Tunnel boring machines - Air locks - Part 2: Safety requirements for the use of non-air breathing mixtures and saturation techniques in personnel locks and for pressurised transfer shuttles; German and English version prEN 12110-2:2023
Abstract
This document sets out additional requirements to those in prEN 12110-1 for personnel locks which are intended to have the capability for mixed gas breathing techniques or saturation techniques at pressures not exceeding 20 bar(g) and associated with tunnelling work. This document also sets out requirements for pressurized transfer shuttles.prEN 12110-1 applies to the design, construction, equipping, marking and testing of air locks in tunnelling. prEN 12110-1 also covers requirements for manlocks utilizing compressed air as the pressurizing and breathing medium along with requirements for oxygen breathing systems for decompression purposes. Air locks are normally an integral part of TBMs. Hence there are interfaces between the scope of prEN 12110-1:2023 and prEN 16191:2023. These are detailed in Clause 4 of this document.
