PREAMBLE

This Overall Safety and Health Protection Plan (PGCSPS) has been drawn up in the framework ofthe LHC project for the dismantling of LEP and the LEP experiments, the installation of the LHCand the LHC experiments and for the construction and adaptation of the infrastructure andequipment, in accordance with CERN regulations.

It takes into account the spirit of French and EU legislation and Swiss trends with regard to healthand safety coordination, and aims to harmonise the measures relating to health, safety andconditions in the workplace and thus limit risks and prevent occupational accidents and illnesses.

In agreement with the Host States and without prejudice to its international status, CERN complieswith the fundamental standards enshrined in the various national regulations. However, as anintergovernmental organisation with international status, CERN cannot be subject to any nationalprovisions, such as administrative and penal provisions, which would contradict its internationalstatus.

The contents of this PGCSPS shall in no way alter the nature or scope of the responsibilitiesincumbent upon the contractors, project managers and specialised bodies, pursuant to the legal andstatutory provisions concerning health, safety and conditions in the workplace to which they aresubject. This document is part of the call for tenders file sent to all contractors, includingsubcontractors and independent traders, since the provisions contained herein may have an impactin particular upon the amounts to be invested for the performance of the work.

The contents of the PGCSPS shall constitute basic data for the contractors, who shall use it to drawup their Special Safety and Health Protection Plan (PPSPS). The PGCSPS is a contractualdocument for the contractors and their subcontractors.

The PGCSPS will be completed and updated by the SPS Coordinator as the design studies and workprogress; it will also include addenda relating to specific operations for the LHC project (seeChapter 10 below). Furthermore, the PGCSPS will gradually incorporate and harmonise the PPSPSdrawn up by the contractors.

1. General information

1.1 CERN and its purposes

CERN (European Organization for Nuclear Research) is an intergovernmental laboratory, foundedby a number of European States on 29 September 1954. It currently has 19 Member States: Austria,Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Italy,Netherlands, Norway, Poland, Portugal, Slovak Republic, Spain, Sweden, Switzerland and theUnited Kingdom.The Organization has its seat in Geneva and sites totalling 550 hectares on either side of the borderbetween France and Switzerland.CERN’s purpose is to conduct fundamental research in particle physics, the field of theinfinitesimally small. For this purpose it designs, builds and operates high-energy particleaccelerators and, in collaboration with participating institutes, builds and installs the large detectorsrequired for the research.CERN hosts and provides technical support for around 5,000 scientists who come to work on theinstruments placed at their disposal.In collaboration with representatives from Europe’s universities and high-energy physics institutes,CERN organises the selection process for the experiments to be performed using its facilities anditself plays an active role in the research.Since it was founded, CERN has built a number of accelerators and collider rings. The mainfacilities currently in operation are:- a 28 GeV proton synchrotron, known as the PS,- a 450 GeV proton synchrotron, known as the SPS, which also has an antiproton source and canthus operate as a proton-antiproton collider,- an accelerator ring, known as LEP, for producing electron and positron collisions which, aftersuccessive stages of operation at various energies, is scheduled to reach an energy of 100 GeV perbeam.

1.2 The LHC project

The Large Hadron Collider (LHC) is a particle accelerator that will plumb the depths of matter to adeeper level than ever before.It is scheduled to come into operation in mid-2005 and will eventually produce proton beamcollisions at an energy of 14 TeV. Beams of lead nuclei will also be accelerated and brought intocollision at an energy of 1150 TeV.Keeping the LHC beams on their trajectory will require far more intense magnetic fields than thoseused for CERN’s previous accelerators.This will be achieved by superconductivity, at a temperature of minus 270°C. The LHC will beinstalled in the same tunnel as CERN’s Large Electron Positron collider, LEP.This project, approved by the CERN Council in December 1994, is a major new step in CERN’sdevelopment, and will use much of the infrastructure left behind by the LEP collider it will bereplacing.Nonetheless, construction of the LHC will call for extensive modifications to existing structures,installations and equipment, as well as many new surface and underground structures.Work is to be performed on sites in operation (at least until October 2000) and will include thedismantling and/or modification of several existing structures, installations and facilities at thesurface and underground.

1.3 Summary of the work

As a whole, the work for the LHC project comprises:– The dismantling of LEP in sectors 1-2, 2-3, 3-4, 4-5, 5-6, 6-7, 7-8, 8-1– The dismantling of the ALEPH, OPAL, DELPHI and L3 experiments– The installation of the infrastructure and equipment in the surface buildings concerned (Points

1, 1.8, 4, 5, 6, 8)– The installation and adaptation of the infrastructure and equipment associated with the

underground facilities– The assembly of the ATLAS, CMS, LHC-b and ALICE experiments– The installation of the LHC in all sectors.

