Despite these advancements in enhancing work health and safety standards, it's crucial to note that every work-related fatality is a tragedy. Ongoing efforts to ensure workplace electrical safety remain essential for reducing hazards like electrical injuries and death.

Quick summary: Electrical emergency preparedness means having clear procedures, trained workers, and the right equipment ready before an incident occurs. Contractors and tradespeople who understand common electrical hazards, wear proper PPE, and follow tested response plans reduce their risk of shock, fire, and equipment damage on site.

Electrical emergency preparedness is critical to workplace safety, especially for contractors and trades workers. This guide provides valuable information and resources to help contractors and tradespeople prepare for electrical emergencies, including how to identify hazards, respond safely, and build lasting management plans suited to their sites.

Types of Electrical Emergencies

Contractors handle client tasks, including construction, electrical work, plumbing, painting, and landscaping. Tradespeople, or merchants, are skilled workers in trades like electricians, plumbers, carpenters, HVAC technicians, welders, and mechanics. Both face risk of encountering electrical emergencies while on the job.

In a recent event in Queensland in November 2023, a roofer working on top of a single-story house being built suffered an injury. Incident occurred when a metal roof truss contacted an electrical conductor during relocation. This occurrence falls under the Serious Electrical Incidents (SEI) category defined by the Electrical Safety Act of 2002 (ES Act). Such incidents highlight importance of preparedness for electrical emergencies.

This incident is just one example of many electrical emergencies on a job site. These emergencies can range from minor shocks and burns to more severe incidents such as house fires or electrocutions.

Electrical Shock

Contact with live electrical wires or equipment can result in electric shock, causing burns, cardiac arrest, or even death.

Power Outages

Unexpected power outages can arise from various factors, including extreme weather conditions, equipment malfunctions, or grid surges. While not always life-threatening, outages can disrupt daily activities and compromise electrical safety, especially in critical environments like hospitals or industrial facilities.

Electrical Storm Damage

Lightning strikes or power surges during storms can cause extensive damage to electrical systems, leading to fires, power outages, or equipment failure.

Electrical Equipment Malfunction

Faulty or poorly maintained electrical equipment can malfunction, leading to sparks, smoke, or even explosions. This can happen in residential, commercial, or industrial settings and requires immediate attention to prevent further damage or injury.

Downed Power Lines

Fallen power lines pose significant danger, whether due to storms, accidents, or other causes. Lines can still be live and carry high voltages, making them extremely hazardous.

Electrical Substation Emergencies

Issues at electrical substations, such as equipment failures, transformer explosions, or fires, can disrupt power distribution on a large scale and require prompt intervention by trained professionals.

Arc Flashes and Arc Blasts

These occur when electrical current arcs through the air, generating intense heat and pressure. Arc flashes and blasts can cause severe burns, blast injuries, and damage to surrounding equipment and structures.

Carbon Monoxide Poisoning

Malfunctioning electrical appliances, such as generators or heating systems, can produce carbon monoxide (CO) gas, which is odourless and colourless but highly toxic.

Electrical Accidents in Water

Electrical appliances or equipment near water sources, such as swimming pools, bathrooms, or flooded areas, can pose a significant electrocution risk.

Common Causes of Electrical Emergencies

Understanding root causes of electrical emergencies remains essential for prevention. Emergencies described above stem from various factors, including:

• Overloaded circuits: When too many electrical appliances or equipment plug into the same circuit, overloading the system can cause a fire.
• Old or damaged wiring: Worn-out or damaged wiring can cause short circuits, leading to electrical fires.
• Wet conditions: Water conducts electricity, and when it comes into contact with an electrical source, electrocution can result.
• Faulty wiring or equipment: Faulty wiring or equipment can cause electrical fires and other emergencies.
• Improper use of extension cords: Using extension cords for long periods or connecting multiple devices to one cord can overload systems and potentially cause a fire.
• Lack of maintenance: Failure to regularly inspect and maintain electrical systems can lead to malfunctions and emergencies.
• Overhead and underground power lines: Contact with overhead or underground lines can cause electrocution and electrical fires.
• Flammable materials: Placing flammable materials near electrical sources can quickly lead to a fire in case of a spark or short circuit.
• Inadequate isolation and lockout/tag-out procedures: Failing to properly isolate and secure electrical systems during maintenance or repair can lead to severe accidents.

How to Respond to Electrical Emergencies

Never make physical contact with someone experiencing an electric shock. Instead, turn off power source using a circuit breaker or unplug the appliance if safe to do so.

If you cannot safely turn off power, try to move affected individuals away from the electricity source using a non-conductive object such as a wooden broom handle. Call 000 and seek medical attention immediately.

In case of an electrical fire, avoid using water to extinguish flames, since this can cause electrocution. Instead, use a Class C fire extinguisher specifically designed for electrical fires or smother flames with a heavy blanket or coat.

Never attempt to repair electrical equipment yourself. Always hire a licensed electrician for repairs or installations to avoid accidents.

