Abstract

It has been identified that the content of mixture substances, such as paint thinner, currently marked on the MSDSs is not consistent. There are an increasing number of problems associated with the regular monitoring of workplace environment, based on MSDS; more and more healthrelated problems are related to the management of harmful chemical substances. Under these circumstances, regarding these harmful substances, there is a compelling need for systematically examining the accuracy of MSDSs, and deeply investigating and evaluating toxic chemicals. From paint thinner Type 2 or higher, 36 types in total of chemical substances were detected. Chemical substances that were commonly found were xylene and trimethylbenzene. Accounting for 81.4%, 57 out of 70 paint thinners out on the market, contained over 1.0% of harmful chemical substances. Out of the seven samples, a small amount of benzene of less than 0.1% was detected. The range of content concentration was from 1.8 74.7 ppm. The results of the analysis show that MSDSs had a 46.5% agreement rate between the detected substances and their content labels, while the warming labels on the products had a agreement rate of 28.3%. In other words, the warning labels had a lower agreement rate than MSDSs. Among the examined paint thinners, 39 products had more than a 50% change in their content of components, accounting for 55.7 %, and 55 paint thinners had over a 10% change rate, representing 71.4%.
