What additional protection against electric shock is required by OSHA on construction jobs?

Ground fault circuit interrupters (GFCIs) provide essential protection against electric shock, particularly in construction settings where the risk of encountering wet conditions is heightened. GFCIs are designed to disconnect the electrical circuit whenever they detect an imbalance in the electrical current, which could indicate that electricity is flowing through an unintended path, such as through a person who is grounded. This rapid disconnection can significantly reduce the likelihood of serious injury or fatality due to electrocution.

OSHA requires GFCIs to be used on construction sites to ensure worker safety, especially in areas where personnel may be exposed to moisture or conductive materials. By implementing GFCIs, the risk of electrical shock is thereby minimized, safeguarding workers while they perform their tasks.

Other options, while they have their respective applications in electrical safety, do not provide the specific protection required by OSHA in this context. Double insulation is a design feature for electrical devices that prevents user contact with live parts, and automatic circuit breakers serve to break the circuit in the event of an overload but do not specifically protect against ground faults. Surge protectors are intended to protect equipment from voltage spikes but do not offer direct electric shock protection. Thus, GFCIs are the most suitable and effective choice for additional protection against
