The smoldering phase can produce excessive <br /> emissions due to the fact that it is not a hot burning phase and does not result in complete <br /> combustion. Therefore, air sampling should continue, and data reviewed, during the <br /> smoldering phase as well to ensure that appropriate health and safety decisions can be <br /> made. <br /> Developing an air monitoring plan and/or recommending air sampling equipment <br /> and methods are beyond the scope of this document, however Adolfson et al., (1994) <br /> present a detailed discussion of this topic. <br /> 29 <br />
