How accurately can we predict the LOC of a dust cloud?

In situations where dust explosion risks are prevented by working at low oxygen atmospheres as the basis of safety, the limiting oxygen for combustion (LOC) value for the dust is the key parameter to establish a safe oxygen level. The LOC can be determined experimentally, but can also, allegedly, be estimated based on other dust explosion properties. The purpose of this study is to determine whether the calculation method of determining a material’s Limiting Oxygen Concentration (LOC), as per the method proposed by R Siwek, 1996 is reliable enough to be used in explosion safety assessments, instead of determining the LOC by experimental method.
