What does NFPA 70E Informative Annex M relate to?

Informative Annex M in NFPA 70E specifically addresses the layering of protective clothing. Layering is a critical concept when it comes to personal protective equipment (PPE) for electrical safety. It provides guidance on how to combine various types of clothing and fabrics to enhance protection without sacrificing comfort and mobility. The emphasis on layering helps ensure that workers are adequately protected from arc flash hazards while also considering practical aspects such as breathability and moisture control.

Layering allows for an effective strategy to achieve the appropriate level of protection, as different fabrics have varying thermal protective qualities. This promotes not only safety in high-risk environments where electrical work occurs but also allows for flexibility in adapting to different working conditions. Understanding the principles outlined in Annex M helps to make informed decisions about selecting and using protective clothing effectively, ensuring that employees adhere to safety standards while minimizing the risk of injury.
