This Standard establishes values for the minimum gaps to enable machinery designers to avoid hazards from crushing zones. It specifies minimum gaps relative to parts of the human body and is applicable when adequate safety can be achieved by this method.This Standard is applicable to risks from crushing hazards only and is not applicable to other possible hazards (e.g. impact, shearing, drawing-in).For impact, shearing or drawing-in hazards, for example, additional or other measures need to be taken.
