NFPA 70E Electrical Safety Summary

Number 263 View Entire Article

Personal Protective Clothing Ratings

Building an electrical safety Personal Protective Equipment (PPE) list for workers begins with selecting the right clothing. Flame retardant clothing is assigned an ATPV rating by the manufacturer. The ATPV value represents the amount of incident energy that would cause the onset of second-degree burns. It also signifies the amount of protection the clothing provides when an electrical arc comes in contact with the fabric.

Most people working with electricity only require clothing that meets Category 1 or 2 protection characteristics. NFPA 70E standards are aimed more towards those workers who work in Category 3 or 4 hazard situations. Their clothing must meet APTV rating minimums throughout the life of the garment. In other words, each piece of clothing must also be designed to withstand a cleaning process to remove soils and then be returned to service without damage to the fabric.

** To obtain all the clothing options available that meet the NFPA 70E Standard, or if you have any other questions regarding protective clothing please contact Lab Safety Supply's Technical Department at 1-800-356-2501 or via e-mail at techsvc@labsafety.com. We carry a complete line of garments that meet each risk category of this standard.

There are several sources that can help make sure you purchase clothing that meets your hazard category APTV levels beginning with the label of the garment itself. To meet OSHA regulations and NFPA 70E, the label on the garment must contain the following information: tracking ID number, meet ASTM spec F1506, name of manufacturer, size and care instructions, ATPV rating, and must meet ASTM spec F1506.

For help determining what PPE to use based on the risk factors in your workplace, there is a website that utilizes an arc calculator to help determine what PPE to use. There is a fee charged for the use of this calculator. It can be found at www.arcadvisor.com. Lab Safety Supply is not affiliated with www.arcadvisor.com and is referring to this website as a reference only.
