Abstract

The objective of this study is to develop a standard procedure to measure the airborne concentrations of different size particles within the vicinity of a dropped container where a significant portion of the contained powder is ejected. Tungsten oxide was selected in this study to represent relatively heavy powders. A typical can with the outer dimensions of 0.11 m diameter and 0.12 m tall was used as the container. The can was dropped in two different configurations: 1) without a lid, and 2) with a lid that has a 6.35 mm diameter hole. The tests were carried out in a full-scale stainless steel environmental chamber. By assuming the breathing rate of 1.2 m3/h of a person, the cumulative uptake amount was calculated. The calculated uptake factor during the first 10 minutes was between 10-9 and 2×108 in reference to the amount loaded, or between 10-8 and 6×10 -5 in reference to the amount spilled.
