have effects on the liver. Occupational exposure limits are (54% chlorine) PEL: 0.5 mg/m3 with <br />a skin notation and (42% chlorine) PEL: 1 mg/m3 with a skin notation. <br />Asbestos <br />• Asbestos is a naturally occurring group of minerals that can only be identified under a <br />microscope. There are several types of these flexible, fire-resistant fibers. <br />• In the past, asbestos was added to a variety of products to strengthen them and provide <br />heat insulation and fire resistance. In most products, asbestos is combined with a binding <br />material so that it is not readily released into the air. <br />• If asbestos fibers should become airborne and is inhaled, it can remain in the lungs for a <br />long period of time, producing the risk for severe health problems that do not appear until <br />many years later. <br />• Asbestos fibers can have serious effects on health if inhaled. There is no known safe <br />exposure level to asbestos. Increased exposure to asbestos will increase the risk of <br />developing an asbestos-related disease. <br />• The amount of time between exposure to asbestos and the first signs of disease can be as <br />much as 30 years. It is known that smokers exposed to asbestos have a much greater <br />chance of developing lung cancer than just from smoking alone. <br />• Asbestos can cause asbestosis, a scarring of the lungs that leads to breathing problems <br />and heart failure. Workers who manufacture or use asbestos products and have high <br />exposures to asbestos are often affected with asbestosis. <br />• Inhalation of asbestos can also cause lung cancer and mesothelioma, a rare cancer of the <br />lining of the chest and abdomen lining. It may be linked to cancer of the stomach, <br />intestines, and rectum, as well. <br />The regulatory occupational exposure limit or permissible exposure limit (PEL) of airborne <br />concentration to asbestos (which includes actinolite, amosite, anthophyllite, chysotile, <br />crocidolite, and tremolite) is 0.1 fibers/cc (cubic centimeter) of air as an eight (8) hour time - <br />weighted average. Work practices that minimize the disturbance of asbestos containing <br />materials should be used whenever possible to control dust emissions. If asbestos containing <br />materials are encountered, and must be disturbed, an initial exposure assessment consistent with <br />the requirements of Title 8, CCR, Section 5208 shall be performed. If asbestos containing <br />materials is encountered it should be immediately reported to the SHSO. The SHSO shall ensure <br />that no employee is exposed to an airborne concentration of asbestos in excess of 0.1 fiber per <br />cubic centimeter (0.1 f/cc) of air as an eight (8) hour time weighted average (TWA). The SHSO <br />shall ensure that no employee is exposed to an airborne concentration of asbestos in excess of 1.0 <br />fiber per cubic centimeter of air (1 f/cc) as averaged over a sampling period of thirty (30) <br />minutes. <br />Santa Fe Road Disposal Site — Health & Safety Plan 16 October 2002 <br />
