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
oSIST prEN 12110-2:2023

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 as defined in 3.1.
prEN 12110-1 applies to the design, construction, equipping, marking and testing of air locks, as defined in 3.3, 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 16191:2022. These are detailed in Clause 4 of this document.
The intended use of the machinery is agreed between the manufacturer and the user taking into account information on intended use, exposure techniques and decompression procedures provided by the user.
This document is not applicable to machinery and equipment which is manufactured before the date of publication of this document by CEN.
NOTE   This document can help the design of air locks and bulkheads in other compressed air work in construction.
This document deals with all significant hazards, hazardous situations and events relevant to such machinery when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A).
This document does not cover the supply of services to the air lock from beyond the defined prEN 12110 1:2023/prEN 16191:2022 interface. This interface is set out in the text.
Vibration, noise and EMC (Electromagnetic compatibility) hazards are not significant hazards for air locks.
The provision of mixed gas, air or oxygen is the responsibility of the user.
During transfer under pressure operations, the shuttle requires a fire suppression system, a climate control system, a power supply and a gas supply. Of these, the fire suppression system requires to be continuously connected and available for immediate activation. It is therefore considered to be part of the shuttle equipment covered by this standard as is the power supply. For the other two services only the capability to supply them is considered to be part of the shuttle requirements.

Tunnel boring machines - Air locks - Part 1: requirements for air locks utilising compressed air as the pressurising or breathing medium along with requirements for oxygen breathing systems for decompression purposes
oSIST prEN 12110-1:2023

This document applies to the design, construction, equipping, marking and testing of air locks, as defined in 3.3, which form an integral part of a tunnel boring machine. It covers requirements for personnel locks utilizing compressed air as the pressurizing or breathing medium along with requirements for oxygen breathing systems for decompression purposes. The intended use is restricted to the temperature range 5 °C to 50 °C.
This document also applies to the design, fabrication and testing of pressure bulkheads intended for use in forming in-tunnel or in-shaft air locks.
In addition, this document extends to control functions and control information relating to intermediate chambers (defined in prEN 12110-2:2023, 3.7) (if fitted) but which are accessed via the personnel lock control panel.
prEN 12110-2 sets out additional requirements to those in Part 1, for personnel locks which are intended to have the capability to utilize non-air breathing mixtures such as nitrox, trimix and heliox. prEN 12110 2 sets out additional requirements for personnel locks intended to be used for saturation exposure techniques at pressures not exceeding 20 bar(g) associated with tunnelling work. It also sets out requirements for pressurized transfer shuttles as defined in 3.3.5.
The intended use of the machinery is agreed between the manufacturer and the user taking into account information on intended use, intended location of use, intended exposure techniques and intended decompression procedures, all provided by the user.
Air locks are normally connected to or incorporated in tunnel boring machines and consequently there are a number of interfaces between machinery covered by this standard and machinery covered by prEN 16191:2022. These interfaces are identified in both standards as appropriate.
This document is not applicable to machinery and equipment which is manufactured before the date of publication of this document by CEN.
NOTE 1   Air locks can be formed by the construction of one or more bulkheads in a tunnel secured to the tunnel lining. However, although the equipment required for tunnel air locks will be similar to that for TBM air locks, prEN 12110-1:2023 applies only to the design, fabrication and testing of bulkheads in this situation.
NOTE 2   Air locks can also be attached to an air deck in a shaft. Again, although the equipment required for such air locks will be similar to that for TBM air locks, prEN 12110-1:2023 applies only to the design, fabrication and testing of bulkheads (air decks) in shafts.
This document deals with all significant hazards, hazardous situations and events relevant to such machinery when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A).
The supply of compressed air and oxygen to the air lock is partly within the scope of prEN 12110-1:2023 and partly within the scope of prEN 16191:2022 and this division is clearly indicated within the text of both standards.
Vibration, noise and EMC (Electromagnetic compatibility) hazards are not significant hazards for air locks.

Requirements for air locks and pressurized transfer shuttles are covered by prEN 12110-1:2023 and prEN 12110-2:2023.
Hand-arm and whole-body vibration are not considered as significant hazards for tunnel boring machines.
The following items and applications are not covered by this document:
-   the additional requirements for the use of entire tunnelling machinery within a hyperbaric environment;
-   the additional requirements for use of tunnel boring machines in potentially explosive atmospheres;
NOTE 2    For the application in potentially explosive atmospheres, see EN ISO/IEC 80079 38:2016 for guidance.
-   ancillary tools and equipment which are not an integral part of the tunnel boring machine, but located on the machinery;
-   supply network for services to the tunnel boring machine (e.g. power supply, water, pipes, compressed air, ventilation duct, etc.);
-   loading and transport machinery which is not an integral part of the tunnel boring machine, e.g. delivery vehicle for logistic support, tunnel spoil removal system;
-   EMC interactions between the tunnelling machinery and third-party surface and underground assets, e.g. railway signalling.
This document is not applicable to tunnel boring machines which are manufactured before the date of publication of this European Standard by CEN.
