Harmonised requirements for the Manufacturer to sell to the User: the ATEX 95 equipment directive 94/9/EC, Equipment and protective systems intended for use in potentially explosive atmospheres, these are supported by EN standards. Employers must classify areas where hazardous explosive atmospheres may occur into zones.
explosive atmospheres. ATEX 95 (also referred to as ATEX 100) covers the responsibilities of manufacturers to supply equipment offering varying degrees of protection to suit a particular level of hazard. ATEX 137 (also referred to as ATEX 118) covers the responsibilities of end users to prevent accidents due to hazardous atmosphere occurring on ...

explosion protection, and is the basis for the operation and connection of several electrical devices in the hazardous zones 0 and 1. According to the ATEX directive, an EC‐type examination certificate is not mandatory for devices of category 3 as specified for use in Zone 2, and
Mining of coal leads to coal dust, and flour mills likewise have large amounts of flour dust as a result of milling. A gigantic explosion of flour dust destroyed a mill in Minnesota on May 2, 1878, killing 14 workers at the Washburn A Mill and another four in adjacent buildings.
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 2040 m/s in tip speed, the risk will be high that sparks happen in case of malfunction or presence of foreign bodies. 4. Calculate the risk
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.
1 The explosion is believed to have been fueled by the everpresent sugar dust, an inherent aspect of the sugar refining process, which would coat surfaces and equipment in the facility.. A resulting investigation performed by the Chemical Safety Board looking into the explosion concluded that the incident was "entirely preventable" and was the result of "inadequate equipment design, poor ...

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 ...
Fit silos or bins with explosion relief and vent to an unoccupied place of safety, preferably outside the building. Ensure that the venting system is designed to an acceptable standard. Vent openings should be unrestricted to allow the free venting of an explosion. Protective systems such as explosion relief panels need to be ATEX certified.
As part of Patlite''s motto for "Safety, Security and Comfort", we include the motto in the explosive environment with our Explosionproof product line. Our company utilizes certified agencies to ensure that our Explosionproof products follow the strict demands required to meet the specific standards, such as ATEX and IECEx.
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 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 .
Zone 21 (ATEX 1999/92/EC) definition. What is a Zone 21 hazardous area? A Zone 21 area is classified as a place in which an explosive atmosphere consisting of a mixture with air or flammable substances in the form of powder or dust is likely to occur in normal operation occasionally.
Explosion Protection For Coal in the Cement Industry White Paper Explosion Prevention White Paper Declan Barry Warrington Lane Lymm, Cheshire WA13 0SW, UK P a g e | 1 The Cement Industry Problem An explosion is a deflagration or fire ball in a confined atmosphere, with parts of the confinement disintegrating and been blown apart.
An explosive atmosphere is a mixture of a dangerous substance or substances (gas, mist, dust or vapour) mixed with air (oxygen), which has the potential to catch fire or explode. There are obvious workplaces where you would expect explosive atmospheres to be found (and controlled) such as: coal mines, oil rigs, gas rigs, and refineries.
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
Since July 1st 2003 it has been mandatory under European law, that all equipment for use in a potentially explosive atmosphere must conform to specific safety standards. Many manufacturing processes, including biodiesel production, generate potentially explosive atmospheres. Biodiesel chemistry : Biodiesel standards : Biodiesel uk excise
Legal directives such as NEC/CEC in the USA and Canada, and Europe''s 2014/34/EU (ATEX) are in place alongside other regulations to reduce the risk of explosions in high risk operating areas and increase industrial machine safety. For an ATEX certificate approval the areas will be divided by explosion hazard risk zones.
The ATEX directive consists of two EU directives describing what equipment and work space 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 EXplosives
What is an explosive atmosphere? An explosive atmosphere is an accumulation of gas, mist, dust or vapour, mixed with air, which has the potential to catch fire or explode. An explosive atmosphere does not always result in an explosion, but if it caught fire, the flames would quickly travel through it.
