This PAS will be reviewed at intervals not exceeding two years, and any amendments arising from the re

9、view will be published as an amended PAS and publicized in Update Standards. This PAS is not to be regarded as a British Standard.

11、introduced or altered by Corrigendum No. 1 is indicated in the text by tags . Minor editorial corrections are not tagged. It is intended that this PAS should provide the basis for product conformity certification schemes to provide assurance that collective fall arrest soft landing systems placed on

12、 the market have been independently tested and confirmed as being in accordance with the requirements of this PAS. Users of this PAS are therefore advised to consider the desirability of third-party certification of products in conformance with this PAS. Use of this document It has been assumed in t

13、he preparation of this PAS that the execution of its provisions will be entrusted to a competent person or persons for whose use it has been produced. This specification is not intended to restrict new developments in design and materials and manufacturers of collective fall arrest soft landing syst

14、ems may seek innovative provision of such systems provided their performance is in accordance with the requirements of this PAS.PAS 59:2014 iv The British Standards Institution 2015Presentational conventions The provisions of this PAS are presented in roman (i.e. upright) type. Its requirements are

15、expressed in sentences in which the principal auxiliary verb is “shall”. Its recommendations are expressed in sentences in which the principal auxiliary verb is “should”. Commentary, explanation and general informative material is presented in italic type, and does not constitute a normative element

16、. Contractual and legal considerations This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a PAS cannot confer immunity from legal obligations. Particular attention is drawn to the following speci

17、fic regulations: The Work at Heights Regulations 2005 1; The Construction (Design and Management) Regulations 2007 2; The Management of Health and Safety at Work Regulations 1999 3; The Provision and Use of Work Equipment Regulations 1998 4. The British Standards Institution 2015 1 PAS 59:2014 Intro

18、duction Regulations concerning the use of work equipment at height (see Foreword), require employers to take suitable and sufficient measures to prevent any person falling and where fall prevention is impractical to take action to ensure that the height and consequences of a fall are minimised. Coll

19、ective fall arrest soft landing systems should be considered in this context by virtue of their ability to reduce the free fall height and provide a suitable landing surface. In all cases, employers are required to ensure that work at height, including emergencies and rescue, is subject to a risk as

20、sessment, properly planned by a competent person, appropriately supervised and carried out in a safe manner.1 Scope This PAS specifies requirements for a collective fall arrest soft landing system intended for installation on a continuous, firm, level surface in order to restrict the deceleration of

21、 a person falling onto it to a maximum of 14 g, from a free fall height not more than the maximum free fall height for which the system has been tested. This PAS includes performance requirements and related test methods, requirements for conformity marking and for the provision of installation and

22、usage instructions. This PAS is not applicable to air/gas filled systems that are designed to be inflated/deflated on site or to those that have individual cell volume greater than 0.5% of the volume of the module in which they are inserted. This PAS is not applicable to fall arrest systems that are

23、 suspended. This PAS is not applicable to personal protective equipment against falls from a height. This PAS does not provide for the containment of falling debris.2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable

24、for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendment) applies. BS 5852, Methods of test for assessment of the ignitability of upholstered seating by smouldering and flaming ignition s

26、, General requirements for the competence of testing and calibration laboratories3 Terms and definitions For the purposes of this PAS, the following terms and definitions apply.3.1 boundary walls rigid barriers defining the boundary of a protected area that prevent the modules of a constrained fall

27、arrest system from moving from their designated locationPAS 59:2014 2 The British Standards Institution 20153.2 collective fall arrest soft landing system one or more fall arrest soft landing modules which when installed in accordance with the manufacturers or suppliers instructions, provide an area

28、 of protection capable of dissipating the kinetic energy of one or more persons falling from not more than a specified height onto any part of its surface NOTE The Health and Safety Executive describes “collective protection” as equipment which can protect more than one person and that once properly

29、 installed or erected does not require any action by them to make sure it will work.3.3 competent person for inspection person knowledgeable in the current inspection requirements, recommendations and instructions issued by the manufacturer or supplier in respect of the collective fall arrest soft l

30、anding system under inspection Adapted from BS EN 365:2004 NOTE 1 This person should be capable of identifying and assessing the significance of defects and should have the responsibility to initiate the corrective action to be taken and should have the necessary skills and resources to do so. NOTE

31、2 A competent person may need to be trained by the manufacturer or supplier or an authorised representative on specific equipment, e.g. due to its complexity or innovation, or where safety critical knowledge is needed in the dismantling, reassembly, or assessment of the equipment, and may need to ha

32、ve that training updated periodically due to modifications and upgrades.3.4 constrained collective fall arrest soft landing system one or more fall arrest soft landing modules with or without a means of Inter-connection, that to any extent rely on boundary walls to maintain their location in a conti

39、 extend to boundary walls at the periphery of the protected area. NOTE Where the collective fall arrest soft landing system is to be used to provide protection in a constrained situation, the boundary walls may be presumed to provide positional retention provided the installed modules extend to the

40、boundary walls on all sides.4.1.2 Systems for general use For all use situations other than “constrained use”, the modules of the collective fall arrest soft landing system shall be: free from sharp edges and projections likely to cause injury during use; provided with a means of connection to adjac

42、t a free fall height not more than the maximum free fall height for which the system has been tested, is being undertaken under conditions of intended use; and supplied with installation instructions that stipulate that a risk assessment be undertaken to determine the appropriate protected area for

43、the particular situation of use and whether use of the means of restraint is required. NOTE Where a means of attachment to structures is provided it should be of sufficient strength and stability to ensure the positional retention of modules under impact by a person falling onto them under condition
