Dust explosions are a serious hazard in process industries. Explosion events can cause loss of land, labor, capital and in the very worst cases, life. At least 281 combustible dust fires and explosions occurred in general industry between 1980 and 2005. limit (LEL), Kst value the company is required to take steps according to ATEX 137. Critical safety measures: • Zone division depending on the explosion risk • Labelling hazardous areas • Determine which protective actions to implement • Operation instructions for employees • Creating an explosion prevention INTRODUKTION • EUs och EES krav inom ATEX-området • Hur är regelverket uppbyggt?

Dust explosion classifications Kst = It is a dust deflagration index, an explosion constant that measures the speed of pressure increase during a dust explosion. It is measured in bar m/sec. and also gives an indication of the spread of the flames.Kst represents a fundamental parameter for sizing the safety panel (see details below); The Kst value is calculated as the equivalent pressure in a 1 m 3 sphere from the cube law (Kst value = cube root of volume x explosion pressure rise). TEST The explosion severity test is conducted to determine maximum pressure (Pmax), Maximum rate of pressure rise ((dP/dt)max) and Kst of an ignited powder, dispersed in air, as a dust cloud.

To separate different dust types based on their Kst value into categorical protection groups, we use classes ST1, ST2 and ST3. There is a risk of explosion in all extraction systems in which flammable dusts occur. Under certain conditions an explosive mixture forms in these "Ex-areas" in connection with air. A small spark (e. g. due to static charge) is sufficient to cause a dust explosion.. To ensure that our extraction systems can be configured for explosion protection and ATEX extraction, certain parameters must be Kst value greater than 300 bar m/sec.

For St3 rated materials, the actual explosibility – kSt should be known in order to determine the nature and capacity of necessary protective devices for ATEX compliance.

When a fine dust suspended in the atmosphere is ignited, it causes a very rapid burning followed by release of gaseous substances.

Material names are retrieved as phrase, e.g. searching for resin retrieves epoxy resin. search for :. The GESTIS-DUST-EX database presently contains combustion and explosion characteristics of 6805 materials. L'écluse ATEX représente un composant compartimentant de l'installation, car elle empêche l'explosion de se propager dans la zone d'évacuation de la poussière, protégeant ainsi l'intégrité de la machine et la sécurité des personnes se trouvant à proximité. All of our vents incorporate a vacuum hold of -200mbar (with the exception of the Easy Vent AL-E which resist to -50mbar) and a KST up to 500bar.m/sec. East Vent AD-E Explosion vent panels with Pstat of 100mbar @20°C (+/-15%), an efficiency rate of up to 100%, a vacuum resistance (max.) of 200mbar, KST (max.) of 500 bar*m/s, EPDM seal (-40 - +80°C), stainless steel panel (304L).
