Dust and crystalline silica measurement
The French Labor Code sets an occupational exposure limit for mixtures of silica dust and other dusts (Articles R.4412-154 and R.4412-155), and the Order of October 26, 2020 classifies respirable crystalline silica dust as carcinogenic.
Our Fuveau laboratory has been measuring respirable dust and analyzing crystalline silica on PVC and foam filters for over a year.
In April 2024, TERA Environnement extended its accreditations to include inhalable dust on foam.
COFRAC-accredited measurements in workplace air :
- Inhalable and respirable dust on foam
- Respirable dust on 37 mm PVC filter
- Crystalline silica on foam and 37 mm PVC filter
Tridymite, Cristobalite and Quartz on foam