Work must start in the second half of 1999, with the general services, fluids and ventilation of thesurface buildings at Point 1, and will continue through to mid-2005 when tests of the wholecomplex will begin (see attached project schedule).

1.4 Monitoring of progress and technical coordination

An overall coordination scheme has been set up to ensure the work is conducted under the righttechnical conditions and with proper regard to safety. Responsibility for this task has been delegatedto CERN’s AC/DI group. Responsibility for progress monitoring and technical coordination of thevarious items of work has been shared between CERN groups as follows:– Installation of the infrastructure and equipment in the new surface facilities: coordination by the

AC/DI group– Dismantling of LEP, machines, equipment and installations both at the surface and

underground: coordination by the SL/MR group– Dismantling of LEP experiments: coordination by the EST/LEA group and the various EP

groups concerned– Installation of the infrastructure and equipment in the new shafts: coordination by the AC/DI

group– Installation of the infrastructure and equipment in the new experiment halls: coordination by

the EST/LEA group and the various EP groups concerned– Installation of the infrastructure of the LHC machine and the accelerator itself: coordination by

the AC/DI - SL/MR groups– Assembly of the experiments in the experimental areas: coordination by EST/LEA and the

various EP groups concerned.

1.5 Geographic location of CERN installations

CERN’s installations are located on either side of the French-Swiss border on a number of sites inMeyrin (Switzerland) and in several “communes” within the District of Gex (France).The infrastructure in these sites includes:At the surface:– Laboratories, experiment halls, drawing offices, workshops, production or fluid processing

plants, administrative buildings and services such as restaurants, banks, hostels, etc.Underground:– The PS, SPS and LEP particle accelerators, that are used to conduct fundamental research

experiments into the ultimate structure of matter.A map showing the layout of CERN’s various installations is appended to this PGCSPS.

This document is included at each call for tender constitutes anintegral part of the PGCSPS; it will hereinafter be referred to as “the Safety Regulations”.With respect to SPS coordination, CERN undertakes, as Principal, to follow a policy of preventionthroughout all the phases of the project, from design through to construction; to this end, it willcomply, in particular, with– European Directive 92-57 EEC of 24 June 1992– French law 93-1418 of 31 December 1993 and its associated implementing decree 94-1159 of

26 December 1994This document also takes into account all regulations relating to safety in the workplace currently inforce in the Host States, which must be fully adhered to.

1.8 Aim and role of the SPS Coordinator

The essential aim of the SPS coordinator is to perform the following tasks:– to provide all necessary assistance with respect to health and safety to all the partners involved

in the LHC project and to ensure that the general principles of prevention and other regulationsare observed at all stages of the project;

– to draw up the PGCSPS, defining the measures specifically relating to the prevention of risks,in particular those deriving from interference between the activities of different contractors on


13

the work sites. This document, drafted during the design, design study and preparation phase ofthe project, will be included with the call for tender documents sent to potential bidders andwill serve as the basis for the preparation of the PPSPS by successful bidders;

– to draw up the DIUO, which sets out the measures chosen to facilitate later work on eachstructure (safety of repair and maintenance teams);

– to keep the RJ;– to chair the CISSCT that will be set up by CERN.

In particular, the coordinator will:– update the PGCSPS and ensure that it is observed;– make a joint inspection of the site with all the contractors, in the presence of the project

manager, before any work is done and before the PPSPS is submitted; during this inspection,information will be given on the various instructions to be complied with or to be passed on tothe workforce, according to the work to be performed, as well as any specific remarks relatingto health and safety for the whole operation;

– take account of the interferences and constraints inherent in the performance of the work andinform the contractors of the measures to be taken;

– ensure compliance with the decisions taken on safety problems at the various meetings andinspections, in particular those taken at the CISSCT and during joint inspections;

– inspect the work site and report any instances of non-compliance with the safety measuresspecified by the regulations in force or imposed on the contractors by the Principal, projectmanager and the SPS Coordinator;

– examine with the contractors the measures and provisions to be taken to implement the generalprinciples of prevention ;

– advise all appropriate measures to promote workers’ health and especially those aimed atpreventing occupational illnesses;

– receive the PPSPS from the contractors, examine their contents, communicate any observationshe or the project manager wish to make and ensure these are brought to the attention ofeveryone concerned;

– coordinate safety measures taken or to be taken by contractors working in succession orconcurrently on the work site, including subcontractors;

– keep the RJ up-to-date;– receive personal accident reports and conduct investigations in the event of serious accidents;– compile, update and analyse accident statistics;– ensure the DIUO is updated.

