10、from industry. It has been based on proposals from the joint Powered Access Interest Group of the Construction Plant-hire Association and the International Powered Access Federation.Mobile elevating work platforms (MEWPs) are increasingly being used as temporary working places that provide access to
11、 specific areas at height. For many tasks they can be safer and more convenient to use than other forms of access equipment such as ladders, scaffolding, staging or suspended cradles.Responsibility for the safe operation of MEWPs lies with employers, managers, supervisors, operators and others using
12、 these appliances. This code of practice gives guidance and recommendations to maximize the possibility that appropriate MEWPs are selected for use and positioned, used, maintained and examined safely.The safe operation of MEWPs requires the use of competent operators since inadequately trained pers
13、onnel are unlikely to appreciate the risks involved.It has been assumed in the drafting of this standard that the execution of its provisions will be entrusted to appropriately qualified and competent people, for whose use it has been produced.This Code of Practice provides guidance for hirers, resp
14、onsible bodies and persons using the MEWP to assist them in complying with the Provision and Use of Work Equipment Regulations 1998 (PUWER) 1, the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) 2 and the Work at Height Regulations 2005 3. It also provides valuable guidance for tra
15、ining those involved in MEWP operations. The Health and Safety Executive (HSE) commends the use of this British Standard to those who have duties under the Health and Safety at Work etc. Act 1974 6. This standard was drawn up with the participation of HSE representatives and will be referred to in r
16、elevant publications.As a code of practice, this British Standard takes the form of guidance and recommendations. It should not be quoted as if it were a specification and particular care should be taken to ensure that claims of compliance are not misleading.This publication does not purport to incl
17、ude all the necessary provisions of a contract. Users are responsible for its correct application.Compliance with this British Standard does not of itself confer immunity from legal obligations.Attention is drawn to the following statutory regulations:The Provision and Use of Work Equipment Regulati
18、ons (PUWER) 1;The Lifting Operations and Lifting Equipment Regulations (LOLER) 2;The Work at Height Regulations 3;The Control of Substances Hazardous to Health (COSHH) Regulations 4;The Personal Protective Equipment (PPE) Regulations 5;The Health and Safety at Work etc. Act 1974 6;The Reporting of I

20、i and ii, pages 1 to 47 and a back cover.The BSI copyright notice displayed in this document indicates when the document was last issued.Licensed Copy: Wang Bin, na, Tue Apr 11 01:58:08 BST 2006, Uncontrolled Copy, (c) BSIBS 8460:2005 BSI 30 December 200511 ScopeThis British Standard gives guidance
21、and recommendations for persons responsible for the selection, hiring, positioning, maintenance and thorough examination of mobile elevating work platforms (MEWPs). It also gives guidance and recommendations for the safe use of MEWPs, including the selection and training of operators and other perso
22、nnel, together with guidance to assist in the selection of competent persons.NOTE 1 This British Standard does not give recommendations for delivering persons and materials to fixed landing levels. Equipment intended for this purpose, such as lifts or hoists, are dealt with by other standards includ
23、ing BS EN 12158-1, Builders hoists for goods, BS EN 12159, Builders hoists for goods and passengers and BS EN 81, Safety rules for the construction and installation of lifts.NOTE 2 Mast climbing work platforms (MCWPs) conforming to BS EN 1498, suspended access equipment defined in accordance with BS
24、 EN 1808, lifting tables defined in accordance with BS EN 1570, fire fighting and fire rescue appliances defined in accordance with BS EN 1777, and non-integrated working platforms on forklift trucks are not included within the scope of this British Standard.2 Normative referencesThe following refer
