Lower and Upper Dust Explosion Limits


The Dust Explosion Limits describe the concentration range of types of dusts with air, within an explosion is possible.


Testing Method:

according to BG Chemie R 003 6/2000


Safety-relevant meaning:


For more detailed Information see also Explosibility of solids and dusts.


Based on the lower dust explosion Limit an explosion prevention concept can be compiled. In the view of safety relevance the upper dust explosion limit is of small importance in connection with dispersed dusts. Because of this a safety concept can´t be developed. Therefore it is usually not determined.
