According to the study, dust explosions are common in factories and mines that handle small particles, such as a wheat flour silo and a coal mine. Even though dust explosions are usually unintentional, the possibility of them being used by terrorists in the future cannot be overlooked. The non-destructive Attenuated Total Reflectance - Fourier Transform Infrared (ATR-FTIR) spectroscopy was used to investigate dust explosives made from various food-based powders. To ensure safety, the research was carried out using a self-design approach that fulfilled the idea of dust explosion pentagon in a large region. Individual ATR-FTIR spectra's spectral properties were observed and subjected to Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA). The PCA evaluation of pre and post-blast samples revealed a variation of dataset coverage of more than 70% and a good correct classification of more than 90% for the LDA tests. The cross validation of pre-blast model with unknown post-blast sample resulted insufficient amount of correct classification (44.4%) while post-blast discrimination model against unknown post-blast sample resulted a good correct classification (96.3%). shafika UTM 68 p.
