First Aid, CPR/AED, and Emergency Response in the Welding Shop

Why First Aid Matters in the Welding Shop

Welding combines high-voltage electricity, intense heat, ultraviolet radiation, and hazardous fumes in one workspace. Injuries can escalate quickly. A co-worker who collapses from cardiac arrest has the best chance of survival if bystander CPR begins within minutes — before an ambulance arrives. Every person in the shop must know how to respond, not just the instructor. The skills in this lesson are also required knowledge for AWS SENSE, NCCER, and any professional welding environment governed by safety regulations.

Adult CPR: Step-by-Step

Recognized First Aid/CPR certification programs (such as those from the American Heart Association or the American Red Cross) follow a consistent sequence for adult cardiac arrest.

1. Scene size-up. Before touching anyone, make sure the scene is safe for you. In the welding shop this means confirming that power is off, no arc is running, and there are no live cables near the victim.

2. Check responsiveness. Tap the person's shoulders firmly and shout. If no response, call — or have someone call — 911 immediately and send a second person to retrieve the AED.

3. Check for breathing. Look for normal breathing for no more than 10 seconds. Occasional gasping is not normal breathing.

4. Begin chest compressions. Place the heel of one hand on the center of the chest (lower half of the sternum), interlock both hands, keep arms straight, and compress hard and fast — at least 2 inches deep at a rate of 100–120 compressions per minute. Allow the chest to fully recoil after each compression.

5. Give rescue breaths (if trained and willing). Deliver 2 breaths after every 30 compressions (30:2 ratio). Untrained bystanders may do compression-only CPR.

6. Continue until the AED arrives, a higher-level responder takes over, or the person shows obvious signs of life.

AED Operation

An Automated External Defibrillator (AED) guides the user with voice prompts. The general sequence is: power on → attach pads as shown on the diagrams → let the AED analyze → ensure no one is touching the victim → deliver shock if advised → resume CPR immediately. Training AED units used in class simulate this process without delivering real current. Know where the AED is mounted in your shop before an emergency occurs.

Electrical Shock

Welding equipment operates at voltages that can cause ventricular fibrillation (an uncoordinated, ineffective heartbeat) and severe internal burns along the current's path through the body.

Do not touch an electrical shock victim until the power source is de-energized. Use the machine's main disconnect or your shop's lockout/tagout procedure. Only then approach, call 911, assess for responsiveness and breathing, and begin CPR if needed. Treat the victim as a potential spinal injury patient — avoid unnecessary movement — and keep them warm while waiting for emergency services.

Thermal Burns

Contact with hot metal, spatter, or a welding arc causes thermal burns. Severity ranges from superficial (reddening) to full-thickness.

• Cool the burn with cool running water for at least 10 minutes. Do not use ice, butter, or any home remedy — these worsen tissue damage.
• Remove jewelry or clothing around the burned area only if it is not stuck to the skin.
• Cover loosely with a sterile, non-stick dressing.
• For any burn larger than about the size of a palm, or any burn on the face, hands, feet, genitals, or over a major joint, call 911.

Eye Injuries: Arc Flash and Spatter

Arc flash (photokeratitis) results from unprotected exposure to ultraviolet light from the welding arc. Spatter can embed in the eye. Both are medical emergencies.

• Do not rub the eye. Rubbing can embed particles deeper or abrade the cornea further.
• Irrigate with the plumbed eyewash station for at least 15 minutes, holding eyelids open.
• Cover both eyes with a sterile pad — covering both reduces movement of the injured eye.
• Seek medical attention even if pain subsides. Arc flash symptoms (gritty sensation, pain, tearing) may be delayed hours after exposure.

Fume Inhalation

Welding fumes contain metal oxides and gases that can cause immediate respiratory distress or long-term lung disease.

• Remove the victim to fresh air immediately. If the space is confined or you cannot safely enter, do not go in without appropriate respiratory equipment — call 911 and let trained rescuers respond.
• Call 911 for any person who is unconscious, confused, having difficulty breathing, or who collapsed.
• Keep the victim calm, still, and warm while waiting for help.
• Monitor breathing. Be ready to perform CPR if the person stops breathing.

Shop Emergency Resources: Know Their Locations

Before any emergency happens, walk your shop and memorize where these are:

• Emergency exits and the primary evacuation route
• Fire extinguisher(s)
• Plumbed eyewash station
• First-aid kit
• AED
• Safety Data Sheet (SDS) binder — provides first-aid and exposure information for every chemical in the shop

You will complete an emergency-resource map from memory during today's lab. If you ever cannot locate one of these items in a new workplace, ask before you start work — not during an emergency.

PPE Reminder

Prevention is always the first line of defense. Proper use of auto-darkening or fixed-shade welding helmets, leather gloves, flame-resistant clothing, and ventilation prevents most of the emergencies described above. First aid begins when prevention has already failed.
