In NFPA 70E Section 130.4, what must be identified if additional protective measures are required?

In NFPA 70E Section 130.4, if additional protective measures are required, it is essential to identify the design of the electrical equipment. This requirement is linked to the fact that different designs can impact the level of protection needed against arc flash hazards. Understanding the specifics of the electrical equipment design ensures that appropriate hazard assessments are performed and that suitable personal protective equipment (PPE) is selected to mitigate risks effectively.

Additionally, clarity on the design helps in analyzing potential incident energy levels and assessing the specific safety measures necessary for workers operating near or on such equipment. Knowing the design details can facilitate the implementation of adequate protective strategies, contributing to overall workplace safety and compliance with standards.
