A variety of workplaces may contain substances that can produce potentially explosive atmospheres. These substances can take the form of a flammable gas, vapour or combustible dust. Some examples of work activities or facilities which could contain or create a potentially explosive atmosphere are as follows:
Paint spraying (Liquid or Powder Coating)
Paint Spraying or Powder coating can form a Potentially Explosive Atmosphere, this is normally through the flammable mist which is generated during spraying of liquid paints or from a combustible dust cloud from the spraying powder coating paints.
The use of potentially combustible powders flammable liquids and gases in production of pharmaceuticals and the processes involved can lead to an explosive atmosphere being formed. This is normally from grinding/milling of powders for pill and medicine production.
Food production/flour mills
Certain types of food and dry produce used in the production of food or alcohol production such as flour, dried milk, instant coffee, soup powder and sugar can produce explosive dust clouds or form combustible dust layers. If a solid substance is finely ground it has the potential to ignite more readily.
Combustible wood dust is the very fine, dry wood particles that can occur as a by-product of mainly sanding wood. Commonly found in sawmills and wood workshops around sanding equipment and within the LEV Extraction systems, where there is an increased risk of fires and explosions if the correct precautions aren’t adhered to.
