This Technical Report provides guidance on the safe use of fiber optic systems and their constituent parts producing or guiding visible, near infrared, or mid infrared (maximum wavelength of 10 micrometers) radiation in Class I hazardous (classified) locations. Hazardous (classified) locations are described in the National Electrical Code (NEC). Limiting levels prescribed in this document apply only to the minimum levels of optical power, optical power density, and optical energy needed to ignite explosive gas atmospheres. In apparatus where optical energy is transduced to electrical energy, the limiting values for the electrical energy must be determined from relevant standards for electrical apparatus (e.g. ANSI/ISA-12.00.01).
