‘Eurofins Enviro-Works is the only lab in western Canada to offer in-house respirable crystalline silica testing AND one of the only labs in North America to offer the low detection limits we provide for our clients.’
• NIOSH 7500 : Silica by XRD
• We are now offering the analysis of Respirable Crystalline silica by XRD using the NIOSH 7500 method. (Please read details below)
DID YOU KNOW?
Over 2.2 million North Americans are exposed to silica at their work site, many of whom work in industrial and construction fields. Crystalline silica dust is often produced in settings such as mining, quarrying, rock crushing, brick laying, demolition, and abrasive blasting.
There are three forms of crystalline silica: quartz, cristobalite, and tridymite. All of which are classified as a “Group 1, carcinogen to humans.”
Exposure to respirable crystalline silica can cause several health problems such as silicosis, lung cancer, chronic obstructive pulmonary disease, and emphysema.
Enviro-works Inc. is the only lab in western Canada to offer in-house respirable crystalline silica testing AND one of the only labs in North America to offer the low detection limits we provide for our clients. Using the NIOSH 7500 method, analyzing samples using X-Ray Diffraction (XRD), we are able to offer a 5ug detection limit for quartz and cristobalite, and a 20ug detection limit for tridymite.
Crystalline silica exposure is regulated by Alberta OHS, by other provincial occupational health and safety legislation across Canada, and by the Occupational Safety and Health Administration (OSHA) in the United States. Please consult with the labour codes in your area to determine your occupational exposure limits and monitoring regulations.
We also offer bulk silica analysis using a modified approach to the NIOSH 7500 method, with detections limits of 1% mass for alpha quartz, and cristobalite and 2.0% mass for tridymite.
