Tunnelling machines - Air locks - Safety requirements

Tunnelling machines - Air locks - Safety requirements

This European Standard applies to the design, construction, equipping, marking and testing of air locks as defined in 3.3 including pressure bulkheads as defined in 3.4, which are to be used in tunnelling work. An oxygen breathing system used to provide the breathing supply necessary to conduct a safe decompression is also covered by this standard.
This European Standard is not applicable to machinery and equipment which is manufactured before the date of publication of this document by CEN.
NOTE   Air locks can be connected to tunnelling machinery. This standard can help the design of air locks and bulkheads in other compressed air work in construction.
This European Standard 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 Clause 4).
This European Standard does not cover the supply of services to the air lock.
Vibration, noise and EMC (Electromagnetic compatibility) hazards are not significant hazards for air locks.
This European Standard does not cover the hazards due to the mobility of the machinery.

Stroji za gradnjo predorov - Zračne zapore - Varnostne zahteve

Standard EN 12110 se uporablja za zasnovo, konstruiranje, opremljanje, označevanje in preskušanje zračnih zapor, kot je opredeljeno v točki 3.3, vključno s hermetičnimi pregradami, kot je opredeljeno v točki 3.4, ki se uporabljajo v delih v predorih. Dihalni sistem s kisikom, ki se uporablja za zagotavljanje dovoda zraka za dihanje, potrebnega za izvajanje varne dekompresije, je prav tako obravnavan v tem standardu. Ta evropski standard se ne uporablja za stroje in opremo, izdelane pred datumom, ko je Evropski odbor za standardizacijo (CEN) objavil ta dokument. Ta evropski standard opisuje vsa večja tveganja, nevarne situacije in nevarne dogodke v zvezi s takimi stroji, kadar se uporabljajo v skladu z njihovim namenom in pod pogoji pričakovane nepravilne uporabe, ki jih določa proizvajalec (glejte točko 4). Ta evropski standard ne zajema zagotavljanja storitev do zračne zapore. Tveganja, povezana z vibracijami, hrupom in elektromagnetno združljivostjo (EMC), ne spadajo med večja tveganja za zračne zapore. Ta evropski standard ne obravnava tveganj zaradi mobilnosti strojev.

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.
