Vermiculite Exposure, Responsiveness Of Vermiculite Vermiculite Bilayer Membrane A Digital Download Scientific Diagram

Asbestos causes cancer and other diseases.

Printable coloring pages for adults online. Risk of exposure to asbestos if you have vermiculite insulation. There is no known safe level of asbestos exposure. Moving the vermiculite will cause fibres to become airborne.

Vermiculite is a hydrous phyllosilicate mineral which undergoes significant expansion when heated. It has been demonstrated as being safe to use and no serious health risks have been found resulting from exposure to vermiculite. Despite the many uses and benefits of vermiculite exposure to the mineral does carry some potential health risks due to its association with asbestos.

The best way to minimize asbestos exposure from vermiculite is to not remove or disturb the insulation. The epa concluded that exposure to asbestos from some vermiculite products poses only a minimal health risk. Large commercial vermiculite mines currently exist in the united states of america.

Nobody should go into the attic. The epa recommended that consumers reduce the low risk associated with the occasional use of vermiculite during gardening activities by limiting the amount of dust produced during vermiculite use. Exfoliation occurs when the mineral is heated sufficiently and commercial furnaces can routinely produce this effect.

Ated with exposure to asbestos contaminated vermiculite the environmental protec tion agency epa conducted a series of tests to evaluate the extent and nature of the risk. Do not use the attic for storage. Asbestos fibers must be airborne to cause a health risk through inhalation so the first step is not to disturb the material which would release more fibers into the air.

Vermiculite mined near libby montana which accounted for more than half the worldwide production of vermiculite from 1925 to 1990 was contaminated with asbestos and asbestos like fibers. The following precautions will prevent releasing asbestos fibres into the air. Vermiculite is a mineral that rapidly expands when heated.

This level represents a health risk if the asbestos is inhaled with exposure to the fibers resulting in serious respiratory diseases. With this in mind its vital that you take the time to perform an asbestos analysis to ensure the vermiculite on your work site is not contaminated with the hazardous substance. Vermiculite forms by the weathering or hydrothermal alteration of biotite or phlogopite.

Expanded vermiculite is used in construction and consumer materials. The results of this investigation indicate that the potential exposure to asbestos from some vermiculite products poses only a minimal health risk to consumers. This study was the first to examine the association between asbestos contaminated vermiculite exposure and the prevalence of respiratory symptoms among individuals no older than 18 years of age while the mine was active and who were continually exposed through lingering contamination in libby.
