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, CENELEC or ATEX) 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
• Do not operate radio communications equipment in a hazardous atmosphere unless it is a type
especially qualified (for example, FM, UL, CSA, or CENELEC or ATEX 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.
Operational Cautions for Intrinsic Safe Equipment
Radios must ship from the Motorola manufacturing facility with the hazardous atmosphere capability
and the intrinsic safety approval labelling (FM, UL, CSA, CENELEC or ATEX). 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 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.
