In some cases, job conditions may dictate more stringent requirements. These could include completely wetting down the area with water when removing old insulation, or completely isolating the' work area tarpaulins, etc. These procedures are to be used in conjunction with Plant Safety Rules, Maintenance Standard Safe Work Procedures for the Area, and Safety Standards, -4- ST054003I HANDBOOK FOR HANDLING ASBESTOS MATERIALS Index Page(s) 1.

The intent i6 to minimize future exposure of employees to asbestos dust in any form through the proper use of safe work procedures. Asbestos is widely used as structural Wall board, insulation, and roofing material. Asbestos fibers are used as a mechanical reinforcing matrix in insulation, roofing paper, certain piping systems, etc. When working with materials which contain asbestos fiber, care must be taken to eliminate as much loose dust as possible. Wetting, isolating the work area, or other suitable procedures to eliminate the dust hazard is absolutely necessary. Should a hazard exist and these procedures are not sufficient, contact the superintendent of the Plant A or B Functional groups. Exceptions to these procedures can be obtained only by the above responsible superintendent. -2 - 6200*1SLOU SAFETY Materials described herein are furnished in blocks (ox lags) shapes, curved segments, pre-formed pipe and fitting covers, flat and corrugated sheets and the asbestos as loose material. When handled, formed, cut, sawed, ot mixed into mortars, a fine dust will be loosed in the air which may be breathed into the human respiratory system. The health of those who breathe asbestos dust may be seriously effected. Results can be similiar to those caused by the more commonly known materials such as silica and coal dust. This phenomena has been observed for many centuries. Current medical discoveries show that handling of asbestos by a confirmed cigarette smoker is especially hazardous in the area of potentially serious lung disorders. It is recommended that those persons handling asbestos not smoke cigarettes in any quantity. The intent of THE DOW CHEMICAL COMPANY is to minimize the exposure of their employees to these hazardous . dusts. In order to accomplish this, substitutes will be used wherever possible. Respiratory protection, dust collectors, blowers, etc., will be mandatory where asbestos containing materials must be handled. The two respirators which have been approved by the Safety Department are: (1) MSA- Dustfoe 77, Dow Stock No, 15-26005, Cartridge No, 15-23775, and (2) Wilson Dust Respirator, Dow Stock No. 15-25460, Cartridge No. 15-23790. -3- 'ST0540030 SAFE WORK PROCEDURE Subject: Fabrication of Asbestos Materials Minimum Safety Equipment Requirements: 1. Side Shield Goggles must be worn. 2. Approved "Nose and Mouth" Dust Respirator must be worn at all times. 3. There shall be a Dust Collecting System on Power Equipment adequate to remove large amounts of dust generated. 4. A Safety Check List is to be filled out prior to the job and properly approved. Turn in to supervisor at completion of job. Special Hazards: 1. Do not breathe asbestos dust. 2. Do not operate equipment if provision cannot be made to eliminate dust in a safe manner. 3. Normal precautions must be taken for working with power equipment. (See specific Safe Work Procedure for Operating Power Driven Tools if in doubt.) 4. When cleaning out the vacuum system of the machines, a respirator must be worn.- Wet down dust prior to handling, if at all possible. Dispose of asbestos dust while in a wet condition. The Yard Department must be notified under these circumstances and disposal by landfill should be accomplished while material is damp. 5. Good housekeeping in the shop area is to be practiced. Asbestos dust must be vacuumed throughout the shop area if and when such conditions exist.

Approved "Nose and Mouth" Dust Respirator must be worn at all times. 3. A Safety Check List is to be filled out prior to the job and properly approved. Turn in to supervisor at completion of job* Special Hazards: 1. Do not breathe asbestos dust. 2* When mixing whole sacks, do not open sacks and dump into open mixing tray*. Moisten asbestos by adding water through a small hole in sack until danger of dust is eliminated. Then the material can be removed if necessary to complete mixing operation to desired consistency. 3. Slipping or falling is a hazard to be considered when working around wet asbestos mud. 4. Back strains from handling containers of mixed mud are also a hazard. A means of handling this mixture may. need to be provided, depending on the circumstances. 5. Keep all personnel not directly involved in the mixing operation away from the area unless they observe minimum safety requirements and have been apprised of the hazards involved. - 7- S70540031* SAFE WORK PROCEDURE Subject: Handling and Storing Asbestos Materials Minimum Safety Equipment Requirements: 1. Side Shield Goggles must be worn. 2. Approved "Nose and Mouth" Dust Respirator must be worn at all times. 3. A Safety Check List is to be filled out prior to the job and properly approved.. Turn in to supervisor at completion of job. Special Hazards: 1. Do not breathe asbestos dust. 2. Handle materials in such a manner as to minimize exposure to dust. 3. Areas used to store asbestos containing materials should be marked "Asbestos Material". Follow Safety Check List procedure when handling. A. Destroy boxes that have contained asbestos materials as soon as boxes are empty. 5. Good housekeeping of shop areas is to be practiced. Clean up all loose dust on floor, machines, shelves, etc., by vacuuming. Wet down and dispose of dust while damp. Notify the Yard Department to dispose by landfill while material is still damp. - 8- ST05400 35 SAFE- WORK PROCEDURE Subject: Sawing and Cutting by Hand Minimum Safety Equipment Requirements: 1.

These Threshold Limit Values are 2% fibers per cubic centimeter* In order to assure compliance with these limits, the Environ mental Health Group will make random samples. When field testing is necessary, call Environmental Health at 238-2121. In order to keep asbestos dust concentration within the proper limits, any dusty conditions connected with the handling of asbestos materials must be kept to an absolute minimum. This must be done as out lined in the previous Safe Work Procedures by wetting down the area, pre-soaking the material, or vacuuming the material as it is cut. Each individual job should be planned with this uppermost in mind. J - 12 - STOS1*0039
