Noise exposure limits for Ontario workers in industrial facilities are dropping from 90 dBA for an eight-hour period to a time-weighted average of 85 dBA with a 3 dB exchange rate.  The December 30, 2006 issue of the Ontario Gazette published these changes, which appear as an amendment to section 139 of the Industrial Establishments Regulation (Regulation 851) under the Occupational Health and Safety Act.

These changes to Ontario’s noise exposure limits allow for a more accurate way to measure noise exposure and are intended to help prevent hearing loss. All workplaces in Ontario covered by the Regulations for Industrial Establishments and the Regulations for Offshore Oil and Gas Operators will be covered by the new noise exposure limit, which takes effect July 1, 2007.
