SHRINK-FILMED SUPERVISBESTOS ` he -^ n izer Jbe f lrst ?L shrink-filmed Supervisbestos was examined in the Davis Mud Comift^ ^rehouse in Woodward, OK. A dust count was made while around 100 bags were In i daJ"t0 3 r^UCu-a!!d 0,60 unloaded back int0 the warehouse to simulate delivery on location. The highest asbestos count obtained was 0.6'fiber/cc This is a ^ ceiling value. ' d Visual observation of the bags indicates they were in excellent condition The film was generally quite tight around the bag with only small amounts of asbestos between the film and the bag. There was occasionally a small hole in the film ' The thrown]d ^ asbestos or appear t0 9ive o ff significant dust when handled`or 4.uThx-.man who. unloaded the rail car reported that there was no visible asbestos th"eJrebewfe1rear drozdenthoeyr ftwod b"0agtsevthenathwaveeret0nostwseheprinoku-tfilmedcabru. t wHeeraelslooonseoltyedent cKlosed in a plastic overwrap bag. Examination showed that these had considerably more I!e a ? eSt0V nslde the bag and were somewhat difficult to handle. It is assumed that this was done to complete a load when the shrink film machine was out of order This is certainly a reasonable solution but should be avoided wherever practical. * Dust counts were also made at two rigs where the shrink-filmed Supervisbestos I f a S n ^ c o u n t e mUd' ^ h<sh8St aSbe5t S C0Unt fUnd ^ TMs MAGOBAR OIL-BASED MUD In response to Mr. Campbell's questions the current status was presented as: 1.
