ETC Safety Standards & Regulatory Compliance 2 — Questions and Answers
Question 1: Which OSHA standard specifically governs lockout/tagout procedures for the control of hazardous energy?
- 29 CFR 1910.147 (Correct answer)
- 29 CFR 1910.132
- 29 CFR 1910.303
- 29 CFR 1910.212
Correct answer: 29 CFR 1910.147
29 CFR 1910.147 is OSHA's Control of Hazardous Energy (Lockout/Tagout) standard that establishes minimum performance requirements for controlling hazardous energy.
Question 2: A technician discovers that a piece of equipment does not have an established lockout/tagout procedure. What is the correct first step?
- Notify the supervisor and stop work until a procedure is developed (Correct answer)
- Proceed using general lockout principles without a written procedure
- Tag the equipment out only, since no lockout procedure exists
- Continue work and document the missing procedure afterward
Correct answer: Notify the supervisor and stop work until a procedure is developed
OSHA requires written energy control procedures before servicing equipment; work must stop until a proper procedure is established.
Question 3: Under NFPA 70E, what is the purpose of an arc flash boundary?
- To define the distance within which a person could receive a second-degree burn from an arc flash (Correct answer)
- To mark the maximum distance for wearing rubber gloves
- To identify where Class E fire extinguishers must be placed
- To establish the boundary for ground fault protection zones
Correct answer: To define the distance within which a person could receive a second-degree burn from an arc flash
The arc flash boundary under NFPA 70E is the distance at which a person could receive a second-degree burn (1.2 cal/cm²) if an arc flash occurs.
Question 4: Which agency enforces the Toxic Substances Control Act (TSCA) regarding hazardous chemical use in the workplace?
- EPA (Correct answer)
- OSHA
- NIOSH
- DOT
Correct answer: EPA
The Environmental Protection Agency (EPA) administers and enforces TSCA, which regulates the introduction and use of chemical substances.
Question 5: What does the term 'hierarchy of controls' mean in safety engineering?
- A prioritized sequence for selecting hazard control methods from most to least effective (Correct answer)
- The chain of command for reporting safety violations
- The order in which PPE must be donned
- The regulatory hierarchy from federal to state safety standards
Correct answer: A prioritized sequence for selecting hazard control methods from most to least effective
The hierarchy of controls ranks hazard mitigation strategies from elimination (most effective) down to PPE (least effective).
Question 6: A chemical's Safety Data Sheet (SDS) Section 8 contains which type of information?
- Exposure controls and personal protective equipment (Correct answer)
- Physical and chemical properties
- First aid measures
- Handling and storage guidelines
Correct answer: Exposure controls and personal protective equipment
SDS Section 8, per GHS/HazCom 2012, covers exposure limits, engineering controls, and appropriate PPE for the chemical.
Question 7: Which electrical safety practice requires verifying absence of voltage before touching exposed conductors?
- Test before touch (Correct answer)
- Ground before work
- Tag before test
- Isolate before inspect
Correct answer: Test before touch
The 'test before touch' principle requires using a voltage detector to confirm de-energization before making physical contact with conductors.
