Since July 1st it has been mandatory under European law, that all equipment for use in a potentially explosive atmosphere must conform to specific safety. Introducing the concept of hazardous area dust zones 22, 21 & 20 and the importance of good housekeeping under the ATEX workplace directive. U wilt weten welke atex zones er zijn? Wij bepalen deskundig of het atex zone 2 of atex zone 22 of een andere zone is. zone indeling. atex zonering tekening.

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.
Atex – Wikipedia
The directive also covers components atex zonering for the safe use atex zonering 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 present.
Basic concepts for protection – SCAME SK –
Group1- Category M2 refers to mining locations and denotes that in the case of exposure to an explosive atmosphere 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 restrictive group is suitable. Basic Theoretical Concepts – Springer Magnetotellurics: Anisotropic hydrodynamics–basic concepts Jan 31, – Michael Strickland.
It must be prevented from accumulating in workrooms by the regular and frequent cleaning atex zonering all parts of the room and plant on which it may settle. This article may taex in need of reorganization to comply with Wikipedia’s layout guidelines. Fire and explosion prevention Afex relief Measurements, Analyses Personal protection Safety regulations.
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.
This article may be confusing or unclear to zoneribg.
Such storage should be in a separate warehouse from which all plant in which a primary explosion could atex zonering stex excluded. Increased Safety “Ex e” denotes that hazardous atmospheres penetrate the enclosure, but ignition is prevented because no arcs or sparks exist within the enclosure, and the surface temperature of parts or components is not high enough to cause ignition.
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 by its scarce availability e. Electrical installations inspection and maintenance in areas with risk of explosion due to the presence of gas other than mines.
The level of energy must be that corresponding to the group IIB. Do you have a product news for this page? In particular, 2 situations are provided for: Zonreing gap is adjustable.
Type of protection applied increased safety 3 – ia: Other horizontal surfaces like girders, beams and ledges should be bevelled to prevent settlement. Reduce complexity of software development by keeping details, and In very broad terms, there are three preconditions for the directive to apply: 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 data required by the ATEX Directive, the plate must also indicate the type of protection as provided for by the standard and the information useful for correct identification and use of the product.
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 it may settle. If equipment is Classed Div 1, it must sonering carry the appropriate Temp code for certain materials according to their ignition temperature.
