Electrical workers understand that electricity is a powerful and necessary force, but they also know it can be extremely dangerous. One of the less common—but still very real—risks of working with electricity is an arc flash, which can cause severe burns, injuries, and even death. In this guide, we’ll delve into what arc flashes are, how they happen, and, most importantly, how you can avoid them.
An arc flash is a sudden release of electrical energy through the air when there is a fault or short circuit in an electrical system. This can happen when conductors or equipment become damaged, worn out, or overloaded. The result is a bright light and intense heat that can reach temperatures as high as 35,000 degrees Fahrenheit. These high temperatures can instantly vaporize metal components, create loud noises, and produce dangerous pressure waves that can cause severe injury to anyone nearby.
Arc flashes can happen anywhere, but they are more common in industrial environments where high voltage electrical equipment is present. For this reason, it’s important for employers and employees to work together to ensure safe industrial electrical installations. A lack of proper safety measures, training, and maintenance can all increase the risk of arc flashes.
Other factors that can contribute to arc flash incidents include:
In short, any situation that increases the likelihood of an electrical fault occurring also increases the possibility of an arc flash incident.
Now that you know what arc flashes are and why they happen, what can you do to prevent them? Ultimately, you need to take the necessary precautions. Some ways you can protect yourself against arc flashes include:
Don’t let an arc flash occur in your workplace. You have the power to stop this dangerous phenomenon from happening—all you need to do is be knowledgeable, proactive, vigilant, and safe.
