6 Types of Electrical Burns: Danger and Prevention

An electrical burn occurs when an electric current passes through the body, generating heat and damaging tissue. Unlike thermal burns caused by direct heat sources, electrical burns can penetrate deep into muscles, nerves, and organs. They are often more complex than surface injuries and may appear deceptively minor on the skin, hiding significant internal damage.

Common Causes of Electrical Burns:

• Faulty wiring or exposed conductors

• Improper use of electrical tools

• Contact with power lines

• Poorly maintained electrical equipment

• Lightning strikes

• Human error during maintenance or repairs

Overview of the 6 Types of Electrical Burns

Here are the six major types of electrical burns we’ll discuss in detail:

1. Flash Burns

2. Flame Burns

3. Lightning Burns

4. True Electrical Burns (Contact Burns)

5. Arc Burns

6. Oral Burns (especially in children)

Let’s get into each.

1. Flash Burns

Flash burns are caused by an arc flash or explosion, not by direct contact with the electrical source. The intense heat from the arc can vaporize metal, ignite clothing, and cause severe skin burns.

Key Characteristics:

• No current passes through the body

• Affects exposed areas (face, neck, hands)

• Often superficial, but can be extensive

• Accompanied by ultraviolet (UV) radiation exposure

Causes:

• Arc flash from high-voltage equipment

• Switching devices without proper arc-rated PPE

• Static discharges in explosive environments

Symptoms:

• Redness and blistering of the skin

• Dry or leathery skin texture

• Severe eye damage (arc eye)

• Pain and inflammation

Real-life Scenario:

A technician operating a switchgear without arc-rated gloves experienced an arc flash. Though he wasn’t electrocuted, the flash burned both his hands and face within seconds.

First Aid Tips:

• Move the person away from the source

• Cool the area with running water for 10–20 minutes

• Do not apply creams or ointments

• Cover with a sterile, non-stick bandage

• Seek immediate medical help

Prevention:

• Wear flame-resistant clothing

• Use insulated tools and PPE

• Implement Lockout/Tagout (LOTO)

• Maintain equipment regularly

2. Flame Burns

Flame burns occur when an electrical arc ignites nearby materials, including clothing. Unlike flash burns, flame burns may result from direct ignition and not just thermal radiation.

Key Characteristics:

• Burn is caused by fire, not electricity

• Often deep and extensive

• Can lead to inhalation injuries

Common Causes:

• Electric sparks from overloaded circuits

• Flammable gases ignited by an arc

• Short-circuited wires near combustible materials

Symptoms:

• Blackened or charred skin

• Clothing melted into the skin

• Blistering, swelling, and intense pain

• Possible airway obstruction (if inhalation occurred)

Case Example:

A welder’s arc struck a nearby fuel container, igniting a fire. The worker suffered third-degree burns on his arms and chest due to flame exposure, not electrical contact.

Treatment Guidelines:

• Extinguish flames using water, a fire extinguisher, or the stop-drop-roll method

• Cool the affected area

• Monitor for signs of respiratory distress

• Call emergency services

Safety Measures:

• Store flammables away from electrical panels

• Train workers on fire prevention

• Conduct regular fire risk assessments

• Use flame-retardant PPE

3. Lightning Burns

Lightning burns result from natural electrical discharges with extremely high voltage (up to 1 billion volts). These burns can be fatal or leave survivors with permanent injuries.

Distinct Features:

• Often, entry and exit wounds

• Lichtenberg figures (fern-like skin patterns)

• Internal organ damage is possible

• Cardiac or respiratory arrest risk

Causes:

• Direct strike

• Side splash from a nearby object

• Ground current conduction

Symptoms:

• Burn marks on the skin

• Confusion or unconsciousness

• Irregular heartbeat

• Severe muscle pain

• Temporary or permanent paralysis

Real-World Example:

In 2023, a farmer in Kansas was struck by lightning while tending to his field. He survived due to immediate CPR from a nearby colleague but suffered burns along his left shoulder and leg, with deep nerve damage.

