2016 – All rights reserved ISO 17916:2016(E) Introduction This International Standard has been created in recognition of the particular hazards that are presented by thermal cutting machines This International Standard is a type-C standard as outlined in ISO 12100 When provisions o f a type-C standard are di fferent from those which are stated in type-A or type-B standards, the provisions o f the type-C standard will take precedence over the provisions o f the other standards for machines that have been designed and built in accordance with the provisions of the type-C standard The machinery concerned and the extent to which hazards, hazardous situations, and events are covered are indicated in the Scope of this International Standard Hazards associated with thermal cutting machines are well recognized, but the sources of the hazards are frequently unique to a particular thermal cutting system The number and type(s) o f hazard(s) is (are) directly related to the nature o f the thermal cutting process and the complexity o f the installation The risks associated with these hazards vary with the type o f equipment used, its purpose, and the way in which it is installed, programmed, operated, and maintained This International Standard is not applicable to thermal cutting machines that were manufactured prior to its publication date © ISO 2016 – All rights reserved v
