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
There are many devices (sensors, logic solvers and final elements) used in safety instrumented systems that are independently certified for use in safety applications to different safety integrity levels (SIL). There is considerable debate however whether fire and gas system hardware should have SIL ratings at all. Vendors are naturally interested in promoting independently certified hardware in order to differentiate their products. Considering the differences between safet
