O. Reg. 148/12, s. 3; O. Reg. 288/17, s. 1. Schedule 1 PART I   AIRBORNE MEASUREMENT AND CALCULATION OF EXPOSURE 1. Airborne concentrations of a designated substance are expressed as, (a) parts of the agent per million parts of air by volume (ppm); (b) milligrams of the agent per cubic metre of air (mg/m3); or (c) fibres per cubic centimetre of air (f/cc). 2. In determining exposure to airborne concentrations of the designated substance, no regard shall be had to the wearing or use of respirators. 3. Air sampling of the airborne concentrations of the designated substance is not required for the full period of a work day or a work week if the air sampling is representative of airborne concentrations of the substance likely to be present during the full period. 4. The average concentrations of a designated substance to which a worker is exposed shall be determined from analysis of air samples taken as being representative of the exposure of the worker to the designated substance during work operations. 5. Subject to section 6 of this Schedule, the time-weighted average exposure to an airborne designated substance in a work day or work week shall be calculated as follows: 1. The cumulative daily or weekly exposure shall be calculated using the following formula: C1T1 + C2T2 + ... + CnTn where, C1  is the concentration found in an air sample, and T1  is the total time in hours to which the worker is taken to be exposed to concentration C1 in a work day or a work week. 2. The time-weighted average exposure shall be calculated by dividing the cumulative daily exposure by eight and the cumulative weekly exposure by 40 respectively. 6. A determination of time-weighted average exposure for extended work shifts may be calculated using the methodology set out in the Guide for the Adjustment of Permissible Exposure Values for Unusual Work Schedules (March 2015), published by Quebec’s Institut de recherche Robert-Sauvé en santé et en sécurité du travail (IRSST), using the applicable TWA set out in Table 1 of this Regulation. 7. Short-term exposures to the designated substance in any 15-minute period are determined from a single sample or from a time-weighted average of sequential samples taken during that period. O.
