Ensuring electrical safety in the construction industry is paramount to safeguarding workers from potential injuries or fatalities. Gain insights into effectively managing electrical risks on construction sites, meeting legal obligations, and fostering a secure environment for yourself and your colleagues.
Understanding the construction industry The construction industry encompasses services involving construction, installation, renovation, as well as the maintenance and repair of buildings and other structures.
Identifying electrical safety risks in the construction industry Exposure to electrical hazards within construction sites can lead to severe injuries or fatalities.
Common hazards include:
- Poorly installed or maintained construction wiring.
- Working in proximity to overhead and underground powerlines.
- Unsafe and inadequately maintained electrical equipment.
- Engaging in energized electrical work or working near energized parts.
Factors contributing to high electrical risk on construction sites:
- Work taking place in and around buildings, exposed to various weather conditions.
- Electrical supply often relying on extension leads, Electrical Portable Outlet Devices (EPODs), construction wiring, and construction switchboards, elevating the risk of cable and equipment damage.
- Breaches of exclusion zones around overhead and underground powerlines.
- Dynamic work environments with a constantly changing workforce.
Construction wiring overview Construction wiring serves as a temporary power supply for construction sites, incorporating:
- Consumer mains and sub-mains supplying construction switchboards, sheds, and amenities.
- Final sub-circuits connected to power points, lighting, and construction plant and equipment.
Electrical supply to construction sites may involve:
- An electricity distributor's primary supply.
- An existing switchboard in the permanent installation of the premises.
- A low-voltage generator.
Typically, construction wiring is removed upon completion of the work.
