These MSHS's have been developed to provide the information required to comply with the OSHA Hazard Communication Regulations due to go into effect in late 1985. you are requested at this time to approve them for pub lication and distribution. We seek final approval >* you may provide editorial suggestions or comments for the record only, but please do not suggest substantive changes unless you feel strongly that they need to be made. documentation mill be required for any suggested changes to be made at this time. An approval sheet is attached for both MSHS's,' please sign and date in the appropriately marked spaces and return to me by September 28, 1984-. This will speed the publication process to ensure Marketing can receive final copies early October. Modifications have been made in response to various suggestions received on the preliminary drafts. Where changes were involved, revisions have generally been discussed with the person making the suggestion. The two MSHS's differ only on the first page in Section Z - Product Identification, Section 11 - Physical Hata (size and density), and Section 111 - Hazardous Ingredients, Magnetite vs Amorphous Silica. It was Judged to be easier to use separate MSHS's than try to combine them and still make the information clear. Please review and return the approval sheet by September 28 to ensure dissemination to Marketing shortly thereafter. <5SR ew Att. *420318 FINAL DRAFT IP. C.

Extreme exposures can overwhelm the normal respiratory defense mechanisms and result in temporary difficulty in breathing. Skin Contact: Asbestos splinters may penetrate the skin .and cause asbestos "corns." Skin Absorption: Not applicable. Eye Contact: May cause irritation and abrasions. Ingestion:________ No known effects._________________________________________________________________________ CHRONIC EFFECTS OF OVEREXPOSURE Route of Exposure: Inhalation: Overexposure to Chrysotile Asbestos has caused damage to lungs (asbestosis), lung cancer and mesothelioma of the pleura and peritoneum. Symptoms, which are usually not manifested until 15-20 years after exposure, include labored breathing, chest pains, weakness, and chest tightness. Pleural thickening, plaques and effusion are nondisabling conditions, seen separately or together, that have been associated with prolonged asbestos exposure. The risk of lung cancer is greatly increased for those who smoke cigarettes regularly in addition to having asbestos exposures. Skin Contact: Not applicable. Skin Absorption: Not applicable. Eye Contact: Same as acute effects. Usually reversible on removal from exposure. Ingestion: Most studies indicate that asbestos overexposure is not implicated as a cause of gastro-intestinal and laryngeal cancers, but the evidence is ________________________ conflicting. EMERGENCY AND FIRST AID PROCEDURES Route of Exposure: Inhalation: No acute toxicity: Remove to fresh air. If breathing is difficult, oxygen may be administered. If breathing has stopped, administer artificial respiration. Call a physician. Skin Contact: Remove asbestos slivers promptly. If "asbestos corn" develops, surgical removal may be required. Eye Contact: Irrigate gently with water for 15 minutes. Refer to ophthalmologist to rule out possibility of damage to cornea or eyeball by fibers. Ingest ion:_________ None indicated.__________________________ NOTES TO PHYSICIAN A medical surveillance program must be established for asbestos-exposed persons in accordance with the requirements of the Occupational Safety and Health Administration's standard for Asbestos (29 CFR Part 1910.1001). X42082I SECTION V FIRE AND EXPLOSION DATA Combustibility: Hot combustible.Flaamable Limits: Not applicable. Flash Point (Test Method): Not applicable. Autoignition Temperature: Not applicable. Explosion Tendency: Not applicable. Extinguishing Media: Use media appropriate for surrounding material in fire situation. Special Fire-Fighting Procedures: Avoid media and procedures that cause airborne dust. Personnel involved in fire-fighting should use NIOSH/MSHA-approved self-contained breathing apparatus and full protective clothing. Unusual Fire and Explosive Hazard: See above.___________________________________________ ________ __ SECTION VI REACTIVITY DATA Stability: Stable (Temperatures in excess of 1112 F (600 C) cause loss of bound water). Condit ions to Avoid: None. Hazardous Decomposition Products: None. Material to Avoid: None. SECTION VII SPILL. LEAK, AND DISPOSAL INFORMATION Steps to be Taken if Material is Spilled or Released: Avoid breathing dust. Notify Safety personnel of spill. Permit only trained clean-up personnel in the spill area. Use wet methods or approved vacuum cleaning system to pick up spilled materials. Use water or other dust suppressants where sweeping is unavoidable. Do not stir up dust. Clean-up personnel should wear approved respirators and protective clothing. Waste and contaminated protective clothing must be placed in dust-tight containers and be properly labeled for disposal. Neutralizing Agents: Not applicable._________________________________________________________________ ________ Waste Disposal Method: Bags, friable asbestos, waste and scrap material should be disposed of in a manner which will avoid airborne concentrations of asbestos, such as the use of dust-tight trash bags or containers. Such containers should be labeled in accordance with 40 CFR 61.20. Asbestos is also classified as a hazardous material under CWA 307(a) and has a reportable quantity of one pound. Deposit waste containers in a secured landfill in accordance with Federal, State, and __________________ local regulations.______________________________________________________________________ .______ SECTION VIII SPECIAL PROTECTION INFORMATION Ventilation: ________ Provide adequate exhaust ventilation and capture filtration to remove asbestos particulate from the workplace and minimize its dispersion into the environment. Isolate work areas and post signs where asbestos contamination may exceel PEL. Hand- or power-operated tools which may release asbestos in excess of the PEL must be equipped with local exhaust systems._____________________ X420822 SECTION VIII SPECIAL PROTECTION INFORMATION (Continued) Personal Protective Equipment: Respiratory Protection (Type): Where asbestos exposure in excess of the permissible limits is anticipated, wear a NIOSH/MSHA-approved respirator; a reusable or single-use air purifying respirator up to 10 times the PEL; a powered air purifying respirator up to 100 times the PEL; a continuous-flow or pressure-demand Type C supplied air respirator for greater than 100 times the PEL. Eye Protection: Goggles are recommended. Follow Safety Rules. Gloves/Clothing: Cloves are recommended during handling. Other: For concentrations in excess of the ceiling limit special clothing, such as coveralls, whole-body clothing, head coverings, gloves, and foot coverings are required under CFR 1910.1001.________________ SECTION IX SPECIAL PRECAUTIONS Precautionary Statements: WARNING CANCER HAZARD Breathing asbestos dust can cause lung damage and cancer. cancer is greatly increased for smokers. The risk of lung Do not create or breathe dust. Do not dry-sweep or use air hose for cleaning. Do not take protective equipment or clothing home. Do follow recommended work practices. Do wear approved respiratory protection and protective clothing as required by applicable regulations. Do use vacuum or wet cleaning methods. Do dispose of dust, friable waste materials and contaminated protective equipment in dust-tight containers. FOR INDUSTRIAL USE ONLY Precautions for Handling and Storage: Store asbestos in closed containers (dust-tight) in a clean, dry, secure area. 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 at all stages of asbestos handling, use and disposal. Follow good housekeeping practices to prevent accumulation of asbestos-containing dusts. Avoid inhalation of asbestos. __________________ Other Precautions: Material Listed as Carcinogen in: National Toxicology Program Annual Report (NTP): Known carcinogen.
