Profile: Stonehouse Process Safety specializes in providing safety engineering services. We test and measure flammability, combustibility, explosibility, ignition sensitivity, explosion severity, thermal decomposition/self-heating, and electrostatic properties Our services include dust explosion testing, electrostatic testing, and flammability testing of gases & vapors. Self-heating of powders due to exothermic reaction (exothermic decomposition or exothermic oxidation) can result in smoldering, fire, and production of hot or incandescent particles which can travel along conveying equipment and act as an ignition source to dust clouds in downstream process equipment. Sometimes exothermic decomposition causes (rapid) evolution of large quantities of toxic or flammable gases.
