The inhalation of asbestos fibers can cause serious illnesses, including malignant lung cancer, mesothelioma a formerly rare cancer strongly associated with exposure to amphibole asbestos , and asbestosis a type of pneumoconiosis.

Long exposure to high concentrations of asbestos fibers is more likely to cause health problems, as asbestos exists in the ambient air at low levels, which itself does not cause health problems.

Asbestos became increasingly popular among manufacturers and builders in the late 19th century because of its sound absorption, average tensile strength, and its resistance to heat, electrical and chemical damage.

When asbestos is used for its resistance to fire or heat, the fibers are often mixed with cement or woven into fabric or mats. Asbestos was used in some products for its heat resistance, and in the past was used on electric oven and hotplate wiring for its electrical insulation at elevated temperature, and in buildings for its flame-retardant and insulating properties, tensile strength, flexibility, and resistance to chemicals.

Chrysotile has been used more than any other type and. It is more flexible than amphibole types of asbestos; it can. The most common use is within corrugated asbestos cement roof sheets. It is also found as flat sheets used for ceilings and. Numerous other items have been made containing chrysotile including brake linings, cloth behind fuses for fire protection , pipe insulation, floor tiles, and rope seals for. Amosite, CAS No. It is found most frequently. Crocidolite, CAS No. It is the fibrous form of the amphibole riebeckite.

Notes: chrysotile commonly occurs as soft friable fibers. Asbestiform amphibole may also occur as soft friable fibers but some varieties such as amosite are commonly straighter. All forms of asbestos are fibrillar in that they are composed of fibers with breadths less than 1 micrometer that occur in bundles and have very great widths. Asbestos with particularly fine fibers is also referred to as "amianthus".

Amphiboles such as tremolite have a crystal structure containing strongly bonded ribbonlike silicate anion polymers that extend the width of the crystal. Serpentine chrysotile has. Other regulated asbestos minerals, such as tremolite asbestos, CAS No. Grace and Company. These minerals are thought to be no less harmful than tremolite, amosite, or crocidolite, but since they are not regulated, they are referred to as "asbestiform" rather than asbestos although may still be related to diseases and hazardous.

In , 2. Russia was the largest producer with about The term asbestos is traceable to Roman naturalist Pliny the Elder's manuscript Natural History , and his use of the term asbestinon , meaning. Wealthy Persians, who bought asbestos imported over the Hindu Kush, amazed guests by cleaning the cloth by simply exposing it to fire.

While traveling to China, Marco Polo described observing miraculous garments that were cleaned by being placed in fires. These garments were likely made from asbestos [ c i t a t i o n n e e d e d ]. Some archeologists believe that ancients made shrouds of asbestos, wherein they burned the bodies of their kings, in order to preserve only their ashes, and prevent their being mixed with those of wood or other combustible materials commonly used in funeral pyres.

Although asbestos causes skin to itch upon contact, ancient literature indicates that it was prescribed for diseases of the skin, and particularly for the itch. It is possible that they used the term asbestos for soapstone, because the two terms have often been confused throughout history. Asbestos became more widespread during the industrial revolution; in it was used as insulation in the U.

Development of the first commercial asbestos mine began in in the Appalachian foothills of Quebec. Approximately , people in the United States have died, or will die, from asbestos exposure related to ship building. In the Hampton Roads. There were approximately 4. States during WWII; for every thousand workers about fourteen died of mesothelioma and an unknown number died from asbestosis. Asbestos fibers were once used in automobile brake pads, shoes, and clutch discs.

Since the mids, a majority of brake pads, new or replacement, have been manufactured instead with linings made of ceramic, carbon, metallic and aramid fiber Twaron or Kevlar—the same material used in bulletproof vests. Kent's filtered cigarette used crocidolite asbestos in its "Micronite" filter from to The first documented death related to asbestos was in In the early s researchers began to notice a large number of early deaths and lung problems in asbestos mining towns.

