The Supply of Intrinsically Safe (IS) Devices on the Emergency Services Network (ESN)

This Notice is to notify the market that the Emergency Services Mobile Communications Programme (ESMCP) plans to enter into a market engagement exercise to discuss its potential requirements with potential suppliers in the market of provision of intrinsically safe devices such that the Authority may establish a commercial strategy for the supply of its potential requirements. Certain specialist ESN users respond to incidents at locations where there is a risk of explosive atmospheres being present (for example, oil & gas installations). To meet the strict safety regulations at such sites, any ESN devices and accessories used on site must have ATEX zone 1/21 certification. The devices must allow users to make PTT calls and use simple applications, including while wearing PPE. The Authority user requirements call for a A ruggedized Android smartphone with ATEX zone 1/21 certification suitable for use with the ESN PTT application, plus compatible accessories.
