Sepura will introduce at the Tetra World Congress 2011 intrinsically safe products to its line of TETRA radios.

The STP8X is an IP67 submersible TETRA radio designed to meet ATEX and IECEx robustness tests. The radio features missed-event notifications, a Micro-SD image viewer, and Man-Down application — capable of indentifying when a user has become incapacitated, notifying rescue crews via TETRA and sounding a local alarm.
