The traditional ignition triangle shows the 3 parts which are required to be present 1 for an explosion to occur and in the protection methods detailed in the EN 60079 standards are designed to remove at least one of those parts, the exception being Ex d flameproof 2.. Fuel can be Dust or Gas/vapour, Although the purists would argue Gas and vapour are different, within the context of Hazardous ...
Jul 23, 2017· What does ATEX mean?: ATEX is a certification that determines the equipment that is allowed to be used within an explosive or hazardous environment. ATEX itself is an acronym: AT mosphere EX plosibles (French: Explosive Atmospheres) Certification ensures that the equipment (or protective system) is fit for its intended purpose.
Jun 25, 2017· ATEX ATEX consists of two European (EU) directives. They are: • The ATEX 95 equipment directive 94/9/EC, equipment and protective systems intended for use in potentially explosive atmospheres; • The ATEX 137 workplace directive 99/92/EC, minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres
ATEX is the name commonly given to the two European directives for controlling explosive atmospheres. ATEX lifting equipment can mean electric chain hoists, wire rope hoists and belt hoists, winches, trolleys and pneumatic lifting equipment, and can be referred to as spark proof or Ex equipment.
EU legislation and ATEX. The ATEX Directive 2014/34/EU covers equipment and protective systems intended for use in potentially explosive atmospheres. The directive defines the essential health and safety requirements and conformity assessment procedures, to .
ATEX Category Equipment Protection Levels Typical Zone Suitability 0 A place in which an explosive atmosphere is continually present 1 G Ga Equip. suitable for Zones 0,1,2 20 1 D Da Equip. suitable for Zones 20,21,22 1 A place in which an explosive atmosphere is likely to occur in normal operation occasionally 2 G Gb Equip. suitable for Zones 1,2
Technical Article: Understanding ATEX Milling Introduction to ATEX. Past legislation to control explosive atmospheres has only been concerned with electrical equipment. The current ATEX directives now include hazards from mechanical sources, such as mills. A seized bearing or mechanical failure causing excessive heat generation is as likely a ...
An explosive atmosphere does not always result in an explosion, but if it caught fire, the flames would quickly travel through it. If this happens in a confined space ( in plant or equipment) the rapid speed of the flames or rise in pressure could also cause an explosion.
Nonelectrical equipment is also subject to the requirements defined by the ATEX explosion protection directive. Rexroth has carried out and documented an ignition risk assessment DIN EN 134631 for these product series and thus meets the basic health and safety requirements defined by explosion protection directive 2014/34/EU.
Every company must classify in ATEX zones the areas where explosive atmospheres may form and where special precautions need to be taken to protect the safety and health of workers. Aspects to be considered: the type of substance causing the explosive atmosphere, the frequency with which it .
What is ATEX? The ATEX directive consists of two EU directives describing what equipment and work environment is allowed in an environment with an explosive atmosphere. ATEX derives its name from the French title of the 94/9/EC directive: Appareils destinés à être utilisés en ATmosphères EXplosibles. Hazardous Area Products with ATEX and IECEx Certification Deeter> view full article
Explosive or potentially explosive atmospheres may occur in many workplaces, where work activities create or release flammable gases, mists or vapours or combustible dusts. Working in such workplaces is hazardous because of the risk of fire and explosion that can cause loss of life, serious injuries, damage to property and the environment, and ...
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.
ATEX Conical Mill for Use in Explosive Atmospheres 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 ...
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 EN: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 air, is present continuously ...
Oct 05, 2018· Brown coal, steel dust or flour are examples for those substances which generate an explosive atmosphere within the plant and must consequently be treated with special care and attention. Gross negligence and disrespect of the ATEX Directive may entail heavy sanctions, if damages or even explosions occur in the plant.
ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres: 1) Directive 99/92/EC (also known as ''ATEX 137'' or the ''ATEX Workplace Directive'') on minimum requirements for improving the health and safety protection of workers potentially at risk from explosive atmospheres.
May 10, 2019· Therefore, the process must be controlled in order to limit these factors which can lead to an explosion; hence the need for an ATEX conical mill. A failure on milling equipment (or any other size reduction machinery) could result in excessive heat generation and has the potential to cause an explosion in a laboratory or manufacturing plant.
Ex and ATEXApproved Connectors Phoenix Contact offers a range of PCB terminal blocks and PCB connectors with IECEx approval for use in potentially explosive environments, including lighting and building automation applications. Solutions are available with 2–16 contacts on,, and pitches and screw, spring, or pushin ...
The ATEX Directive is a collection of EU directives outlining equipment installed and operated in potentially explosive atmospheres. The ATEX directive coordinates various technical and legal conditions throughout Europe to ensure a high level of safety for the enduser by reducing the explosion risk through established design methods.
tially explosive atmospheres may be formed (like a coal mill installation). In these cases, effective ignition sources must be eliminated or—if elimination is not possible—the process equipment must be designed and constructed to limit the effects of an explosion to a safe level. Here the Ignition hazard analysis is part of the
The ATEX (fr. ATmospheres EXplosives) European directive requires all heads of organisations to have a full understanding of any risks related to explosive environments. ATEX regulation requires a full explosive evaluation of the company to identify potential explosive environments, measures are then put in place to avoid explosions.
ATEX is a directive used worldwide for equipment, including encoders, to be used around or in explosive atmospheres. ATEX certified equipment is NOT necessarily interchangeable with USbased UL Class/Division or Class/Zone rated equipment, nor IECEx rated equipment. ATEX .
Having left the mill at the top, the final product continues with the gas to the filter or cyclone, where it is collected. Tailormade layout The layout of your coal grinding system must take into account the available heat sources for drying the raw coal as well as the fire and explosion hazards of coal and coal dust. The entire grinding
