Tremolite
Tremolite may occur in fibrous form (an asbestos). It is not used commercially in the United States, but is a common impurity in chrysotile asbestos and vermiculite mined from deposits in Libby, Montana.
ACTS
Asbestos Contractor Tracking System - Asbestos Demolition/ Renovation, and Asbestos Contractor Tracking System in some states is an EPA system
Asbestosis
A progressively restrictive fibrosis of the lung and is recognized as a disabling and fatal occupational
disease.
Actinolite
Actinolite is the intermediate member; when iron is predominant the
mineral is ferro-actinolite and when magnesium is predominant, the mineral is tremolite. The iron
produces a green color that darkens as the iron content increases. Actinolite may occur in fibrous form (an
asbestos). It is not used commercially, but is a common impurity in chrysotile asbestos.
Crocidolite asbestos
One of the six types of asbestos. Crocidolite or "blue asbestos," is found in specialized high temperature applications.
Minimal Risk Level (MRL)
An estimate of daily human exposure to a hazardous substance that is
likely to be without an appreciable risk of adverse noncancer health effects over a specified route and
duration of exposure.
Vermiculite
A chemically inert, lightweight, fire resistant, and odorless magnesium silicate material that
is generally used for its thermal and sound insulation in construction and for its absorbent properties in
horticultural applications. Vermiculite mined from Libby, Montana has been demonstrated to contain various amounts of asbestiform tremolite-like amphibole minerals.
Bulk Sample
A sample of suspected asbestos-containing material that is obtained from a building to be
analyzed microscopically for asbestos content. Bulk sample analysis can be part of a process to assess the
hazard from asbestos in a building.
Pericardial mesothelioma
Pericardial mesothelioma is a highly lethal and fortunately rare cardiac neoplasm
Stage 2 Mesothelioma
Stage 2 mesothelioma has spread to both layers of the pleura on one side of the body only
