Responding to Electrical Emergencies and Shocks

Electrocution | OSHA Fatal Four

The Problem

Electrical emergencies can happen in an instant, and they often result in serious injuries or even fatalities. Whether it's an electric shock, a downed power line, or an equipment failure, knowing how to respond quickly and correctly can save lives. Today, we’ll discuss how to recognize electrical emergencies, respond safely, and prevent further injuries.

Identify the Hazards

  • Electric Shock: Contact with live wires, faulty equipment, or improper grounding.
  • Electrical Fires: Overloaded circuits or malfunctioning equipment can ignite fires.
  • Arc Flashes and Explosions: Sudden release of electrical energy causing burns and trauma.
  • Downed Power Lines: Often energized, creating risk of shock or electrocution.‍
  • Delayed Effects: Electric shock can cause internal injuries, heart issues, or other delayed symptoms.

Safety Practices and Preventative Measures

  1. Recognize an Electrical Emergency:

    • Signs of an emergency include sparks, smoke, loud electrical sounds, or an unresponsive worker near electrical equipment.
    • Assume all electrical hazards are energized until confirmed safe.
  2. Respond Safely to Electric Shock Incidents:

    • DO NOT Touch the Victim: If the victim is still in contact with the electrical source, touching them could transfer the current to you.
    • Cut the Power: Locate the power source and turn it off immediately. If it’s not accessible, use a non-conductive object like a wooden pole to separate the victim from the source.
  3. Call for Emergency Help:

    • Dial 911 and inform them of an electrical injury. Provide clear information about the incident and location.
    • Notify your supervisor or site safety officer immediately.
  4. Administer First Aid (If Safe):

    • Only approach the victim once the power is off. Check for breathing and a pulse.
    • If trained, begin CPR if the victim is not breathing.
    • Cover burns with a sterile, non-adhesive dressing—do not use ointments or creams.
  5. Prevent Electrical Fires:

    • Use only Class C fire extinguishers for electrical fires. Never use water on an electrical fire—it can conduct electricity.
    • Evacuate the area if the fire cannot be controlled.
  6. Prepare for Arc Flashes:

    • Ensure workers wear the proper PPE, such as arc-rated clothing, gloves, and face shields, to reduce injuries from arc flashes.
  7. Post-Emergency Steps:

    • Report the Incident: Fill out an incident report with your supervisor.‍
    • Inspect Equipment: Have a qualified electrician assess and repair any damaged equipment before resuming operations.

Real-Life Case or Scenario

Where possible, use an actual incident that you have experienced or been involved in.

E.g. In a recent incident, a worker received a severe shock while using a faulty extension cord. A coworker tried to help by grabbing the worker without cutting the power, resulting in a second injury. The situation escalated unnecessarily because proper procedures weren’t followed. These accidents show why it’s critical to understand and follow electrical emergency response protocols.

Employee Responsibilities

  • Recognize the signs of electrical hazards and emergencies.
  • Never attempt to assist a shock victim without ensuring the power is off.
  • Use proper tools and PPE for electrical tasks to prevent accidents.
  • Report any damaged equipment or unsafe conditions immediately.

Employer Responsibilities

  • Provide training on electrical hazard recognition and emergency response.
  • Ensure emergency response equipment, like fire extinguishers, is accessible and maintained.
  • Conduct regular inspections to identify and address electrical hazards.
  • Develop and communicate an emergency response plan for electrical incidents.

Discussion & Questions

  • "What would you do if you saw a coworker get shocked while working with live equipment?"
  • "Have you ever encountered an electrical emergency? How was it handled?"
  • "Are there any areas on-site where you feel additional safety measures are needed for electrical work?"

Commitment/Action Plan

Let’s commit to improving our emergency response readiness. Starting today, review the location of circuit breakers, fire extinguishers, and emergency contacts. Always double-check your equipment before use and report any issues immediately.

Wrap-Up

Electrical emergencies can happen anywhere, but with the right knowledge and quick action, we can prevent injuries and save lives. Thank you for your attention and for taking safety seriously. Remember, safety is everyone’s responsibility.

Standards Overview

  • OSHA requires that employees working around electrical hazards must be trained to recognize and respond to electrical emergencies (OSHA 1910.331-335).
  • Proper procedures for emergency response, including first aid for electrical shock victims, are critical for workplace safety.
  • The Lockout/Tagout Standard (OSHA 1910.147) also plays a role in preventing electrical accidents.
