In chemical processes H 2 S in higher concentrations is used or arises during the process. The detailed knowledge of the lower respectively the upper explosion limit (LEL and UEL) is therefore necessary for a safety evaluation. The bomb method of the new European Norm EN 1839 represents the state of the art and serves for a revision of data from elder literature. The determined explosion limits of the two ternary gas systems H 2 S/CO 2 /air and H 2 S/N 2 /air show, for example, that for the UEL higher amounts of H 2 S were found than the reported ones. All new data will be recorded in the database “CHEMSAFE”.
