While there is extensive testing and validation of hazards from flammable vapors, less information is available regarding flammable liquid mists. A method is suggested for reasonably estimating the nature and severity of flammable liquid mist hazards by applying published mist property correlations to model inputs and outputs in dispersion modeling software. Better estimating these hazards is important to properly evaluate what mitigations will be needed. One common high fla

Have you ever had the problem of having a perfectly functional BPCS * interlock that you know is highly failure immune, yet when it comes time for the Hazard Analysis, you may only take one credit? Unfortunately, for facilities following the IEC 61511 safety lifecycle, any interlock not designed according to the standard is limited to one risk reduction credit. This can make meeting extremely low total mitigated event likelihood targets (such as 1x10-5 or 1x10-6) exceedingl
