Craig & Derricott ATEX Zone 22 Certified Isolators
From July 2006 the onus was placed upon companies to ensure that all electrical equipment within their site organisation is suitable for the environment in which it is being used - this was aimed particularly at hazardous areas where there may be a possibility of a combustible atmosphere being present, even for short periods i.e. less than 10 hours/year.

People normally think of such atmospheres as being gases, mists or vapours - however there are various industries where a conductive or non-conductive dust mixed with air in the right proportion can become explosive.

There are different degrees of protection against explosive dusts and hazardous area Zone 22 is defined as : - "a place in which an explosive atmosphere, in the form of a cloud of combustible dust in air, is not likely to occur in normal operation but, if it does occur, will persist for a short period only".

ATEX Directive 94/9/EC sets out the route electrical equipment manufacturers must take to get their products certified for use in hazardous areas. 

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.
