Dust collectors are widely used to remove airborne dust from workspaces. When used for the collection of ULTRA-FINE dust (most hazardous), the risks associated with operating these machines are often overlooked. These risks include: the incorrect use of HEPA filters in machines that are not suited for that purpose; the collected hazardous-dust waste handling and disposal; the post-project cleaning of equipment; and the contaminated filter exchange process. The paper discusses each risk, as well as mitigation steps to manage processes more safely to reduce potential risk.