2. Specific features of the working areas

2.1 Surface buildings and areas

Compared to conventional surface facilities, the CERN site has the following special features to betaken into account: – shafts – storage areas – large handling areas – access for the Fire and Rescue Service in the event of incidents or accidents.

2.1.1 Shafts

2.1.1.1 Existing shafts The presence of shafts essentially entails a risk of objects or persons falling from a height. Thecollective protective measures must therefore be kept in place and nothing must be stored within aradius of 1.5 metres around the shaft. Authorisation for the removal of a safety installation may onlybe given by the site manager. Collectives protections may only be removed if the hazardous area is properly marked out by thecontractor concerned. Any staff entering the hazardous area shall be equipped with individual harness-type safety gear toprevent them from falling, and shall put the original safety installation back into position uponcompletion of their work.


20

Opening the lower part of the aperture in the existing SD buildings, at the even-numberedpoints, is authorised if absolutely necessary for the purpose of handling bulky components. Theaperture must be opened according to the following procedure: – 1 - The member of ST/HM group in charge of the transport operation, who is in possession of

the key to the first lock, shall contact the site manager and they shall proceed together to theshaft-head.

– 2 - The site manager shall unlock the second lock. – 3 - The member of the ST/HM group in charge of the operation shall open the lower panel only

to let the load through, check that the indicator light is working and lock the panel againimmediately afterwards.

– 4 - When the operation has been completed, the member of the transport group in charge shallask the site manager to secure the second lock and shall remain at the shaft-head until this hasbeen done.

This procedure shall be applied as soon as the handling work has been completed and at the end ofthe day, even if work is scheduled to resume the following day.

2.1.1.2 New shafts Pending the installation of permanent shaft-head barriers, the barriers set up by the civil-engineeringcontractors shall remain in place, for a transitional phase, after acceptance by the AC/DI group andagreement from the SPS Coordinator. The shaft-head safety barrier shall be at least 2 m in heightand strong enough to withstand impact from the plant operating in its vicinity. Furthermore, the contractors shall make specific arrangements to allow entirely safe access to theflying or sliding scaffold platforms (for work inside the shaft). As is the case for existing shafts, nothing shall be stored within a radius of 1.5 m around the shaft.

2.1.2 Storage areas The main hazards for personnel in storage areas are falling objects and the risk of personnel fallingfrom grade level. Storage and plant manoeuvring areas shall therefore have clear ground markings,provided by CERN. The person in charge of transport operations and the site manager shall checkthat these instructions are obeyed. No equipment shall be stored in the storage areas without the agreement of the site manager, withwhom the contractor shall liaise before any delivery.

2.1.3 Handling areas The main hazards associated with handling are falling loads and moving plant. It is forbidden forloads to be transported over the heads of staff and for vehicles to park or pass underneath loads.Moreover, when handling machines are being used, their area of manoeuvre shall be clearly markedand, if necessary, all manoeuvres shall by supervised by someone appointed by the person in chargeof the operation.

2.1.4 Fire and Rescue Service access areas To facilitate the arrival of the Fire and Rescue Service, each shaft has an area designated by CERN(marked out on the ground) to allow access for emergency vehicles without the need to evacuate thestorage or other areas.

2.2 Shafts and shaft bottoms

The specific hazards associated with these areas are essentially: – people or equipment falling – fire.


21

2.2.1 The risk of falls The shafts are provided with infrastructure for totally safe access. For the special case of new shafts,where there is no permanent infrastructure allowing staff access, the temporary lifts shall be used.Safety installations at shaft bottoms shall remain in existing shafts and installed in new ones.

2.2.2 Fire hazards Due to the strong updraft in the shafts, even small fires can quickly take on major proportions.Contractors are therefore required to keep their workplaces clean at all times. Rubbish skips areprovided for this purpose and are emptied every day. The site manager shall pay special attention to ensuring the work sites are kept clean.

2.3 Underground facilities

The specific hazards associated with work in underground facilities are: – fire and being overcome by smoke and fumes – anoxia – traffic hazards – exposure to ionising radiation (notably during the dismantling of LEP and the LEP

experiments).

2.3.1 Fire hazards and the risk of intoxication from smoke and fumes Given the size of the facility and the great distances to be covered to evacuate a hazardous area, fireis a major hazard in the tunnels, especially due to the resulting emission of smoke and fumes. In the tunnels the following principles of fire prevention shall apply: – prevent fires from breaking out – take precautions against smoke and fumes – sound the alarm.

