Typical ATEX Marking


Who do these regulations apply to?
The Regulations apply at most workplaces where flammable substances are stored or used, for example, factories where flammable liquids are present or where flammable dusts are produced in the process.

Examples are chemical processing, spraying of paint and varnishes, LPG storage and filling, milk drying, flour production


What is a flammable substance?
Flammable substance includes any substance or preparation, which because of its properties or the way it is used can cause harm to people from fires and explosions.

Examples of flammable substance are: petrol; liquefied petroleum gas (LPG); paints; varnishes; solvents; and dust which when mixed with air could cause an explosive atmosphere, for example, dust from milling and sanding operations.  Flammable substances can be found, in varying quantities, in most workplaces.


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 catch 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.  If this happens in a confined space (e.g. in plant or equipment) the rapid speed of the flames or rise in pressure could also cause an explosion.
