Construction sites are a hub of activity, with workers and machines constantly on the move to complete various tasks. While construction is necessary for developing infrastructure, it’s essential for workers to be aware of the hazards that come with it. Among the most significant risks on construction sites are electrical hazards, which can cause serious injuries or even fatalities. Reviewing the various electrical safety hazards to be aware of in construction will help you remain more mindful of safety going forward.
Overhead Power Lines
Overhead power lines pose a significant risk to workers on construction sites. Workers who come into contact with live electrical wires can receive a severe electrical shock or even be electrocuted. Danger can also arise if construction equipment comes into contact with electrical wires. To prevent accidents, it’s essential to identify and mark any overhead power lines that may be in the area. Workers should also be trained to maintain a safe distance from these lines and use specialized equipment when necessary. When working near overhead power lines, it’s important to remember that electricity can jump or “arc” through the air if an object gets too close, as we will discuss in the next section.
Arc Flash
An arc flash is a sudden release of energy caused by an electric arc, which can occur when there is a fault in an electrical circuit. Arc flashes can cause severe burns, hearing damage, and even death. As such, it is crucial that professionals who work in the construction industry understand the importance of arc flash mitigation techniques. Operators who work with electrical equipment must wear special clothing and personal protective equipment (PPE) designed to protect them from arc flashes. Maintaining and regularly inspecting all electrical equipment will also help minimize the risk of an arc flash occurring.
Electrical Burns
Electrical burns are perhaps the most common electrical safety hazard to be aware of in construction. Electrical burns are often caused by coming into contact with exposed wiring or electrical equipment. Electrical burns can range from mild to severe, depending on the voltage and current involved. It’s essential that you treat electrical burns immediately by removing the worker from the source of electricity, extinguishing any flames, and administering first aid. Workers can reduce the risk of electrical burns by wearing PPE and avoiding direct contact with electrical equipment.
Faulty Wiring
Faulty wiring is a leading cause of electrical fires and accidents on construction sites, and it is most commonly encountered by crews working on existing structures. Poorly installed or maintained wiring can lead to short circuits, electrical shocks, and other hazards. It’s imperative that you perform regular inspections of all electrical wiring and equipment to identify any potential faults or defects. Workers should also be trained to recognize the signs of faulty wiring, such as flickering lights or tripped breakers, and report any issues immediately.
