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.
Tunnelbaumaschinen - Druckluftschleusen - Sicherheitstechnische Anforderungen
Dieses Dokument gilt für Form, Aufbau, Ausstattung, Kennzeichnung und Prüfung von Druckluftschleusen, wie in 3.3 festgelegt, einschließlich Druckwänden, wie in 3.4 festgelegt, die bei Tunnelbauarbeiten verwendet werden. Die zur Versorgung mit Luft eingesetzte Sauerstoffanlage, die für die sichere Durchführung einer Ausschleusung erforderlich ist, fällt ebenfalls in den Anwendungsbereich dieser Norm.
Dieses Dokument gilt nicht für Maschinen, die hergestellt wurden, bevor CEN dieses Dokument veröffent-lichte.
ANMERKUNG Druckluftschleusen können mit Tunnelbaumaschinen verbunden werden. Diese Norm kann helfen, Druckluftschleusen und Druckwände für andere Arbeiten unter Druckluft zu konstruieren.
Dieses Dokument behandelt alle signifikanten Gefährdungen, Gefährdungssituationen und Gefährdungsereig-nisse, die auf Druckluftschleusen und Druckwände zutreffen, wenn sie bestimmungsgemäß und entsprechend den vorhersehbaren Bedingungen des Herstellers verwendet werden (siehe Abschnitt 4).
Dieses Dokument behandelt nicht die Wartungsversorgung der Druckluftschleuse.
Gefährdungen durch Schwingungen, Lärm und EMV (Elektromagnetische Verträglichkeit) sind keine signifikanten Gefährdungen für Druckluftschleusen.
Dieses Dokument behandelt nicht die Gefährdungen auf Grund der Beweglichkeit der Maschine.
Machines pour la construction de tunnels - Sas de transfert - Prescriptions de sécurité
La présente Norme européenne porte sur la conception, la fabrication, la fourniture, le marquage et les essais des sas de transfert définis en 3.3 y compris les parois de cloison de pression définies en 3.4, qui sont destinés aux travaux de creusement de tunnels.
La présente Norme européenne ne s'applique pas aux machines et équipements qui ont été construits avant la date de publication du présent document par le CEN.
NOTE Les sas de transfert peuvent être connectés aux tunneliers. La présente norme peut aider à la conception des sas de transfert et des parois de cloison de pression pour d’autres travaux de construction sous air comprimé.
La présente Norme européenne traite de tous les phénomènes, situations et événements dangereux significatifs relatifs aux engins de terrassement lorsqu'ils sont utilisés comme prévu ou dans des conditions de mauvais usage que le fabricant peut raisonnablement prévoir (voir Article 4).
La présente Norme européenne ne couvre pas la fourniture de réparations au sas de transfert.
Les phénomènes dangereux engendrés par les vibrations, le bruit et la CEM (compatibilité électromagnétique) ne constituent pas des phénomènes dangereux significatifs pour les sas de transfert.
La présente Norme européenne ne couvre pas les risques dus à la mobilité des machines.
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.
