When you’re operating in environments where flammable or explosive gases, vapors or dust may be present, you should consider communications equipment Certified for use in a Hazardous Location – often called “HazLoc”.
The established Factory Mutual standard FM3610_88 expired in 2012. Radios certified to FM3610_88 will be phased out of production in December 2015. Motorola will be adapting to a new TIA-4950 standard for Hazardous Location certification of two-way radios, which is similar to the FM3610_88 standard. Compliance testing will be done by UL (Underwriters Laboratories).
