| Summary: |
This guide, prepared jointly by the IRSST, CSST, and NanoQuebec, proposes a prevention strategy for workplace and research exposure to nanomaterials. It describes the current health risks and safety risks of nanoparticles, including catalytic reactions and fires, and proposes a structured approach to risk management. A case by case risk assessment is preferred, beginning with preliminary information gathering, then information gathering on both health and safety risks, then detailed information gathering, then risk assessment. After both health and safety risks have been assessed, the proposed structure aims to control these risk factors. These include both quantitative assessment of the accident risk involved and where there is insufficient data for quantitative assessment, qualitative assessment under a “control banding” approach. These steps and protective measures to take when a hazard is assessed to exist are described in detail. |
