Electricians, like any trade professional, must complete several training programs to learn the ropes and ultimately earn certification. However, no matter how extensive, their learning is never officially complete. Thanks to advancements in technology, as well as the evolution of industry techniques and standards, professionals must continue their education every few years.
One form of training that must be updated is that of electrical hazards such as shocks and arc flash events. According to OSHA and NFPA 70E, electricians must retrain every three years, at the least.
