Everything seems fine. Your systems are running smoothly, nothing looks broken or out of the ordinary. But lurking beyond eyesight, things like combustible dusts and condensates could be building up within your system. And when that happens, safety is jeopardized and employees’ lives are endangered. From flash fires to explosions, several deadly but preventable incidents have occurred across multiple industries due to dust accumulation (for a list of examples, check out this article from Nilfisk). Understanding the combination and characteristics of materials moving through your system and the necessary conveying velocities can help mitigate these risks and help you meet NFPA standards and OSHA regulations.
