| Abstract: | Bisphenol A is one of the basic compounds used in a synthesis of polycarbonates and epoxy resins. Its dust can create an explosive mixture with air under specific circumstances. Therefore, the main goal of this research was to determine explosion characteristics and flammability behaviour of this compound. The complete flammability characteristic requires the determination of the basic parameters of Bisphenol A under fire conditions including Heat Release Rate, speed of combustion, ability to ignite and the temperature of the decomposition range. To establish those parameters, a cone calorimeter was used. The explosion characteristics were tested in a 20-L spherical vessel. Minimum Ignition Energy was tested on MINOR II Apparatus which is a modified Hartman's Tube. In order to identify hazardous substances generated during a fire involving Bisphenol A, a simultaneous thermal analysis that combines thermogravimetry and differential scanning calorimetry was used. The substances obtained from the thermal degradation were analyzed by infrared spectroscope with Fourier transformation. Furthermore, the application of a Purser furnace and gas chromatography with mass spectrometry facilitated the identification of gaseous substances formed during the thermal degradation of Bisphenol A samples. |