2.3.1.1 Preventing fires from breaking out The same principles of cleanliness shall apply as for the shafts and shaft bottoms, with the followingadditional provisions: – Smoking is strictly forbidden in underground facilities. – Hot work permit: Any contractor undertaking hot work shall apply to his supervisor for a hot-

work permit, which shall define the nature of the work, the hazards, the preventive measuresand the planned means of protection.

– Equipment prohibited in tunnels: In view of fire and smoke hazards, all gas-heated devices andinternal combustion engines are prohibited in the tunnels. Propane preheating torches forwelding and gas heaters, etc., are also prohibited.

– Compressed air: Should compressed air be required, only electrical compressors shall beallowed in the tunnels or caverns.

– Gas bottles: Authorisation shall be required from the CERN supervisor for compressed gasbottles to be taken into underground facilities. The contents shall be clearly marked on eachbottle. Bottle trolleys shall be used at all times.

– Fire extinguishers: As a means of preventing a small fire from spreading, CERN will provide anumber of fire extinguishers in addition to those already in place. Fire extinguishers shall not behandled without a proper reason. Any fire extinguisher that suffers an impact, whether it hasbeen used or not, shall be reported to the site manager, who will notify the TIS/FB group (Fireand Rescue Service).

2.3.1.2 Prevention against smoke and fumes: Smoke and fumes constitute a major intoxication hazard for staff. Unless the Fire and RescueService instructs otherwise, the ventilation shall remain in operation even in the event of a fire. Itshall only be shut down at the Fire and Rescue Service’s request.


22

Individual protective gear: In order to cope with accidental smoke emissions, CERN will providepersonnel with escape breathing apparatus providing 30 minutes of oxygen supply (at the shaftbottoms and in the transport vehicles used in the tunnels). The procedure for handling these devices will be explained at the safety briefing organised byCERN. Personnel working in tunnels or caverns shall keep this equipment close to hand. It is up to the contractors to organise their work site in a such a way as to comply with theseinstructions. Access to underground facilities shall not be granted to those equipped with faulty safety gear or nosafety gear at all. The contractor’s site representative, the site manager, the members of the TISCommission and the SPS Coordinator shall ensure that this rule is observed.

2.3.2 The risk of anoxia Anoxia is caused by the reduction of the oxygen level in the air. The general principle of preventionagainst such a hazard is to maintain constant ventilation inside the underground facilities. This isachieved by injecting fresh air via the even-numbered shafts and extracting it via the odd-numberedshafts. The risk of anoxia will arise in special circumstances where a ventilation system shutdowncoincides with the emission of an inert gas (warning given by evacuation alarm). In this particularcase, staff will be equipped with gas masks and must proceed directly to the pressurised chamber atthe shaft bottom.

2.3.3 Transport hazard

2.3.3.1 Transportation by monorail: The monorail may be driven only by specialised personnel approved by CERN who shall havereceived training and strict instructions on driving the monorail. The monorail’s design speed in areas of high personnel density (US, UL, UA, RA) is limited to50 m/min; in addition it is fitted with a bumper that activates the safety brake in the event ofcollisions. Other provisions will be envisaged after LEP has been dismantled and before the LHC isinstalled.

2.3.3.2 Transport by self-propelled electrical vehicles Equipment storage areas: whatever the circumstances, each contractor shall leave a floor-levelthoroughfare of at least 90 cm at his work site and equipment storage areas to allow access for theself-propelled vehicles needed for the work sites and emergencies. For this purpose he shall: – mark out equipment storage areas, – install warning signs on both sides of these storage areas, – allow free access by leaving an adequate thoroughfare, as specified above.

2.3.4 Radiation hazards (exposure to ionising radiation) The principles governing the protection of people, classification of working areas and radioactivematerials, and protection of the environment are set out in the Radiation Safety Manual issued bythe TIS/RP group. The Radiation Safety Manual may be obtained from the TIS/GS group or the TIS/RP group. Work involving the exposure of personnel to ionising radiation will be indicated in thecorresponding addenda, to which the specific instructions to be observed will be appended.


23

3. Organization and coordination measures

3.1 Working hours and official holidays

Except in special cases, work shall be done in CERN’s normal working hours, i.e. between 7.30a.m. and 5.30 p.m. Special cases: – Work on underground work sites shall be done either during normal working hours or in

staggered shifts; to avoid bottlenecks in the lifts, controlled access points and transportationsystems, CERN will specify the working hours for each trade or even for each work teamwithin a time band running from 5.00 a.m. to 9.00 p.m.

– If the work schedule so dictates, contractors may have to work at night (10.00 p.m. to 5.00 a.m.)and/or on Saturdays.

