According to Decree 280-2024 published on February 28, 2024, in the Gazette officielle du Québec, the amendment to the Appendix 1 of the Regulation respecting occupational health and safety (RSST, RLRQ, c. S-2.1, r. 13) will come into force on March 14, 2024. 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 280-2024 is partially inaccurate or incomplete. Please consult our infoLABO (in French only) for more details. Please contact our client service: [email protected] for further information.

Analysis:

Aluminium (poussière inhalable (exprimé en Al)

Method: IRSST - 418

Sampling device:
Sampling media required:
#IRSSTDescription
948 Cassette and MCE filter, 25 mm, 5 µm, disposable inhalable (DIS)

Parameters:
Flow rate: 2 L/min
TWA sampling volume: 240 L
STEL sampling volume: -
Remarks: Aluminium oxides formed during welding are not dissolved with the actual digestion method. A surface wipe sampling is available. For more information, please contact the IRSST.

Principle: Inductively coupled plasma spectrometry (ICP-MS)
Precision (%): 2,5
Minimum reported value: 10 µg
Remarks: This method allows the analysis of chemical elements present in the sample without distinguishing the different chemical forms. The analytical results are expressed as aluminium, inhalable fraction.

IRSST. "Détermination par ICP-MS des métaux dans la fraction inhalable de l'air des lieux de travail prélevé sur un dispositif de type IOM jetable : DIS (Disposable Inhalable Sampler)". Méthode MA-418. Non publié.
Following the amendment of Appendix 1 of the Quebec Regulation respecting occupational health and safety (RSST, RLRQ, c. S-2.1, r. 13), part of Quebec Occupational Health and Safety Act, which came into effect on March 26, 2020, the TWAEV, STEL and Ceiling values for certain substances are now expressed in ppm. For these substances, the IRSST performed the conversion calculations to express these TWAEV, TWA and Ceiling values in mg/m3, which thus appears in its Sampling Guide for Air Contaminants in the Workplace (Guide d'échantillonnage des contaminants de l'air en milieu de travail ) and the associated Substance Data Sheets. However, it is imperative to refer to the values expressed in the RSST which are legally binding.
