Electrical Emergencies: Your Life-Saving Response Guide
The Problem
Electricity is an invisible but deadly hazard. Each year, it causes numerous serious incidents on Canadian worksites. Its unpredictability and the severity of its effects make electrical hazards extremely dangerous—just one small mistake can have fatal consequences. Knowing how to respond during the critical first moments of an emergency can save lives. Today, we’ll discuss the dangers of electricity, how to identify life-threatening situations, and the correct emergency responses that can protect you and your workmates.
Identify the Hazards
Electric Shock
- As little as 50 milliamps can cause heart failure.
Burn Injuries
- Electricity can cause deep internal burns.
Secondary Injuries
- Shocks can lead to falls or other serious accidents.
Life-Threatening Situations
- Downed power lines energising the surrounding ground.
- Damaged cords, plugs, or insulation.
- Standing water near electrical sources.
- Buzzing sounds, hot panels, or flickering lights from equipment.
Safety Practices and Preventative Measures
Responding to Overhead Line Emergencies
- Keep at least 10 metres away from downed power lines.
- Call emergency services (dial 911) and keep others away.
- Never try to touch or move the lines.
- If in a vehicle with a power line on it:
- Stay inside and call for help.
- If there’s a fire, jump clear with both feet together—do not touch the vehicle and the ground at the same time.
Helping Someone Being Electrocuted
- Shout for someone to call 911.
- Do not touch the person while the power is live.
- Shut off the power if it is safe to do so.
- Use dry, non-conductive objects (like timber) to separate the person from the source.
- Once safe, check for breathing and pulse, and start CPR if needed.
Preventative Measures
- Confirm all power is off before starting work.
- Use the correct PPE, including insulated gloves and tools.
- Maintain safe distances from power sources.
- Report hazards and damaged equipment immediately.
Real-Life Case or Scenario
A worker unknowingly stepped into an energised zone around a downed power line. The electricity travelled through the ground, causing immediate cardiac arrest. In another incident, a well-meaning coworker attempted to pull someone away from a live wire without isolating the power source and became a second victim. These tragedies are avoidable with the right precautions and proper emergency response.
Employee Responsibilities
- Check for electrical hazards before beginning work.
- Always wear the appropriate PPE.
- Never attempt a rescue until the electrical source has been isolated.
- Report all unsafe equipment and conditions immediately.
Employer Responsibilities
- Provide training on electrical safety and emergency response.
- Maintain tools and equipment to a safe standard.
- Supply compliant PPE and enforce its use.
- Clearly mark electrical hazards and establish emergency response plans.
