May 1 1979 _ ASBESTOS SUBSTITUTES " In 1974 RMC began a program to eliminate the use of asbestos- containing materials which may pose a health hazard to our employees Tests conducted since that time have shown that the machining of marinite board may produce elevated levels of asbestos As a result RMC had discontinued all machining of containing materials Recently however it has been brought to our attention that a the removal and repair of asbestos insulation on pipes boilers etc. may result in an asbestos exposure to the indi- viduals involved in that particular job Although the exposures were below the OSHA standard of 2 fibers they were high enough to require medical surveillance for all affected employees In order to maintain worker exposure as low as possible while performing this operation I am enclosing a copy of a procedure which is to be used while removing and repairing any asbestos- containing insulation - [e, sv ie Cy a Please note that the insulation material should be kept as wet it as possible during the entire operation in order to prevent the release of asbestos fibers into the workplace In addition employees should be issued NIOSH approved respirator for asbestos such as the 8710 while removing and repairing 3 3 the insulation Finally is imperative that an initial monitoring study be conducted to determine every employee's exposure to asbestos while performing this task Please have someone from your plant make an inventory of all areas where containing products may be used This should include all present uses of asbestos as well as removal and repair of insulation already in place After the inventory has been initiate please completed contact the Industrial Hygiene Department to vr the necessary sampling program 2a When replacing insulation every effort should be made to replace = id it with a non containing Mr. A substitutes has been enclosed for be = W.

Rope off the area to prevent anyone from entering it from unknowingly w3 Whenever practical asbestos insulation is to be wetted sufficiently to prevent emission of airborne fibers All scrap asbestos insulation material is to be placed and sealed in labelled bags and disposed of at an approved sanitary landfill ' 5 Whenever possible dry asbestos material shall be vacuumed into impermeable plastic bags Dry sweeping of such mate- rial is prohibited Vacuum cleaners used for asbestos fo clean up should be equipped with a filter to prevent re- introduction of the asbestos fibers into the work environ- ment . 6 The caution signs and rope around the area are to be taken down at the end of the shift unless the work is to be continued on the following shift . PERSONAL PROTECTIVE EQUIPMENT Personnel engaged in removal demolition or clean of . asbestos insulation or removal of coverings from asbestos insulation must wear an approved asbestos respirator 2 Employees shall be trained in the proper use and limitations of each respirator issued for protection against asbestos 3 ( The Company will provide the necessary disposable alls gloves and head and shoe coverings coverings cover- B.001316 % mney L4 After each use contaminated coveralls gloves and head and shoe coverings shall be placed and sealed in labelled plastic bags and disposeodf at an approved sanitary landfill MONITORING MONITORING Skitti Skitti Skitti Skitti Skitti 1 41 . Measurements of airborne asbestos fiber levels shall be conducted by the Corporate Industrial Hygiene Department during the removal or demolition of containing materials or the handling of any other containing . products Merimet Marinite Transite Asbestos paper Thermocouple wire 2 If monitoring shows that the exposure level is in excess of the federal standard monitoring shall be repeated whenever the job is performed 3 If monitoring results made at least five days but not more than three months apart show exposure levels to be below both federal standards eight hour TWA and ceiling value no additional monitoring is required EMPLOYEE NOTIFICATION - Any employee found to be exposed to asbestos fiber in excess of the federal standard must be notified in writing of his results within five working days The employee must also be notified in writing of what efforts are being taken to control such exposure levels : . MEDICAL EXAMINATIONS Personnel assigned to work involving exposures to airborne asbestos in excess of 1 fibers must have had within the past year a comprehensive medical examination The exam.shall ?@ include as a minimum o 1 A chest ray 2 A history of elicit symptomatology of respiratory disease 3 A pulmonary function test to include forced vital capacity FVC and forced expiratory volume at 1 second FEV1 1321 cae 1833 B.001317 a. anwa8J ; .
