Asbestos Abatement >> How To Encapsulate Asbestos Pipes

Asbestos is a mineral fiber. It can be positively identified only with a special type of microscope. There are several types of asbestos fibers. In the past, asbestos was added to a variety of products to strengthen them and to provide heat insulation and How To Encapsulate Asbestos Pipes fire resistance. How Can Asbestos Affect My Health? 

From  studies of people who were exposed to asbestos in factories and How To Encapsulate Asbestos Pipes shipyards, we know that breathing high levels of asbestos fibers can lead to an increased risk of: lung cancer: -- mesothelioma, a cancer of the lining of the chest and the  abdominal cavity; and -- asbestosis, in which the lungs become scarred with fibrous tissue. 

The risk of lung cancer and mesothelioma increases with the number of fibers inhaled. The risk of  lung cancer from inhaling asbestos fibers is also greater if you smoke. People who get asbestosis have usually been exposed to high levels of asbestos for a long time. The symptoms of these How To Encapsulate Asbestos Pipes diseases do not usually appear until about 20 to 30 years after the first exposure to asbestos. 

Most people exposed to small amounts of asbestos, as we all are in our daily lives, do not develop these health problems. However, if disturbed, asbestos material may release asbestos fibers, which can be inhaled into the lungs. The fibers can remain How To Encapsulate Asbestos Pipes there for a long time, increasing the risk of disease. 

Asbestos material that would crumble easily if handled, or that has been sawed, scraped, or sanded into a powder, is more likely to create a health hazard. Substance: "Asbestos" is the name of a class of magnesium-silicate minerals that occur in How To Encapsulate Asbestos Pipes fibrous form. 

Minerals that are included in this group are chrysotile, crocidolite, amosite, anthophyllite asbestos, tremolite asbestos, and actinolite asbestos. B. Asbestos is and was used in the How To Encapsulate Asbestos Pipes manufacture of heat-resistant clothing, automotive brake and clutch linings.

A variety of building materials including floor tiles, roofing felts, ceiling tiles, asbestos-cement pipe and sheet, and fire-resistant drywall. Asbestos is also present in pipe and boiler How To Encapsulate Asbestos Pipes insulation materials and in sprayed-on materials located on beams, in crawlspaces, and between walls. 

The potential for an asbestos-containing product to release breathable fibers depends largely on its degree of friability. Friable means that the material can be crumbled with hand pressure and is therefore likely to emit fibers. The fibrous fluffy sprayed-on How To Encapsulate Asbestos Pipes materials used for fireproofing, insulation, or sound proofing are considered to be friable.

They readily release airborne fibers if disturbed. Materials such as vinyl-asbestos floor tile or roofing felt are considered non-friable if intact and generally do not emit airborne fibers unless subjected to sanding, sawing and other aggressive operations. Asbestos-cement pipe or sheet can emit airborne fibers if the How To Encapsulate Asbestos Pipes materials are cut or sawed, or if they are broken.

Permissible exposure: Exposure to airborne asbestos fibers may not exceed 0.1 fibers per cubic centimeter of air (0.1 f/cc) averaged over the 8-hour workday, and 1 fiber per cubic centimeter of air (1.0 f/cc) averaged over a 30 minute work period. II. Health Hazard How To Encapsulate Asbestos Pipes Data A. 

Asbestos can cause disabling respiratory disease and various types of cancers if the fibers are inhaled. Inhaling or ingesting fibers from contaminated clothing or skin can also result in these diseases. The symptoms of these diseases generally do not appear for 20 or more years after initial How To Encapsulate Asbestos Pipes exposure. 

Exposure to asbestos has been shown to cause lung cancer, mesothelioma, and cancer of the stomach and colon. Mesothelioma is a rare cancer of the thin membrane lining of the chest and abdomen. How To Encapsulate Asbestos Pipes. Symptoms of mesothelioma include shortness of breath, pain in the walls of the chest, and/or abdominal pain. 

Respirators and Protective Clothing A. Respirators: You are required to wear a respirator when performing How To Encapsulate Asbestos Pipes tasks that result in asbestos exposure that exceeds the permissible exposure limit (PEL) of 0.1 f/cc and when performing certain designated operations. 

Air-purifying respirators equipped with a high-efficiency particulate air (HEPA) filter can be used where airborne asbestos fiber concentrations do not exceed 1.0 f/cc; otherwise, more protective How To Encapsulate Asbestos Pipes respirators such as air-supplied, positive-pressure, full facepiece respirators must be used. 

Disposable respirators or dust masks are not permitted to be used for asbestos work. For effective How To Encapsulate Asbestos Pipes protection, respirators must fit your face and head snugly. Your employer is required to conduct a fit test when you are first assigned a respirator and every 6 months thereafter. Respirators should not be loosened or removed in work situations where their use is required. 

Protective Clothing: You are required to wear protective clothing in work areas where asbestos fiber concentrations exceed the permissible How To Encapsulate Asbestos Pipes exposure limit (PEL) of 0.1 f/cc. Disposal Procedures and Clean-up A. Wastes that are generated by processes where asbestos is present include: 1. Empty asbestos shipping containers. 

Process wastes such as cuttings, trimmings, or reject materials. 3. Housekeeping waste from wet-sweeping or HEPA-vacuuming. 4. Asbestos fireproofing or insulating How To Encapsulate Asbestos Pipesmaterial that is removed from buildings. 5. Asbestos-containing building products removed during building renovation or demolition. 6. Contaminated disposable protective clothing. 

Empty shipping bags can be flattened under exhaust hoods and packed into airtight containers for disposal. Empty shipping drums are difficult to clean and should be sealed. C. Vacuum bags or disposable paper filters should not be cleaned, but should be sprayed with a fine water mist and placed into a labeled How To Encapsulate Asbestos Pipes waste container.  

Process waste and housekeeping waste should be wetted with water or a mixture of water and surfactant prior to packaging in disposable containers. E. Asbestos-containing material that is removed from How To Encapsulate Asbestos Pipes buildings must be disposed of in leak-tight 6-mil plastic bags, plastic-lined cardboard containers, or plastic-lined metal containers. 

These wastes, which are removed while wet, should be sealed in containers before they dry out to minimize the release of asbestos fibers during handling. V. Access to Information A. Each year, your employer is required to inform you of the How To Encapsulate Asbestos Pipes information contained in this standard and appendices for asbestos. 

In addition, your employer must instruct you in How To Encapsulate Asbestos Pipes the proper work practices for handling asbestos-containing materials, and the correct use of protective equipment. Your employer is required to determine whether you are being exposed to asbestos. 

Your employer must treat exposure to thermal system insulation and sprayed-on and troweled-on surfacing material as asbestos exposure, unless results of laboratory analysis show that the How To Encapsulate Asbestos Pipes material does not contain asbestos. You or your representative has the right to observe employee measurements and to record the results obtained. 

Your employer is required to inform you of your exposure, and, if you areexposed above the permissible exposure limit, he or she is required to inform you of the actions that are being taken to reduce your How To Encapsulate Asbestos Pipes exposure to within the permissible limit. C. Your employer is required to keep records of your exposures and medical examinations. 

These exposure records must be kept for at least thirty (30) years. Medical records must be kept for the period of your employment plus thirty (30) years. D. Your employer is required to release your How To Encapsulate Asbestos Pipes exposure and medical records to your physician or designated representative upon your written request.
