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.
