NFPA 70E/ Arc Flash Electrical Safety with Introduction to Arc Flash Analysis
Description
A good option to add to our essential two-day NFPA 70E/Arc Flash Electrical Safety course is this additional third-day course: Introduction to Arc Flash Analysis. An arc flash is a pressure wave caused by the rapid expansion of gases and conducting material with high flying molten materials and shrapnel. Due to the extreme hazards of arc flashes while working near energized equipment, electrical safety is critical. This third day teaches the fundamentals of electrical safety as it pertains to NFPA70E standards, including the 2012 updates. OSHA’s mandated training requirements apply to employees who face a risk of electric shock that is not reduced to a safe level by the electrical installation requirements of OSHA 29 CFR 1910.303 through 1910.308. Electrical safety training empowers workers to perform their jobs safely.
