BS EN 349:1993 Safety of machinery. Minimum gaps to avoid crushing of parts of the human body is applicable when adequate safety can be achieved by this method. It aims to enable users (which includes machine designers and standard makers) to avoid hazards that might otherwise arise from crushing zones.
BSI has now published BS EN 349:1993+A1:2008, which amends and replaces BS EN 349:1993, with the 2008 revision adding two new annexes that specify the relationship between the standard and:
- Essential Requirements of the New Approach Directive Machinery 98/37/EC
- Essential Requirements of the New Approach Directive Machinery 2006/42/EC
According to the standard, a number of things have to be considered when specifying minimum gaps, including:
- Accessibility of the crushing zones
- Anthropometric data, taking into account ethnic groups likely to be found in European countries
- Technical and practical aspects
BS EN 349 is applicable to risks from crushing hazards only and is not applicable to other possible hazards, such as impacts, shearing or drawing-in, where additional or other measures need to be taken.
The amended 14-page standard is available from the BSI website for £64 (plus delivery) or £32 to members.
