The implementation of the new technical rule TRBS 2153 (BGR132) gives rise to numerous questions and uncertainties in day-to-day practice. In an attempt to provide reliable answers and clarify the situation with regard to suction and transport hoses, NORRES, the Gelsenkirchen based hose manufacturer, hosts a meeting of experts at the end of November. The eminent panel includes Dr. Josef Bremen of BG Chemie in Cologne, one of the fathers of both the new and the old rule, and Dr. Claus-Diether Walther of Currenta, Leverkusen, a recognised authority on explosion protection.
