Intrinsically Safe Radio Information
The Intrinsically safe approval unit refers to a product that has been approved as intrinsically safe by an approval agency (for
example FM Approvals, CSA, UL, or Cenelec) and certifies that a particular product meets the Agency's applicable intrinsic safety
standards for specific types of hazardous classified locations. A portable radio that has been approved for intrinsic safety will have
Approval label attached to the radio to identify the unit as being approved for specified hazardous atmospheres. This label specifies
the hazardous Class/Division/Group along with the part number of the battery that must be used. The Intrinsically Safe Approval
Label will be located on the portable radio unit.
Operational Cautions for Intrinsic Safe Equipment
Warnings for Radios Approved as Intrinsically Safe
Radios must ship from the Unication manufacturing facility with the hazardous atmosphere capability and the intrinsic safety
approval labeling (FM, UL, CSA, CENELEC). Radios will not be upgraded to this capability and labeled once they have been
shipped to the field.
A modification changes the unit’s hardware from its original design configuration.
Modifications can only be made by the original product manufacturer.
• Do not operate radio communications equipment in a hazardous atmosphere unless it is a type especially
qualified (for example, FM, UL, CSA, or CENELEC approved). An explosion or fire may result.
• Do not operate a radio unit that has been approved as intrinsically safe product in a hazardous atmosphere if
it has been physically damaged (for example, cracked housing). An explosion or fire may result.
• Do not replace or charge batteries in a hazardous atmosphere. Contact sparking may occur while installing
or removing batteries and cause an explosion or fire.
• Do not replace or change accessories in a hazardous atmosphere. Contact sparking may occur while
installing or removing accessories and cause an explosion or fire.
• Turn the radio off before removing or installing a battery or accessory.
• Do not disassemble an intrinsically safe product in any way that exposes the internal circuits of the unit.
• Failure to use an intrinsically safe approved battery or Approved accessories specifically approved for the
radio unit may result in the dangerously unsafe condition of an unapproved radio combination being used in
a hazardous location.
• Unauthorized or incorrect modification of the intrinsically safe approved Product will negate the approval
rating of the product.
• Incorrect repair or relabeling of any intrinsically safe Agency approved radio could adversely affect the
Approval rating of the unit.
• Use of a radio that is not intrinsically safe in a hazardous atmosphere could result in serious injury or death.
