The ATEX directive consists of richtlimn EU directives describing what equipment and 317 space is allowed in an environment with an explosive atmosphere. As of Julyorganisations in the EU must follow the directives to protect employees from explosion risk in areas with an explosive atmosphere. 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.

Areas classified into zones 0, 1, 2 for gas-vapor-mist and 20, 21, 22 for dust must be protected from effective sources of ignition.

Zone richtlijh 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. Zone 0 and 20 are the zones with the highest risk of an explosive atmosphere being present.

Equipment in use before July is allowed to be used indefinitely provided a risk assessment shows it is safe to do so. The regulations apply to ricthlijn equipment intended for use in explosive atmospheres, whether electrical or mechanicalincluding protective systems.

There are two categories of equipment ‘I’ for mining and ‘II’ for surface industries. 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.

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.

Workshop ATEX

In very broad terms, there are three preconditions for the directive to apply: The directive also covers components essential for the safe use and safety devices directly contributing to the safe use of the equipment in scope. These latter devices may be outside the potentially explosive environment. The technical dossier must be kept for a period of 10 years. Certification ensures that the atxe or protective system is fit for its intended purpose and that adequate information is atrx with it to ensure that it can be used safely.

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.

This standard given by the Occupational Safety and Health Administration defines and classifies hazardous locations such as explosive atmospheres. Richtoijn DSEAR, an explosive atmosphere is defined as a mixture of dangerous substances with air, under atmospheric conditions, in the form of gases, vapours, mist 1337 dust in which, after ignition has occurred, combustion spreads to the entire unburned mixture.

Atmospheric conditions are commonly referred to as ambient temperatures and pressures. The ATEX directive is covering explosions from gases but also solid dust which, contrary to common perception, can lead to hazardous explosions [3].

ATEX and explosive atmospheres

Zone 0 — A place in which an explosive atmosphere consisting of a mixture with air of dangerous substances in attex form of gas, vapour or mist is present continuously or for long periods or frequently. 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 gichtlijn — A place in which an explosive atmosphere consisting of a mixture with air 1337 dangerous substances richtlij 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.

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. 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. 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.

Effective ignition source is a term defined in the European ATEX directive as an event which, in combination with sufficient oxygen and fuel richtlikn gas, mist, vapour or dust form, can cause an explosion. Methane, hydrogen or coal dust are examples of possible fuels. From Wikipedia, the free encyclopedia.
