Abstract

|
The sixty nine chemicals that are closely linked to chemical accident are designated as the substances requiring preparation for accidents and managed for public health under the Toxic Chemicals Control Act. In this study, storage stability of allyl chloride (AC) and carbon disulfide (CD), which are highly inflammable and volatile in tedlar bags, was studied for gaseous chemicals sampling. Storage stability was studied considering storage temperature (2 oC, 25 oC), chemical concentration (low conc. ppm, high conc. ppm) and storage time (0, 48, 96, and 144 hr). Also, the stability of bags containing one type of chemical substance and the bags containing a mixture of chemicals was compared against each other. As a result, two chemicals showed decreasing storage stability based on storage time. Also two chemicals presented statistical significance of concentration and mixing type.
