ESC Emergency Response & Incident Management 2 — Questions and Answers
Question 1: When an electrical fire breaks out in a panel room, what is the FIRST action a worker should take?
- De-energize the circuit before calling for help
- Call 911 immediately without touching any equipment
- De-energize the source if safely possible, then activate the alarm and evacuate (Correct answer)
- Use a CO2 extinguisher on the panel immediately
Correct answer: De-energize the source if safely possible, then activate the alarm and evacuate
NFPA 70E requires that de-energization be attempted only when it can be done safely; if not, evacuate and activate alarms first.
Question 2: Which fire extinguisher class is rated for energized electrical equipment fires?
- Class A
- Class B
- Class C (Correct answer)
- Class D
Correct answer: Class C
Class C extinguishers use non-conductive agents (CO2 or dry chemical) specifically rated for energized electrical equipment fires.
Question 3: An arc flash incident has occurred and a worker is on fire. What is the correct immediate response?
- Pour water over the worker immediately
- Have the worker stop, drop, and roll; then call emergency services (Correct answer)
- Remove all clothing before applying first aid
- Apply a conductive blanket to smother the flames
Correct answer: Have the worker stop, drop, and roll; then call emergency services
Stop, drop, and roll is the immediate response to clothing fires, followed by activating EMS and providing burn first aid.
Question 4: What information must be included in an electrical incident report per OSHA 29 CFR 1904?
- Only the worker's name and date
- Date, time, location, description of incident, injured party, and root cause (Correct answer)
- A verbal summary provided to the supervisor within 24 hours
- Only recordable incidents resulting in lost workdays
Correct answer: Date, time, location, description of incident, injured party, and root cause
OSHA 29 CFR 1904 requires written records including date, time, location, event description, affected employees, and root cause analysis.
Question 5: A co-worker is in contact with an energized conductor and cannot release their grip. What should a rescuer do FIRST?
- Grab the victim and pull them away forcefully
- De-energize the circuit at the nearest disconnect (Correct answer)
- Call for help while waiting for the victim to free themselves
- Apply water to cool the contact point
Correct answer: De-energize the circuit at the nearest disconnect
The rescuer must de-energize the circuit before making contact with the victim to avoid becoming a second victim.
Question 6: Which document provides the step-by-step procedures workers must follow during an electrical emergency at a facility?
- The equipment nameplate
- The Emergency Action Plan (EAP) (Correct answer)
- The Arc Flash Hazard Analysis report
- The NFPA 70E standard itself
Correct answer: The Emergency Action Plan (EAP)
OSHA 29 CFR 1910.38 requires facilities to maintain an Emergency Action Plan (EAP) that defines evacuation routes, alarm procedures, and worker responsibilities.
Question 7: How long does OSHA require employers to retain records of work-related fatalities?
- 1 year
- 3 years
- 5 years (Correct answer)
- 10 years
Correct answer: 5 years
OSHA 29 CFR 1904.33 requires that OSHA 300 logs, 300A summaries, and 301 incident reports be retained for five years.
