Electrical burns are serious injuries that require specific first aid treatment and urgent medical attention. These burns occur when electric current passes through the body, causing damage to tissues both at the entry and exit points, as well as potentially damaging internal organs. Proper electrical burn first aid involves ensuring scene safety, disconnecting power sources, cooling the burn with running water for at least 20 minutes (when safe to do so), and seeking immediate medical care. This comprehensive guide outlines the critical first aid steps for electrical burns, relevant Australian guidelines, and when to seek emergency medical assistance.
Electrical injuries pose unique challenges compared to other types of burns due to their potential for internal damage that may not be immediately visible. In Australian workplaces, particularly in construction, mining, and utility sectors, understanding proper electrical burn management can mean the difference between life and death.

Understanding Electrical Burns
Electrical burns differ significantly from thermal burns or scalds, as they can cause damage beneath the skin that isn’t immediately visible. Proper assessment and understanding of these injuries is crucial for effective first aid response.
| Type of Electrical Burn | Description | Common Causes |
|---|---|---|
| Contact burns | Direct contact with electrical source | Touching live wires, faulty equipment |
| Arc burns | Flash burn from electrical arc | High-voltage equipment, lightning |
| Flame burns | Secondary burns from ignited clothing | Electrical fires, explosions |
| Thermal burns | Heat transfer from electrical current | Prolonged contact with heated surfaces |
Electrical burns include damage that occurs when current passes through the body. The severity depends on several factors including voltage, type of current (AC or DC), pathway through the body, duration of contact, and individual factors such as moisture level of the skin.
High-voltage burns (over 1000 volts) typically cause more severe damage than low-voltage burns, often resulting in full thickness burns at both entry and exit points. The current pathway is particularly concerning when it passes through vital organs such as the heart or brain.
Entry and Exit Wounds
Identifying entry and exit wounds is crucial when assessing electrical injuries:
- Entry wounds often appear as small, charred, depressed areas
- Exit wounds typically look larger and more explosive
- Both may appear as full thickness burns with minimal pain due to nerve damage
- The absence of an exit wound may indicate that electricity is still contained within the body
Internal injuries from electrical burns may not be immediately apparent but can cause significant tissue damage, organ dysfunction, and cardiovascular complications.
Initial Emergency Response for Electrical Burns
Safety First: Securing the Scene
The primary concern in any electrical incident is ensuring the safety of both rescuers and victims. Before approaching a casualty:
- Check for dangers – fallen power lines, water near electricity, or other hazards
- Never touch the casualty while they remain in contact with the electrical source
- Use appropriate personal protective equipment (PPE) if available
- Prevent others from approaching the hazardous area
Power Disconnection Procedures
Safely disconnecting the power is critical before administering first aid:
- If possible, switch off power at the source or unplug the device
- For high-voltage incidents such as power lines, do not approach – call emergency services (000)
- Use non-conductive materials (dry wood, rubber, plastic) to separate the casualty from the source only if absolutely necessary and safe to do so
- Maintain a safe distance from fallen power lines (at least 10 metres)
When to Call Emergency Services
Always call Triple Zero (000) immediately for:
- Any electrical burn that appears severe
- Burns associated with other injuries
- Any incident involving high-voltage electricity
- Casualties showing signs of shock or altered consciousness
- Electrical burns to the face, hands, feet, genitals, or major joints
- Burns that appear to be full thickness
- Any electrical injury in pregnant women, children, or elderly individuals
Remember to provide clear information about the electrical nature of the incident when calling emergency services to ensure appropriate resources are dispatched.
Electrical Burn First Aid Procedure
Assessment of Responsiveness and Vital Signs
- Check for responsiveness by talking to the casualty and gently tapping their shoulders
- If unresponsive, check for breathing and pulse
- If not breathing normally or no pulse is detected, commence CPR and use an AED if available
- For responsive casualties, monitor vital signs including breathing, pulse, level of consciousness, and symptoms of shock
CPR and Resuscitation for Electrocution Victims
For casualties who are unresponsive and not breathing normally:
- Call Triple Zero (000) immediately
- Begin CPR with chest compressions at a rate of 100 – 120 per minute (depth 5 to 6 cm) in cycles of 30 compressions followed by 2 rescue breaths
- Continue CPR until emergency services arrive, the person recovers, or you become too exhausted to continue
- If available, use an AED following the device’s instructions
Cooling the Burn
For visible burn injuries, once the casualty is separated from the electrical source:
- Cool the burn with cool running water for at least 20 minutes
- Do not use ice, butter, toothpaste, or burn creams
- Remove jewellery and constrictive clothing from affected areas if possible
- Cover the burn with a clean, non-stick dressing or plastic cling film
- Take steps to prevent hypothermia, especially when cooling large areas

