Which of the following information is not required to be on the arc flash label per NFPA 70E?

The correct choice highlights that the date is not a required piece of information to be included on an arc flash label as per NFPA 70E. The purpose of the arc flash label is to provide essential safety information to workers who may be exposed to electrical hazards.

The energy level is crucial because it indicates the potential severity of an arc flash incident, allowing employees to understand the risks associated with working on or near electrical equipment. Required PPE (Personal Protective Equipment) is specified to ensure workers are adequately protected based on the calculated risk of exposure to arc flash hazards. The flash boundary delineates the distance at which a person could receive a second-degree burn from an arc flash, serving as a critical safety guide.

While maintaining accurate information about the date might be useful in certain contexts, such as documenting when the evaluation was performed or when the label was created, it is not mandated by NFPA 70E as a requirement on the label itself. Therefore, the absence of the date from the arc flash label is appropriate as it does not affect the immediate understanding of the safety precautions needed for electrical work.
