#5 Electrical – Top OSHA Violations of 2013

#5 Electrical – Top OSHA Violations of 2013

#5 Electrical  - Part of the Top 10 Most Frequently Cited Standards for Fiscal 2013 Series

Whether you are working as an electrician or in the food industry, electrical hazards have been causing serious injury and fatalities. Electricity is a serious workplace hazard that can cause electrical burns and electrocution. The general industry regulation, 1910.305, was responsible for 3,452 violations in 2013, making this regulation the fifth most likely one for employers to get cited on. The citations for this regulation have double since 2012 (1,744).

If you do not know these wiring regulations please familiarize yourself with it to ensure your business and employees are wiring correctly.

Wiring Methods

Grounding conductors need to be effectively bonded where necessary to ensure electrical continuity and the capacity to conduct safely. Any nonconductive paint, enamel, or similar coating needs to be removed at the threads, contact points, and contact surfaces or be connected by means of fittings designed to make such removal unnecessary. Never install wiring systems of any type where ducts are used to transport dust, loose stock, or flammable vapors. No wiring systems should be installed in a duct that is used for vapor removal or the ventilation of commercial-type cooking equipment.

Temporary Wiring

Temporary electrical installations of more than 600 volts are only feasible to use during periods of tests, experiments, emergencies, or other construction-like activities. Temporary electrical power and lighting installations of 600 volts or less may be used only as the following:

  • During and for remodeling, maintenance, or the repair of buildings, structures, or equipment
  • For Christmas decorative lighting, carnivals, and similar purposes for a period of time that doesn’t exceed 90 days
  • For experimental or development work, and during emergencies

Temporary wiring needs to be removed immediately when the project or purpose of the wiring is completed.

Cabinets, boxes and fittings

It is important to protect conductors that enter cutout boxes, cabinets, or fittings from abrasion. Make sure to keep openings where conductors enter and are unused, closed. Secure the cables to the cabinet, cutout box, or meter socket.

Where entirely nonmetallic, sheathed cables enters the top of a surface-mounted enclosure through one or more nonflexible raceways at least 18 in. or more than 10 ft. long, the cable doesn’t have to be secured as long as it meets the following conditions:

  • Cables fastened within 12 in. of the outer end of the raceway
  • The raceway extends directly above the enclosure and doesn’t penetrate a structural ceiling
  • A fitting is provided at each end of the raceway to protect the cable from abrasion
  • The fittings remain accessible
  • The raceway is sealed or plugged at the outer end, preventing access to the enclosure
  • The cable sheath is continuous through the raceway and goes into the enclose at least 0.25 in. beyond the fitting
  • The raceway is fastened at its outer end and at other points where needed

Conductors for General Wiring

All conductors used for general wiring must be insulated, unless it is otherwise permitted. Insulated conductors approved for the voltage, operating temperature and location is the default requirement for conductors in general wiring. They also need to be distinguishable as grounded, ungrounded or equipment grounding conductors.

These are just little parts of this regulation. There is much more to wiring and electrical that can be found at www.osha.gov.
