Hazardous Area Zones Classification
Zone 1 - where flammable atmosphere is likely to occur during normal operation.
Zone 2 - where flammable atmosphere is not likely to occur during normal operation and if it does will only exist for short period of time, typically less than 10 hours per year.
Zone 21 - a place in which an explosive atmosphere, in the form of a cloud of combustible dust in air, is likely to occur occasionally in normal operation.
Zone 22 - a place in which an explosive atmosphere, in the form of a cloud of combustible dust in air, is likely to occur in normal operation but, if it does occur, will persist only for a short period.
ATEX Certified Electrical Equipment for Hazardous Areas
ATEX is the name given to a set of European Directives relating to Hazardous Area Electrical Equipment Installations (Flammable Atmospheres) to avoid industrial accident or incident. ATEX Directive 94/9/EC (ATEX 95), is a directive adopted by the EU under the “New Approach” strategy.
The “New Approach” ATEX directive supersedes the “Old Approach” ATEX Directive, the Potentially Explosive Atmospheres Directive, 76/117/EEC – ATEX 94/9/EC (ATEX 95) facilitates free trade in the EC for hazardous area electrical equipment intended to be used in potentially explosive atmospheres. ATEX Directive 94/9/EC (ATEX 95) covers “Electrical Equipment” used in hazardous areas with potentially explosive atmospheres created by presence of gases, vapours, mists or dusts. T&D UK stock and distribute an extensive range of ATEX Certified Electrical Equipment for Hazardous Areas including fused disconnectors, power switches, changeover switches, cable glands, motor starters, electrical enclosures, junction boxes, plugs and sockets, cable joints, control stations, cable transits, cable cleats, mobile phones, laptops, digital cameras, conduit systems, portable lighting (torches, handlamps, headlamps).
