Please help us clarify the article. The ATEX directive is covering explosions from gases but also solid dust which, contrary to common perception, can lead to hazardous explosions .

Accumulation of dust in workrooms is the cause of major explosions and its elimination is vital.
In small factories portable vacuum cleaners may be used provided the electrical equipment is safe for use when exposed to flammable dusts. Certification ensures that the equipment or protective system is fit for its intended purpose and that adequate information is supplied with it to ensure that it can be used safely.
For example, screw conveyors do not promote the formation of dust clouds internally and this fact may be reflected in a reduction of the zone designation from zone 20 to zone A static vacuum pump fitted to a ring main is more suitable for large factories; the ring main should be provided at intervals with facilities for the connection of flexible cleaning hoses.
