The evaluation may include reaction calorimetry, adiabatic calorimetry, and temperature ramp screening using accelerating rate calorimetry, a reactive system screening tool, isoperibolic calorimetry, isothermal storage tests, and adiabatic storage tests. The results of the hazardous chemical evaluation are used to determine to what extent detailed thermal stability, runaway reaction, and gas evolution testing is needed. Mechanical sensitivity (mechanical impact and friction) 7. Solid (dust), liquid, and/or vapor flammability or ignitability properties 5.Ĭommon contaminant reactivity (e.g., rust, heat transfer fluid, scrubber solutions) 6. Petrochemical and chemical processes may contain additional processes that need to be evaluated as applicable on raw materials, catalysts, intermediates, products, byproducts, unintended products, solvents, inhibitors, quenchers, decomposition products, and cleaning products, such as: 1.
