ATEX DIRECTIVE

There are two EU Directives - ATEX 95 (94/9/EC) and ATEX 137 (1999/92/EC) concerning, respectively, the supply and use of equipment in potentially explosive atmospheres. The term "ATEX" is derived from the French "Atmospheres Explosive".

The user directive, ATEX 137, is implemented by HSE under the Dangerous Substances and Explosive Atmosphere Regulations, 2002 (DSEAR). ATEX 137 concerns worker health and safety and safety in those workplaces where potentially explosive atmosheres may be present.

The ATEX Directive required operators to classify Hazardous areas in plant in a more scientific manner. The chart below indicates approximate Zone equivalents in Canada and the USA as Class 1 Div 1 may be considered as Zone 0 equivalent.

Europe IEC (International)
Zone 1 Zone 1
Zone 2 Zone 2

Area classifications in accordance with the ATEX Directive are designated as:

Zone 0 (Most Hazardous)

Area in which an explosive gas atmosphere is likely to occur in normal operation in excess of 1000 hours/year.

Zone 1

Area in which an explosive gas atmosphere is likely to occur in normal operation occasionally (e.g. 10-1000 hours/year).

Zone 2 (Least Hazardous)

Area in which an explosive gas atmosphere is not likely to occur in normal operation and if it does occur, is likely to do so only infrequently and will exist for a short period only (e.g. less than 10 hours/year). Category I, II and III can be used in Zone 2.

To meet these specifications, SeSys have a range of cameras that are certified for use in Zone 1, Zone 21 and 22 areas.
