Imperial Sugar Dust Explosion, 2008 The dust of many materials in everyday use such as coal, wood, cork, grain, starch, sugar, certain metals, some dyes and intermediates, and many plastics, can form explosive dust clouds. Explosions of such clouds have caused some of the worst industrial accidents.

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 ch 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.
ATEX Conical Mill for Use in Explosive Atmospheres
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
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
ATEX Standard ATEX Directive 94/9/EC European Law ATEX Directive 94/9/EC ATEX is named after the French "ATmosphère EXplosible" 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
WHAT IS THE DIFFERENCE BETWEEN ATEX & IECEx CERTIFICATION
There are a number of places that could be defined as being in an explosive atmosphere, some more obvious such as an oil rig, and others that you might not think of as being particularly explosive, such as a flour mill. Most of us have heard of ATEX and IECEx certifiion, but the question that a lot of people ask is what makes them different?
ATEX/IECEx Markings Explained Area Classifiion Equipment Category Definition Zone An area where an explosive atmosphere is present continuously or for long periods (over 1000 hours per year or >10% of the time) An area where an explosive atmosphere is likely to occur in normal operation (10 1000 hours per year or 0.1 to 10% of the time)
1. Introduction : What is ATEX zoning ? The european ATEX directives 94/9/CE and 1999/92/CE, revised in 2014, have introduced the notion of zoning in order to identify and classify areas within a factory that present a risk of presence of powder cloud in explosive conditions.

ATEX 137 Leading digital technologies for industry
ATEX divides plants up into zones according to the level of risk. Where explosive atmospheres occur briefly and infrequently, the area is Zone 2 for gases, vapours and mists or Zone 22 for dusts. Zones 1 and 21 cover areas where explosive atmospheres are likely to

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 saftey requirements and conformity assessment procedures, to
Chain conveyors can be used to transport any type of bulk material safely, gently, with allround protection and with minimum space requirements. They can transport coal, sorted domestic waste, sewage sludge, filter dust, fly ash, wood chips, cement, clinker, limestone, biomass or alternative fuel.
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.
