Course Description
The inadequate electrical installation often resulted in fires, and standard installation methods did not exist. In recent years, the community has begun to recognize that in addition to fire and electrocution, arc-flash and arc-blast hazards also result in injury. The knowledge base about these hazards is expanding but is not yet complete. The community knows that as the distance between a worker and an electrical hazard decreases the degree of exposure increases.
Employees must understand that they are exposed to these hazards until an electrically safe work condition has been established, as explained in this workshop. Recently, the electrical community has begun to understand that workers are exposed to many different electrical hazards. Workers certainly should not be unnecessarily exposed to hazards. Workers should understand how and when they could be exposed to a hazard and how to assess the hazard and risk of injury. They must also understand how to select and use work practices that minimize or eliminate the risk of injury and how to select and wear protective equipment that will minimize or eliminate that risk.
Basic Arc Flash hazard course provides front-line electrical workers with the information they need to make safe decisions involving their work practices. From this training, they will receive the proper awareness and training needed in order to develop a personal arc flash safety strategy in the workplace. This 5 days seminar will go in-depth with arc flash hazard analysis using commercial worldwide software like ETAP power station from OTI.
