Other Information
Health Risks:
This mineral is known to be a respirable carcinogen, and is a common form of asbestos. Exposure to very dusty air or long-term exposure to low level airborne dusts containing fine fibres of the mineral has been found to cause a high risk of serious lung disease including mesothelioma and lung cancer. Care should be taken working with samples that contain fibrous forms of this mineral, to avoid creating or inhaling dusts. Non-fibrous forms, such as in many amphibolites, are safer to handle, but can still produce potentially carcinogenic respirable fibre when crushed. Appropriate dust masks should be worn if working in areas which have dusts likely to be rich in this mineral. Storage and careful handling of specimens has little or no risk.
