本标准规定了在工业及非工业环境下防止触及机械危险区的安全距离数值。安全距离适用于保护措施。本标准也给出了有关防止下肢自由触及危险区的安全距离的信息(见4.3)。本标准适用于14岁及以上的人员(14岁人员身高的第5百分位数近似为1400mm)。另外,对于上肢,提供了3岁以上儿童(3岁儿童身高的第5 百分位数近似为900 mm)通过开口触及时所需要的信息。注1:没有考虑防止儿童下肢进入的数据。这些安全距离适用于仅通过距离就能获得足够安全的场合。因为安全距离的依据是尺寸,因此即使满足了本标准的要求,具有某些极限尺寸的人也能够触及危险区。本标准涉及的有关下肢的章节,未考虑在风险评价中不可预见的上肢触及危险。安全距离旨在规定条件下(见4.1.1)防止人员触及危险区。
