-273 12-511 INTEROFFICE CORRESPONDENCE J. G. Keller Medical Room 1425 March 10, 1975 received PERSONAL PROTECTIVE MEASURES TO EE FOLLOWED DURING ASBESTOS REMOVAL OPERATIONS This will confirm our conversation of March 7 regarding the captioned. We agree that generally the guidelines as written in the attachment to your letter of January 2, 1975, copies to P. C. Ingalls, P. C. Krist, E. L. Waggoner and J. Walker are adequate for their intended use. Our version of the guide is attached for your review. Quite obviously the material is not all inclusive nor can it be if it is to be used worldwide by Mobil Oil Corporation. Detail ed instructions as to the use of a NIOSH-approved respirator etc. would need to be written in by NAD if they feel it is necessary. Also attached for your review and comments is a copy of Procedure Guide, No. 50393-0001, which we propose to issue to the International Division. HHB/mlp Attachments H. H. Beams 002210 1838T6 Personnel Protective Measures to "be Followed During Asbestos Removal Operations 1. All asbestos containing insulation must be thoroughly wetted with water before removal. Wetting can be accomplished by any practical means such as hose lines or water spray from self-contained apparatus. Wet steam is another possible means of saturation of asbestos if feasible and conducted safely. Five minutes of water application for 25 square feet of asbestos surface insulation area should suffice. When asbestos is being removed, a suitable means of contain ment must be used to catch chunks of asbestos to prevent dispersion of asbestos fibers. 2. Employees involved in the removal operation must be equipped with a single-use, disposable respirator as approved by appropriate local government authority. If no single-use respirator is approved and it is necessary to use one approved for multiple use, it should be discarded after use. Employees also must wear gloves, coveralls and shoe covers. Gloves, coveralls and shoe covers, wherever possible, should be of the single-use, disposable type. Employees must not continue to wear this protective clothing if they leave the job site for another activity and specifically when eating. If non-disposable protective clothing is used, the collection and laundering procedures as outlined by the Medical Director's office of Mobil Oil Corporation must be followed. 3. Asbestos-insulation waste, debris and used disposable clothing must immediately be packed in impervious bags and affixed with cautionary tags. The tag shall state: * CAUTION Contains Asbestos Fibers Avoid Creating Dust Breathing Asbestos Dust May Cause Serious Bodily Harm ** 002231 183877 EMPLOYEE RELATIONS PROCEDURE GUIDE Guide No. 50393-0001 Medical Supervision of Asbestos Workers Mobil Oil Corporation International Division PURPOSE All New York departments and subsidiaries To set forth suggested guidelines for use by subsidiaries in establishing procedures for the eventual elimination of employee exposure to asbestos and asbestos products in the working environment. NOTE: Mobil Oil Corporation and its subsidiaries operating in the United States, its territories, and possessions are required to adopt guidelines which conform to the WilliamSteiger Occupational Safety and Health Act of 1970. At the time this guide was issued the only Mobil International Division affiliates affected by the U.S. Occupational Safety and Health Act were Mobil Oil Caribe, Inc., San Juan Garage, Mobil Oil Micronesia, Inc., Mobil Petroleum Company, Guam, and Mobil Technical Services, Inc., Dallas, Texas. These affiliates should be guided by Management Guide 03-1308 Medical Supervision of Asbestos Workers.

JT'D EMPLOYER-CORPORATION MEDICAL DIRECTOR The March 1973 issue of Mobil Engineering Guide EGE 3U-3-10 1973 contains a list of approved insulating materials and specifies approved methods for installing them. No asbestos or asbestos-based materials are approved for installation or re-installation in any class of service for any purpose. The only remaining source of exposure is asbestos insulation already in place. If it is removed for any reason, it should be replaced by an approved type, and it is suggested that subsidiaries establish responsibilities and procedures aimed at protecting the health of employees who may be involved in removing such old insulation. The guidelines set forth below are intended for use in those areas where legislation regulating exposure to asbestos and asbestos products is either lacking or establishes less stringent standards than the standards set forth herein. Wherever the competent government authority has promulgated more stringent standards, they obviously supersede the standards suggested in these guidelines. The employer-corporation Medical Director should: . Provide for preplacement, periodic and termination physical examinations for all employees subject to significant exposure to asbestos dust. . Determine who qualifies for periodic examinations at employer-corporation expense. . Retain medical records for as long as required by local regulations. 002213 183879 Employer-Corporation Industrial Hygienist Local Plant Management The employer-corporation Industrial Hygienist should: . Conduct industrial hygiene surveys of all operations where asbestos is .used, and at a minimum of six months intervals determine employees' exposure to asbestos dust. . Report findings, with recommendations, to the Plant Manager. . In those cases where the affiliate has no qualified industrial hygienist on'its staff, assistance should be requested through the Division or corporate Medical Director's Office with copy of request to Division Safety Office. The employer-corporation Local Plant Management should: . Provide that only appropriate local government office approved respiratory protection devices are used by employees exposed to asbestos dust. . Arrange for the proper inspection, cleaning, repair and storage of respirators as set up in ANSI Standard Z88.2-I96 . Notify asbestos workers to report for preplacement, periodic and termination physical examinations. . Provide and require use of washing facilities and two separate lockers for clothing. . Provide and require use of special protective clothing and change rooms for personnel whose exposure to asbestos is in excess of the ceiling values. See Appendix 4. . Inform the employer-corporation Medicdl -Director of any contemplated change in the handling and use of asbestos. . Maintain for a period of three years records of personal and environmental monitoring from data developed during industrial hygiene surveys. 183880 00221''* Management (cont'd.) . Establish a training and promotional program on the use of personal protective equipment. DEFINITIONS Asbestos Asbestos includes chrysotile, amosite, crocidolite, tremolite, anthophyllite, and actinolite. Asbestos Fibers Permissible Exposure Asbestos fibers are fibers longer than 5 micrometers. The eight-hour time-weighted average airborne concentra tions of asbestos fibers to which any employee may be exposed shall not. exceed two fibers, longer than 5 micrometers, per cubic centimeter of air. No employee shall be exposed at any time to airborne concentrations of asbestos fibers in excess of ten fibers, longer than five micrometers, per cubic centimeter of air. FORMS One way to keep the airborne concentrations below the above levels is to keep old insulation being removed or scrap'insulation wet when it is being handled. See Appendix k. Health Examination History Medical Evaluation These should be whatever forms are used by the affiliate. The English versions of the forms are numbered CO-993 and CO-1091 respectively.
