Construction – Electrical Safety Electricity is an essential source of energy for most work-related operations. However, fewer sources have a greater potential to cause harm than electricity. Working safely with electricity is possible if you are trained in, understand, and follow certain basic ground rules. It doesn’t take a lot...
Arc Flash Safety Simply put, an arc flash is a phenomenon where a flashover of electric current leaves its intended path and travels through the air from one conductor to another or to ground. The results are often violent and when a human is in close proximity to the arc...

Ground-Fault Circuit-Interrupters (GFCI) The most common electric shock hazard, ground faults, can cause severe electrical shock or electrocution. In normal conditions, electricity runs in a closed circuit; electricity flows out on the “hot” wire and returns on the “neutral” wire, completing the circuit. A ground fault occurs when the electrical...
Ground-Fault Circuit-Interrupters (GFCI) A ground fault occurs when the electrical current does not complete its circuit and unintentionally flows to the ground. Ground faults can cause fires and are dangerous when they flow through a person to the ground. The GFCI, as it is commonly called, is simply a fast-acting...
Bonding and Grounding Static electricity is generated by friction or by the quick separation of materials. Walking across a carpet generates static electricity. You can feel the charge as you touch a door handle. The spark produced from this discharge usually contains enough energy to ignite flammable vapors if they...
Bonding and Grounding When transferring flammable liquids, it is important that the containers involved are bonded and grounded in order to prevent static electricity from igniting the vapors. Static electricity results from the interaction of dissimilar materials. This can occur when materials are rubbed together, such as walking across carpet...
Electrical Safety – Overhead Power Lines Electrocution remains a major cause of deaths in construction. Part of the reason is that at home and on the job we take electricity for granted. This can lead to familiarity and a false sense of security. Relying on the benefits of electricity, we...
