atex atmosphere explosive coal milling in pakistan

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 EN600791022009 Zone 20

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 their premises

ATEX and explosive atmospheres Explosive atmospheres in the workplace can be caused by flammable gases mists or vapours or by combustible dusts Explosions can cause loss of life and serious injuries as well as significant damage These pages will tell you more

Sources of dust Explosive dust can arise from activities such as transporting grain and grain silos have often been demolished violently 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

fl ammable substances that are not capable of forming an explosive atmosphere However it is not always possible to exclude fl ammable substances such as methane or coal dust in mines or petrol and in future perhaps hydrogen in vehicles In such cases protection and safety are provided by equipment which is reliably explosion proof

ATEX directive Wikipedia The ATEX directive consists of two EU directives describing what equipment and work The classification given to a particular zone and its size and location mines flour mills and other areas where a potentially explosive atmosphere may be present Methane hydrogen or coal dust are examples of possible fuels