For any work that has CERN’s prior authorisation to be performed outside normal working hoursand days, i.e. between 5.00 p.m. and 7.30 a.m., at weekends and on official holidays, a formalrequest shall be submitted using the attached form “Avis d’exécution des travaux en dehors desheures et jours ouvrables du CERN“ (Notice of the performance of work outside normal CERNworking hours and days). The completed form shall be distributed as shown on the back of thedocument itself, and the contractor shall ensure that he has obtained the prior consent of the nationalauthorities. CERN’s official holidays are: – 1st January – Good Friday – Easter Monday – 1st May – Ascension Thursday – Whit Monday – the “Jeûne Genevois” (Thursday following the first Sunday in September) – 24th and 25th December. – 31st December In addition, CERN closes down for two weeks between Christmas and the New Year. During thisperiod, CERN can provide only a minimum level of work-site surveillance and the work sites willbe closed unless it is an absolute necessity for them to continue. Contractors are urged to take annual leave during this period.

3.2 Radioactivity: instructions by working area

3.2.1 Definition of working areas Working areas are classified and instructions defined according to the risk of exposure on the basisof the dose rates measured by the CERN Radiation Protection Service. The classification of areas bydose rate is as follows (natural background not included):

Areas Average dose rate Maximum dose rate Non-designated � 0,15�Sv/h � 0, 5�Sv/h Supervised � 2,5�Sv/h � 7,5�Sv/h Simple controlled � 25�Sv/h � 100�Sv/h Limited stay �2mSv/h

High-radiation �2mSv/h

Prohibited �100mSv/h


24

3.2.2 Provisions concerning working areas

3.2.2.1 Non-designated areas The doses received by persons in such areas remain below the public exposure limits. Compliancewith dose limits for non-designated areas will be monitored by means of active and passivedosimetry systems.

3.2.2.2 Supervised areas Access to these areas is free and there is no restriction on the length of stay or the duration of work.Ionising radiation in these areas is monitored on an annual basis by means of active dose-ratemeasurements combined with integrated dose-rate measurements (passive detectors).

3.2.2.3 Simple controlled areas Persons having to work in a simple controlled area must be subject to personal dosimetrymonitoring, and are required to wear personal dosimeters throughout each stay in such areas. Theduration of stay in a simple controlled area is limited only by the ALARA principle, as peopleworking there under normal circumstances receive doses of less than 15 mSv per year.

3.2.2.4 Limited stay areas Access to limited-stay areas is restricted to staff under personal dosimetry monitoring, who mustwear their personal dosimeters. They are also required to wear special dosimeters provided by theTIS/RP group, as shown on the warning signs. Work in such areas requires authorisation from theRadiation Safety Officer (RSO) or the RP group.

3.2.2.5 High-radiation areas High-radiation areas are closed off by rigid barriers, and access doors are locked when thesupervisor is absent. In the event of a highly radioactive object being transported, the divisionconcerned shall erect temporary barriers and station a guard to prevent unauthorised access. The same conditions of access as for limited-stay areas shall apply. In addition, each person wishingto access such areas shall require authorisation from the RSO or the RP group. Access to areaswhere the dose rate is higher than 2 mSv/hour is forbidden to occasional visitors and temporarystaff.

3.2.2.6 Prohibited areas These areas are closed off in such a way as to make it physically impossible to enter, even usingspecial equipment. Under exceptional circumstances a Division Leader may authorise persons withthe prior consent of the Medical Service and the RP group to access a prohibited area. Both theaccess and the work shall be permanently monitored by the RP group.

3.2.3 Reference documents The installation of warning signs in working areas is governed by document TIS-RP- PRP1a.doc.In addition, the rules governing the monitoring of ionising radiation on any item likely to beactivated are set out in document TIS-RP-PRP28a.doc. The rules for the transport of radioactive materials between the various parts of the CERN site arelaid down in document PRP29a.doc. All these documents may be obtained from the RP Group.

3.3 Systems and services remaining operational to ensure safety during work inunderground facilities

3.3.1 General provisions The following systems shall remain in operation: – general ventilation of the tunnel (including smoke removal)


25

– industrial and fire-fighting water supply network (embedded in the concrete floor of the tunnel) – existing general drainage system (including waste-water pumping system) together with the

following: – level-3 alarm network, including: the smoke, gas and flood detection systems, “red telephone”,

evacuation alarm activator, lift immobilisation alarm (the level-3 alarm system relates to alarmsset off due to an accident or a malfunction that endangers or might endanger human life andresults in the immediate departure of the Fire and Rescue Service; interventions by the Fire andRescue Service are usually followed by action from the technical services).

– the G S M network – the 400 V supply network including the no-break network, the emergency lighting network and

utilities. The access control system, including video-monitoring of the site and the site and shaft accesscontrol systems shall also remain in operation.

