Electrician Safety and OSHA Requirements 1 — Questions and Answers
Question 1: What OSHA standard covers electrical safety requirements for general industry?
- 29 CFR 1910.132
- 29 CFR 1910.269
- 29 CFR 1910.303 (Correct answer)
- 29 CFR 1926.400
Correct answer: 29 CFR 1910.303
OSHA 29 CFR 1910.303 through 1910.399 covers electrical safety standards for general industry workplaces.
Question 2: What is the purpose of Lockout/Tagout (LOTO) procedures?
- To secure tools at the end of the workday
- To prevent accidental energization of equipment during maintenance (Correct answer)
- To lock electrical panels to prevent unauthorized access
- To tag circuits that are overloaded
Correct answer: To prevent accidental energization of equipment during maintenance
LOTO procedures ensure that hazardous energy sources are isolated and locked out before workers perform maintenance or servicing.
Question 3: What is the minimum approach distance for unqualified workers near exposed energized conductors at 120-240V?
- Any distance with rubber gloves
- 3 feet
- 10 feet
- They must not approach — area must be guarded (Correct answer)
Correct answer: They must not approach — area must be guarded
Unqualified workers must not work on or near exposed energized conductors; the area must be guarded or barricaded to prevent their approach.
Question 4: What does PPE stand for in electrical safety?
- Personal Protection Equipment
- Personal Protective Equipment (Correct answer)
- Powered Protection Equipment
- Primary Protective Enclosure
Correct answer: Personal Protective Equipment
PPE stands for Personal Protective Equipment, which includes items like rubber gloves, face shields, and arc flash suits.
Question 5: What is an arc flash hazard?
- A hazard from touching a live wire with bare hands
- A sudden release of energy caused by an electrical fault that produces extreme heat and blast pressure (Correct answer)
- A hazard from static electricity discharge
- Overheating of a circuit due to sustained overload
Correct answer: A sudden release of energy caused by an electrical fault that produces extreme heat and blast pressure
An arc flash is a dangerous electrical explosion that releases intense heat (up to 35,000°F), light, pressure, and molten metal.
Question 6: Before working on electrical equipment, what must a qualified electrician do first?
- Put on rubber-soled shoes
- Verify the circuit is de-energized using a proper voltage tester (Correct answer)
- Notify the utility company
- Turn off all lights in the area
Correct answer: Verify the circuit is de-energized using a proper voltage tester
NFPA 70E and OSHA require verification of de-energized state using an appropriate voltage-testing device before performing electrical work.
