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.

Zone 0 and 20 require Category 1 marked equipment, zone 1 and 21 require Category 2 marked equipment and zone 2 and 22 require Category 3 marked equipment. There are two categories of equipment ‘I’ for mining and ‘II’ for surface industries. Please help by editing the article to make improvements to the overall structure. The ATEX directive consists of two EU directives describing what equipment and work space is allowed in an environment with an explosive atmosphere.
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. There might be a discussion about this on the talk page. 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.
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.

Effective ignition source is a term defined in the European ATEX directive as an event which, in combination with sufficient oxygen and fuel in gas, mist, vapour or dust form, can cause an explosion.
The classification given to a particular zone, and its size and location, depends on the likelihood of an explosive atmosphere occurring and its persistence if it does.
Zone 22 — A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to occur in normal operation but, if it does occur, will persist for a short period only.
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. The technical dossier must be kept for a period of 10 years.

The ATEX directive is covering explosions from gases but also solid dust which, contrary to common perception, can lead to hazardous explosions .
Please help us clarify the article. This article has multiple issues.
This standard given by the Occupational Safety and Health Administration defines dyrektywwa classifies hazardous locations such as explosive atmospheres. From Wikipedia, the free encyclopedia. There are four ATEX classification to ensure that a specific piece of equipment or protective system is appropriate and can be safely used in a particular application: Industrial or Mining Application; 2.

Atmospheric conditions are commonly referred to as ambient temperatures and pressures. Zone 0 and 20 are the zones with the highest risk of an explosive atmosphere being present.
See Wikipedia’s guide to writing better articles for suggestions.
This page was last edited on 5 Novemberat 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.
April Learn how and when to remove this template message. 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. Certification ensures that the equipment or protective system is fit for its intended purpose and that adequate information is supplied with it to ensure that it can be used safely. As of Julyorganisations in the EU must follow the directives to protect employees from explosion risk in areas with an explosive atmosphere.
Equipment in use before July is allowed to be used indefinitely provided a risk assessment shows it is safe to do so. Views Read Edit View history. Electrical engineering European Union directives Explosion protection Electrical safety Certification marks Natural gas safety Standards.

The regulations apply to all equipment intended for use in explosive atmospheres, whether electrical or mechanicalincluding protective systems. Methane, hydrogen or coal dust are examples of possible fuels. Retrieved from ” https: Areas classified into zones 0, 1, 2 for gas-vapor-mist and 20, 21, 22 for dust must be protected from effective sources atx ignition.
