Electrical shock is a medical emergency that requires immediate action. Knowing what to do — and what not to do — in the seconds after someone receives an electrical shock can be the difference between life and death.

⚡ Key Takeaways
- Call 911 immediately for any electrical shock — even if the person seems okay
- NEVER touch a person who is still in contact with the electrical source
- Shut off power at the breaker before approaching if the source is household current
- Electrical injuries are often more severe internally than they appear externally
- Even a “minor” shock can cause delayed cardiac arrhythmias — always seek medical evaluation
Immediate Steps After Electrical Shock
Step 1: Do NOT Touch the Person If Still in Contact
If the victim is still touching the electrical source, do not grab them — you will become a second victim. You must disconnect the power source first.
Step 2: Disconnect the Power Source
If it’s a household circuit: go to the electrical panel and switch off the circuit breaker or the main breaker. If you cannot reach the panel, use a non-conductive object (dry wood, plastic) to push the source away from the person. Never use metal or anything wet.
Step 3: Call 911
Call 911 immediately. Even if the person seems conscious and uninjured, electrical shock requires emergency medical evaluation. Electrical current can cause internal injuries, burns, and delayed cardiac arrhythmias that aren’t visible externally.
Step 4: Do Not Move the Person Unless Necessary
Electrical shock can cause muscle contractions that injure the spine. Unless the person is in immediate danger (fire, continuing electrical hazard), do not move them until emergency responders arrive.
Step 5: Begin CPR If Needed
If the person is unconscious and not breathing after the power is disconnected, begin CPR if you are trained to do so. Continue until emergency services arrive.
Symptoms of Electrical Shock
Symptoms can range from mild to life-threatening and may not be immediately apparent:
- Burns at the entry and exit points of current
- Muscle pain and contractions
- Numbness or tingling in the affected limb
- Difficulty breathing or chest pain
- Confusion, headache, or loss of consciousness
- Irregular heartbeat or cardiac arrest
- Vision or hearing problems
- Seizures
Importantly, the external appearance of electrical injuries often understates the actual damage — OSHA notes that internal tissue damage and cardiac effects can occur even when external burns appear minor. High-voltage current travels through the body, causing internal tissue and organ damage along the current path.
After the Emergency: Electrical Inspection
After any electrical shock incident in your home, the electrical system must be inspected by a licensed electrician before it is used again. Electrical shock incidents often indicate:
- A faulty or damaged appliance or device
- Damaged wiring with exposed conductors
- Missing or failed GFCI protection in a required location
- Improper wiring that creates shock hazards
A licensed electrician can identify the hazard, make necessary repairs, and install appropriate safety devices (GFCI outlets, AFCI breakers) to prevent recurrence.
Preventing Electrical Shock at Home
- Install GFCI outlets in all required locations (bathrooms, kitchen, garage, outdoors)
- Never use damaged cords or plugs — replace immediately
- Keep electrical devices away from water
- Use outlet covers in homes with young children
- Don’t overload outlets or extension cords
- Have an electrician inspect your home’s wiring if it’s over 40 years old
Frequently Asked Questions
What should I do if someone receives an electrical shock?
First, do not touch the person if they are still in contact with the electrical source. Disconnect power at the breaker, then call 911 immediately. Do not move the person unless necessary. Begin CPR if the person is unconscious and not breathing, and you are trained to do so.
Can a minor electrical shock be dangerous?
Yes. Even low-voltage shocks can cause internal burns, muscle damage, and delayed cardiac arrhythmias. Any electrical shock should be evaluated by a medical professional — never assume a shock was “harmless” just because no immediate symptoms appear.
What should I do if I receive an electrical shock myself?
Remove yourself from the source if possible without making contact with others. Call 911 or have someone else call. Do not drive yourself to the hospital — cardiac arrhythmias can develop suddenly in the hours after a shock. Seek emergency medical evaluation immediately.
How can I prevent electrical shock in my home?
Install GFCI outlets in kitchens, bathrooms, garages, and outdoor areas. Replace damaged cords and outlets promptly. Keep electrical devices away from water. Have aging wiring (40+ years old) inspected by a licensed electrician. Use tamper-resistant outlets in homes with children.
When should I call an electrician after an electrical shock incident?
Always — after any shock incident, have a licensed electrician inspect the electrical system to identify and fix the hazard before the circuit or device is used again. The electrician should check for faulty wiring, missing GFCI protection, and any damage caused by the fault.
