Wikipedia about protection in electrical industry
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.
Limits of approach to energized equipment protect against arc flash exposure; specially designed flash-resistant clothing provides additional protection; grounding (earthing) clamps and chains are used on line conductors to provide a visible assurance that a conductor is de-energized.
Personal protective equipment provides electrical insulation as well as protection from mechanical impact; gloves have insulating rubber liners, and work boots and hard hats are specially rated to provide protection from shock.
If a system cannot be de-energized, insulated tools are used; even high-voltage transmission lines can be repaired while energized, when necessary.
Electrical workers, which includes electricians, accounted for 34% of total electrocutions of construction trades workers in the United States between 1992?2003.Źródło: https://en.wikipedia.org/wiki/Electrician
Electrician - high-risk profession? Occupation electrician is very often seen as a profession in which extremely common ones are physical injury. This is related primarily to the fact that when working with electricity, even the smallest mistake can cause severe short circuit, which would be harmful to human health.
Usually created a power failure is unexpected and electrician seeking a solution to the problem moves groping.
Therefore, for such a mistake it is very easy and you can tell that no theoretical knowledge is not able to prepare the employee to perfect the profession, because of some random events can not be predicted.
Car workshops multitasking
Very often we meet with automotive workshops that offer electrical services.
They belong to the same frequently used services, such as services varnishing or mechanics.
As you know, a major failure associated with electricity in the car can lead to significant deficiencies and prevent the smooth functioning of the car.
Therefore, many people use the services of electricians employed in garages.
You could say that as a specialty electrician person working in the garage is very much needed, because the newer the car, the more it solutions for electrical and electronics, and you need a particular specialist, to effectively remove the fault..
