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:

Nickel (respirable dust) (as Ni)

Method: IRSST - 362

Sampling protocol

Sampling device: 941 Respirable impactor (PPI) MCE 37 mm, 0,8 µm, preweighed
Parameters:
Flow rate: 2 L/min
TWA sampling volume: 180 L
STEL sampling volume: -
Remarks: Please note that the use of ECM filters in these cassettes induces a greater variation in the gravimetric analysis. A surface wipe sampling is available. For more information, please contact the IRSST.

Principle: Inductively coupled plasma spectrometry (ICP-MS)
Precision (%): 1,9
Minimum reported value: 2 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 nickel, respirable fraction.
