AIR MONITORING FOR TOXIC EXPOSURES

 The field of air monitoring is broad from every perspective: the reason for performing the monitoring; the types of air contaminants and the potential hazards they pose; the monitoring techniques and equipment; and the background and skills of the people who carry out the sampling. The purpose of this chapter is to give a general overview of the entire topic in order to make the remaining chapters in the book easier to understand and apply. Remember, almost everything summarized in this chapter is covered in more detail later in the book. Additionally, many of the terms used in air monitoring can have more than one meaning, so this chapter presents the nomenclature that will be used throughout the book. The decision to perform air monitoring for toxic exposures is based on either (a) a regulatory standard that requires monitoring or (b) a hazard evaluation that indicates monitoring is needed to identify or quantify exposures. Hazard evaluations recognize that chemical, physical, and biological agents can cause injury, disease, or death. Potential hazards are evaluated by skilled practitioners based on: • Toxicity of the material—the material’s inherent capacity to cause disease or injury
