Shell Oil Company
Interoffice Memorandum
DECEMBER 3, 1986
FROM:
SR. INDUSTRIAL HYGIENIST, HEALTH & SAFETY, MFG. & TECH.
TO: SEE ATTACHED DISTRIBUTION LIST
SUBJECT: ASBESTOS MONITORING SUMMARY
Attached for your information is an updated (as of 12/1/86) surnnary of asbestos monitoring data that has been collected at Shell's manufacturing locations. As a reminder, initial monitoring for brake repair should have been completed by October 20th. The Shell data available confirms OSHA's observation that such exposures are controllable by specific workpractices.
Major asbestos removal continues to be the central exposure issue. Since July the percentage of samples which exceed 0.1 f/cc has apparently de- creased from 34% to 272 and for 0.2 f/cc, 202 to 152. However, the number of measurements involved remains relatively small.
As previously requested, additional data collected but not represented should be identified. Additional data or corrections to the attached may be made by "writing in the changes" or mailing in applicable worksheets to me (1190 One Shell Plaza).
A few interesting observations regarding the attached:
During major removal work, where asbestos exposure above 0.2 f/cc was measured, 802 of the time 0.2 f/cc was also exceeded when cal culated on an eight-hour TWA basis.
The median overstandard TWA (of 18 measurements) is 0.33 f/cc.
Only two overstandard measurements have been reported during 1586, both were associated with the removal of asbestos from an exchanger while using the wet method. Plastic sheeting had been used to iso late the job which lasted only one shift.
More information to follow.
