•The word "asbestos" comes from the Greek meaning "inextinguishable." •Asbestos is a serious health hazard commonly found What is Asbestos? in our environment today. • Projects on sites where asbestos may be present in soils need to have appropriate risk management measures in place to protect workers and nearby residents. Cover Photo: Water is used to control asbestos at ordered demolitions where asbestos remains in place during demolition activity. Water can act as a slurry, carrying asbestos-bearing sediments and other pollutants offsite to be deposited elsewhere if not contained and managed onsite.

National Industrial Chemicals Notification and Assessment Scheme (Australia). Asbestos is a type of metamorphic mineral group that falls into two classes, serpentine and amphibole. Serpentine has a single chemical in its class, chrysotile ([Mg 3 Si 2 O 5 (OH) 4] n).Amphibole has five chemicals in its class crocidolite, [NaFe 2+ 3 Fe 3+ 2 Si 8 O 22 (OH) 2] n; amosite, [(Mg,Fe 2+) 7 Si 8 O 22 (OH) 2] n; anthophyllite, [(Mg,Fe 2+) 7 Si 8 O 22 (OH).

Chrysotile is a fibrous mineral which does not burn or rot. It is resistant to most chemicals; it is flexible and possesses high tensile strength. This unique combination of properties makes chrysotile an extremely useful material which has been established, for many decades, as a major component of lightweight reinforced cement products.

Chrysotile is considered less harmful to human health than other types of asbestos fibers. Its clearance from the lung is faster and, in comparison to amphibole forms of asbestos, chrysotile asbestos fail to accumulate in the lung tissue due to a mechanism involving fibers fragmentation in short pieces.
