Removal - The taking down or stripping of Friable Asbestos Material. 5. Friable Asbestos - Any material that contains asbestos and can be crumbled, pulverized, or reduced to powder when dry, by hand pressure. (Transite is not friable asbestos material.) 6. Wet method - Sufficiently coated with water to prevent 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 procedure. 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. o Transite is friable only when it is being cut.

Each employee handling asbestos or exposed to the dust must wear an approved respirator, trained in it's use, and fit-tested. o The 3M respirator. Type 8710 is approved for use, CTI-87-50-450. Contact the Safety Division for other approved respirators and filters. If concen trations are expected to exceed 100 times the TLV, then an atmosphere supply ing respirator must be used. 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. o Accumulation of asbestos dust on ledges, shelves, drawers, floors, and machines can be avoided by vacuuming the area. 7. Asbestos insulation in the o Bonding of asbestos workplace must be maintained containing insulation in a 'bound" condition. If consists of 1) wrapping asbestos is found in an un with aluminum or plastic bound condition, it must sheathing or 2) wrapping either be removed or rebonded with fiber glass cloth and then either brushing, 8. if there is a delay in doing rolling, or spraying on either of the things required am insulating mastic in Paragraph 7, caution material, or 3) applica label as specified in tion of a bonding agent, Pigure 2, of this coating, mudding, etc. DUP 0908709 OCCUPATIONAL HEALTH PROCEDURE *145 ASBESTOS HANDLING AND DISPOSAL Pagg 4 of 10 __________________ July 25. 1985 NOTES AND REFERENCES- procedure is required. Monitoring results as out lined in Paragraph G is also required. 9. Asbestos containing gaskets or gasket material must be stored in plastic sheathing and vacuumed to prevent accumulation of dusts. The gasket storage cabinets or drawers must be labeled clearly to identify the contents. C. WORK PRACTICES 1. The minimum requirements for any job involving asbestos insulation are: a) Use of wet method. b) Use approved respirator. c) Proper waste disposal. d) Caution label if un bound asbestos is left overnight. 2. If the job involves more than two manhours or if unusual dusting is antici pated, the following precautions must be considered along with those listed in Paragraph C above. a) Monitoring b) Use of protective clothing. c) Barricades and posting of temporary warning signs. Small tubing that has been wrapped with asbestos tape or sleeve material must be sealed with a water proof material such as Lagtone*. o Where measurements on a previous job of the same or a similar nature demonstrated asbestos concentrations within allowable limits. o Ref.
