77536-68-6 Usage
Uses
Used in Construction Industry:
TREMOLITE-ACTINOLITE is used as a construction material for its strength, durability, and heat resistance properties. It is commonly used in the production of asbestos cement, roofing, and insulation materials.
Used in Fireproofing Applications:
Due to its incombustible nature, TREMOLITE-ACTINOLITE is used as a fireproofing agent in various industries, including construction, aerospace, and automotive. It is used to create fire-resistant coatings, gaskets, and seals.
Used in Chemical Filtration:
TREMOLITE-ACTINOLITE is used as a filtration medium in chemical processes due to its fibrous structure and ability to separate particles from liquids or gases.
Used in Chrysotile Production:
Chrysotile, a fibrous form of serpentine, is a widely used type of asbestos. TREMOLITE-ACTINOLITE can be used as a raw material in the production of chrysotile asbestos.
Safety Profile
Confirmed human
carcinogen with experimental tumorigenic
and neoplastigenic data.
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 77536-68-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,3 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77536-68:
(7*7)+(6*7)+(5*5)+(4*3)+(3*6)+(2*6)+(1*8)=166
166 % 10 = 6
So 77536-68-6 is a valid CAS Registry Number.
