M88 Nonincendive Handheld VHF Radio

What makes Icom's M88 so special? Functionality. Features. Unparalleled battery life and power. Submersible construction. Military ruggedness. Frequency control. Choice of optional features. And a surprisingly small size that fits incredibly well in the hand. Compare for yourself; the Icom IC-M88 is a better fit not just for one-handed operation, but all-around.

What is nonincendive equipment? Section 500.7(F) of the National Electrical Code explains that it is a protection technique for equipment used in Class I, Division 2, hazardous (classified) locations.

Intrinsically Safe vs. Nonincendive

• A radio termed "intrinsically safe" is designed and certified to
  eliminate or encapsulate any components that produce sparks or which
  could generate enough heat to cause an ignition in areas with flammable
  gasses, dusts or fuels. Most of these radios are approved to sell in
  Division 1 & 2
  
• Nonincendive radios are incapable of generating thermal or
  electrical energy sufficient to ignite a volatile atmosphere under normal
  operating conditions-although sufficient energy for ignition could be
  generated under fault conditions. These radios are only approved to sell
  in Division 2
  
• Division 1 = hazardous locations such as inside a tank or container
  requires "intrinsically safe" equipment
  
• Division 2 = hazardous locations such as outside of the shielded
  tank or container requires "nonincendive" equipment
