ABSTRACT

Abatement of most hazardous materials which generate particles in dust is similar in some aspects to abatement of asbestos-containing materials. This chapter discusses the particulars of asbestos abatement projects as a means to illustrate the crucial considerations. It describes the relation of settled dust measurement to encapsulation, enclosure, and removal projects. For dust sampling to be useful in a facility, the data from that facility must be compared to some criterion. Dust and air data correlation through simulation is probably not practical for small facilities, especially for landlords with low profit margins. Settled dust data can be useful in abatement design process. Dust sampling and analysis can also determine if the cleaning techniques are successful. Assuming adequate pre-abatement dust data outside the work area, dust sampling can be used to monitor the containment integrity and to determine the seriousness of any known or suspected compromise.
