- Arc flash hazard boundary
Arc flash is a sudden explosion caused by an electrical system fault that greatly compromises employee safety. During an arc flash event, temperatures can reach as high as 35,000°F, and a dangerous level of energy is released through a powerful explosion. Approximately five to ten arc flashes occur every day in the United States, up to 6% of all fatal occupational injuries are caused from exposure to an arc flash. It’s important to ensure precautions are not overlooked and the appropriate steps are taken to safeguard your electrical system and reduce potential risks. The Occupational Safety and Health Administration (OSHA) requires all employers to access all hazards involved in the workplace, and arc flash hazards are included in this. Section 5(a)(1) of the Occupational Safety and Health Act requires an employer to furnish to its employees: employment and a place of employment, which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to its employees Gettle’s experienced team of arc flash hazard experts are available to help your business identify the arc flash hazards at your facility, determine the appropriate Personnel Protective Equipment (PPE).
