It is used in attics as loose fill insulation. Also, it is used in the production of potting soil. Before 1990, the majority of vermiculite was mined in Montana. Asbestos was found in the mine, which led to contamination of vermiculite. Inhaling asbestos fibres can cause lung disease or cancer. The current methods of testing for asbestos contamination in vermiculite may not be accurate. Due to the potential dangers associated with pesticide exposure, and because of inaccuracy of testing methods, it is important that all vermiculite be handled cautiously
Vermiculite can be used in attics as loose insulation and in potting soil.
- Actual testing methods for asbestos contamination of vermiculite may not be accurate.
Long-sleeved shirt and long pants, as well as boots are recommended. You can wear disposable protective clothing to cover your clothes.
Get some vermiculite samples. To get an accurate sample, grab pieces from different parts of the vermiculite. All pieces of vermiculite do not necessarily have asbestos. If you’re testing insulation, take samples of vermiculite which has been thrown to the ground. Also get samples from the high- and low-level areas of the attic. Avoid disturbing the vermiculite insulation. This will prevent asbestos fibres from being released to the atmosphere. The samples should be placed in a baggie.
You can take samples of vermiculite.
- Take pieces of vermiculite in different locations to obtain a better sample.
Your disposable protective clothing should be removed and placed in a bag. Tying the bag together and throwing it out. If the respirator is disposable, throw it away. Place it in a baggie, if it’s not disposable. Keep it out of the reach of children.
The vermiculite samples should be sent to an asbestos testing lab according to their recommendations.
Professionals should take samples of vermiculite. A professional should perform the sample collection of vermiculite insulation to your attic. They have all the equipment required to capture asbestos fibres.
