The MTP8550Ex in the field
How the MTP8550Ex meets the constraints of sites with explosive atmospheres in Côte d'Ivoire and across West Africa.
- 01 Context On a refining platform or at a gas terminal, operators work in units where hydrocarbon vapours may be present.
- 02 Challenge A standard electronic device can cause a spark or a hot spot: it is prohibited in these zones.
- 03 Response The MTP8550Ex is certified for zones 1 and 21, including group IIC gases. Its fall alert and priority emergency call notify dispatch if an operator stops responding.
- 04 Result Teams reachable on the TETRA network with equipment compliant with the zone. For zone 0 or 20, a specific study is required.
