The oldest recorded case of a dust explosion occurred in 1785 in a bakery warehouse in Italy, attributed to an explosion caused by airborne flour. Over the past 230 years, dust explosions have not ceased to exist in relation to powders. As Aisin Industry, which provides powder handling equipment, we are offering Stif's explosion protection devices to contribute to achieving safer powder processes and are proposing appropriate measures. Many of you may be familiar with dust explosions, but to raise awareness of their dangers among those who may not have been particularly concerned until now, we have published an article on explosion protection in the technical magazine "Chemical Equipment."
