The BlueEye™ Ex-D enclosure is epoxy coated. Under certain extreme conditions it may generate an ignition-
capable level of electrostatic charges.
- DO ensure that the equipment is NOT installed in a location where it may be subjected to
external conditions (such as high-pressure steam) which might cause a build-up of
electrostatic charges on non-conducting surfaces.
1.4 Certification for hazardous areas
Hazardous area classifications:
• Zone 0: An area classified as Zone 0 will have ignitable concentrations of flammable gases, vapours
or liquids either continuously present or present for long periods of time under normal operating
conditions.
• Zone 1: An area classified as Zone 1 is likely to have ignitable concentrations of flammable gases,
vapours or liquids present under normal operating conditions. Flameproof (Exd) detectors are suitable
for use in Zone 1.
• Zone 2: An area classified as Zone 2 is not likely to have ignitable concentrations of flammable gases,
vapours or liquids present under normal operating conditions. Flameproof (Exd) detectors are suitable
for use in Zone 2.
• Areas that may contain flammable dusts are categorized as Zone, 20, Zone 21 and Zone 22.
