Dry Chemical Water Fog Other Unusual Fire and Explosion Hazards: None Special Firefighting Procedures: None Section V -- HEALTH HAZARD DATA Effects of Overexposure: Acute - May cause eye and/or skin irritation. Chronic - Overexposure to asbestos can cause asbestosis, a scarring of the lungs. Pleural thickening, effusion, and plaques are nondisabling conditions, seen separately or together, that have been associated with asbestos exposure. The International Agency for Research on Cancer (IARC) has determined that there is sufficient evidence for the carcino genicity of asbestos in humans. Signs and Symptoms of Overexposure: Asbestosis is associated with symptoms of labored breathing, chest pain, weakness and chest tightness. Symptoms are not usually manifest until 15-20 years after exposure. Primary Route(s) of Entry: Dermal Inhalation Ingestion Emergency and First Aid Procedures: Remove asbestos slivers from skin promptly. In case of eye irritation, gently rinse with water. If irritation persists, get medical help. Special Note: A medical surveillance program must be established for asbestos-exposed persons in accordance with the require ments of the Occupational Safety and Health Administration's standard for asbestos (29 CFR Part 1910.1001). SECTION VI -- REACTIVITY DATA Stability: Stable Hazardous Polymerization: Will Not Occur Hazardous Decomposition Products: None Conditions to Avoid: Avoid creating and breathing dust. Incompatibility (Materials to Avoid): None D 004152 Material Safety Data Sheet November 12, 1985 Page 3 SECTION VII -- SPILL OR LEAK PROCEDURES Steps to be Taken in Case Material is Released or Spilled: Avoid creating dust. Collect dust by HEPA vacuum or in the wet state (wet sweeping, wet wiping) to prevent emission of airborne fibres.

To be an acceptable jits for disposal of asbestos-containing waste material under || 61.151 and 61.152. an active waste disposal site must meet the requirements of this section. (a) Either there must be no visible emissions to the outside sir from any active waste disposal site where asbestos-containing waste material bee been deposited, or the requirements of paragraph (c) or (d) of this section must bemeL (b) Unless a natural barrier adequately deters access by the general public, either warning signs and fencing must be installed and maintained as follows, or the requirements of paragraph (c)(1) of this section must be met (1) Warning signs must ba displayed at aU entrances and at intervals of 100 m (330 ft) or less along the property line of the site or along the perimeter of the sections of the site where asbestoscontaining waste material is deposited. The warning signs must: (i) Be posted in such a manner and location that a person can easily read the legend; and (ii) Conform to the requirements of 51 cm x 36 cm (27* x 14") upright format signs specified in 29 CFR 1910445(dU4) end this paragraph: and (iii) Display the following legend in the lower panel with letter sizes and styles of e visibility at least equal to those specified in this paragraph. (3) Upon request and supply of appropriate information, tbs Administrator will determine whether s fence or a natural barrier adequately deters access by tbs general public (c) Rather than meet the no visible emission requirement of paragraph (a) of this sactiod) an active waste disposal sits would be an acceptable site if at the end of each operating day. or at least ones every 24-hour period while the site is in continuous operation, the asbestoscontaining waste material which wee deposited at the aits during ths operating day or previous 24-hour period is covered with either. (1) At least IS centimeters (0 inches) of compacted nonasbestos-containing material, or. (2) A resinous or petroleum-based dust suppression agent that effectively ' binds dust and controls wind erosion. This agent must be used ss recommended for the particular dust by the manufacturer of the dust suppression agent. Other equally effective dust suppression agents may be used upon prior approval by the Administrator. Foe purposes of this paragraph, waste crankcase oil is not considered s dust suppression agent. (d) Rather than met! the no visible emission requirement of paragraph (a) of this section, an active waste disposal site would be an acceptable site if an alternative control method for emissions that has received prior approval by the Administrator Is used.

Powered air-purifying respirator -- for exposures more than 10X, but less than 100X, the PEL. Type "C" continuous flow or pressure-demand, supplied-air respirator -- for exposures more than 100X the PEL. All respirators must be NIOSH/MSHA approved. Ventilation: Local ventilation if engineering controls are inadequate. Protective Gloves: (See "Other Protective Equipment") Eye Protection: (See "Other Protective Equipment") Other Protective Equipment: If the ceiling concentration limit is exceeded, clothing provid ing whole body covering shall be supplied and its use required. Hygienic Practices: Do not create or breathe dust. ' Do not dry sweep or use air hose for cleaning. Do not take protective equipment or clothing home. (See attached pamphlet, "Recommended Practices for Handling Asbestos Fiber".) SECTION IX -- SPECIAL PRECAUTIONS Precautions to be Taken in Handling and Storing: Use no hooks in loading and unloading. Protect containers from damage. Do not open containers in a manner that can release dust without providing proper enclosure or control measures. Use dust suppression control measures, such as ventilation or wet-working, at all stages of asbestos handling, use and disposal. Follow good housekeeping practices, such as wet-wiping dusty surfaces, to prevent accumulation of asbestos-contain ing dust. Avoid inhalation of asbestos. Other Precautions: Smoking greatly increases risk to health. While the information and recommendations set forth herein are believed to be accurate as of the date hereof, CALAVERAS ASBESTOS, LTD.

Any spillage of ip immediately -- after thoroughly 1 be deposited in tions governing s on discharge codes, rules or and use of UNLOADING Unitized loads should be fitted intact to and from holds of ships, and off and on land transport by forklift trucks or other suitable handling equipment. Care should be taken to avoid puncturing the asbestos fiber bags during unloading from ships, rail road cars, trucks or other modes of transportation. Hooks or other sharp instruments should not be used. Loose fiber accumulated during transit should be picked up by vacuum cleaner before unloading. STORAGE For storage, fiber bags should be stacked and moved with care to avoid breakage; protected from, puncture by moving vehicles; and, if possible, should be isolated from traffic in the warehouse and covered to prevent dust generation. To prevent deterioration of stored bags, the principle of first-in, first-out should be followed. HANDLING Maximum possible enclosure and fully effective dust control systems should be provided at all stages of in-plant handling where dust is created, such as in bag opening, fiber dumping and bag disposal oper ations. Loose fiber should be cleaned from work areas by vacuum cleaner, or after thoroughly wetting, by sweeping, and then deposited in covered recep tacles. PROTECTIVE EQUIPMENT Wearing of respiratory equipment approved for pro tection against asbestos dust should be required at all stages of asbestos fiber handling where quantities of dust are generated which cannot be kept within the permissible exposure limits by dust control equip ment or other methods. TRANSPORT Where the use of asbestos requires the transport of loose fiber in open carts or buggies, covers should be used to prevent spilling and dust generation. WASTE MATERIALS Waste materials, such as collected dust and empty fiber bags, should be placed in special closed receptacles and disposed of in such a manner as to prevent the release of dust. Safety practices outlined above in the HANDLING and PROTECT/VE EQUIP MENT sections should be followed during these operations. Ail dust from exhaust systems should be collected and safely disposed of, being careful not to release dust into the outside air. Particular attention should be paid to the protection of employees whose job it is to dispose of collected dust from fabric filter dust collection and similar cleaning operations. t Calaveras Asbestos Ltd.
