SM-32-MC (REV. 4-79) Shell Oil Company Shell Chemical Company Interoffice Memorandum APRIL 3, 1984 FROM: TO: SUBJECT: SR. INDUSTRIAL HYGIENIST MAINTENANCE MANAGERS NORTH/SOUTH RESPIRATOR SELECTION FOR ASBESTOS The attached recommendation to discontinue one type of respiratory protection for asbestos exposure was recently distributed to the field for implementation. If Industrial Hygiene can assist in reviewing this change with any Shell field group directly affected, please let me know. The basis of this decision was not that the respirators in prior use were ineffective, rather that dual cartridge respirators and the 9920 mask appear to have a higher level of acceptance by both employees and regulatory agencies.
