It supersedes BS EN 1495:1998, which is withdrawn. The start and finish of text introduced or altered by am
2、endment is indicated in the text by tags !“. Tags indicating changes to CEN text carry the number of the CEN amendment. For example, text altered by CEN amendment 1 is indicated by !“. The UK participation in its preparation was entrusted to Technical Committee MHE/12, Lifting platforms. A list of o
3、rganizations represented on this committee can be obtained on request to its secretary. The UK as a member of CEN is obliged to publish EN 1495:1997/A1:2003 as a British Standard. However, attention is drawn to the fact that during the development of A1:2003, the UK voted against its approval. The r
4、eason for this disapproval is that, where The Construction (Health, Safety and Welfare) Regulations 1996 Statutory Instrument 1996 No. 1592 requires the main guardrail, or other similar means of protection, to be at least 910 mm above the edge from which any person is liable to fall, this standard s
5、pecifies 700 mm high guardrails. Attention is also drawn to The Work at Height Regulations 2005 which also sets the minimum main guardrail height at 910mm. The textual error set out below was discovered when the English language version of EN 1495:1997/A1:2003 was adopted as a national standard. It
6、has been reported to DIN in a proposal to amend the text of the European Standard.

26、+A2:2009EN 1495:1997+A2:2009 (E) 4 Introduction This standard is one of a series of standards produced by CEN/TC 98 as part of the CEN/CENELEC programme of work to produce machinery safety standards. EN 414 (Safety of machinery Rules for the drafting and presentation of safety standards) has been us
27、ed as a guide in the preparation of this standard. This standard has been prepared to be a harmonized standard to provide one means of conforming with the essential safety requirements of the Machinery Directive. The extent to which hazards are covered is indicated in the scope of this standard. In
28、addition, lifting equipment shall comply as appropriate with !EN ISO 12100“ for hazards which are not covered by this standard. 1 Scope 1.1 This standard specifies the special safety requirements for Mast Climbing Work Platforms (MCWP) which are temporarily installed and are manually or power operat
29、ed and which are designed to be used by one or more persons from which to carry out work. The vertical moving components (work platform) are also used to move those same persons and their equipment and materials to and from a single boarding point. These restrictions differentiate MCWPs from Builder
30、s hoists. The standard can also be used for permanently installed MCWP. 1.2 This standard is applicable to work platforms elevated by rack and pinion and guided by and moving along their supporting masts, where the masts may or may not require lateral restraint from separate supporting structures. 1
31、.3 This standard is applicable to any combination of the following alternatives: One or more masts; Mast tied or untied; Mast of fixed or variable length; Masts vertical or inclined between 0 and 30 to the vertical; Masts which are standing or hanging; Movable or static base (chassis, or base frame)
32、; Manually or power operated elevation; Towed or self powered ground travel on site, excluding road traffic regulation requirements; Driven using electric, pneumatic or hydraulic motors. 1.4 This standard identifies the hazards arising during the various phases in the life of such equipment and desc
33、ribes methods for the elimination or reduction of these hazards and for the use of safe working practices. BS EN 1495:1997+A2:2009EN 1495:1997+A2:2009 (E) 5 1.5 This standard does not specify the requirements for dealing with the hazards involved in the manoeuvring, erection or dismantling, fixing o
34、r removing of any materials or equipment which are not part of the Mast Climbing Work Platform (MCWP). Neither does it deal with the handling of specific hazardous materials. 1.6 This standard does not specify the requirements for delivering persons and materials to fixed landing levels. Such equipm
35、ent is referred to as lifts or hoists and are dealt with by other standards. 1.7 This standard does not include Mobile Elevating Work Platforms (MEWPs) according to #EN 280$, Suspended access equipment according to #EN 1808$ or Lifting tables according to #EN 1570$. 2 Normative references #The follo
