What does OSHA require for extension cords used in the workplace?

The requirement that OSHA has for extension cords in the workplace is that they must be three-wire cords. This design includes a grounding wire, which is essential for worker safety. The three-wire system connects to a grounded electrical outlet, reducing the risk of electrical shock. This standard helps ensure that the equipment being powered is safe for use in potentially hazardous environments.

Using only two-wire cords can expose workers to increased risks, especially in environments where water or other conductive materials are present. OSHA emphasizes the importance of proper grounding and safe electrical practices, which is why the three-wire configuration is mandated.

Regarding the other options, while flat cords may be used in specific situations, they are not a requirement, nor are they inherently safer than round cords. Color-coding is not a specific OSHA requirement for extension cords; it may be used for purposes of organization but does not impact safety in the same way that grounding does. Additionally, there is no maximum length of 50 feet specified by OSHA; the length of an extension cord should consider the electrical load and the conditions of use rather than adhering to a strict limit.
