It is nevertheless a common understanding of the ATEX Committee that after the date of application of the previous ATEX Directive 94/9/EC (1 July 2003), both electrical and non-electrical equipment used in machinery having a potentially explosive atmosphere inside must comply with the ATEX Directive, now 2014/34/EU (from 20 April 2016).
ATEX zones for dusts Dust clouds in the explosive region (above the minimum explosible concentration) are categorised into 3 zones, based upon the grade of release (as per EN6:2009): Zone 20 Continuous release inside a dust containment enclosure gives rise to Zone 20 - a place in which an explosive atmosphere, in the form of a cloud of combustible dust in …

The ATEX Directive 99/92/EC (also known as 'ATEX 137' or the 'ATEX Workplace Directive') In Europe, ATEX directive 99/92/EC sets out the minimum requirements for improving the health and safety protection of workers potentially at risk from explosive atmospheres.
Due to the nature of the environment Mining and Surface industries are treated differently, within the Atex Coding, equipment is classified in groups relating to the explosive atmosphere for which it is to be used; Group I for mining and Group II for surface use with an additional Group III for surface Dust.
What is an explosive atmosphere (hazardous area)? ... Dust: wood, sugar, grain, starch, coal... 3 - Presence of an ignition source, which is a source of energy strong enough to ignite the combustible: this can be in the form of a flame, a spark, or a high temperature. ...

Why an ATEX Conical Mill is Needed "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." 1 Hence, the presence of gas or dust in certain atmospheres can …
ATEX is a directive consisting of two European directives describing electrical or mechanical equipment allowed in an environment with an explosive atmosphere. ATEX derives its name from ATmospheres EXplosible and applies to all equipment intended for use in …
Regarding ATEX 99/92/EC Directive, the requirement is that Employers must classify areas where potentially explosive atmospheres may occur, into zones. 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.
A 'hazardous zone' is classified according to the likelihood and frequency that a potentially explosive atmosphere will exist with the risk of ignition. NOTE: A Safety Data Sheet (SDS) should list an individual material's explosive potential but it is the responsibility of the plant owner to assess the risk that an explosion will occur.
Zone 2 Gas. Zone 2 – according to ATEX a hazardous area location in which an explosive atmosphere consisting of a mixture with air of dangerous and flammable substances usually in the form of gases, mists or vapours is likely to occur in normal operation, but if it does occur, will persist for a short period only.
The ATEX directives consists of two EU directives describing the minimum safety requirements of the workplace and equipment used in explosive atmosphere. ATEX derives its name from "Appareils destinés à être utilisés en ATmosphères EXplosives" (French for Equipment intended for use in EXplosive ATmospheres).. Directives. Organisations in the EU must follow …
A potentially explosive atmosphere exists when a mixture of air gases, vapours, mists, or dusts combine in a way that can ignite under certain operating conditions. Equipment and protective systems intended for use in potentially explosive atmospheres (ATEX) cover a range of products, including those used on fixed offshore platforms ...
1. These ATEX Guidelines are intended to be a manual for all parties directly or indirectly affected by Directive 2014/34/EU1, commonly referred to as the ATEX ("Atmosphères explosibles") "product" directive, applicable from 20 April 2016, replacing the previous Directive 94/9/EC applicable from 1 July 2003 until 19 April 2016. 2. Readers' attention is drawn to the fact that …
The legal basis for production in explosion hazard conditions is determined by the EU ATEX 137 Directive (EN 99/92/EC). It was implemented in the Polish law by virtue of the Regulation of the Minister of Economy of 8 July 2010 regarding minimum requirements for occupational safety and health, related to potentially explosive atmosphere in the place of work (Journal of Laws of …
explosion limits are not limited just to a certain particle size of combustible dusts. Explosion limits (LEL, lower explosion limit) can only be detected by performing . specific tests. Extracted dust may create dust explosions. A precondition for a dust explosion is an . explosive environment. Dust explosions only occur under certain . conditions.
The coal mining, chemical and petrochemical sectors are of particular concern, but the food industry, mill operation, wastewater and biogas production sectors are also affected. These combustible substances can form a potentially explosive atmosphere when mixed with oxygen.
explosive atmospheres in the form of gases, vapors, mists or dusts are a present concern. The coal mining, chemical and petrochemical sectors are of particular concern, but the food industry, mill operation, wastewater and biogas production sectors are also affected. These combustible substances can form a potentially explosive atmosphere
In Europe, similar regulations have been enforced since the 90s and take the name ATEX (Atmosphere Explosive). A dust explosion analysis is also required. ... On the other hand, for a mill reaching 20-40 m/s in tip speed, the risk will be high that sparks happen in case of malfunction or presence of foreign bodies. 3. Step 3 Calculate the risk

ATEX stands for AT mosphère EX plosibles (from the French for Explosive Atmospheres). Formerly it combined two European Union (E.U.) Directives for defining environments where an atmospheric explosion hazard existed. There were a confusingly large number of variants describing the two main directives for ATEX.
European Union - ATEX. Any manufacturer producing electrical equipment intended for use in potentially explosive atmospheres in the EU must comply with ATEX Directive 2014/34/EU. Such products must bear the ATEX mark (an "Ex" in a hexagon) as well as CE marking before being sold in the EU. This is achieved by evaluating and testing to EN ...

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.
ATEX Directive1999/92/EC deals with the precautions to be taken in workplaces where explosive atmospheres might be present due to flammable dusts vapours or gases (or mixtures of these). This directive is transposed into Irish legislation by Part 8 of the 2007 Safety Health & Welfare at Work (General Application) Regulations. Back to top.
