The Imperative of Electrical Safety Awareness
Electricity powers our modern world, yet its potential dangers are often overlooked. In our daily lives, from homes to workplaces, the pervasive use of electrical appliances and systems demands a keen understanding and adherence to safety measures. Electrical safety awareness is not just a matter of convenience; it’s a critical element for safeguarding lives and property.
Understanding Electrical Hazards
Electricity, while invaluable, poses significant risks if mishandled. Understanding the common hazards is pivotal in promoting safety:
- Electric Shock: Direct contact with live electrical currents can cause severe injury or even death.
- Electrical Fires: Overloaded circuits, faulty wiring, or malfunctioning appliances can spark fires.
- Arc Flashes and Arc Blasts: Sudden releases of energy due to electrical faults can cause explosions, resulting in severe burns and other injuries.
Accidents from electricity can have serious consequences, such as injuries, damage to property, and fatalities. Some common types of electrical accidents are:
- Electric shocks from faulty wiring or equipment.
- Electrical fires from faulty wiring, overheated equipment, or electrical faults.
- Falling due to an electric shock.
The main reasons for these accidents are:
- People not using equipment properly.
- People using damaged or faulty equipment.
- Using equipment that is thought to be dead but is still live.
- Not having appropriate training with live equipment.
Not only is contact with live electrical parts dangerous, but contact through a conductive material allowing the electrical charge to transfer is also threatening. Fuses and circuit breakers are safety devices that help reduce the risks of electric shocks and fires, but it is possible for these to fail. Voltages which are over 50 volts AC, or 120 DC, are looked upon as hazardous.
Types of Accidents and Injuries
- Electric Shock – Electric shocks are dangerous and potentially life-threatening, and they happen when the body encounters a live electrical current.
- Muscle Control – Electric shocks can affect the body’s nervous system and lead to involuntary muscle contractions and loss of muscle control. It is possible to get broken bones or dislocated joints when the muscle spasms are powerful enough.
- Electrical Burns – Electrical burns are injuries to the skin and underlying tissue and are caused by contact with an electric current. When the current travels through the body, it heats the tissue and can damage blood vessels, nerves and bones, leading to scarring and possible long-term complications.
- Thermal Burns – This type of burn injury occurs if skin or body tissue is exposed to excessive heat, flames, steam, hot liquids, or other sources of high temperature. Sunburn can also be a form of thermal burn.
Promoting Electrical Safety Awareness
To work safely around electricity, there are a few basic rules to follow:
- Choose the correct equipment for the job at hand, avoiding electrical stress or overload.
- Make sure light bulbs and fragile equipment are protected.
- Do not overload power sockets; adaptors can cause a fire.
- Portable equipment should be connected to sockets that are close by, easy to access and easy to disconnect in an emergency.
- If an appliance frequently blows a fuse or trips a circuit breaker, disconnect the appliance straight away and either get a licensed tradesperson to fix it or replace it with a new appliance.
- Never leave cables from electrical or portable equipment where they could be tripped over.
- Before plugging something in or out, always switch off the power supply.
- Ensure appliances are switched off and unplugged when not in use and overnight.
The Electricity at Work Regulations 1989
The purpose of these regulations is for precautions to be taken against the risk of death or personal injury from electricity in work activities. The regulations apply to all work activities and operations involving electrical systems, equipment, and installations.
This includes all types and categories of electrical work, from the installation of new equipment to its maintenance and operation. All equipment should be suitable for, and only used for its intended purpose. Hazardous environments should have equipment that is designed appropriately or have adequate protection in place to avoid danger.
Employers have a duty to make sure that employees and contractors working on electrical systems are competent and adequately trained to perform their tasks safely. Electrical installations should be carried out by competent persons who are knowledgeable and skilled in electrical work.
The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations is a legal framework that requires employers, the self-employed, and people in control of work premises to report certain types of workplace incidents and occupational diseases. It also covers incidents such as certain dangerous occurrences and near misses that have the potential to cause harm.
Incidents should be reported as soon as possible or within specified timeframes outlined in the regulations and should be reported to the HSE or the relevant enforcing authority. The following incidents involving electricity should be reported immediately:
- An explosion or fire caused by an electrical overload or short circuit.
- An employee suffers unconsciousness due to an electric shock or burn and needs resuscitation or hospital admission.
- Plant equipment coming into contact with overhead power lines.
Electrical safety awareness is not a mere checklist but a responsibility that extends to every individual. By fostering a culture that values and prioritises electrical safety through education, adherence to regulations, and practical precautions, we can mitigate risks and ensure a safer, more secure workplace and future for all. Remember, when it comes to electricity, knowledge and vigilance are our most potent tools in safeguarding lives and property.
