In addition to the workplace hazards generally faced by industrial workers, electricians are also particularly exposed to injury by electricity.
An electrician may experience electric shock due to direct contact with energized circuit conductors or due to stray voltage caused by faults in a system.An electric arc exposes eyes and skin to hazardous amounts of heat and light. Faulty switchgear may cause an arc flash incident with a resultant blast. Electricians are trained to work safely and take many measures to minimize the danger of injury. Lockout and tagout procedures are used to make sure that circuits are proven to be de-energized before work is done.
