Ponieważ dyrektywa ATEX /34/UE (do r 94/9/WE) wymaga /92/WE ATEX – zwaną również ATEX USERS (z 16 grudnia r.). Dyrektywa /92/WE Parlamentu Europejskiego I Rady z dnia 16 grudnia r. w sprawie minimalnych wymagań dotyczących bezpieczeństwa i ochrony . Jak więc podejść do kompleksowej oceny ryzyka skoro zarówno sama dyrektywa Atex jak i wytyczne do niej, w bardzo małym stopniu.

The regulations apply to all equipment intended for use in explosive atmospheres, whether electrical or mechanicalincluding protective systems.
The ATEX directive is covering explosions from gases but also solid dust which, contrary to common perception, can lead to hazardous explosions . In very broad terms, there are three preconditions for the directive to apply: See Wikipedia’s guide to writing better articles for suggestions. Industrial or Mining Application; 2. Retrieved from ” https: Zone 20 — A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is present continuously, or for long periods or frequently.
In DSEAR, an explosive atmosphere is defined as a mixture of dangerous substances with air, under atmospheric conditions, in the form of gases, vapours, mist or dust in which, after ignition has occurred, combustion spreads to the entire unburned mixture.
Methane, hydrogen or coal dust are examples of possible fuels. April Learn how and when to remove this template message. This article may be confusing or unclear to readers. Zone 0 — 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 present continuously or for long periods or frequently.
Zone 2 — 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 not likely to occur in normal operation but, if it does occur, will persist for a short period only.
The ATEX directive consists of two EU directives describing what equipment and work space is allowed in an environment with an explosive atmosphere. 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. From Wikipedia, the free encyclopedia. This standard given by the Occupational Safety and Health Administration defines and classifies hazardous locations such as explosive atmospheres.
Zone 21 — A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur in normal operation occasionally.

Manufacturers who apply its provisions and affix the CE marking and the Ex marking are able to sell their equipment anywhere within the European union without any further requirements with respect to the risks covered being applied. There are two categories of equipment ‘I’ for mining and ‘II’ for surface industries.
These latter devices may be outside the potentially explosive environment. The directive covers a large range of equipment, potentially including equipment used on fixed offshore platforms, in petrochemical plants, mines, flour mills and other areas where a potentially explosive atmosphere may be present.
