First aid, CPR & electrical contact rescue
Where to get First Aid, CPR and AED certified, what tree crews must know, and step by step what to do when someone contacts a power line.
Why tree crews need it
- ANSI Z133 requires workers exposed to electrical hazards to be trained in first aid and CPR.
- OSHA 1910.269 requires trained first aid/CPR people on line-clearance crews: at least 2 for field crews of 2 or more.
- OSHA 1910.151 requires a trained first aid person when no clinic or hospital is near the work.
- Cardiac arrest from electrical shock needs CPR and an AED within minutes. Survival drops about 10% for every minute without it.
Where to get certified
| Provider | Course | How to find a class |
|---|---|---|
| American Red Cross | First Aid/CPR/AED (adult, child, infant), blended or in person | redcross.org/take-a-class — search by ZIP code |
| American Heart Association | Heartsaver First Aid CPR AED; BLS for advanced | cpr.heart.org — Find a Course |
| National Safety Council | First Aid, CPR & AED; workplace classes | nsc.org/safety-training/first-aid |
| ASHI / HSI | Basic First Aid, CPR and AED | hsi.com — find a training center |
| Local options | Fire departments, hospitals, community colleges, county EMS | Call your local fire department or hospital |
| Employer / TCIA | On-site crew classes | Ask your safety lead; TCIA members can book trainers |
Online-only courses usually don't count for OSHA. Pick a blended or in-person class with a hands-on skills test.
What the course covers and how long it lasts
- Typical class: 3–5 hours in person, or online lessons plus a 1–2 hour skills session.
- Typical cost: about $70–$130.
- Certificates last 2 years. Many crews refresh CPR every year.
- Ask for a course that covers severe bleeding and tourniquets, burns, shock and chainsaw cuts.
- Keep your card number in My certificates so you get a renewal reminder.
Someone contacted a power line: what to do
The person may still be energized. Rushing in can kill a second worker.
- 1. STOP. Don't touch the person, the tree, the rope, the truck or anything touching them.
- 2. Call 911 and the utility emergency number. Say "electrical contact, tree worker" and give the address.
- 3. Keep everyone at least 35 ft away from a downed line or energized truck. Shuffle with feet together if the ground may be energized.
- 4. Wait for the utility to confirm the line is dead and grounded. Only qualified line-clearance workers with insulated tools may try to free someone sooner, following utility rules.
- 5. Once it is safe, check breathing. If they aren't breathing normally, start CPR and send for the AED.
- 6. Use the AED as soon as it arrives and follow its prompts.
- 7. Treat burns: cool with clean water and cover loosely. Look for entry and exit wounds — damage inside is often worse than it looks.
- 8. Treat for shock: lay them flat, keep them warm, don't give food or drink.
- 9. Everyone who had an electrical contact goes to the hospital, even if they seem fine. Heart rhythm problems can show up hours later.
Never touch a victim until you know the power is off. One victim is a tragedy; two is a failed rescue.
Aerial rescue near power lines
- Before going up, look for any contact between the victim, tree, rope or bucket and a conductor. If there is any chance, wait for the utility.
- Only a qualified line-clearance arborist may climb or use a bucket inside the minimum approach distance during a rescue.
- Climber in the tree: climb on a separate, safe tie-in, get the victim on your system, then lower them with a friction device.
- Worker in a bucket: use the lower (ground) controls to bring the bucket down — but only after confirming the truck and boom are not energized.
- Get the victim to the ground fast. CPR doesn't work well aloft.
- Practice rescues every year in a safe tree with no lines nearby.
CPR quick steps (adult)
- Check the scene is safe. Tap and shout. Call 911 and send for an AED.
- Push hard and fast in the center of the chest: at least 2 in deep, 100–120 pushes a minute.
- If trained, give 2 rescue breaths after every 30 pushes. If not, keep doing chest pushes only.
- Turn on the AED as soon as it arrives and follow the voice prompts.
- Don't stop until EMS takes over, the person starts breathing, or you can't keep going.
Kit for the truck
- AED, kept charged and checked monthly.
- Trauma kit: tourniquets, pressure bandages, hemostatic gauze.
- Burn dressings and clean water.
- Emergency contacts: 911 address, nearest hospital, utility emergency number, in the job briefing.
Cautions
- This page is not a replacement for a hands-on First Aid/CPR/AED course. Get certified by an approved provider.
- Never approach anyone who may be in contact with electricity until the utility confirms the line is dead.
- Prices and course details vary. Check the provider for current information.
