8、ember 2004 Foreword Technical Committee B/514/39 has prepared this part of BS 6037. This part of BS 6037 covers the planning, design, installation and use of travelling ladders and gantries. As a code of practice this British Standard takes the form of guidance and recommendations. It should not be
9、quoted as if it were a specification and particular care should be taken to ensure that claims of compliance are not misleading. It has been assumed in the preparation of this standard that the execution of its provisions will be entrusted to appropriately qualified and experienced people for whose
10、use it has been produced. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises
11、 a front cover, an inside front cover, pages i and ii, pages 1 to 21 and a back cover The BSI copyright notice displayed in this document indicates when the document was last issued. w w w . b z f x w . c o m BS 6037-2:2004 BSI 16 September 2004 1 Introduction It is increasingly common for modern co
12、mmercial office buildings to incorporate an atrium and/or a glazed corridor, glazed entrance or roof that requires special provision for continuing maintenance access. Modern shopping malls also often incorporate extensive, high-level glazed roofs which are difficult to access using mobile equipment
13、. The Construction (Design and Management) Regulations 1994 (CDM Regulations) 1 require that all faades and other items that require periodic access are designed and positioned so that they can be accessed safely. To keep these often large and inaccessible areas of glass clean and also to provide sa
14、fe access for the routine maintenance of items such as lights and smoke detectors, these buildings should be provided with some form of permanently installed appliance, which could be in the form of a travelling ladder or gantry, sometimes used in conjunction with a suspended platform. It is essenti
15、al that the requirements for permanently installed access equipment be considered at an early stage in the building design process. The dimensions and capability of any travelling ladder or gantry need to be appropriate for the nature of the task(s) to be performed. The installation can be manually
16、or power operated or a combination of both. It should be noted that working at height can expose workers and other persons in the vicinity to particularly severe risks to their health and safety, in particular the risk of falling from height, falling objects and other serious occupational accidents.
17、 1 Scope This part of BS 6037 gives recommendations for the planning, design, installation, use, examination, maintenance and testing of permanently installed travelling ladders and gantries (TLGs) including equipment installed on a building to facilitate routine maintenance of the building fabric a
18、nd its services. It is intended for those involved in specifying, designing, managing the use of, maintaining and examining such equipment. This standard does not cover TLG systems designed for heavy duty and industrial applications such as underbridge gantries or gantries for industrial processes.
19、Where TLGs are intended to be used in conjunction with suspended access equipment (SAE), this code of practice is supplemented by BS EN 1808:1999 and BS 6037-1:2003. 2 Normative references The following referenced documents are indispensable for the application of this document.

27、or prepared tracks, designed specifically to provide access for operatives to carry out cleaning and maintenance tasks on a building or similar structure and for no other purpose 4 Identifying hazards and taking preventative action 4.1 Design stage Travelling ladders and gantries are required to con
28、form to the Machinery Directive (98/37/EC) 2, which sets machinery design requirements to protect the health and safety of users. At an early stage in the design of the building, a risk assessment should be carried out in order to identify the access requirements and minimize the potential hazards f
29、or the user of a TLG. NOTEIt is a legal requirement under the CDM Regulations 1994 1 that a risk assessment is carried out at this stage. 4.2 Installation, use and maintenance The Management of Health and Safety at Work Regulations 1999 3 require that a risk assessment is carried out before a TLG is
30、 put into use. Site-specific hazards and hazardous situations should be identified and the actions required to eliminate or reduce the associated risks should be incorporated in the risk assessment. A permit-to-work system should be put in place to cover all planned operation, maintenance, testing a
31、nd thorough examination of the TLG. NOTEGuidance on producing permit-to-work systems is given in the HSE publication Permit-to-work systems 1998 4. A list of the more common hazards encountered when using permanently installed TLGs and the actions which should be taken to eliminate or reduce them, i
32、s given in Table 1. Under no circumstances should this list be considered exhaustive. A method statement should be prepared covering the operation of the TLG. The method statement should include the findings of the risk assessment and the measures required to control or eliminate risk. All operators
