Dust Explosion Protection
Treatment of Fire and Dust Explosions in ATEX
The inadequate treatment of the differences between clouds of combustible dust and explosive gas clouds has resulted in deficiencies in two ATEX directives, which, therefore, need to be revised.
In reality the two European Directives 94/9/EC (1994) and 1999/92/EC (1999) primarily address gases/vapours, whereas the particular properties of dusts are treated rather inadequately. Some recent IEC and European dust standards resulting from this deficiency are discussed, and the need for revising the two directives accordingly is emphasized.
