Two NFPA documents have changed infrared thermography over the last two decades: NFPA 70B and NFPA 70E. NFPA 70B is the Recommended Practice for Electrical Equipment Maintenance, and 70E is the standard that covers electrical safety in the workplace.Infrared Inspections of electrical equipment identify excess heat on electrical apparatus and detect electrical issues such as loose connections, faulty fuses, defective breakers, damaged switches, overloaded or imbalanced circuits and a myriad of other problematic electrical conditions. Maintenance personnel utilize Thermography as part of a comprehensive Predictive, Preventive and Proactive Maintenance Program. Minimizing damage to electrical systems, addressing and correcting potential safety and operation-stopping hazards prevents downtime, saves money and protects employees. No one would disagree that no other organization in the United States or truly in the world as had a greater impact on infrared thermography over the last 25 years than the NFPA with the production of these two documents.
Specifically concerning electrical maintenance, an excerpt from the NFPA 70B declares, “a well-administered Electrical Preventative Maintenance program will reduce accidents, save lives, and minimize costly break downs and unplanned shutdowns of production equipment.” 70B further recommends “routine infrared inspections of energized electrical systems should be performed annually prior to shutdown. More frequent infrared inspections, for example, quarterly or semi-annually, should be performed where warranted by loss experience, installation of new electrical equipment, or changes in environmental, operational, or load conditions.”
Although NFPA has no regulatory power, their recommendations were given legitimacy when they were adopted as a standard by the Occupational Health and Safety Administration (OSHA), the main US government agency responsible for the enforcement of safety and health legislation in American industry. OSHA has the power and the authority to levy substantial fines on businesses that do not conform to their authored or adopted standards
