Description
Chrysotile (Mg3H2(SiO4)2.H2O), also known as white asbestos, is a naturally occurring, hydrated mineral silicate that is incombustible in air and can be separated into fine, flaxy fibers. It is characterized by its white or greenish color and is resistant to fire and most solvents. However, long-term exposure to its dust can result in lung cancer, making it a hazardous material to the environment and human health.
Uses
Used in Construction Industry:
Chrysotile (Mg3H2(SiO4)2.H2O) is used as a heat-resistant material for its fire-resistant properties, making it suitable for applications such as cement, furnace bricks, and insulation materials. Its ability to withstand high temperatures without catching fire makes it a valuable component in construction materials that require fire resistance.
Used in Automotive Industry:
In the automotive industry, Chrysotile (Mg3H2(SiO4)2.H2O) is used as a component in brake linings due to its heat-resistant and durable properties. The material's ability to withstand high temperatures and friction makes it an essential part of brake systems, enhancing the performance and safety of vehicles.
Air & Water Reactions
Insoluble in water.
Health Hazard
Inhalation of material may be harmful. Contact may cause burns to skin and eyes. Inhalation of Asbestos dust may have a damaging effect on the lungs. Fire may produce irritating, corrosive and/or toxic gases. Some liquids produce vapors that may cause dizziness or suffocation. Runoff from fire control may cause pollution.
Fire Hazard
Some may burn but none ignite readily. Containers may explode when heated. Some may be transported hot.
Safety Profile
Confirmed human
carcinogen producing tumors of the lung.
Human mutation data reported. Poison by
intraperitoneal route. Human systemic effects by inhalation: lung fibrosis,
dyspnea, and cough.
Potential Exposure
Most asbestos is used in the construction
industry. Much of it is firmly bonded, i.e., the asbestos
is “locked in” in such products as floor tiles, asbestos
cements, and roofing felts, and shingles; while the remaining
8% is friable or in powder forms present in insulation
materials, asbestos cement powders, and acoustical products.
As expected, these latter materials generate more airborne
fibers than the firmly bonded products. The asbestos
used in nonconstruction industries is utilized in such products
as textiles; friction material including brake linings
and clutch facings; paper, paints, plastics, roof coatings;
floor tiles, and miscellaneous other products. Significant
quantities of asbestos fibers appear in rivers and streams
draining from areas where asbestos-rock outcroppings are
found. Some of these outcroppings are being mined.
Asbestos fibers have been found in a number of drinking
water supplies, but the health implications of ingesting
asbestos are not fully documented. Emissions of asbestos
fibers into water and air are known to result from mining
and processing of some minerals. Exposure to asbestos
fibers may occur throughout urban environments perhaps
resulting from asbestos from brake linings and the flaking
of sprayed asbestos insulation material. In recent years,
much effort has been put into removal of asbestos insulation,
particularly from schools and other public buildings
where worn or exposed asbestos causes public exposure.
Incompatibilities: None
Shipping
UN2212 Blue asbestos (Crocidolite) or Brown
asbestos (amosite, mysorite), Hazard class: 9; Labels:
9-Miscellaneous hazardous material. UN2590 White asbestos
(chrysotile, actinolite, anthophyllite, tremolite), Hazard
class: 9; Labels: 9-Miscellaneous hazardous material.
Waste Disposal
Asbestos may be recovered
from waste asbestos slurries as an alternative to disposal.
Landfilling is an option for disposal if carefully
controlled.
Check Digit Verification of cas no
The CAS Registry Mumber 12001-29-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,0 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 12001-29:
(7*1)+(6*2)+(5*0)+(4*0)+(3*1)+(2*2)+(1*9)=35
35 % 10 = 5
So 12001-29-5 is a valid CAS Registry Number.
