Which of the following statements is true regarding the working distance parameter for PPE selection?

The working distance parameter is a critical factor in the selection of personal protective equipment (PPE) because it directly relates to the potential arc flash risk an employee may encounter. The main purpose of determining this distance is to ensure that the PPE selected will adequately protect the worker from potential electrical hazards, specifically arc flash incidents, at that distance.

When the working distance parameter value is established, the associated arc flash incident energy levels can be identified. Therefore, for effective protection, the actual working distance must be less than or equal to this parameter. This ensures that the PPE being used can provide the necessary protection against the potential incident energy levels identified at that specific distance.

By choosing PPE based on a working distance that meets this requirement, workers can ensure they are adequately safeguarded from electrical hazards during their tasks. This aspect is crucial in electric safety practices as it encompasses both risk assessment and appropriate equipment selection, ensuring compliance with safety standards such as those outlined in NFPA 70E.

In contrast, the other statements do not accurately reflect the role of working distance in PPE selection. For instance, claiming that it is not a factor in PPE selection fails to recognize its importance in evaluating potential exposure risks. Likewise, asserting that it requires no specific measurement overlooks the necessity
