On March 9, 2020, the Canadian Center for Occupational Health and Safety (CCOHS) posted a podcast entitled “The Hazards of Nanomaterials and How to Control Exposure.”  CCOHS states that nanomaterials have many useful properties, but the same properties that make them desirable in manufacturing present unique potential safety hazards when workers are exposed to them.  In this episode, Todd Irick from the Occupational Health Clinics for Ontario Workers’ Nanotechnology and Health Network explains why nanotechnology is a health and safety concern in the workplace and how exposure to nanomaterials can be controlled.
