2-20022007-04-12中华人民共和国卫生部发布2007-11-01 实施前言此次修订将GBZ 2-2002工作场所有害因素职业接触限值分为GBZ 2.1工作场所有害因素职业接触限值第1部分：化学有害因素和GBZ 2.2工作场所有害因素职业接触限值第2部分：物理因素。自本部分实施之日起，GBZ 2-2002中相应的内容作废。本部分与GBZ 2-2002相比主要修改如下：a）进一步明确了职业卫生标准所采用的概念及其定义，并增加了以下内容：超限倍数及其应用；总粉尘、呼吸性粉尘和空气动力学直径的定义；化学物质的致癌性参考分类、标识及其应用；致敏性物质的标识及其应用；经皮标识的应用。b）对某些标准值进行了调整：修订了乙腈、乙酸甲酯的接触限值；增订了百草枯、毒死蜱、氯乙酸、钡及其可溶性化合物、萤石混合性粉尘呼尘的接触限值。c）删除了GBZ2-2002中47种粉尘的PC-STEL值和164种化学物质的带*号的PC-STEL值。d）增加参考致癌性标识59项、致敏性标识9项、经皮标识10项。本部分的附录A为规范性附录。本部分由卫生部职业卫生标准专业委员会提出。本部分由中华人民共和国卫生部批准。本部分主要起草单位：中国疾病预防控制中心职业卫生与中毒控制所、复旦大学公共卫生学院、华中科技大学同济公共卫生学院、北京大学公共卫生学院等。本部分主要起草人：苏志、李涛、梁友信、杨磊、王生、张敏、吕伯钦、吴维皑、徐伯洪、刘占元、郑玉新、闫慧芳、陈卫红、谷京宇、杜燮祎、周志俊、夏昭林、何丽华、赵一鸣、黄汉林、缪剑影、刘晓延、张幸、雷玲、朱菊一。本部分所代替标准的历次版本发布情况为：GBZ 2-2002。工作场所有害因素职业接触限值第1部分：化学有害因素1范围本部分规定了工作场所化学有害因素的职业接触限值。本部分适用于工业企业卫生设计及存在或产生化学有害因素的各类工作场所。适用于工作场所卫生状况、劳动条件、劳动者接触化学因素的程度、生产装置泄露、防护措施效果的监测、评价、管理及职业卫生监督检查等。本部分不适用于非职业性接触。2规范性引用文件下列文件中的条款通过本部分的引用而成为本部分的条款。凡是注明日期的引用文件，其随后所有的修改单（不包括勘误的内容）或修订版均不适用本标准，然而，鼓励根据本标准达成协议的各方研究是否可使用这些文件的最新版本。凡是不注明日期的引用文件，其最新版本适用于本部分。GBZ 1 工业企业设计卫生标准GBZ 159工作场所空气中有害物质监测的采样规范GBZ Z/T 160工作场所空气有毒物质测定3术语、定义和缩略语下列术语和定义适用本标准：3.1职业接触限值occupational exposure limits，OELs职业性有害因素的接触限制量值。指劳动者在职业活动过程中长期反复接触，对绝大多数接触者的健康不引起有害作用的容许接触水平。化学有害因素的职业接触限值包括时间加权平均容许浓度、短时间接触容许浓度和最高容许浓度三类。3.1.1时间加权平均容许浓度permissible concentration-time weighted average，PC-TWA以时间为权数规定的8h工作日、40h工作周的平均容许接触浓度。3.1.2短时间接触容许浓度permissible concentration-short term exposure limit，PC-STEL在遵守PC-TWA前提下容许短时间（15min）接触的浓度。3.1.3最高容许浓度maximum allowable concentration，MAC工作地点、在一个工作日内、任何时间有毒化学物质均不应超过的浓度。3.2超限倍数excursion limits对未制定PC-STEL的化学有害因素，在符合8h时间加权平均容许浓度的情况下，任何一次短时间（15min）接触的浓度均不应超过的PC-TWA的倍数值。3.3工作场所workplace劳动者进行职业活动的所有地点。3.4工作地点work site劳动者从事职业活动或进行生产管理而经常或定时停留的岗位作业地点。3.5化学有害因素chemical hazards agents本标准所指化学有害因素除包括化学物质、粉尘外，还包括生物因素。3.6总粉尘total dust可进入整个呼吸道（鼻、咽和喉、胸腔支气管、细支气管和肺泡）的粉尘，简称总尘。技术上系用总粉尘采样器按标准方法在呼吸带测得的所有粉尘。3.7空气动力学直径aerodynamic diameter，dae某颗粒物（任何形状和密度）与相对密度为的球体在静止或层流空气中若沉降速率相等，则球体的直径视作该颗粒物的空气动力学直径。3.8呼吸性粉尘respirable dust按呼吸性粉尘标准测定方法所采集的可进入肺泡的粉尘粒子，其空气动力学直径均在7.07m以下，空气动力学直径5m粉尘粒子的采样效率为50%，简称呼尘。4卫生要求4.1工作场所空气中化学物质容许浓度工作场所空气中化学物质容许浓度见表1。表1工作场所空气中化学物质容许浓度序号中文名英文名化学文摘号(CAS
