First Aid for Electrical Injuries


First Aid for Electrical Injuries

Electrical hazards can occur at any place, but they are quite common in construction sites, manufacturing plants, and homes with faulty wiring. Electrical injuries are hazardous and can cause burns, nerve damage, and even death. Injuries can happen when a person comes in direct contact with an electrical current or through electrical arcing, which occurs when the current jumps to the victim from a conductor. We can prevent electrical injuries by following safety guidelines, but accidents do happen. It is essential to know the first aid for electrical injuries to minimize damage. Here, we discuss how to treat a person who has suffered an electrical injury.

Burns

Burns occur when electrical current flows through the body and heats the tissue. They are the most common injury resulting from electrical accidents. There are three types of burns, and each requires a different first aid treatment. First-degree burns are minor burns, and they only affect the skin layer. Second-degree burns involve the epidermis and dermis, and they cause blisters and serious damage to the skin. Third-degree burns are severe and affect all the layers of skin and body tissue. They are deep, and the skin looks charred, and it requires immediate medical attention.

For first-degree burns, run it under cold water for ten to fifteen minutes to ease the pain. To treat second-degree and third-degree burns, the first action is to call for medical help. Do not touch or apply ice or any ointment directly to the burn area. Cover the affected area with a sterile gauze pad or a clean cloth to prevent infection. A cool, but not ice-cold, compress should be applied until medical services arrive.

Cardiac Arrest

Electricity can lead to cardiac arrest, where the heart stops pumping blood around the body. The accident can occur when electricity passes through the chest, resulting in ventricular fibrillation, an unorganized and useless heart rhythm. In case of cardiac arrest, begin cardiopulmonary resuscitation (CPR) immediately. Someone trained in CPR should attend to the victim while waiting for an ambulance to arrive.

Respiratory Distress

When a person receives an electric shock, the respiratory muscles can be paralysed. It can cause breathing difficulties, which if unaddressed, can progress into serious respiratory distress. Unresponsive, not breathing victims require immediate medical attention and rescue breathing assistance until breathing resumes.

Fractured Bones

When electrical accidents occur, the person may have been knocked off a ladder or another elevated location. It is possible to sustain an injury such as bone fractures when the victim falls or is thrown back by the force of the shock. If you suspect that the victim may have a fracture, lay them down as carefully as possible and call for medical assistance. Before moving the person, evaluate the injury by asking if any sudden movements cause pain.

Brain Damage

Brain damage can occur in a person who suffers a severe shock. Electrical currents can interfere with the central nervous system and cause seizures, memory loss, and even coma. It is vital to stay with the victim to ensure they are breathing and stabilise them, if necessary, with emergency procedures before transporting.

Conclusion

By knowing how to administer proper first aid for electrical injuries, you can save the life of a person who has been the victim of an electrical accident. However, never attempt to move a person who has been injured by electrical shock unless you believe they are in imminent danger.
