Measuring Dust Combustibility

Dust combustibility is determined by measuring the explosive index (Kst) and the maximum pressure rise (Pmax) of your dust. The Kst and Pmax values of your dust will indicate what dust collection, explosion ventilation, and fire suppression system your company will need.

Any Kst value above zero must be addressed.

Typical Kst Values of Dusts Commonly Found in Industrial Facilities

Common Dusts Kst Value
Activated Carbon 44
Aluminum Powder 400
Asphalt 117
Charcoal 117
Cotton 24
Milk Powder 90
Paper Tissue Dust 52
Rice Starch 190
Soap 111
Soy Bean Flour 110
Toner 145
Wood Dust 102

Did you know … OSHA, NFPA, and your insurance company require third party testing results on dust combustibility.
