Combustible Dust Hazard Analysis (DHA) testing options in the 20L chamber - The collected sample has gone through the screening process and now moves in the 20L chamber queue for testing. We explain the different options available for testing starting with a confirmation of the Go/No Go result in the Modified Hartmann Tube. We also cover the Explosion Severity Test, which finds the KSt and Pmax values and what those results are telling you about your material. We also move into the Minimum Explosible Concentration or MEC and the Limiting Oxygen Concentration or LOC and what the test results are doing in helping your operation stay safe.
