本文件确定了工业和非工业领域的安全距离值 防止到达机械危险区的环境。安全距离适当 用于保护结构。它还提供了阻碍下层居民自由出入的距离信息 四肢（见附件B）。 本文件涵盖14岁及以上的人群（14岁的第5百分位身高为 大约1400毫米）。此外，它只为上肢儿童提供信息 3岁以上（第5百分位身高3岁）- 10岁左右的儿童（约900毫米）通过 空缺需要解决。 注1:规定所有人员的安全距离并不实际。因此，给出的值是 旨在覆盖95%的人口。 不考虑防止儿童进入下肢的数据。 当仅通过距离就能充分降低风险时，距离适用。因为安全 距离取决于大小，一些极端尺寸的人仍然能够到达危险区 即使满足本文件的要求。 遵守本文件中的要求将阻止进入危险区。然而 建议本文件的用户，本文件并未为每一个项目提供所需的风险降低 危险（例如与机器排放有关的危险，如电离辐射、热源、噪音、灰尘）。 涉及下肢的条款仅在上肢接触下肢时适用 根据风险评估，危险区是不可预见的。 安全距离旨在保护试图到达地下危险区的人员 规定的条件（见4.1.1）。 注2:本文件无意提供防止攀爬进入危险区的措施 （见ISO 14120:2015，5.18）。交叉引用:ISO 12100:2010ISO/TR 14121-2:2012ISO 7250（所有部分）ISO 13855ISO/TR 20218-2ISO 14738ISO 13732-1ISO 14120ISO 14119购买本文件时可获得的所有现行修订均包含在购买本文件中。

This document establishes values for safety distances in both industrial and non-industrial environments to prevent machinery hazard zones being reached. The safety distances are appropriate for protective structures. It also gives information about distances to impede free access by the lower limbs (see Annex B). This document covers people of 14 years and older (the 5th percentile stature of 14-year-olds is approximately 1 400 mm). In addition, for upper limbs only, it provides information for children older than 3 years (5th percentile stature of 3-year-olds is approximately 900 mm) where reaching through openings needs to be addressed. NOTE 1 It is not practical to specify safety distances for all persons. Therefore, the values presented are intended to cover the 95th percentile of the population. Data for preventing lower limb access for children is not considered. The distances apply when sufficient risk reduction can be achieved by distance alone. Because safety distances depend on size, some people of extreme dimensions will still be able to reach hazard zones even when the requirements of this document are met. Compliance with the requirements in this document will prevent access to the hazard zone. Nevertheless the user of this document is advised that it does not provide the required risk reduction for every hazard (e.g. hazards related to machine emissions such as ionizing radiation, heat sources, noise, dust). The clauses covering lower limbs apply on their own only when access by the upper limbs to the same hazard zone is not foreseeable according to the risk assessment. The safety distances are intended to protect those persons trying to reach hazard zones under the conditions specified (see 4.1.1). NOTE 2 This document is not intended to provide measures against reaching a hazard zone by climbing over (see ISO 14120:2015, 5.18).Cross References:ISO 12100:2010ISO/TR 14121-2:2012ISO 7250 (all parts)ISO 13855ISO/TR 20218-2ISO 14738ISO 13732-1ISO 14120ISO 14119All current amendments available at time of purchase are included with the purchase of this document.