33、 should be made aware of the findings of the risk assessment and given adequate training and instruction prior to operating or maintaining the TLG (see Clause 19). w w w . b z f x w . c o m BS 6037-2:2004 BSI 16 September 2004 3 Table 1 Hazards encountered when installing, maintaining and using TLGs
34、, and recommended actions HazardAction ExposureSuitable protective clothing should be worn (see 6.4). During severe weather conditions, for example if the work area is icy or during very strong winds, work should not be undertaken and operators should report to the duty holder. Hazardous situation a
35、rising from unauthorized use of the equipment Operators should obtain a permit to work (see 4.2). Hazardous situation arising from other work being carried out in the vicinity Operators should obtain a permit to work and authorization from the duty holder prior to commencing work (see 4.2). Falling
36、or trippingOperators should follow prescribed safe route(s) of access and egress (see 6.2). Where there is inadequate roof edge protection, safety anchors and/or safety lines and safety harnesses should be used. Suitable, marked anchorage points should be provided on the working platform to permit t
37、he attachment of harnesses. SlippingAlgae and other hazardous materials should be removed from all access and egress routes and working areas. Injury to passers by from falling objects Loose objects and tools should be secured with lanyards. Warning notices or barriers should be erected below the wo
38、rkplace (see Clause 20). Persons stranded on the TLG Operators should receive training in the safe use of the TLG and should follow the correct procedures as given in the operating instructions. Operators should be supplied with a means of communication between the TLG and a competent person. Rescue
39、/recovery procedures should be planned in advance. Damage to power cablesPower cables should be of adequate length to allow for movement of the TLG and should be routed such that they cannot become severed or damaged by movement of the TLG. Electric shockOnly competent persons should have access to
40、the electrical circuitry of the TLG. The TLG should be switched off or isolated before any maintenance work is carried out on it (see Clause 12 and Clause 22). The mains power supply should be provided with a residual current device (RCD). Injury resulting from maloperation or malfunction of the TLG
41、 Operators should receive training/instruction in the safe use of the TLG and should follow the correct procedures as given in the operating instructions. All limit switches and safety devices should be operational at all times and checked at appropriate intervals to ensure they are fit for use (see
42、 Clause 12 and Clause 22). Collision of TLGs with scenic lifts or mobile devices installed on the same building or neighbouring buildings Suitable interlocks or controls should be provided and the work planned to remove any danger of the TLG colliding with the scenic lifts or mobile devices. w w w .

A permanent install
44、ation can affect the structure, layout and fenestration of a building and the access requirements should therefore be considered during the preliminary design stage. NOTE 1Significant financial savings and design advantages can result from an early consideration of access requirements. Once the desi
45、gn of a building has been finalized it can be very difficult to make changes to enable installation of TLGs to be carried out (see 7.4). The preliminary design for any travelling ladders and gantries should be based on advice and guidance concerning the various types of system available and should,
46、therefore, be prepared by a competent person. The dimensions and characteristics of the TLG should be appropriate for the nature of the task(s) to be performed. The general planning details should be settled at the earliest possible stage by detailed investigation by and agreement between, the build
47、ing designer and the manufacturer or supplier of the TLG and the results incorporated in the technical file for the building. NOTE 2This agreement will be necessary to enable the TLG to be CE marked (see BS 6307-1:2003, Annex A). The prime responsibility to ensure that access for building maintenanc
48、e is safe lies with the duty holder. Persons involved in the planning and exchange of information should include: a) duty holder; b) equipment manufacturer or supplier; c) architect or designer; d) structural engineer; e) planning supervisor; f) principal contractor; g) local authority; h) client. P
49、ersons involved in the planning and exchange of information can vary from one installation to another and can include persons not mentioned in the above list which should therefore not be assumed to be exhaustive. 5.2 Exchange of information 5.2.1 Information for the manufacturer or supplier The architect or designer of the building should provide information to the manufacturer or supplier of the TLG on such matters as: a) the purpose(s) for which the TLG is to be