Start cardiopulmonary resuscitation (CPR) if a person shows no signs of breathing or life. Begin with chest compressions and follow instructions given by emergency services until medical professionals arrive.

During a power outage, unplug all appliances and turn off light switches until power gets restored. This prevents a surge of electricity when power returns, which can cause damage to appliances and potentially start fires.

Preventing Electrical Emergencies

Knowing what to do during electrical emergencies isn't enough on its own. Equally important is understanding how to prevent incidents from happening in the first place. Here are ways to prevent electrical emergencies:

1. Provide Essential Electrical Safety Equipment

Personal Protective Equipment (PPE)

Contractors and tradespeople should always wear appropriate PPE when working with or around electrical systems. This includes insulated gloves, safety goggles, and non-conductive footwear to minimise risk of electrical shock. Selecting the correct PPE for each task helps reduce exposure to hazardous voltages and arc-related hazards.

Emergency Response Kits

Emergency response kits should stay readily available on worksites and be equipped with essential tools such as voltage testers, insulated tools, and fire extinguishers. These kits enable prompt and effective responses to electrical emergencies.

2. Establish Emergency Procedures and Protocols

During an electrical emergency, following established procedures promptly proves crucial. This may include:

Designated Emergency Response Team

Having a designated team responsible for responding to electrical emergencies remains essential. Team members should be trained in handling different electrical issues and incidents and equipped with necessary knowledge and tools.

Communication Protocols

Proper communication proves crucial during an electrical emergency. All workers on site must know who to contact in case of an incident, how to communicate effectively, and when to call for professional assistance. Clear communication channels also support faster evacuation when a site must be cleared quickly.

3. Provide Training and Education for Electrical Emergencies

First Aid for Electrical Shock

Knowing how to administer first aid for electrical shock incidents can be life-saving. Immediate actions for electric shock may include shutting off power, performing CPR if necessary, and seeking medical attention for the injured individual.

CPR Training

Contractors and tradespeople should undergo CPR training to respond to cardiac emergencies resulting from electrical shocks or other incidents. Timely administration of CPR can greatly enhance the victim's chance of survival.

Fire Extinguisher Training

All workers should receive training in properly using fire extinguishers to extinguish small fires safely. Understanding different types of extinguishers and their applications proves essential for effective fire suppression.

4. Secure the Worksite

Lockout/Tagout Procedures

Lockout/tagout procedures prove essential for preventing unexpected startup of equipment or machinery during power outages. This means securing all energy sources to avoid accidental re-energisation, helping keep workers safe.

Fire Suppression Equipment

Having appropriate fire suppression equipment on-site, such as fire extinguishers and sprinkler systems, can help contain fires and limit damage during emergencies. Employees need training in how to use this equipment effectively.

Emergency Shut-off Valves

Ensure all emergency shut-off valves stay easily accessible and labelled clearly in case of a power outage. These valves allow quick and safe shutdown of gas, electricity, water, or other hazardous materials during an emergency.

5. Conduct Regular Maintenance

Regularly scheduled maintenance and inspections of all equipment and machinery can help identify potential risks or malfunctions before they become a problem during a power outage. Ensure all manufacturers' recommended maintenance schedules get followed, and keep records of these activities.

Inspections and Testing

Routine inspections and testing of electrical systems help ensure their integrity and functionality. Identifying and addressing deficiencies promptly can mitigate risks and prolong lifespan of electrical infrastructures. For sites with complex installations, scheduling testing alongside routine servicing of vehicles and mobile plant supports a more complete safety approach.

6. Implement Post-Emergency Assessment and Documentation

Examples of necessary documentation in preventing electrical emergencies include:

• Detailed Incident Records: Maintaining detailed records of electrical incidents, actions taken, and outcomes proves crucial for learning from past emergencies and improving electrical safety rules.
• Safe Operating Procedures (SOPs): Detailed instructions for adequately operating electrical equipment, including intended use, safety procedures, hazard information, and recommended accessories, remain vital for preventing misuse and accidents.
• Inspection Reports: Regular electrical system inspections by qualified personnel to spot hazards, take immediate action to reduce risks, and ensure safety compliance prove crucial for preventing emergencies.
• Training Records: Keeping records of employee and household member training on electrical safety, including hazard identification, safe device usage, and emergency response procedures, proves crucial for reducing risk of accidents.

7. Develop an Electrical Emergency Response Plan

An Electrical Emergency Response Plan offers a comprehensive strategy designed to guide contractors, tradespeople, and other personnel in effectively responding to electrical emergencies. It includes steps for assessing the situation, ensuring safety of individuals, and minimising property damage. Additionally, the plan may detail communication protocols, evacuation procedures, and personnel roles and responsibilities during emergencies.

Investing in a robust plan proves crucial not only for employee safety but also demonstrates commitment to compliance with health and safety regulations. Employers must ensure a safe work environment for their employees as a legal responsibility, encompassing proper training and implementation of emergency response controls. Businesses managing subcontractors on site should also review WHS documentation for principal contractors and subcontractors to confirm electrical responsibilities get clearly assigned.
