Change in PEVs and annotations for some fifty substances – ROHS, Schedule I
On April 28, 2022, in accordance with Order in Council 644-2022 published in the Gazette officielle du Québec on April 13, 2022, the permissible exposure values (PEV) and the annotations to about fifty chemical substances listed in Schedule I of the Regulation respecting occupational health and safety (ROHS, RLRQ, c. S-2.1, r. 13) have been amended. These regulatory changes have not yet been integrated into the Substance Data Sheets of the Sampling Guide for Air Contaminants in the Workplace. An update is underway and will be available shortly. Consequently, the information contained in the Substance Data Sheets of the substances that have been modified or added to Order in Council 644-2022 is probably inaccurate or incomplete for the substances affected by the changes of April 28, 2022. The substances concerned and the associated regulatory changes may be consulted in Order in Council 644-2022.
For additional information on the sampling and analysis of these substances, please contact the IRSST’s Laboratory Division Customer Service at [email protected].
