5、ver, attention is drawn to the fact that during the development of this amendment A1, the UK voted against its approval. The reason for this disapproval is that The Construction (Health, Safety and Welfare) Regulations 1996 Statutory Instrument 1996 No. 1592 require the main guardrail, or other simi
6、lar means of protection, to be at least 910 mm above the edge from which any person is liable to fall. This standard specifies 700 mm high guardrails, which contravenes these Regulations. Attention is also drawn to the proposed work at height regulations to implement Directive 2001/45/EC, which is l
7、ikely to increase this minimum main guardrail height.

29、97 BSI 7 October 2004 3 0 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 used as a g
30、uide in the preparation of this standard. This standard has been prepared as 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 addition, li
31、fting equipment shall comply as appropriate with EN 292 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 operated and which are des
32、igned 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 s hoists. The stand
33、ard 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. 1.3 This standard is
34、 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); manually or pow
35、er 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 describes methods for
36、 the elimination or reduction of these hazards and for the use of safe working practices. 1.5 This standard does not specify the requirements for dealing with the hazards involved in the manoeuvring, erection or dismantling, fixing or removing of any materials or equipment which are not part of the
37、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 equipment is referred to as lifts or hoists and is dealt with by other st
38、andards. 1.7 This standard does not include mobile elevating work platforms (MEWPs) according to prEN 280, suspended access equipment according to prEN 1808 or lifting tables according to prEN 1570. ?
