Chamoers Wcrks .Mechanical Decartment January 29, 1979 PROCEDURE MDP 60 Sheet 5 of 7 CONTROL OF AS3ESTOS DUST 9. SAMPLING - Continued B. When material sampling is required, the following procedure should be followed: (1) Adhere to all personnel protective and preventive measures indicated in this procedure when obtaining samples. (2) Place material sample to be analyzed in a plastic bag, seal it and deliver it to Room 215 at the Technical Laboratory. Tag the bag with type of material, (e.g. lagging, gasketing, etc.), a listing of possible non-asbestos contaminants, Area,building and equipment number. Allow 3 days for reply. ,' (3) The asbestos identification sheet (Attachment nB") shall be used to record initial sample data. One copy shall accompany sample to the Technical Laboratory Room 215 and other copies may be distributed by Plant mail. C. When the need for air samples is indicated (Section 9-A), contact Environmental Health Division, Technical Laboratory Extension 2540, give a description of the work requested and the location. Follow this with a formal written request (Don't Say It...) and allow 5 to 7 days for a reply. D. Representative samples have indicated that the procedures followed by the Mechanical Department in the handling of asbestos-bearing materials have kept exposure well below the limits set by the Occupational Safety and Health Administra tion (O.S.H.A.). Continued sampling'and air monitoring will be maintained throughout the department. The Environmental Health Division will perform the monitoring, supply the equipment necessary, and provide a written report of the sampling results to the mechanical area supervision who requested the sampling. Each dismantlement job should be monitored for airborne concentrations. All jobs should be considered for monitoring and jobs of 2 hours or greater duration should be monitored for airborne concentrations. The mechanical area responsible shall request monitoring and where employees are exposed to asbestos dust, request personnel monitoring to determine the employee's exposure. Sampling must be taken in a frequency pattern to represent accurately the employees exposure over his work period. q904T^3 DU* tin 0 121264