Assessment of Electrical Burn Severity
Proper assessment of burn severity helps determine the urgency of medical care and appropriate electrical burn first aid measures.
| Body Area | Adult TBSA (%) | Child TBSA (%) |
|---|---|---|
| Head and neck | 9% | 18% |
| Each arm | 9% | 9% |
| Chest | 18% | 18% |
| Back | 18% | 18% |
| Each leg | 18% | 13.5% |
| Genitals | 1% | 1% |
A major burn is typically defined as:
- Adults: burns covering more than 15% TBSA
- Children: burns covering more than 10% TBSA
- Any full thickness burn over 5% TBSA
- Burns to face, hands, feet, genitals, or major joints
- Circumferential burns (those that go around a limb or body part)
| Burn Depth | Appearance | Sensation | Healing Time |
|---|---|---|---|
| Superficial | Red, no blisters | Painful | 3–6 days |
| Partial thickness | Red, blisters, moist | Very painful | 2–3 weeks |
| Full thickness | White/charred, dry, leathery | Minimal pain due to nerve damage | Requires surgery |
Identifying Internal Electrical Burn Injuries
Internal damage may not be immediately visible but should be suspected if:
- The casualty experienced a shock from high-voltage electricity
- They were unable to let go of the electrical source
- They were thrown by the shock
- They experienced loss of consciousness, confusion, or seizures
- They show cardiac symptoms (irregular pulse, chest pain)
- They have muscle pain, weakness, or dark urine
Special Scenarios in Electrical Burns
Lightning Strike Burn Care
Lightning strikes differ from other electrical injuries:
- Lightning delivers a massive but very brief current
- Immediate cardiac and respiratory arrest is common
- Casualties may display fernlike patterns on skin (Lichtenberg figures)
- Multiple casualties are possible in a single incident
First aid priorities include:
- Triage multiple casualties (treat those without pulse/breathing first)
- Begin CPR immediately on unresponsive, non-breathing casualties
- Monitor for seizures, confusion, and sensory disturbances
- Cool any thermal burns with running water for at least 20 minutes
Power Line Burn Emergency
For incidents involving fallen power lines:
- Stay at least 10 metres away
- Call emergency services immediately
- Warn others to keep clear
- Do not attempt to move the casualty until the power authority confirms the area is safe
- If in a vehicle that contacts power lines, remain in the vehicle unless fire forces evacuation
Electrical Burns in Remote Workplaces
For electrical burns in remote locations:
- Follow standard electrical burn first aid procedures
- Cool burns with clean running water for at least 20 minutes
- Cover with clean, dry dressing
- Monitor for signs of shock
- Arrange urgent transport to medical care
- Provide clear documentation of the incident, time of injury, and first aid provided
Medical Treatment and Transport
Appropriate Burn Dressings
After cooling the burn:
- Cover with a clean, non-stick dressing
- Alternatively, use plastic cling film (applied lengthwise, not around limbs)
- Avoid fluffy material that might stick to the burn
- Do not apply antiseptic creams or lotions
- Avoid breaking blisters
Pain Management and Transport Considerations
- Provide pain relief if available and appropriate (following workplace protocols)
- Elevate burned limbs if possible
- Keep the casualty warm to minimise the risk of hypothermia
- Monitor for signs of shock (rapid pulse, low blood pressure, pale, clammy skin)
- Transport in a position that minimises pain and pressure on burned areas
Hospital Referral Criteria
Seek immediate medical attention for:
- Any high-voltage electrical burn
- Burns with entry and exit wounds
- Burns associated with loss of consciousness
- Any burn to special areas (face, hands, feet, genitals, joints)
- Full thickness burns
- Burns covering more than 5% TBSA
- Any electrical burn in children, elderly, or those with pre-existing medical conditions
- Signs of respiratory distress or inhalation injury
- Significant pain not relieved by simple analgesics
Your quick response could save a life or prevent permanent disability.

Frequently Asked Questions
How do I safely approach someone with an electrical burn?
First, ensure the power source is disconnected or the person is no longer in contact with electricity. Never touch a person who is still in contact with an electrical source. For high-voltage incidents like fallen power lines, stay at least 10 metres away and call emergency services. Only approach once you are certain the scene is safe.
What makes electrical burns different from other types of burns?
Electrical burns are unique because they can cause severe internal damage that may not be visible on the skin surface. The electricity creates an entry and exit wound and can damage tissues, organs, and blood vessels along its path through the body. Even small external burns may be associated with significant internal injuries, particularly with high-voltage electricity.
When should I cool an electrical burn with water, and when should I not?
Cool the burn with cool running water for at least 20 minutes ONLY after ensuring the electrical source has been disconnected and it’s safe to do so. Never apply water while the person is still in contact with electricity as water conducts electrical current and could worsen the situation. If you’re unsure whether power is completely disconnected, wait for emergency services.
What should I include in an electrical burn first aid kit for the workplace?
An electrical burn first aid kit should include non-stick burn dressings, plastic cling film, clean bandages, scissors (to cut clothing if necessary), sterile gloves, blanket to prevent hypothermia, and a first aid guide specific to electrical injuries. For high-risk workplaces, additional items like AED, emergency contact information, and specific industry-relevant equipment may be necessary..
How can I tell if someone has internal injuries from an electrical burn?
Internal injuries from electrical burns may present as confusion, irregular heartbeat, difficulty breathing, muscle pain, weakness, dark urine, or seizures. Any person who has experienced an electrical shock should be assessed by a medical professional, even if external injuries appear minor, as internal damage may not be immediately obvious and can develop hours or days after the incident.
