标准范围
This International Standard establishes values for safety distances in both industrial and non-industrialenvironments to prevent machinery hazard zones being reached. The safety distances are appropriate forprotective structures. It also gives information about distances to impede free access by the lower limbs(see 4.3).This International Standard covers people of 14 years and older (the 5th percentile stature of 14 year olds isapproximately 1 400 mm). In addition, for upper limbs only, it provides information for children older than3 years (5th percentile stature of 3 year olds is approximately 900 mm) where reaching through openingsneeds to be addressed.NOTE 1 Data for preventing lower limb access for children is not considered.The distances apply when adequate safety can be achieved by distance alone. Because safety distancesdepend on size, there will be some people of extreme dimensions who will be able to reach hazard zoneseven when the requirements of this International Standard are complied with.NOTE 2 These safety distances will not provide sufficient protection against certain hazards, for example, radiationand emission of substances. For such hazards, additional or other measures need to be taken.The clauses of the International Standard covering lower limbs apply when access by the upper limbs is notforeseeable according to the risk assessment.The safety distances are intended to protect those persons trying to reach hazard zones under the conditionsspecified (see 4.1.1).NOTE 3 This International Standard is not intended to provide measures against reaching a hazard zone by climbingover.
