BS EN ISO 12100:2010 Incorporating corrigendum January 2011 BSI Standards Publication Safety of machinery — General principles for design — Risk assessment and risk reduction (ISO 12100:2010) NO COPYING WITHOUT BSI PERMISSION EXCEPT AS PERMITTED BY COPYRIGHT LAW raising standards worldwide™ BS EN ISO 12100:2010 BRITISH STANDARD National foreword This British Standard is the UK implementation of EN ISO 12100:2010. It supersedes BS EN ISO 12100-1:2003+A1:2009, BS EN ISO 12100-2:2003+A1:2009 and BS EN ISO 14121-1:2007 which are withdrawn. The UK participation in its preparation was entrusted to Technical Committee MCE/3, Safeguarding of machinery. A list of organizations represented on this committee can be obtained on request to its secretary. This standard was formed by combining the latest versions of ISO 12100-1:2003, ISO 12100-2:2003 and ISO 14121-1:2007 without introducing technical changes. Although efforts were made to maintain a balance between the emphases of these individual standards, some compromises have been made. For example, whereas Clause 4 of ISO 12100-1 included requirements and supplementary information for hazard identification, ISO 12100 has adopted the approach of ISO 14121-1 by separating the requirements (see Subclause 5.4) from supplementary information (see informative Annex B). This compromise in no way indicates that the identification of hazards has been given a reduced prominence, as it remains a vital stage in the process of designing safe machinery.
