OCCUPATIONAL HEALTH PROCEDURE #145 SABINE RITE?. WORKS SAFETY MANUAL ASBESTOS HANDLING AND DISPOSAL Reviewed or Revised 1/17/84 page i of 9 PURPOSE This procedure presents the per missible asbestos dust exposure limits, methods of controlling exposure, respiratory protective equipment, disposal, and methods of handling. The principle sources of exposure to airborne asbestos dust at Sabine River Works have been: 1) Removing old insulation; 2) filter aids; 3) waste dis posal; 4) mixing asbestos cement; 5) cutting transite; 6) removal of clothing after completing asbestos insulating duties; 7) working with asbestos type packing and gasket material. A. DEFINITIONS 1. Asbestos Material - Any material containing asbestos. 2. Particulate Asbestos Material - Finely divided particles of asbestos material. 3. Visible Emissions - Any emissions which are visually detectable without the aid of instruments and which contain particulate asbestos material. 4. Removal - The taking down or stripping of Friable Asbestos Material. NOTES AND REFERENCES ----------------------------------------------- Reference Du Pont Engineer ing Standard S4T. OSHA Regulation, Section 1910.1001 (ETS) dated November 4, 1983, and 1910.141. "Asbestos dust concentrations in air shall not exceed one-half (0.5) fiber, longer than 5 micrometers, per cubic centimeter of air. At no time may the concentration exceed a ceiling of 10 fibers longer than five (5) micrometers per cubic centimeter".

Friable Asbestos - Any material that contains more than 1% asbestos by weight and can be crumbl ed, pulverized, or reduced to powder when dry, by hand pressure. (Transite is not friable asbestos material.) .NOTES AND REFERENCES Transite is friable only when it is being cut. 6. Wet method - Sufficiently coated with water to pre vent dust emissions. B. GENERAL RULES 1. Material containing asbestos shall not be used where there are satisfactory substitutes. Any insulation not known to be free of asbestos will be considered to contain asbestos for purposes of this pro cedure. 2. Each job involving the handling of asbestos must be thoroughly reviewed. 3. Insulation to be removed and discarded should be adequately wetted prior to and during removal. Material removed shall not be dropped or thrown to the ground, but shall be carefully lowered to ground level. 4. Each employee handling asbestos or exposed to the dust must wear an approved respirator, trained in it's use, and fit-tested. The 3M respirator, Type 8710 is approved for use, CTI-87-50-450. Contact the Safety Division for other approved respirators and filters. If concentra tions are expected to ex ceed 100 times the TLV, then an atmosphere supply ing respirator must be used. : ttiV^ST.usr'z. *-3n&-- "ELr-.'W OCCUPATIONAL HEALTH PROCEDURE #145 ASBESTOS HANDLING AND DISPOSAL Page 3 of 9 5. Asbestos free insulation will be used on all new or altered facilities. 6. All hand operated or power operated tools which may produce or release asbestos fibers in excess of the permissible exposure limits shall be provided with a dust catching system. NOTES AND REFERENCES Vacuum area daily to prevent accumulation of asbestos dust on ledges, shelves, floors, and machines. Air hoses or dry sweeping is not permitted. 7. Asbestos in the work place must be maintained in a "bound" condition. If asbestos is found in an un bound condition, it must either be removed or re bonded. 8. If there is a delay in doing either of the things required in paragraph 7, caution label as specified in Figure 2, Page 6 of this procedure is required. Monitoring results as outlined in Paragraph G is also required. C. WORK PRACTICES Bonding of asbestos contain ing insulation consists of 1) wrapping with aluminum or plastic sheathing or 2) wrap ping with fiber glass cloth and then either brushing, rolling, or spraying on an insulating mastic material, or 3) application of a bond ing agent, coating, mudding, etc. Small tubing that has been wrapped with asbestos tape or sleeve material must be sealed with a waterproof material such as Lagtone. 1. The minimum requirements for any job involving asbestos are: a) Use of wet method. b) Use approved respirator. c) Proper waste disposal. d) Caution label if unbound asbestos is left over night. Where measurements on a pre vious job of the same or a similar nature demonstrated asbestos concentrations with in allowable limits. Ref. par. E of this procedure Ref. fig. 2 page 8 of this procedure. 2. If the job involves more than two manhours or if unusual dusting is anticipat ed, the following precautions must be considered along with those listed in paragraph C above.

Any dried out cement should be discarded. Do not attempt to rework it. c. E. WASTE DISPOSAL .1 Pipes and equipment in sulated with asbestos will require special handling to meet waste disposal criteria. a. If the material is stripped in place or immediately after removal, the group doing the work must adhere to the work practices out lined in par. C of this procedure. b. Equipment covered with This can be accomplished by asbestos must be tempor wrapping with polyethylene arily bound and labeled and taping each individual prior to being transported portion that is not in a on the plant.

HYGIENE NOTES AND REFERENCES 1. Separate lockers for work clothes and street clothes must be provided to prevent contamination for known exposure to high level concentrations. 2. Special clothing (coveralls) should also be provided for high concentrations such as spraying and demolition of asbestos insulation. 3. Food, gum, tobacco, or any edibles shall not be con sumed in areas where asbestos is being handled or fabricated. SAMPLING Monitoring is required where employees might be exposed to asbestos dust to determine the amount of exposure. H. IDENTIFICATION OF INSULATION Intervals between monitor ing of samples shall not exceed six months. Contact the Industrial Hygiene Monitoring Group, Building #5 for assistance. 1. All insulation that is not marked is to be handled as containing free asbestos until proven otherwise. 2. All newly installed in sulation will be marked as follows: a. All non-asbestos material should be identified by the vendor with a green stripe.
