WHAT IS ASBESTOS? ASBESTOS IS A CRYSTALLINE FORK OF IMPURE MAGNESIUM SILICATE MINERALS IN THE FORM OF FIBERS. IT CAN BE ANY COLOR. MATERIALS MAY CONTAIN A WHOLE RANGE OF ASBESTOS CONCENTRATIONS ----- UP TO 100%. 2. WHERE CAN ASBESTOS BE FOUND? ASBESTOS HAS BEEN USED IN INSULATING MATERIALS, AS A BINDER MATERIAL, GASKETS, ROOFING, FLOOR TILES, WAIL BOARD (TRANSITS), PIPING, CEILING TILES, BRAKE LININGS, AND MANY OTHER APPLICATIONS. THE MOST COMMON DIVISION APPLICATIONS INCLUDE INSULATION AND TRANSITS SIDING. 3. HOW IS ASBESTOS IDENTIFIED? SINCE ACCURATE VISUAL IDENTIFICATION OF ASBESTOS IN MATERIALS IS NOT DONE EASILY, IT IS VERY IMPORTANT THAT IDENTIFICATION BE DONE PRIOR TO HANDLING POTENTIAL ASBESTOS-CONTAINING MATERIALS. CHEMICAL OR PHYSICAL TESTS THROUGH MICHIGAN DIVISION INDUSTRIAL HYGIENE SERVICES OR MAS&TL ANALYTICAL LABORATORIES (1602 BUILDING) ARE REQUIRED FOR ASSURANCE OF ACCURATE DETERMINATION. 4. HOW IS ASBESTOS TO BE HANDLED? THE PROCEDURES FOR THE SAFE REMOVAL AND/OR DISPOSAL OF ASBESTOS-CONTAINING MATERIALS ARE FOUND IN SAFETY STANDARD S-140 AND ENVIRONMENTAL STANDARD E-500. PROCEDURES INCLUDE THOROUGHLY WETTING THE MATERIAL TO MINIMIZE DUST, THE USE OF APPROPRIATE RESPIRATORY PROTECTION, POSTING OF APPROPRIATE SIGNS AND BARRICADING THE WORK AREA, AND DISPOSAL OF MATERIAL TO LANDFILL IN AN IMPERMEABLE CONTAINER (i.a., TIED, LABELED PLASTIC BAGS).

Care ehould be taken in the selection of these materials to ensure they will fit the application without introducing other hazards. I. DEMOLITION AND/OR MAINTENANCE Installation of asbestos insulation is prohibited in the Michigan Division. Some which was lnatallsd prior to 1969 will be encountered during demolition or maintenance operations. The following procedures shall be followed during these operatlone. These are minimum require ments and comply with OSHA standards. A. Proper caution signs shall be posted at all asbestos demolition jobs to prevent employees from entering Che area without proper respiratory protection. (Signs #77, are available from the Paint Shop, 416 Bldg., 636-1420). B. Minimize asbestos flbsra becoming air-borne. Asbestos covering and the adjacent area should be thoroughly wetted before removal to reduce the spread of dust. Do not sweep up dry fibers of asbestos. A filtered local exhaust system or vacuum should be used whenever feasible to collect the loose fibers. C. Approved dust respirators, for Instance Dustfoe 88 or 3M 8710, (available from Safety Stock,236 Bldg., 636-3842) shall be worn during all aabeatoa handling operations. Except they shall be optional where levels have been proven by monitoring to be within the standard. Respirators should be replaced (if disposable) or cleaned dally and filters replaced as needed by the users (if non-disposable). *- D. All loose asbestos waste shall be placed in properly labelled impermeable containers (at least 4 mil plastic bags) for Dow land fill disposal. When loose asbestos waste in containers is sent to landfill, special notification shall be given to Environmental Services Burner, 636-0542. Labels, bags, and tags are available from General Stock 636-3121. ( Labels stock #070205; tags, stock # 070210; bags, stock #800299). E. Clothing excessively contaminated with asbestos, as It may be in demolition, should be sent for laundering in a properly identified Impermeable bag. Disposable clothing taped cloaed at the ankles and sleeves is recommended where practicable where contamination may occur. F. Major demolition Joba shall be monitored by Industrial Hygiene to determine the amount of asbestos fibers in the work environment. II.

POLICY The Michigan Division personnel will manage the removal, disposal and general handling of friable asbestos in accordance with governmental regulations and take all other appropriate action to protect workers and the general public from asbestos hazards. II. SCOPE. This standard covers procedures for handling, transport, and disposal of asbestos as well as the required govern mental reporting. It is intended to augment not replace Safety Standard S-14PT *------------- ' " III. RESPONSIBILITY 1. Notification A. The EPA regulations on asbestos require noti fication shall be made ten (10) days prior to the start of a demolition or renovation project . where asbestos removal is involved. 1) Notification is required by the company actually doing the work. 2) Where the Dow Michigan Division is doing the work notification should be made in the format shown in Attachment A and this should be taken to Environmental Services who will, in turn, notify the U.S. EPA Region V and the Michigan Department of Natural Resources. B. The requirement that notification be made shall be a part of all contracts the Michigan Division lets for demolition or renovation where asbestos is involved. 11/82 Dow Confidential ( c E-500 Page 2 2. Renovation and demolition. A. Definitions. 1) Demolition - The wrecking or taking out of any load-supporting structural member and any related removing or stripping of friable asbestos material. 2) Renovation - The removing or stripping of friable asbestos material used to insulate or fireproof any pipe, duct, boiler, tank, reactor, turbine, furnace, or structural member. Operations in which load support ing structure members are wrecked or taken out are excluded. See demolition definition. 3) Friable Asbestos - The determination of whether asbestos is present or not can be made easily by the surface analysis group in the Analytical Laboratories, 574 Building. "Friable" simply means that the material breaks apart readily and can thus release its fiber content. B. Application 1) A 11--i t inti Jnhs involving friahle asbestos require notification. i. 2) Renovation jobs involving > 260 lineal feet^-of-- aabestos covered pipe or 160 ftJ /of^CisIrestos insulation require milifKraTlon. Jobs must not be split up 0 to get "less than" amounts. 0 C. Operating standards. 1) There shall be no visible emission to the outside air. 2) Where pipes, reactors, etc. are insulated with friable asbestos, the asbestos or the units will be removed from buildings and structures before wrecking or dismantling of any structure. 3) Adequate wetting down to prevent visible emissions will be used at all times in dis assembly, transport and disposal. 11/82 Dow Confidential ST0006439 ST0006440 E-500 Page 3 4) Visible emissions must be prevented even if wetting down is not practical. Suggested alternatives are: a) Remove large unstripped pipe sections, tanks, reactors and other equipment and strip them in areas where wetting or ventilation control i feasible. b) Use a non-freezing fluid such as brine for "wetting". Asbestos disposal sites. A. Inactive and active asbestos disposal sites will be maintained in accordance with EPA Standards 40-CFR Part 61.22L and Part 61.25 respectively. The Michigan Division landfill is maintained according to these regulations. 8. Requirements for disposition of asbestos materials are described in Environmental Standard E-110, Disposal of Demolition Materials, and Safety Standard S-140, Asbestos. 4. Compliance status reports. Compliance status reports for existing asbestos emission sources must be filed with the U.S. EPA Region V and the Michigan Department of Natural Resources. The Environmental Services Department should be contacted for content and format. The reports cover new sources and existing sources and must only be filed once unless there is a change in the emission reported. 11/82 Dou Confidential