3.3.2 Ventilation of underground facilities The ventilation of underground facilities during the LEP conversion work and the installation of theLHC and the LHC experiments will be the responsibility of CERN (ST/CV). In the tunnelventilation system, air is injected via the even-numbered shafts and extracted via the odd-numberedshafts. The air-handling facilities are designed to renew the air twice an hour (all fresh air) for health andsafety purposes; the air renewal rate may be increased to 4 volumes/hour in order to evacuate smokeand fumes in the event of an emergency. Contractors whose work generates dust, vapour, toxic gases, smoke or fumes shall take all necessarymeasures to facilitate treatment, capture and discharge. In the event of a lengthy ventilation shutdown, the ST/CV group will inform the site managers, whoshall have the underground facilities evacuated.

3.3.3 Lighting The emergency lighting in the shafts, tunnels and experiment halls will remain in operation for theLEP conversion work. There are four lighting circuits, classified according to their level of safety: Normal lighting from the general services LV networks: this network supplies the general lightingcircuits for all the underground facilities and surface buildings. In new facilities, temporarymeasures will be taken to ensure work stations are illuminated until the permanent lighting isinstalled. No-break lighting from the no-break general services network: this network supplies the no-breaklighting for underground facilities not requiring ambient lighting, for the machines, the injectiontunnels and for the klystrons. Emergency lighting: this system supplies the emergency lighting circuits from inverters, themselvessupplied by the 48V batteries provided in the safety rooms. Ambient safety lighting, supplied by the LV safety network connected to generator sets, via anisolating transformer installed in the safety room. If necessary, the contractors shall provide additional lighting for their work stations such as tocomply with the rules governing safety and conditions in the workplace.

3.4 Personnel and equipment access conditions

3.4.1 Personnel access to the CERN site The conditions of access to the CERN site (personnel and vehicles) are described in documentDSU-DO/RH/1845, entitled “CONTRACTORS AND THEIR STAFF: ACCESS TO ANDACTIVITIES ON THE CERN SITE“, that can be obtained on request. Contractors shall obtain the necessary authorisations from the relevant Host State authorities toenter France or Switzerland.


26

In order to obtain a personalised access card staff must attend a reception meeting, as specified inAnnex 6 of the “Safety Regulations”.

3.4.2 Access control Access to the LEP sites will be controlled; site entrances and access shafts to the underground areashave magnetic strip card readers. The site entrance and underground access barriers are opened byintroducing the personalised access card into the reader. This access control system has been set up for safety reasons, enabling the safety services to monitorthe identity and number of people underground at all times. For the new shafts (at Points 1 and 5 in particular), similar provisions to control access to theunderground areas will be made.

3.4.3 Transport of personnel in the tunnels CERN is responsible for all personnel transport systems in the structures. Personnel working within500 m of the access point shall go on foot; for longer distances a vehicle will be provided at thebeginning and end of the shift. In certain cases, the contractors’ team leaders shall be provided with a self-propelled electricalvehicle. These vehicles are designed to carry one person and their allocation to contractors shall bedecided by the ST/HM group and the site manager . Contractors shall be entirely responsible for anyvehicles with which they are entrusted, and it shall be up to them to select the drivers and to keepthe batteries charged. The maximum distance to be covered from the lift to the place of work is 3300 m. Assuming anaverage journey of 1650 m (the initial 500 m can be covered on foot), the average time lost perjourney is around 15 minutes, to which should be added approximately 5 minutes for the turnaroundtime of the access lift.

3.4.4 Conditions of supply of the various work sites Transport of equipment and materials for surface installations: – The contractors shall be responsible for all transport to their own premises or to the surface

areas (surface buildings around the access points or buffer storage areas). Transport of equipment and materials in the underground facilities: – All equipment to be transported to the underground facilities shall be handled by the CERN

transport service from the relevant access shafts onwards. The quantities of equipment and thetransport dates shall be defined in agreement with CERN’s ST/HM group. The same rule shallapply to transport from the underground facilities to the surface.

3.5 General conditions of handling and transport

Except in special circumstances, CERN’s ST/HM group (or personnel authorised by CERN) will beresponsible for handling in the surface buildings, shafts and underground facilities for the purposeof transporting equipment to its place of use or storage. For this, CERN (or personnel authorised byCERN) will use the existing equipment, namely: monorails, overhead travelling cranes, trolleys, etc. The use of handling machinery by contractors is subject to prior presentation of a certificate ofconformity with the Safety Regulations. Concerning the organisation of buffer storage areas at the surface or plant installation areas etc.,handling procedures will be drawn up (by CERN), specifying in particular: – the characteristics of the equipment in terms of radioactivity – the resulting handling sequences and conditions – the surface area required for temporary storage, removal of items and handling machinery

manoeuvres – the estimated duration of the buffer storage.


