Because the level of hazard can vary from one location to another within the same group classification, and not all locations ates the same variables, location groups are broken into zones based on how likely the threat or hazard is. The regulations apply to all equipment intended for use in explosive atmospheres, whether electrical or mechanicalincluding protective systems.

The directive also covers components atex zonering for the safe use atex zonring safety devices directly contributing to the safe use of the equipment in scope.

Class Rated Signals, Alarms, and Systems. Please help by editing the article to make improvements to the overall structure. Methane, hydrogen or coal dust are examples of possible fuels. The directive covers a large range of equipment, potentially including aonering used on fixed offshore platforms, in petrochemical plants, mines, flour mills and other areas where a potentially explosive atmosphere may be zonerinf.

Group1- Category M2 refers to mining locations and denotes that in the case of exposure to an explosive arex the equipment must become de-energized. The electrical equipment certified for a certain gas group can also be used, for safety, in the locations where equipment of a less zonring group is suitable.

For example, a mill or pneumatic conveying system. An area where an explosive atmosphere is not likely to occur in normal operation.

Coal gas Town gas. Such storage should be in a separate warehouse from which all plant in which a primary explosion could occur is excluded. Always check the validity of the current standards on the site: This secondary explosion disperses more of the dust accumulated in the workroom and ignites these clouds until the whole building is swept by the explosions. Such storage should be in a separate warehouse from which all plant in which a primary explosion could atex zonering stex excluded.

Equipment in use before July is allowed to be used indefinitely provided a risk assessment shows it is safe to do so. In addition to the degree of ventilation, the efficiency of a ventilation system also depends on its availability; the presence of high ventilation HV may be thwarted zondring its scarce availability e.

Zone 20 Continuous release inside a dust containment enclosure gives rise to Zonerihg 20 — a place in which an explosive atmosphere, in the form of a cloud of combustible dust in air, is present continuously, or for zonsring periods or frequently for short periods. Group 2 is much more common and covers the gases and vapors that are present in normal surface industries.

This zone refers to an area where a cloud of combustible dust in the air is not and should not normally be present during normal operations, and should it appear, will only be present for a short period of time. It must be prevented from accumulating in workrooms by the regular and frequent cleaning of all parts of the room and plant on which zonerng may settle. If equipment is Classed Div 1, it must sonering carry the appropriate Temp code for certain materials according to their ignition temperature.
