Handbook of Explosion Prevention and Protection

Dr. Martin Hattwig studied chemistry at the University of Goettingen. In 1966, he obtained his doctor's degree at the Institute of Physical Chemistry with a thesis on the one-stage cool flame of methyl-ethyl-ether. From 1966 on, he worked at the Federal Institute for Research and Testing Materials (BAM) as a scientific collaborator of Prof. Heinrich, and became head of the laboratory "Explosion dynamics" in 1969. His main fields of activity were the venting of explosions, detonations of gaseous systems, and safe handling of degreasing solvents. Since 1989 he also participated extensively in European standardization and legislation concerning explosion safety. From 1983 to 2001 he was head of the division "Heterogeneous Combustion Reactions" at BAM. Dr.-Ing. Henrikus Steen studied Thermodynamics and Chemical Engineering at the Technical University of Braunschweig. From 1965, he worked as scientific collaborator of Karl Nabert and Prof. Gerhard Schoen at the Physikalisch-Technische Bundesanstalt (PTB), Braunschweig. He occupied himself with all problems of safety techniques, especially with explosion prevention and protection when handling flammable liquids. 1973 he obtained his doctor's degree from the Technische Hochschule Aachen with a thesis on the vaporization in spray jets. Also in 1973, he became head of laboratory "Flammable Liquids" at the PTB. In 1980, he became head of the division "Fundamentals of Physical Safety techniques" at the PTB, and from 1989 to 1995, he headed the Department "Chemical Safety Techniques" at the Federal Institute of Materials Research and Testing (BAM), Berlin.
