Proper training of the operations of equipment as well as how to prevent an arc flash can help reduce the risk. Many arc flash incidents are preventable and the result of human error. Loose connections or missing insulation are common reasons for arc flash incidents that can be prevented with proper maintenance.Ĥ. Performing proper electrical maintenance and routine inspections such as infrared inspections and tightening of lugs helps prevent arc flash incidents from happening. Remote racking of breakers can be done with robotics and remove the worker from the arc flash boundary to eliminate injury, but it doesn’t prevent an arc flash from occurring.ģ. Installing electrical equipment or devices that reduce the fault clearing time.Ģ.Install or replace fuses or breakers that reduce the available fault current. ![]() Mitigating or reducing the the arc flash risk is often done after the arc flash risk assessment including:.There are a few ways we can limit the arc flash hazards: There is no way to completely prevent an arc flash from happening. ![]()
