  • Basics of Explosion Protection INTRODUCTION

    EQUIPMENT DESIGN AND CONSTRUCTION There are a number of methods of protecting electrical equipment, which prevent an explosion when used in a flammable gas atmosphere, in the presence of combustible dust or easily ignited fibers. Three elements are required for an explosion to occur fuel, oxygen and a heat or ignition source must be present.

  • Dust explosion Wikipedia

    A dust explosion is the rapid combustion of fine particles suspended in the air within an enclosed location. Dust explosions can occur where any dispersed powdered combustible material is present in high-enough concentrations in the atmosphere or other oxidizing gaseous medium, such as pure oxygen.

  • ATEX dust zones Zone 20 Zone 21 Zone 22

    This shock is often caused by a relatively mild primary explosion inside the plant, the flame from which serves as a means of ignition for the dust cloud formed in the workroom. This secondary explosion disperses more of the dust accumulated in the workroom and ignites these clouds until the whole building is swept by the explosions.
