Asbestos concern for consumer products containing Libby vermiculite

People who purchased and used company products that contain Libby vermiculite may have been exposed to asbestos fibers from using those products in and around their homes.

At this time, determining the public health implication of commercial or consumer use of company products (such as home insulation or vermiculite gardening products) that contain Libby vermiculite is beyond the scope of this evaluation. However, studies have shown that disturbing or using these products can result in airborne fiber levels higher than occupational safety limits.

Additional information concerning products that contain Libby vermiculite has been developed by EPA, ATSDR and NIOSH.

Contaminated vermiculite insulation in homes and in soil could pose an inhalation hazard if it is disturbed. Exposure to asbestos in vermiculite insulation in an uninhabited attic or behind walls should be negligible.

Exposure to asbestos in soil is less likely if the soil is covered by asphalt, concrete, or vegetation. Asbestos fibers do not break down in the environment, and asbestos in soil, may remain for decades.
