All results are clearly summarized in the reporting format and provide the foundation for drawing the zones in the zoning plan. The regulations apply to all equipment intended for use in explosive atmospheres, whether electrical or mechanicalincluding protective systems.
Explosion properties of all used substances Then the explosion properties of the substances used are listed, such as the Kst, the flash point, the minimum ignition energy or the maximum permissible surface temperature. 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.
Zone 21 Primary grade of release gives rise to 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. A static vacuum pump fitted to a ring main is more suitable for large factories; the ring main should be provided at intervals with facilities for the connection of flexible cleaning hoses.

Zone 1 — A place in which an explosive atmosphere consisting of a mixture with air of dangerous substances in the form of gas, vapour or mist is likely to occur in normal operation occasionally.
The following precautions should be observed: No arcs, sparks, or hot surfaces. The use of compressed air for cleaning is not recommended. Once flammability is established, zoning is determined following the grade of release: Which lead to the following: This article has multiple issues.
Atmospheric conditions are commonly referred to as ambient temperatures and pressures. Please help by editing the article to make improvements to the overall structure.
