Silica Control Tool for the construction industry coming to Ontario Nov. 3

Beginning Nov. 3, workers and employers in Ontario's construction industry will be able to access the Silica Control Tool, its associated data, and outputs. Originally developed by the British Columbia Construction Safety Alliance (BCCSA), the tool has been fully customized to meet Ontario's occupational health and safety standards.

The tool ultimately identifies processes that may lead to silica exposures over the allowable exposure control limit, provides information about how to bring the exposure within the allowable limit, and produces a corresponding Exposure Control Plan (ECP) for the user.
