On March 26, 2020, according to Decree 159-2020 published on March 11, 2020 in the Gazette officielle du Québec, the Regulation respecting occupational health and safety (RSST, RLRQ, c. S-2.1, r. 13) is amended in Appendix 1. These regulatory changes have not yet been incorporated into the current Substance Data Sheets of the Sampling Guide for Air Contaminants in the Workplace. An update is currently underway and will be available as soon as possible. Consequently, the information contained in the data sheets of substances modified or added in Decree 159-2020 is probably inaccurate or incomplete.

Analysis:

Acétone

Method: IRSST - 22-2
Sampling device:
Sampling media required:
#IRSSTDescription
2120 Activated charcoal tube 100/50 mg

Parameters:
Flow rate: Max: 0,2 L/min
TWA sampling volume: 3 L
STEL sampling volume: 3 L
Principle: Gas chromatography with flame ionization detection (GC-FID)
Precision: 4,7
Minimum reported value 180 µg
Remarks: The analysis can be done by gas chromatography coupled with mass spectrometry (GC-MS, IRSST method #369); in this case the analytical uncertainty (CVa) is 7.8%.

Acétone (ILD-PA)

Method: IRSST - 39-A
Sampling device:
Sampling media required:
#IRSSTDescription

Parameters:
Flow rate: -
TWA sampling volume: -
STEL sampling volume: -
Remarks: Refer to the user's guide accompanying the instrument.
Principle: Direct reading instrument-Photoacoustic detection (DRI-PAD)
Remarks: Acetone quantification in the field is done with a direct-reading instrument (DRI). The minimum reported value is 1mg/m³ (0.4 ppm). The method in the reference corresponds to DRI calibration.

Acétone

Method: IRSST - 22-2
Sampling device:
Sampling media required:
#IRSSTDescription
2695 3M passive dosimeter 3500

Parameters:
Flow rate: 0,0401 L/min
TWA sampling volume: -
STEL sampling volume: -
Remarks: For the monitors, the flow must be considered as being a sampling rate. According to the data from 3M, the precision (CVsampling) of the sampling rate is 2.2%. Refer to the 3M passive monitor guide on the IRSST's Web site.
Principle: Gas chromatography with flame ionization detection (GC-FID)
Precision: 6,1
Minimum reported value 180 µg
