Electrical Burns and Electrocution: First Aid Every Victorian Electrician Needs to Know

Electrical workers face hazards that most workplaces never encounter. A fault on a live circuit, an unexpected contact with an energised conductor, or a flash from switchgear can cause injuries ranging from surface burns to cardiac arrest — within a fraction of a second. Knowing how to respond in those first few minutes can be the difference between a colleague going home or not going home at all.

This post covers what electrical workers need to know about first aid response to electrocution and electrical burns, and what Victorian employers are required to have in place under WorkSafe Victoria obligations.

Why Electrical Injuries Are Different

Electrical injuries are deceptive. The external wound — a burn at the entry or exit point — often looks minor compared to the damage happening internally. When electrical current passes through the body, it follows the path of least resistance, which typically runs through nerves, blood vessels, and muscles. This can cause deep tissue destruction that isn’t visible on the surface.

Additionally, electrical current can interfere directly with the heart’s electrical system, triggering ventricular fibrillation — an irregular, ineffective heart rhythm that is fatal without immediate defibrillation. This means a worker who appears conscious and talking shortly after a shock may still go into cardiac arrest minutes later. Monitoring after any electrical contact is essential.

WorkSafe Victoria’s guidance on electrical safety notes that indirect effects such as falls are also a significant cause of injury in electrical incidents — a jolt that causes a worker to fall from a ladder or platform can result in serious trauma entirely separate from the electrical injury itself.

How to Respond to Electrocution: Step by Step

The first rule of responding to an electrical incident is: do not touch the person until you are certain the power is off. Becoming a second victim helps no one. Here is the correct sequence:

Turn off the power at the source. If you cannot isolate the power, do not approach. Call 000 immediately and wait for emergency services. For low-voltage domestic or commercial circuits, a qualified person can use a dry, non-conductive object to move the victim away from the source only if absolutely necessary — but this carries significant risk and should be a last resort.

Call 000. Do this as early as possible. Electrical injuries almost always require professional medical assessment, even when the person seems fine.

Check for responsiveness. Once the scene is safe, approach and check if the person is conscious and breathing normally. If they are unresponsive and not breathing normally, begin CPR immediately.

Start CPR if needed. Electrocution can cause cardiac arrest. Follow the standard DRSABCD action plan: Danger, Response, Send for help, Airway, Breathing, CPR, Defibrillation. Push hard and fast — 30 compressions to 2 rescue breaths — and continue until the AED arrives or paramedics take over.

Use the AED as soon as it is available. Ventricular fibrillation — one of the most common causes of death following electrocution — is a shockable rhythm. Early defibrillation significantly improves survival. Every worksite should know exactly where the nearest AED is located.

Treat for shock. Keep the person warm, calm, and lying down. Do not give food or water.

Managing Electrical Burns

Electrical burns fall into two categories: flash burns caused by the heat of an electrical arc, and contact burns where current enters or exits the body. Both require specific first aid management.

For burns from electrical contact:

Cool the burn with cool (not cold or iced) running water for 20 minutes. This is the most important step and should be started as soon as possible after the injury. Do not use ice, butter, or any other substance on the burn. Cover loosely with a clean, non-fluffy dressing or cling wrap after cooling. Do not remove clothing that is stuck to the burn. Seek immediate medical assessment — what appears to be a minor surface burn may have significant internal involvement.

For flash burns to the eyes (common in arc flash incidents), irrigation with clean water and urgent medical review are required. The cornea can be severely damaged even without obvious pain at the time of the incident.

The Australian and New Zealand Burn Association (ANZBA) guidelines recommend that all significant burns — including electrical burns — be assessed at a hospital burn unit or emergency department, regardless of apparent severity.

WorkSafe Victoria First Aid Requirements for Electrical Work

Under the Occupational Health and Safety Act 2004 (Vic) and the Occupational Health and Safety Regulations 2017 (Vic), employers must provide first aid equipment and facilities appropriate to the workplace hazards, and ensure that an adequate number of workers are trained in first aid.

WorkSafe Victoria’s guidance specifies that employers undertaking high-risk work — which includes live electrical work, work near energised equipment, and work in confined spaces — should conduct a first aid needs assessment to determine the appropriate number of first aiders, the type of equipment required, and the response procedures to be in place.

For small worksites (fewer than 10 workers), a minimum of one trained first aider is required. For larger sites or those with higher risk profiles — such as construction or electrical contracting — a higher ratio and a more comprehensive kit (including an AED where appropriate) are strongly recommended.

First aid certificates must be current. The nationally recognised unit of competency for first aid, HLTAID011 Provide First Aid, is valid for three years. CPR — HLTAID009 Provide Cardiopulmonary Resuscitation — must be renewed annually.

Keeping these qualifications current is not just a legal obligation. In a cardiac arrest following electrocution, outdated CPR technique or a lapse in confidence can cost critical seconds.

Training That Fits the Worksite

Generic first aid training is a starting point, but electrical workers benefit from training that addresses the specific hazards they face: what to do when you cannot approach immediately, how to manage a colleague who may look fine but has sustained internal injury, and how to operate an AED under pressure on a noisy worksite.

Scenario-based training and regular refreshers help workers build the kind of muscle memory that holds up when an incident actually occurs. If first aid feels unfamiliar, it is harder to act quickly under stress.
