Usage

Description

Crocidolite asbestos, a type of asbestos, is a slender, fine, and flaxy fiber known for its fire resistance and resistance to most solvents. It is a naturally occurring, hydrated mineral silicate that is incombustible in air and can be separated into filaments. Crocidolite asbestos is characterized by its blue color and is identified as a significant environmental hazard due to its long-term occupational exposure risks, which can result in lung cancer.

Uses

Used in Construction Industry:
Crocidolite asbestos is used as a heat-resistant material in various construction applications, such as cement, furnace bricks, and insulation materials. Its fire-resistant properties make it a valuable component in creating safe and durable structures.
Used in Automotive Industry:
In the automotive industry, crocidolite asbestos is utilized in brake linings due to its heat-resistant and durable nature. This helps to ensure the safety and performance of vehicles by providing effective braking systems.
Used in Manufacturing of Fire-Resistant Products:
Crocidolite asbestos is also employed in the manufacturing of fire-resistant products, such as protective clothing, fire blankets, and other safety equipment. Its ability to withstand high temperatures and resist fire makes it an essential component in these applications.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

These substances undergo chemical reactions only under relatively severe circumstances or in the presence of an effective catalyst that promotes reaction. They are resistant to ignition, although they may become flammable at very high temperatures. They will be resistant to oxidation/reduction, except in the most severe conditions.

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 with experimental carcinogenic, neoplastigenic, and tumorigenic data by inhalation. Human mutation data reported

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.
