Every year in the United States, workplace electrical incidents result in more than 300 deaths and 3,500 injuries.  While electrical hazards are not the leading cause of on-the-job injuries and fatalities, they are disproportionately fatal and costly.  For every 13 electrical injuries, a worker dies.   Knowing best practices of electrical safety are critical to reducing these staggering statistics because most of these injuries could be prevented. 

Electricity and electrical products play a fundamental role in how we conduct business every day. However, if not used or maintained appropriately, they can pose serious risks. Over the last ten years, more than 30,000 workers have been injured in workplace electrical accidents. These injuries not only disrupt the lives of the workers and their families, but also impact the productivity of employers. 

An arc flash is a sudden release of electrical energy through the air when a high-voltage gap exists and there is a breakdown between conductors. An arc flash gives off thermal radiation (heat) and bright, intense light that can cause burns and other injuries. Exposure to extreme temperatures burns the skin directly and ignites the clothing that the worker is wearing. 

An arc flash can be spontaneous, or can result from inadvertently bridging electrical contacts with a conducting object. Other causes may include dropped tools, the buildup of conductive dust, or corrosion. While great advances are being made to improve equipment design and thereby reduce the number of arc flash incidences, there is still much to be done. Each year, 2,000 workers are admitted to burn centers for treatment of severe arc flash burns. 

High-voltage arcs can also produce considerable pressure waves by rapidly heating the air and creating a blast. This pressure burst, or arc blast, can hit a worker with grenade-like force and send metal droplets from melted copper and aluminum electrical components shooting out at speeds up to 700 miles per hour – fast enough for the tiny shrapnel to penetrate ones body.  

Here are some important ways to prevent injuries and fatalities when working with electricity:

Every year, workers are injured or killed by circuits they thought were safely turned off. Simply shutting off the power is not enough. Hazardous conditions can still exist. You may not get a second chance to learn this important lesson, so always test before you touch! 

Most electrically-related fatalities and injuries could easily be avoided. Responsibility for your safety begins with you. Take steps to protect yourself everyday and make safety an integral part of how you do business.
