When the explosion calamity happened, life and property must be paid out with huge economic costs, and the reputation of corporation will deteriorate. For this reason, how to prevent accidents is a significant issue. On this research, we focused on the product of polyester resin and main materials with adipic acid (AA) and p-terephthalic acid (PTA). All of the parameters can be obtained by a variety of measuring equipment. In regards to the physical parameters, particle size analyzer and thermogravimetry can provide the particle size and peak temperature (Tp). Regarding of chemical parameters, minimum ignition energy analyzer and 20-L apparatus are representative instruments for the explosion coefficient. According to the results, particle size have high correlation about the minimum ignition energy tests. In the explosion parameter tests, not only the particle size but also chemical structure should be considered. Regarding the forecast burning velocity, probing its correlation with explosion parameters is a important topic. Therefore, building up a safety as well as complete protection mechanisms is a significant issue.
