work occurs when an employee cannot perform routine job functions due to a work-related injury.
Restricted work cases under 29 CFR 1904 differ from days away (cannot work at all) and first aid (not recordable). Light duty where normal functions cannot be performed must be recorded on the OSHA 300 Log.
Question 4: Which fire extinguisher class is appropriate for electrical equipment fires?
- Class A
- Class B
- Class C (Correct answer)
- Class D
Correct answer: Class C
Class C extinguishers are for fires involving energized electrical equipment, using non-conductive agents.
Class C uses non-conductive agents like CO2 or dry chemical. Once equipment is de-energized, the fire becomes whatever class the burning material falls under. ABC-rated multipurpose extinguishers cover three common classes.
Question 5: What does SDS Section 8 specifically address?
- First-aid measures
- Composition and ingredients
- Exposure controls and personal protection (Correct answer)
- Physical and chemical properties
Correct answer: Exposure controls and personal protection
Section 8 covers exposure controls and personal protection including OELs, engineering controls, and PPE.
Under the GHS 16-section format, Section 8 provides applicable exposure limits, recommended engineering controls, and required PPE. This section directly informs control and PPE selection for hazardous chemicals.
Question 6: Under OSHA Lockout/Tagout standard, what must be performed at least annually?
- Replacement of all lockout devices
- A periodic inspection of energy control procedures (Correct answer)
- Retraining of all authorized employees
- Testing of all emergency shutdown systems
Correct answer: A periodic inspection of energy control procedures
OSHA requires energy control procedures be inspected annually to ensure adequacy.
The inspection must be performed by an authorized employee other than the one using the procedure, must review responsibilities, and include a compliance demonstration. This catches deviations as equipment and processes change.
