Information on Purchasing Intrinsically Safe Radios

Be sure to tell your Air Comm rep that you want the "intrinsically safe" option (a.k.a, HazLoc certified option).
“Intrinsically Safe” is an equipment design protection method for Division 1 (see chart below) which encompasses hazards that may be present under normal operating conditions or frequently present during maintenance and repair work.
Radios must include intrinsically safe (UL TIA-4950) battery option. Otherwise, HazLoc certification is not valid.
Motorola has adapted a new TIA-4950 standard for Hazardous Location certification of two-way radios, which is similar to the old FM3610_88 standard. Testing is done by UL (Underwriters Laboratories).
A radio’s HazLoc designation is based on a combination of three area: Class, Division, and Group. Below is a breakdown on the classification system.

Class	Nature of Hazardous Material	Industry Examples
Class I	Flammable gases, liquids, or vapors.	Oil & Gas Industry Dry Cleaning Plants
Class II	Combustible dust.	Plants Using Aluminum / Magnesium / Coal Producers of Chemicals / Medicines Food Industry (Starch / Grain Processing)
Class III	Ignitable fibers and flyings.	Saw Mills / Textile Mills / Flax Processing Plants

Division	Probability of Hazardous Material
Division I	The substance referred to by one of the classes above has a high probability to generate an explosive or ignited mixture under normal operation.
Division II	The substance referred to by one of the classes above has a low probability to generate an explosive or ignited mixture under normal operation and is present only during abnormal conditions.

Group	Type of Hazardous Material
Group A	Acetylene and corresponding gas groups.
Group B	Hydrogen and corresponding gas groups.
Group C	Ethylene and corresponding gas groups.
Group D	Methane and corresponding gas groups.
Group E	Conductive dust, produced via mechanical means such as in factories or through the recycling process.
Group F	Combustible carbon dust, this applies to above-ground applications only and examples include coke dust and charcoal.
Group G	Combustible dust not included in Group E or F, such as flour, grain, starch, sugar, wood, plastics and chemicals.
