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.

AIR MONITORING FOR TOXIC EXPOSURES0d0a 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 28a29 a regulatory  standard
that requires monitoring or 28b29 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
