The First 60 Seconds of an Arc Response
Immediate, life-saving actions to take when witnessing an arc flash or severe electrical shock.
An arc flash or violent electrical shock unfolds in fractions of a second. The actions taken by bystanders and crew members in the 60 seconds immediately following the blast are the most critical determinants of the victim’s survival.
Step 1: Secure the Scene (Do Not Rush In)
The instinct to grab a fallen coworker is human nature, but it often results in secondary fatalities. You must instantly verify if the victim is still in contact with the energized source. If they are, de-energize the circuit immediately at the local disconnect or upstream breaker. Never try to push or pull a victim with ad-hoc objects.
Step 2: Extinguish Flames
Arc flashes produce temperatures exceeding 35,000°F. If the victim’s FR clothing or underlayers are smoldering, use a fire blanket or initiate the “Stop, Drop, and Roll” method.
Step 3: Activate EMS & Begin CPR
Designate one specific person by name to call 911 (e.g., “John, call 911 and tell them we have an electrical burn victim”). If the victim is unresponsive and the area is confirmed de-energized, begin CPR and deploy an AED immediately.
Preparation is key. Know where the nearest disconnects, fire blankets, and AEDs are located before the shift begins.
