Introduction
According to the Nigerian Electricity Regulatory Commission (NERC), in the first quarter of 2025, Nigeria recorded 31 electricity-related health and safety incidents, resulting in 12 fatalities and 14 injuries.
Major causes include high-tension power lines, substandard materials, and lack of personal protective equipment (PPE).
It is important to know how to prevent them before they happen because they are quite common and extremely deadly.
Whether it is in your office, home, or site, here, you will learn how to prevent electric shocks that can lead to loss of life.
What Is an Electric Shock?
An electric shock is what happens when a body comes in contact with a source of electricity such that the electric current travels through the body, causing the muscles to seize involuntarily.
Now there is electric shock, and there is electrocution. While there is a link between these two, what differentiates an electrical shock from electrocution is that the latter results in death.
Causes of Electric Shock
Some causes of electrical shock include:
- Damaged wires.
- Overloaded outlets.
- Electrical work done by a nonprofessional.
- Using substandard or already damaged electrical products and accessories.
- Wet hands or wet environment.
- Lightning strike.
- Lack of Personal Protective Equipment (PPE).
- Electrical appliances coming in contact with water.
- Fallen or downed powerline.
It is important to know that faulty or unprofessional electrical installations, as well as carelessness, are the major causes of electrical shock.
Electric Shock Prevention
Electrical shocks can be prevented by ensuring safety measures are implemented in the home, office, and sites.
1. Wear Personal Protective Equipment (PPE): wear rubber-soled shoes and insulated safety gloves when operating power tools, replacing fuses, or working with any device that can give electric shock.
2. Ground All Power Supply Systems: Ensure electrical systems and power circuits are properly grounded by your electrician or electrical engineer. This is a very effective electric shock prevention technique for every building.
3. Do Not Overload Circuit: Circuit breakers automatically cut off power when there is an overload or short circuit; this is essential in electrical safety. Getting circuit breakers like Schneider’s, which automatically turn off power once there is an overload, is highly recommended.
4. Avoid faulty or substandard electrical products: use of low-quality products leads to a higher risk of electrical malfunction, which can lead to electric shock. Flux energy provides Schneider Electric products with quality that has been tested and trusted over the years.
5. Stay Far From A Fallen Powerline: if a powerline has fallen, try as much as possible not to go close to the area where the powerline has fallen. Also, if it is down on your car, the car tires serve as an insulator for electricity, and this will prevent electrocution. Stay in your car and wait until help comes.
6. Ensure Your Hands And Feet Are Always Dry: when you are in the field or at home handling electrical wires and appliances and you notice any damaged or exposed wires, the first electrical safety measure is to ensure your body is dry.
7. Educate The People Around You About Electrical Safety: enlighten your workers and kids about electrical safety, the signs to look out for in case of an electrical mishap, and what to do and what not to do during such cases.
Knowing how to prevent electric shock will go a long way in safeguarding our homes, offices, and sites.
Effects of Electric Shock
The effects of electric shock on the human body include:
- Burns: This includes first-degree, second-degree, third-degree, and fourth-degree burns.
- Compartment syndrome: this occurs when the area of the electric shock begins to swell.
- Traumatic injury: this may happen during a powerful electric shock occurrence, which results in cases where the victim is thrown, which can result in bumps or a great fall if the electric shock happens at a great height, leading to an injury.
- Internal damage: Most of the injuries caused by electric shock may not be seen on the outside; since the electric current travels internally, it can lead to tissue or organ damage.
Other effects of electric shock include:
- Generalized body pain
- Post-traumatic stress disorder (PTSD)
- Eye problems
- Muscle pain
- Development of phobia
- Anxiety
- Dizziness
- Migraine
Electric Shock Protection Devices
Electric devices that protect against shock include:
- Circuit breakers
- Surge protectors: they protect your electronics against sudden increases in electric current that could have led to shocks.
- Fuses.
Others include:
4. Personal Protective Devices (PPE): serve as an insulation between electrical current and the human body. They are mostly devices made from rubber, which serve as an insulator. Some of them include insulated gloves, hard hat, insulated footwear, depending on the intensity of the voltage.
5. Insulated electrical tools.
Conclusion
Knowing how to prevent electrical shock is very important. It can save lives at home, in the office, and on worksites.
Damaged wires, wrong use of appliances, or lack of safety tools, are the main causes of electrical shock, the good news is that they can be avoided.
Simple steps like wearing protective equipment, keeping your hands dry, avoiding overloaded sockets, and staying away from fallen power lines are practical ways to stay safe.
Using quality products and protection devices such as circuit breakers and surge protectors also play a big role.
We can reduce accidents, protect the people and things we care about by teaching others how to prevent electrical shock and by following safety rules ourselves.
At the end of the day, learning how to prevent electrical shock is not just safety advice; it is a responsibility we all share.
