Additional Information

For both ordinary and extraordinary situations including hostile acts the TC is concerned with the effects of particulate contaminants on the quality of air supplied to and exhausted from enclosed spaces, and with the sources of particulate contamination pollution within such spaces. The scope of TC 2.4 does not include purely physiological or toxicological aspects of particulate pollution.  Click here for the TC Roadmap.
