The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States.
In addition to the workplace hazards generally faced by industrial workers, electricians are also particularly exposed to injury by electricity.
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
It is very important to install the appropriate wiring to the building during the operation met its functions.Therefore, this electrician is responsible for the oversight of electricity on site and very often his help is invaluable, because it allows the reception of installations, without which the building does not meet the required functions..