27

3.6 Conditions of handling, storage and transport of radioactive components

It should be noted that material is considered radioactive once the dose rate 10 cm from its surfaceexceeds 0.1 �Sv/h after deduction of natural background. Any radioactive object or source present on the CERN site, or which enters or leaves it, is subject tothe rules laid down by the TIS/RP section, namely: – Rules to be followed for checking radioactive material (PRP28a.doc) – ”Sources et matériaux radioactifs” (radioactive sources and materials - PRP25a.doc) – Transport of radioactive material between the various sites (PRP29a.doc) – ”Procédure concernant les demandes d’expédition des matières radioactives” (Procedure for

requests to dispatch radioactive material - PRP13a.doc) – ”Procédure de radioprotection relative au matériel de récupération” (Radiation safety procedure

relating to salvaged material - PRP7a.doc). These rules and procedures are available from TIS/GS or the SPS coordinator.

3.7 Conditions of waste removal

Aside from bulky items of waste, which will probably be packed up and removed, contractors willbe provided with waste skips at the surface, at the shaft bottoms and at certain points in the tunnels.For fire safety reasons, skips will be removed from the underground areas once a day.

3.8 General safety measures

All the provisions set out in the “Safety Regulations” are applicable and in particular with respect tothe following points:

3.8.1 General safety installations at access points and work stations Measures shall be taken to protect workers from objects falling from a height, and all suitable meansshall be deployed to prevent objects from falling. The existing measures shall be maintained and, should this prove impossible, compensatorymeasures shall be taken. General safety installations already in place or set up temporarily may onlybe dismantled with the agreement of the works supervisor and the SPS Coordinator. It is particularly important to maintain general safety installations in “sensitive areas” such as shaftheads and bottoms, work platforms set up on fixed or mobile scaffolding and work areas at a height,etc.

3.8.2 Scaffolds (fixed, mobile, flying) and telescopic boom lifts Prior authorisation is required from the SPS Coordinator to install scaffolds or telescopic boom lifts. On the French part of the site, scaffolds shall comply with the provisions of the Decree of 8 January1965, as amended by the Decree of 6 May 1995, and on the Swiss part of the site with CantonalWork Site Regulation L 5 05 03. In the particular case of fixed scaffolds with cantilevered or overhanging sections, a scaffoldassembly drawing with design memoranda showing the stability of the structure shall be prepared.Floors shall be made of jointed materials that are incombustible or very difficult to ignite. CERN reserves the right (through its safety officers) to have any structure that does not comply withthe safety requirements specified above dismantled, re-erected or modified. The type and capacity of telescopic boom lifts and aerial work platforms will depend on the workto be done, and the choice will take into account the number of workers to be conveyed, the weightof the workpieces to be raised, the elevation, etc. They shall preferably be of the electrical type andmust have been checked by a qualified body before being used on each work site. Any motorised flying scaffolds used for installation work in the shafts shall comply with thefollowing main provisions:


28

* maximum length may be greater than 8 metres upon submission of drawings and designmemoranda; peripheral safety barriers shall consist of a hand-rail at 1.10 m, an intermediate rail at0.45 m and a 0.15 m skirting board.

* each of the two main suspension cables shall be fitted with: – an automatic fall-prevention device on the platform connected to the independent safety cable

of the main suspension cable, – a slack detection device to halt the platform’s descent if it becomes entangled with an

overhanging part of the structure. – a strain limiter on the cable to prevent entanglement while the platform is rising,– end stops at the top and bottom.

The cable winches must be controlled simultaneously. The controls must have a lockable “stop”position and an emergency stop function. A panel showing the maximum load and evacuationinstructions in the event of accidental stop shall be fitted to the platform. This type of equipment must be checked every 6 months at least and each time it is put into orresumes operation. The results of inspections, checks and tests must be logged in a register with thenames and title of the persons who conducted them.

3.8.3 Ladders A ladder is a means of access to a higher level and its use as a work platform is prohibited. Itmust be secured at the top and bottom to prevent it from sliding or tipping over and must be 1 mhigher than the level to which it provides access.

3.8.4 Compulsory individual safety gear It must be noted that, independently of the general safety measures in force, the wearing of a helmetis compulsory on all the worksites of the LHC project. The following safety measures are also compulsory:� The wearing of safety shoes,� The wearing of a safety harness for all short-term (• 1 day) work at a height where there are no

collectives protections to prevent falls,� The wearing of a mask (for filtering aerosols, gases or dust, as appropriate) and safety goggles

for all work involving grinding, painting or the use of dangerous substances,� The wearing of gloves for work involving the handling or use of dangerous substances,� The provision of escape breathing apparatus.

