Andrew R. Carpenter, P.E.

Mr. Carpenter applies his expertise in chemical engineering to the scientific investigation of fires and explosions, reactive chemical accidents, chemical releases, chemical process and production analysis, process safety and risk assessment, and complex chemical process accident investigation. Mr. Carpenter has investigated and reconstructed numerous accident investigations relying upon a wide variety of information sources including on-scene investigations, artifact examinations, process and instrumentation data, witness interviews, and laboratory testing.

His accident investigations have included residential, commercial, and industrial fires and explosions; thermal decomposition of reactive chemicals; pressure relief systems; pressure vessels; railcars; air pollution equipment; and a wide variety of consumer products and chemicals. Mr. Carpenter has designed experimental test programs to evaluate various engineering issues associated with these investigations including full-scale fire testing, chemical compatibility, and thermal stability.

Mr. Carpenter’s chemical facility process investigations have included the study of facility start-up operations, historical performance, evaluation of maximum production capacity, and the assessment of system safety. He has performed these studies for a wide variety of chemical processes and industries including oil and gas, plastics, specialty chemicals, and medical sterilization. In addition, Mr. Carpenter is a qualified process hazard analysis (PHA) facilitator and has led numerous HAZOP, What-If, and LOPA studies.

Mr. Carpenter’s research interests include process safety, flammable liquid and vapor fuel storage, self-heating and thermal decomposition of reactive chemicals, safety instrumented systems, and alternative vehicle fuels. Mr. Carpenter is a licensed Professional Engineer in the states of Illinois and Ohio.
