Responding to Electrical Emergencies and Shocks
The Problem
Electrical emergencies can happen without warning and often result in serious injuries or fatalities. Whether it’s electric shock, a downed power line, or equipment failure, knowing how to respond quickly and correctly can save lives. Today, we’ll discuss how to recognise electrical emergencies, respond safely, and prevent further harm.
Identify the Hazards
- Electric Shock: Contact with live wiring, faulty tools, or poor earthing.
- Electrical Fires: Overloaded circuits or malfunctioning equipment igniting fires.
- Arc Flashes and Explosions: Sudden discharge of electrical energy causing severe burns and trauma.
- Downed Power Lines: Often energised and extremely hazardous.
- Delayed Effects: Internal injuries, cardiac issues, or other symptoms may arise after a shock.
Safety Practices and Preventative Measures
Recognise an Electrical Emergency:
- Signs include sparks, smoke, loud buzzing or cracking sounds, or an unresponsive worker near electrical equipment.
- Always assume electrical sources are live until verified safe by a competent person.
Respond Safely to Electric Shock Incidents:
- DO NOT Touch the Victim: If they are still in contact with the source, you could also be shocked.
- Cut the Power: Switch off the power source immediately. If not accessible, use a dry, non-conductive object (e.g., a wooden stick or plastic tool) to separate the victim.
Call for Emergency Help:
- Dial 111 for emergency services. Provide clear information about the incident and location.
- Notify your supervisor or site safety representative immediately.
Administer First Aid (If Safe):
- Only approach the victim once the power is confirmed to be off.
- Check for breathing and pulse.
- If trained in CPR, begin immediately if the victim is unresponsive.
- Cover any burns with a sterile, non-stick dressing. Do not apply ointments or creams.
Prevent Electrical Fires:
- Use Class C fire extinguishers suitable for electrical fires.
- Never use water—it conducts electricity and may worsen the hazard.
- Evacuate the area if the fire becomes unmanageable.
Prepare for Arc Flashes:
- Use arc-rated PPE including flame-resistant clothing, gloves, and face shields when working near energised equipment.
Post-Emergency Steps:
- Report the Incident: Complete an incident report with your supervisor.
- Inspect Equipment: Have damaged equipment isolated and checked by a registered electrician before reuse.
Real-Life Case or Scenario
A worker received a serious electric shock from a faulty extension lead. A colleague rushed in and grabbed them, also receiving a shock. Neither worker had isolated the power first. The incident could have been avoided with proper electrical safety training and emergency response awareness.
Employee Responsibilities
- Recognise and report electrical hazards immediately.
- Never assist a shock victim until the power source has been isolated.
- Use the correct PPE and tools for electrical work.
- Stay alert and avoid complacency with electrical tasks.
Employer Responsibilities
- Provide training on recognising and responding to electrical emergencies.
- Ensure emergency equipment (e.g. RCDs, fire extinguishers, first aid kits) is accessible and maintained.
- Conduct regular inspections to identify and address electrical hazards.
- Develop and communicate a clear electrical emergency response plan.
Discussion & Questions
- “What would you do if you saw a co-worker receive an electric shock?”
- “Has anyone experienced an electrical emergency on-site? How was it handled?”
- “Are there any areas on-site that could use better controls or safeguards for electrical safety?”
Encourage employees to share experiences, ask questions, and suggest improvements.
Commitment/Action Plan
Let’s commit to improving our preparedness for electrical emergencies. Starting today, familiarise yourself with the location of RCDs, switchboards, fire extinguishers, and emergency contacts. Always check your equipment before use and report anything unsafe straight away.
Wrap-Up
Electrical emergencies can happen anywhere, at any time. But with knowledge, quick thinking, and adherence to proper procedures, we can prevent serious harm and save lives. Thank you for your attention and for taking responsibility for your safety and the safety of your team.
Standards Overview
Under the Health and Safety at Work Act 2015 (HSWA), PCBUs (Persons Conducting a Business or Undertaking) must identify and manage electrical risks, including emergency response planning. WorkSafe NZ expects:
- Training for workers to recognise and respond to electrical emergencies
- Access to suitable fire extinguishers (Class C or multi-class dry chemical)
- Proper use of personal protective equipment (PPE) for arc flash and electrical work
- Isolation procedures (lockout/tagout) to prevent unintended energisation
