Some fact about electrinians
An electrician is a tradesperson specializing in electrical wiring of buildings, stationary machines. and related equipment. Electricians may be employed in the installation of new electrical components or the maintenance and repair of existing electrical infrastructure. Electricians may also specialize in wiring ships, airplanes, and other mobile platforms, as well as data and cable.
Competency standards in the UK are defined by the Sector Skills council Summit Skills. Qualifications certificated by awarding organisations such as City and Guilds and EAL are based on these National Occupational Standards. Once qualified and demonstrating the required level of competence an Electrician can register with the JIB (Joint industry Board) for an Electrotechnical Certification Scheme (ECS) card. Electrical competence is required at Level 3 to practice as an electrician in the UK. The electrical industry is one of the few that require a trade test to be achieved prior to being fully qualified. This is known as the AM2.
Electricians can demonstrate further competence by studying further qualifications in Design and Verification of Electrical Installations or in the Test and Inspection of Electrical Installations. These qualifications can be listed on the reverse of the JIB card.
The Electricity at Work Regulations are the statutory document that covers electrical installations. Further information is provided in the non-statutory document BS7671 - Requirements for Electrical Installations otherwise known as the Wiring Regulations currently (2013) in their 17th Edition. Installations that comply with BS7671 are deemed to have met the EAWR. Electrical Installation in domestic properties is governed by Part P of the Building Regulations and electricians have to register certain aspects of their work in domestic properties with the local building control authority.
With the exception of the work described in Part P of the Building Regulations there are no laws that prevent anyone from carrying out electrical work in the UK. A possible result of this is that during 2010/11 and in 2011/12 there were 3,822 domestic electrical fires in Great Britain, resulting in 14 deaths. Organisations such as the Electrical Safety Council are working hard to educate the public not to use electricians who are not fully qualified or competent and to check the ElectricSafe register to ensure an Electrician has been deemed competent.
First thing - safety
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.
Basic safety rules during contact with electricity are well known. However, in the case of a work such as electrical work daily contact with dangerous voltages may cause the vigilance of the employee is asleep. When an employee falls into a rut during the execution of orders, its security is threatened, and much easier for the accident. First of all, it is important to adequately protect the body from exposure to electricity. In addition, when touching the cables should always be touching the outer side of the hand, where possible, of course, since the shock hand grips on a same line and this may lead to disaster. It is worth remembering these basic principles.
