The National Electrical Code (NEC) provides guidelines for safe electrical installations and is widely adopted in the United States. Article 504 of the NEC specifically addresses intrinsically safe systems and their use in hazardous locations. NEC (National Electrical Code) contains guidelines and requirements for the installation and use of electrical systems in hazardous locations. It includes specific rules for intrinsically safe systems, which are designed to prevent ignition of hazardous vapors. NEMA (National Electrical Manufacturers Association) is a trade organization that develops standards for electrical equipment, but it does not have authority in regulating hazardous locations. IEEE (Institute of Electrical and Electronics Engineers) is a professional association for electrical and electronics engineers, but it does not regulate hazardous locations. UL (Underwriters Laboratories) is a certification organization that tests and verifies the safety of electrical equipment, but it does not regulate hazardous locations.
