BSI has published BS EN 953:1997+A1:2009 Safety of machinery. Guards. General requirements for the design and construction of fixed and movable guards. This standard has been amended primarily to bring it into line with the new Machinery Directive that comes into force on 29 December 2009 [see the Guide to the New Machinery Directive 2006/42/EC].

Accordingly there is an Annex ZA that refers to the old Machinery Directive 98/37/EC and an Annex ZB that refers to the new Machinery Directive 2006/42/EC. In addition, references to standards have been updated throughout BS EN 953, plus numerous definitions have been revised.

One of the most important changes introduced in the amendment is a new requirement for retained fastenings for fixed guards. Clause 7.2, Retained fastenings, states: 'When it is foreseen (eg maintenance) that the fixed guard will be removed then the fastenings shall remain attached to the guard or to the machinery.' This brings the standard into line with the essential health and safety requirements in the new Machinery Directive.

BS EN 953:1997+A1:2009 (ISBN 978 0 580 62239 7) runs to 36 pages of A4 and is available from BSI priced £138 plus postage and packaging, or £69 for Members of BSI.
