Abstract

To help a safer control of toxic chemicals, this study was conducted to investigate the storage stability of acrolein (ACR) and propylene oxide (PO), both of which are highly inflammable and volatile in Tedlar bags for gaseous chemical sampling. Their storage stability was analyzed considering storage temperatures (2 and 25), chemical concentrations (low conc. ppm and high conc. ppm) and storage times (0, 48, 96, and 144 hr). The bags were also divided into two groups and compared against each other for stability: one group contained a single type of chemical and the other included a mixture of chemicals. As a result, the two chemicals were found to have a low storage stability based on chemical reactivity and storage time. While PO showed statistical significance in terms of concentration and mixing type, ACR presented statistical significance in temperature in the bag with a single type of chemical substance.
