Process, safety and operations engineers on sites handling powders, polymers, catalysts, monomers, peroxides or other reactive materials; PHA leaders
Combustible dust and reactive chemistry are the hazards most often absent from a hydrocarbon site's PHA, and both have produced fatal explosions in plants that thought they were low risk. The morning covers dust explosibility, the dust hazard analysis required by NFPA 652/660 and the prevention and protection measures of NFPA 68 and 69. The afternoon covers reactive-chemical screening, incompatibility, thermal runaway and the design and operating controls that keep a reaction inside its envelope.
Dust explosion mechanisms and case histories · explosibility parameters and testing · dust hazard analysis to NFPA 652/660 · deflagration venting, suppression and isolation (NFPA 68/69) · housekeeping, ignition sources and Ex equipment
Reactive-chemical case histories · reactivity screening and compatibility matrices · calorimetry: DSC, ARC and what the data mean · runaway reaction scenarios and emergency relief basis · operating controls, safe limits and PHA integration · reactivity screening on participants' chemicals