3.8.5 Welding and grinding work For welding, grinding and sawing, etc., a hot-work permit issued by the supervisor is required. Thispermit, which must be initialled by both the supervisor and the contractor concerned, must beforwarded to the site manager and the SPS coordinator for information. These hot-work permits are valid for one day or one week according to the environment of theworksite concerned. Both the site manager and the SPS coordinator may stop any hot work in caseswhere the operator is not in possession of a hot-work permit or in the case of failure to comply withthe rules. In addition to taking fire precautions, the contractor shall install the necessary safety devices toprotect passers-by against stray flashes, flying particles, drips, etc. The preferred method for theevacuation of smoke and fumes is by capture at source and evacuation to the ventilation system orto the exterior, or else by means of extractor hoods fitted with active carbon filters. During electric welding the earthing shall be provided directly by the items to be welded. The use offrames, guard-rails, etc., as the earth return is forbidden. Each welding station must have a flame-resistant insulating container where scrap from the welding rod or filler metal and the welding guncan be deposited.


29

3.8.6 Compressed gas bottles The safety rules concerning the supply and use of flammable gases and the design and use ofsystems using flammable gases are set out in safety code G (CERN Safety Manual, FlammableGases) and, in particular, in Safety Instruction 42 which deals with the rules governing the use of(flammable or non-flammable) compressed gas bottles. These documents are available from the TIS/GS Group.

3.8.7 Electrical portable tools The hand tools used shall be suitably insulated and shall have the appropriate protection rating andelectricity supply. They shall comply with the standards in force in the Host States.

3.8.8 Machines Machines other than manually operated machines and portable electrical or pneumatic equipmentare not allowed in the underground areas. Should the use of such machines inside the LEP premises prove absolutely necessary, exceptions tothis rule may be granted only by the TIS division and the SPS coordinator together. The personnel using this equipment must have the necessary authorisation and the user must presenta statement of compliance with the documents in force.

3.8.9 Working environment and conditions Noise, dust, smoke and fumes are significant pollution agents in the underground areas. Wherever possible, noise reduction at source (sound-proofed equipment) shall be required. Wherethe noise is caused by the activity itself, the work shall be done outside wherever possible(hammering, sheet-metal work, etc.). Failing this, the area concerned shall be delimited and thepersonnel concerned given the appropriate equipment. Activities involving the production of dust, smoke or fumes shall preferably be dealt with bymeasures such as capture and extraction of dust and/or smoke and fumes at source or the use ofdust- and smoke-filtering equipment. These preventive measures are also applicable in the surface buildings.

3.8.10 Worksite inspection visits All visits by persons not involved in the work on the LHC project shall require prior authorisationby the project manager.

3.8.11 Information and training of the personnel concerned

3.8.11.1 Information Prior to performing any activity on the worksite, the personnel must be informed by theirhierarchical supervisors of the specific conditions relating to work on the site, namely:� Conditions of access to the various worksites applying to the personnel� Conditions of supply� Staging and procedures applying to the various items of work� Hazards specific to the working environment and preventive measures� General safety measures� Emergency plan.

These items shall be discussed with the company's senior representatives during the joint inspectionvisit organised by the SPS coordinator.

3.8.11.2 TrainingIn the case of personnel working in a controlled area (where radioactive substances are present)and/or in a non-controlled area (where radioactive substances have been produced) and/or handlingmaterial classed as very weakly radioactive, specific radiation protection training will be needed.This training will cover all measures designed to ensure the protection of people and theenvironment against the hazards associated with ionising radiation.

4. Special requirements arising from the hazards due tointerference between different activities Bearing in mind possible interactions with civil-engineering work in particular, the boundariesbetween areas where civil-engineering work is being carried out and those of other work areas mustbe clearly marked by suitable fencing, markers and signs. The rules governing the movement of thepersonnel of the various contractors will be defined by those in charge of the civil engineering, theother work and the SPS coordinator. During the dismantling work on LEP and its experiments and the installation of the infrastructuresof the LHC and its experiments, the various activities shall be carried out in accordance with theapplicable schedules so as to avoid any risks associated with simultaneous activities. Thecontractors' attention is drawn to the fact that there is a major risk of interference and overlapping inthe case of the various types of work involved in fitting out the shafts and they must not be donesimultaneously. However, it should be noted that delays in the work to be done might sometimes give rise tohazardous situations which must be taken into account in the changing and adjustment of the workschedules.

5. Fire: emergency plan
