Health & Safety
Chemical & Radiation Hazards

Health-care workers are potentially at risk from workplace exposure to chemical hazards such as hazardous drugs (including antineoplastic agents), gases (including anesthetic gases and helium from magnetic resonance imaging malfunction), cleaning products as well as radiation hazards.

The Ontario Nurses’ Association has dealt with a range of chemical exposures including leaking chemotherapy drugs from faulty equipment, fumes from bleach wipes, and nurses becoming ill from emissions from patients overcome by chemical fumes in their own workplaces. ONA has also assisted members with questions about X-ray protection. Employers have a responsibility to protect you from these hazards in your workplace.

Ministry of Labour

The Ministry of Labour can inspect workplaces or investigate complaints, injuries or accidents with a view to determining compliance with health and safety law.

When inspectors find violations, they can lay charges and prosecute offenders or issue orders. Consult with your ONA bargaining unit leadership and Labour Relations Officer for help, but if danger is imminent, call your local Ministry of Labour office.
