๐ CALL 911
โก Electric shock โ victim still in contact Critical
If a person is still in contact with a live source, do NOT touch them โ you'll become the second victim.
- Do not touch the victim while they are in contact with the electrical source
- De-energize the source first โ open the disconnect, breaker, or plug. If you don't know which one, kill the main
- If de-energizing is impossible, use a non-conductive object (dry wood pole, dry rope, dry rubber mat) to separate victim from the source โ only if you're 100% sure the item is dry and non-conductive
- Call 911 immediately. All electrical shock victims need medical evaluation โ even if they feel fine, cardiac arrhythmia can develop hours later
- Check breathing + pulse. If absent, start CPR (see below). Use an AED if available
- Treat any visible burns as electrical burns (see next section)
- Keep victim warm and lying down until EMS arrives. Do NOT let them "walk it off"
Delayed danger: Anyone who took a shock through their body (hand-to-hand, hand-to-foot) needs a hospital ECG. Cardiac rhythm can go abnormal 6โ24 hours after the event, even from a low-voltage shock.
๐ฅ Electrical burn Priority
- Ensure the scene is safe โ source de-energized before you touch the victim
- Call 911 for any electrical burn โ the visible wound is usually the small part. Current travels through the body and can cause deep-tissue damage that isn't visible
- Do NOT apply ice, butter, ointments, or wet dressings. Cover with a dry sterile cloth or clean dry sheet
- Do NOT remove clothing that's stuck to the burn
- Look for entry AND exit wounds โ current enters at one point and exits at another. Both need treatment
- Keep the victim warm โ burn victims lose body heat fast
- If conscious, small sips of water are OK unless they feel nauseous. Do NOT give anything by mouth if the burn is severe or they're going into shock
๐ฅ Arc flash injury Critical
Arc flash victims can have burns from radiant heat, blast trauma from the pressure wave, molten copper embedded in skin, retinal burns from UV light, and hearing loss โ all at once.
- Get away from the arcing equipment โ de-energize if you can safely reach a remote disconnect. Do not open the same panel that just flashed
- Call 911. Report "arc flash โ burns, possible blast trauma"
- If clothing is on fire: stop, drop, roll or smother with a fire blanket. Never use water on live equipment
- Cool severe burns with room-temperature water (NOT ice) for 10โ15 minutes if the source is confirmed dead
- Cover eyes with a loose sterile dressing โ even brief arc-UV exposure can cause "welder's flash" that develops 6โ12 hours later
- Monitor for shock: pale, cold, clammy skin, rapid weak pulse. Keep victim lying down with legs elevated (unless spinal injury suspected)
- Do NOT let victim refuse hospital transport. Blast injuries to the ears, lungs, and internal organs can appear normal for hours before decompensating
โค๏ธ CPR (adult) + AED Critical
- Confirm scene is safe โ no live electrical hazard
- Check responsiveness. Shout "Are you OK?" โ tap shoulder. If no response, call 911 immediately (put on speakerphone)
- Check for breathing + pulse for no more than 10 seconds
- If no breathing or no pulse: begin chest compressions โ center of chest, 2 inches deep, 100โ120/min ("Stayin' Alive" tempo)
- 30 compressions : 2 breaths if trained in rescue breathing. Otherwise: hands-only CPR โ continuous compressions, no breaths
- As soon as an AED arrives: turn it on, follow the voice prompts. It will tell you when to stop compressions and stand clear. Shock if advised, then resume CPR immediately
- Continue CPR until EMS arrives, victim revives, or you're physically unable to continue
AED locations: Most schools, gyms, malls, offices, and industrial sites now have AEDs mounted near the main entrance or first-aid station. Learn where yours are BEFORE you need one.
๐ช Fall from elevation Priority
- Do NOT move the victim unless they're in immediate danger (fire, live electrical). Movement can worsen a spinal injury
- Call 911. Report the height of the fall and what they landed on
- Keep victim still, head and neck aligned with the body. Talk to them, keep them awake
- If they were suspended in a fall-arrest harness for more than 5โ10 minutes: suspension trauma is a risk โ blood pools in the legs. Do NOT lay them fully flat immediately if they've been hanging โ keep them in a semi-seated (W) position for 30โ40 minutes while EMS handles the transition
- Look for hidden injuries: broken ribs (breathing hard/painful), internal bleeding (pale/nauseous), head injury (confused, unequal pupils)
๐ช Confined-space rescue Critical
60% of confined-space fatalities are would-be rescuers. Do NOT enter the space to retrieve someone. Ever. Without proper training, gas monitoring, and a permit-required entry rig, you become the second body.
- Do NOT enter the space
- Call 911 immediately โ report "confined-space rescue, victim inside, atmosphere unknown"
- Ventilate if you can safely reach a fan or open all access points from outside
- If a retrieval line/harness is already attached to the victim, use it โ from OUTSIDE the space, with two people minimum on the line
- Do not enter until a trained confined-space rescue team arrives with breathing apparatus and monitoring equipment
๐ What to tell 911 Reference
- Location โ exact address, closest cross-street, building, floor, room. If on a jobsite: gate number, closest crane/landmark
- What happened โ "electrical shock", "arc flash", "burn", "fall from X feet"
- How many victims, ages if known, conscious or not, breathing or not
- Hazards still present โ "live electrical", "fire", "confined space", "elevated location"
- What you're doing โ CPR started, AED applied, victim moved, etc.
- Your name and callback number
- Stay on the line until the dispatcher tells you to hang up. Guide EMS to the exact location when they arrive โ meet them at the main gate if possible

Utility emergency (electric)
Downed wires, transformer fire โ call your local utility's 24h emergency line (not 911 unless there's injury)
Utility emergency (gas)
Smell of gas โ evacuate first, then call utility from a safe distance. Do NOT operate any switch or start a vehicle in the area
โ Reference material โ not a substitute for training. Every worker should hold current first aid + CPR certification (Red Cross, St. John Ambulance, or equivalent). Your employer's site-specific emergency response plan overrides any generic guidance here. When in doubt, call 911 first and ask questions later.
