This product is not expected to produce any unusual hazards during normal use. Exposure to high dust levels may irritate the skin, eyes, nose, throat, or upper respiratory tract. This product is formulated to reduce airborne sanding dust and therefore significantly reduces the risk of exposure to high dust levels. POTENTIAL HEALTH EFFECTS (See Section 11 for more information) ACUTE : Inhalation Exposure to dust generated during the sanding of the product may irritate eyes, skin, nose, throat, and upper respiratory tract. Persons subjected to large amounts of this dust will be forced to leave area because of nuisance conditions such as coughing, sneezing and nasal irritation. Labored breathing may occur after excessive inhalation. If respiratory symptoms persist, consult physician. This product is formulated to reduce airborne sanding dust and therefore significantly reduces the risk of inhalation of large amounts of dust. Eyes Dust can cause mechanical irritation of eyes. If burning, redness, itching, pain or other symptoms persist or develop, consult physician. Skin None known. Ingestion None known. CHRONIC: Inhalation Prolonged and repeated exposure to airborne free respirable crystalline silica can result in lung disease (i.e., silicosis) and/or lung cancer. The development of silicosis may increase the risks of additional health effects. The risk of developing silicosis is dependent upon the exposure intensity and duration. Eyes None known. Skin None known. Ingestion None known. TARGET ORGANS: Eyes, skin and respiratory system.

If user operations generate airborne dust, use ventilation to keep dust concentrations below permissible exposure limits. Where general ventilation is inadequate, use process enclosures, local exhaust ventilation, or other engineering controls to control dust levels below permissible exposure limits. RESPIRATORY PROTECTION: Wear a NIOSH/MSHA-approved respirator equipped with particulate cartridges when dusty in poorly ventilated areas, and if TLV is exceeded. A respiratory program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements must be followed whenever workplace conditions warrant a respirator's use. If engineering controls are not possible, wear a properly fitted NIOSH/MSHA-approved particulate respirator. OTHER PERSONAL PROTECTIVE EQUIPMENT: Eye/Face Wear eye protection, safety glasses or goggles, to avoid possible eye contact. Skin Wear gloves and protective clothing to prevent repeated or prolonged skin contact. General Selection of Personal Protective Equipment will depend on environmental working conditions and operations.

HAZARDOUS DECOMPOSITION Above 800º C – limestone may decompose to calcium oxide (CaO) and carbon dioxide (CO2). Above 175º C – polyvinyl acetate may decompose to H2O, CO2, CO, and acetic acid, could produce vinyl acetate monomers. SECTION 11 TOXICOLOGICAL INFORMATION ACUTE EFFECTS: None known. CHRONIC EFFECTS / CARCINOGENICITY: Vinyl acetate/acetaldehyde/formaldehyde: Ethylene vinyl acetate polymer is a common emulsion polymer most familiar as the component of ordinary white glue which exhibits the “sticky” characteristic. Ethylene vinyl acetate polymer is not classified as a carcinogen by IARC, NTP or ACGIH. Trace amounts of residual vinyl acetate monomers, acetaldehyde and formaldehyde may be associated with the production of ethylene vinyl acetate polymer. Any exposure to vinyl acetate monomer, acetaldehyde, or formaldehyde is expected to remain well below OSHA regulatory and ACGIH recommended limits during normal handling and use of this product. Crystalline Silica: Industrial hygiene atmospheric respirable crystalline silica testing did not detect any respirable crystalline silica during the sanding of SHEETROCK® Brand Lightweight All Purpose Joint Compound Ready Mixed Plus 3 with Dust Control. Samples taken within the breathing zone of workers while sanding on the jobsite were collected and analyzed according to NIOSH test methods 600 and 7500. Exposures to respirable crystalline silica are not expected during the normal use of this product; however, actual levels must be determined by workplace hygiene testing. Prolonged and repeated exposure to airborne free respirable crystalline silica can result in lung disease (i.e., silicosis) and/or lung cancer. The development of silicosis may increase the risks of additional health effects. The risk of developing silicosis is dependent upon the exposure intensity and duration. In June, 1997, IARC classified crystalline silica (quartz and cristobalite) as a human carcinogen. In making the overall evaluation, the IARC Working Group noted that carcinogenicity in humans was not detected in all industrial MATERIAL SAFETY DATA SHEET CGC Dust Control™ Drywall Compound MSDS #61-362-002 Page 6 of 9 circumstances studied. Carcinogenicity may be dependent on inherent characteristics of the crystalline silica or on external factors affecting its biological activity or distribution of its polymorphs. IARC states that crystalline silica inhaled in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1).
