Open cassette sampl<strong>in</strong>g. A flow rate not exceed<strong>in</strong>g 2.5 L/m<strong>in</strong> is recommended<br />
<strong>for</strong> determ<strong>in</strong><strong>in</strong>g an average concentration. Supply at least 2 blanks per series of<br />
samples or 10% of sample total, whichever is highest. Send <strong>the</strong> samples <strong>in</strong> a<br />
cardboard box supplied by <strong>the</strong> IRSST (#3010). In relatively uncontam<strong>in</strong>ated<br />
atmospheres, where <strong>the</strong> fibre concentration is much lower than 0.1 fibres/mL, use<br />
larger sampl<strong>in</strong>g volumes (3000 to 10000L) <strong>in</strong> order to obta<strong>in</strong> quantifiable<br />
densities.<br />
The method applies to <strong>the</strong> count<strong>in</strong>g of all fibres whose refractive <strong>in</strong>dex is<br />
compatible with <strong>the</strong> mount<strong>in</strong>g solution.<br />
The m<strong>in</strong>imum reported value is 25 fibres/mm².<br />
Characterization of <strong>the</strong> fibres <strong>in</strong> bulk samples or <strong>in</strong> deposited dusts is done<br />
us<strong>in</strong>g method 244-2. An analysis us<strong>in</strong>g a transmission electron microscopy (TEM)<br />
method may be required <strong>for</strong> some materials conta<strong>in</strong><strong>in</strong>g f<strong>in</strong>e asbestos fibres, <strong>for</strong><br />
example floor tiles.<br />