Treatment Tips:

• Call emergency services immediately

• Start CPR if necessary

• Treat burns with a sterile dressing

• Keep the victim warm and calm

Prevention:

• Avoid open fields during thunderstorms

• Stay inside metal-roofed vehicles or buildings

• Install lightning arresters in high-risk areas

4. True Electrical Burns (Contact Burns)

These are the most severe types of electrical burns, resulting from direct contact with an energized source. The current enters at one point and exits at another, cooking internal tissue along its path.

Key Features:

• Entry and exit wounds

• Deep tissue and organ damage

• Often life-threatening

• Can cause fractures, heart arrhythmias

Usual Causes:

• Holding live wires or tools

• Unprotected repair of energized equipment

• High-voltage exposure

Symptoms:

• Small entry wound, but deep internal damage

• Muscle breakdown (rhabdomyolysis)

• Seizures or cardiac arrest

• Loss of consciousness

Example Scenario:

An electrician accidentally touched a live 11,000-volt cable. He had minimal skin burns but lost sensation in his arm due to deep nerve damage and required multiple surgeries.

Treatment Approach:

• Call emergency responders

• Do not touch the victim until the power source is shut off

• Start CPR if unresponsive

• Administer IV fluids (in hospital)

• Monitor for organ dysfunction

Safety Guidelines:

• De-energize equipment before work

• Use Lockout/Tagout systems

• Always verify the absence of voltage

• Use insulated gloves and boots

5. Arc Burns

Arc burns occur when electrical energy travels through the air, producing intense heat without direct contact. Often confused with flash burns, arc burns tend to have more explosive effects.

How They Differ:

• Result from electric arcs, not full circuits

• Can cause thermal and blast injuries

• Dangerous in high-voltage systems

Causes:

• Dropped tools creating an arc

• Switching electrical circuits without PPE

• Dust or corrosion causing arc faults

Symptoms:

• Burns on exposed body parts

• Ruptured eardrums (due to blast)

• Shrapnel wounds

• Eye injuries (from a bright flash)

Real-Life Case:

A lineman working on a transformer experienced an arc blast after a tool slipped. Although he wore a face shield, his arms were burned, and he was thrown 5 feet by the force.

Immediate Action:

• Remove from the danger zone

• Cool the burns with water

• Treat blast injuries

• Emergency medical evacuation

Preventive Steps:

• Install arc-fault protection devices

• Use arc-rated PPE (not just regular flame-resistant gear)

• Perform electrical risk assessments

• Keep tools properly insulated

6. Oral Burns (Common in Children)

Oral electrical burns are common in young children, especially toddlers who bite into electrical cords. These burns affect the mouth, lips, and surrounding areas, potentially leading to permanent disfigurement.

Why Children Are Vulnerable:

• Teething infants explore with their mouths

• Lack of awareness of electrical dangers

• Unsupervised play around cords

Symptoms:

• Burns on the inner or outer lip

• Swelling, drooling, and refusal to eat

• Bleeding from the corners of the mouth

• Speech or developmental issues (long-term)

Example:

A 2-year-old in Texas bit into an extension cord while unsupervised. The result was a third-degree burn on the lower lip and damage to nearby teeth, requiring reconstructive surgery.

First Aid Tips:

• Disconnect the power source immediately

• Rinse the mouth with cool water (if conscious)

• Avoid inserting anything into the mouth

• Seek immediate pediatric emergency care

Prevention:

• Use cord covers and outlet protectors

• Keep cords out of reach

• Educate caregivers on childproofing

• Buy chew-safe toys for teething infants

Long-Term Effects of Electrical Burns

Electrical burns don’t end with initial treatment. Survivors may face:

• Chronic pain

• Muscle weakness

• Nerve damage

• Psychological trauma

• Amputations

• Infections or sepsis

Rehabilitation may involve physical therapy, reconstructive surgery, and mental health counseling.
