M88 Nonincendive Handheld VHF RadioWhat 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
