For those of us who utilize NFPA 70, National Electrical Code (NEC) and NFPA 70E, Standard for Electrical Safety in the Workplace, on a regular basis, we know the importance that the NEC plays when it comes to the installation of safe electrical systems and the safe work practices that 70E provides, allowing us to perform those installations and maintenance, safely.
But there’s a third document that’s key to this equation: NFPA 70B, Recommended Practice for Electrical Equipment Maintenance, which covers equipment maintenance. 70B offers guidelines for maintaining equipment after the initial installation is done and regular usage begins to impose wear and tear on the equipment. While each document covers a specific area, by using them together, it helps provide the safest electrical system possible while maintaining a safe working environment for those performing the necessary tasks. For example, NFPA 70B deals with electrical equipment maintenance, the NEC stipulates the installation rules necessary for a proper installation, and NFPA 70E addresses safe work practices needed to help ensure that the installation and maintenance are done safely. When the three are used in concert, and correctly, they provide for a complete electrical safety cycle. When one or more pieces are missing, it may leave the door open to catastrophic accidents—even death.
To help workers navigate this “cycle of safety,” NFPA has developed a new NFPA 70B fact sheet that explains its purpose and highlights its relationship to related codes and standards. It also points out key chapters and the value of an effective electrical preventative maintenance program (EPM).
If you missed last week’s NEC Facebook Live event, you can still catch the video with host Derek Vigstol and two special guests, Jim Dollard and Tom Domitrovich who discussed, “The Electrical Safety Cycle: NFPA 70, NFPA 70E & NFPA 70B.” Visit the NEC Facebook page to see the discussion.