The first diagnosis of asbestosis was made in the UK in By the s, the UK regulated ventilation and. The United States government and asbestos industry have been criticized for not acting quickly enough to inform the public of dangers, and to reduce public exposure. In the late s court documents proved that asbestos industry officials knew of asbestos dangers since the s and had. Artificial Christmas snow, known as flocking, was previously made with asbestos. In Japan, particularly after World War II, asbestos was used in the manufacture of ammonium sulfate for purposes of rice production, sprayed upon the ceilings, iron skeletons, and walls of railroad cars and buildings during the s , and used for energy efficiency reasons as well.

Production of. In Australia, asbestos was widely used in construction and other industries between and From the s there was increasing concern about the dangers of asbestos and its use was phased out. Mining ceased in The use of asbestos was phased out in and banned entirely. The dangers of asbestos are now well known in Australia and there is help and support for sufferers from asbestosis or mesothelioma.

Serpentine minerals have a sheet or layered structure. Chrysotile is the only asbestos mineral in the serpentine group. In the United States, chrysotile has been the most commonly used type of asbestos.

According to the U. Chrysotile is often present in a wide variety of products and materials, including:. HVAC flexible duct connectors.

This application is a continuation-in-part of my copending application Serial No. Heretofore, in preparing thermally insulated structures such, for example, as refrigerators, the members have been prepared from steel sheets, bars, and the like, assembled to form the exterior and interior walls of the refrigerator with hollow spaces therein and thereafter insulating materials, such as glass wool, balsam wool, or the like, have been packed into the hollow spaces to provide the insulation.

The industrial coatings industry is an exciting field to be in with changes and advancements in all types of coatings occurring on a regular basis. Also known as latex paints, acrylics are water-based and most commonly used in residential and commercial applications. Acrylics are hands down the best for painting dry-wall. These coatings have also come a long way with technology and are frequently used in industrial applications as topcoats for Ultra-violet protection in a high-performance coating system or situation. Alkyds can be an efficient low-cost coating option for light to medium steel coating needs.

Asbestos mining existed more than 4, years ago, but large-scale mining began at the end of the 19th century, when manufacturers and builders began using asbestos for its desirable physical properties: [1] sound absorption , average tensile strength , resistance to fire , heat, electricity, and affordability. It was used in such applications as electrical insulation for hotplate wiring and in building insulation. When asbestos is used for its resistance to fire or heat, the fibers are often mixed with cement or woven into fabric or mats. These desirable properties made asbestos very widely used. Asbestos use continued to grow through most of the 20th century until public knowledge acting through courts and legislatures of the health hazards of asbestos dust outlawed asbestos in mainstream construction and fireproofing in most countries. Prolonged inhalation of asbestos fibers can cause serious and fatal illnesses including lung cancer , mesothelioma , and asbestosis a type of pneumoconiosis. Concern in modern times began in the 20th Century and escalated during the s and s.

Veterans of the First Great Meme War of NavBar Donald Trump Achievements :. Asbestos pronounced: or is a term used to refer to six naturally occurring silicate minerals. All are composed of long and thin fibrous crystals, each fiber being composed of many microscopic 'fibrils' that can be released into the atmosphere by abrasion and other processes. Asbestos is an excellent electrical insulator and is highly resistant to heat, so for many years it was used as a building material. However, it is a well known health hazard, and today its use as a building material is banned in many countries. Inhalation of asbestos fibres can lead to various serious lung conditions, including asbestosis and cancer. Archaeological studies have found evidence of asbestos being used as far back as the Stone Age to strengthen ceramic pots, but large-scale mining began at the end of the 19th century when manufacturers and builders began using asbestos for its desirable physical properties. Asbestos was widely used during the 20th century until the s when public recognition of the health hazards of asbestos dust led to its outlawing in mainstream construction and fireproofing in most countries.

Затем, загородив глаза ладонями, чтобы унять льющийся с боков ослепительный свет, он различил тысячи и тысячи слабенько светящихся точек, висящих в пустоте. Они образовывали решетку -- столь же непостижимую для него и лишенную всякого смысла, какими для древний людей были звезды.

Он неотрывно смотрел на этот рисунок в течение нескольких минут и не заметил, чтобы цветные эти огоньки меняли свои места или яркость. Впрочем, подумал Олвин, загляни он в свой собственный мозг, то понял бы не .
