Intrinsic safety is only met when used with the approved radio models,
approved accessories and options. Check your radio for the intrinsically
safe label. The label will identify the rating to be used with your approved
portable unit.

For reasons of liability, we cannot advise our customers what ratings
of radio equipment they would need for their work environment.
They would need to research it themselves.
