Operating electrical tools without proper safeguards in place at the construction site can lead to various hazards.
According to the Occupational Safety and Health Administration (OSHA), electrocution is one of the construction industry’s “Fatal Four.” Implement the following guidance to ensure electrical safety at the construction site.
Tool and Cord Selection
Be sure to provide electrical tools that are double-insulated or have a ground pin. Double-insulated tools are typically encased in plastic, which can help prevent the operator from experiencing electric shock if the tool develops a short circuit. Tools with a ground pin can redirect an electrical current and trip the circuit breaker if the tool overloads or malfunctions, minimizing the risk of fires or electrocution taking place.
When selecting extension cords, take note that OSHA requires construction employers to utilize three-wire, three-prong cords designed for hard or extra-hard usage. Further, instruct employees to inspect tools and cords before each use. Conduct maintenance and repairs to these items as needed. Never allow staff to use damaged tools or cords.
GFCIs and AEGCPs
Ground-fault circuit interrupters (GFCIs) are fast-acting circuit breakers that can quickly shut off power in the event that damaged wiring or tools create electrical hazards. It’s important to use GFCIs whenever the circuit is not part of the permanent wiring of the building or structure on-site.
As an alternative to using GFCIs, you can implement an assured equipment grounding conductor program (AEGCP) at the construction site. AEGCPs ensure all grounding wires are electrically continuous from the tool to the power source. An AEGCP typically consists of a written program, daily inspections and routine electrical equipment testing.
