1.1 本指南旨在为制定和实施空气监测计划提供标准化方法，以保护废物管理设施的工人。本指南可适用于主动处理、储存或处置现场的常规操作，或在打开和清理补救行动现场时可能遇到的特殊情况。 1.2 用户应理解，不可能预测由于有害空气排放物在废物管理设施中可能出现的所有问题。尽管根据本指南获得的空气污染物测量结果可能表明存在可接受或可容忍的有毒物质水平，但在得出现场所有大气污染物均在控制之下且存在合理的安全工作环境之前，仍必须谨慎和判断。 ====意义和用途====== 5.1 空气监测技术多种多样。本指南旨在描述用于设计空气监测计划以保护废物管理现场工作人员的标准方法。 5.2 当进入补救行动现场开始调查或清理作业时，操作人员可能面临火灾、爆炸和急性或慢性健康危害。必须制定强有力的安全和健康计划，包括现场特定伤害和疾病预防计划（IIPP）和安全和健康计划，以指导工人活动。 有关此类计划的详细信息，请参阅OSHA《危险废物操作和应急响应暂行最终规则》和参考文献 ( 1. , 2. ) . 8. 空气监测是此类计划的一个组成部分。本指南描述了可用于评估空气中潜在危险的设备和采样程序，以获得并维持现场的安全工作环境。 5.3 在现场获得空气质量测量值后，必须决定条件是否受控和安全。该决定将取决于污染物的性质和浓度（毒性、反应性、挥发性等）。 )污染物的空间范围（受影响区域、工人数量等），以及可用和需要的工人保护水平。由于所有这些参数通常都是特定于现场的，因此本指南不包括基于空气质量测量的决策指南。 5.4 本指南不包括含有放射性物质的监测场所，也不包括一般安全方面，如获取应急设备或紧急需要的医疗支持。这些项目应包含在工作场所安全和健康计划中。 5.5 理想情况下，本指南与指南结合使用 D4687 .

1.1 This guide is intended to provide a standardized approach for establishing and carrying out an air monitoring program to protect workers at waste management facilities. This guide may apply to routine operations at an active treatment, storage, or disposal site or the extraordinary conditions that can be encountered in opening and cleaning up a remedial action site. 1.2 The user shall understand that it is impossible to predict all the issues that could arise at a waste management facility due to hazardous airborne emissions. Although air contaminant measurements obtained in accordance with this guide may indicate acceptable or tolerable levels of toxic agents are present, care and judgment must still be exercised before concluding that all atmospheric contaminants at the site are under control and that a reasonable safe work environment exists. ====== Significance And Use ====== 5.1 The techniques of air monitoring are many and varied. This guide is intended to describe standard approaches that are used in designing an air monitoring program to protect waste management site workers. 5.2 When entering a remedial action site to initiate an investigation or a cleanup operation, operating personnel may be faced with fire, explosion, and acute or chronic health hazards. A robust safety and health program, including site-specific injury and illness prevention program (IIPP) and a safety and health plan, must be in place to direct worker activity. Details for such plans can be found in the OSHA Interim Final Rule for Hazardous Waste Operations and Emergency Response and Refs ( 1 , 2 ) . 8 Air monitoring is an integral part of such a program. This guide describes equipment and sampling procedures which can be used to evaluate the airborne hazard potential so as to gain and maintain a safe work environment at the site. 5.3 Upon obtaining air quality measurements at the site, a decision must be made as to whether conditions are under control and safe or not. That decision will depend on the nature and concentrations of the contaminants (toxicity, reactivity, volatility, etc.), the spatial extent (area affected, number of workers, etc.) of the contaminants, and the level of worker protection available and needed. Since all such parameters are typically site specific, this guide does not include air quality measurement based guidance on decision making. 5.4 This guide does not include monitoring sites containing radioactive materials, nor does it cover general safety aspects, such as access to emergency equipment or medical support for emergency needs. These items should be covered in a work place safety and health plan. 5.5 Ideally, this guide is used in combination with Guide D4687 .
