EEI TECH EEI Tech Safety Procedures 1 — Questions and Answers
Question 1: What does 'Lockout/Tagout' (LOTO) protect workers from?
- Chemical spills
- Unexpected energization of equipment during maintenance (Correct answer)
- Falling objects
- Electrical overloads
Correct answer: Unexpected energization of equipment during maintenance
LOTO procedures prevent equipment from being accidentally energized while workers perform maintenance.
Question 2: When must a worker apply a personal lock during LOTO?
- Only when a supervisor is absent
- Before beginning any maintenance on energized equipment (Correct answer)
- After completing maintenance
- When working on low-voltage circuits only
Correct answer: Before beginning any maintenance on energized equipment
Each worker must apply their personal lock before beginning maintenance to ensure the equipment cannot be re-energized.
Question 3: What does the acronym PPE stand for in workplace safety?
- Power Plant Equipment
- Personal Protective Equipment (Correct answer)
- Primary Protection Engineering
- Protective Panel Enclosure
Correct answer: Personal Protective Equipment
PPE stands for Personal Protective Equipment, including hard hats, gloves, safety glasses, and arc flash suits.
Question 4: Before working near overhead power lines, a utility worker should:
- Estimate a safe distance by eye
- Verify minimum approach distances per OSHA standards (Correct answer)
- Work quickly to minimize exposure time
- Turn off all personal electronics
Correct answer: Verify minimum approach distances per OSHA standards
OSHA requires workers to observe minimum approach distances from energized overhead lines before any work.
Question 5: An arc flash hazard label shows 'Incident Energy: 12 cal/cm².' This information is used to select:
- The correct fuse size
- Appropriate arc-rated PPE (Correct answer)
- The right wire gauge
- The correct breaker trip setting
Correct answer: Appropriate arc-rated PPE
Incident energy levels determine the arc flash category and the arc-rated PPE required for safe work.
Question 6: What is the correct action when you discover a co-worker receiving an electrical shock?
- Pull the worker away immediately
- De-energize the circuit before touching the victim (Correct answer)
- Apply water to cool the area
- Begin CPR while the circuit is still live
Correct answer: De-energize the circuit before touching the victim
You must de-energize the circuit first to avoid also becoming a victim before assisting the shocked worker.
