    Abstract - (Show below) - (Hide below)

    Applies for the design, construction, equipping, marking and testing of air locks and pressure bulkheads, which are to be used in tunnelling work. Covers the oxygen breathing installation used to provide the breathing supply necessary to conduct a safe decompression. Deals with all significant hazards, hazardous situations and events relevant to air locks and pressure bulkheads, and specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards.
