Beryllium [7440-41-7], metal and compounds

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.

Analysis:

Béryllium (exprimé en Be)

Method: IRSST - 359

Sampling protocol

Sampling device:
Sampling media required:

#IRSST	Description
913	MCE filter, 37 mm, 0,8µm, preweighed

Parameters:
Flow rate: 1,5 L/min
TWA sampling volume: 180 L
STEL sampling volume: -
Remarks: Refer to the information in InfoLABO 2018-11 regarding limitations related to gravimetric measurement obtained through the use of these cassette. For surface wipe sampling, contact Laboratory Customer Service.

Analytical protocol

Principle: Inductively coupled plasma spectrometry (ICP-MS)
Precision (%): 2,3
Minimum reported value: 0,0005 µg
Remarks: Specific sampling must be carried out for this substance. This method allows the analysis of chemical elements present in the sample without distinguishing the different chemical forms. The analytical results are expressed as total beryllium.
