Skin: May cause irritation. Repeated exposure may cause skin dryness or cracking. Inhalation: This product contains mineral spirits. Breathing high concentrations of vapor may cause respiratory irritation, headache, nausea or vomiting. Oxygen depravation is possible if working in confined spaces. Ingestion: Ingestion and subsequent aspiration into the lungs may cause lung damage. Long Term Health Effects: Skin: Repeated skin contact may cause sensitization. Inhalation: None. Ingestion: Ingestion and subsequent aspiration into the lungs may cause lung cavity formation and chronic lung dysfunction. Page 1 of 5
Signs and Symptoms of Overexposure: Medical Conditions Aggravated by Exposure: If material enters lungs, signs and symptoms may include coughing, choking, wheezing, difficulty in breathing, chest congestion, shortness of breath and/or fever. Defatting dermatitis signs and symptoms may include a burning sensation and/or a dried cracked appearance. Skin irritation signs and symptoms may include a burning sensation, redness, swelling and/or blisters. Pre-existing medical conditions of the skin may be aggravated by exposure to this material. Section 3 Composition / Information on Ingredients---------------------------------- CAS Number Component Name Weight % 1317-65-3 Limestone 30-40% 14807-96-6 Magnesium silicate 10-20% 64742-47-8 Petroleum hydrocarbon solvent 10-20% 112926-00-8 Hydrated amorphous silica 0-5% 64741-88-4 Severely refined paraffinic oil 0-5% Section 4 First Aid Measures------------------------------------------------------------- Eye: Skin: Inhalation: Ingestion: Physicians: Flush with water for 15-minutes. Seek medical attention if mechanical irritation occurs. Remove from skin and wash with soap and water. Difficult to remove material may require the use of mineral spirits to remove residue. Get medical attention if irritation develops. If affected, remove to fresh air. Give oxygen as necessary. Seek medical attention if conditions persist. Do not induce vomiting. If vomiting occurs spontaneously, keep head below hips to prevent aspiration. Get medical attention immediately. Potential for chemical pneumonitis. Treat according to the patient s condition and specifics of exposure. Section 5 Fire Fighting Measures-------------------------------------------------------- Flash Point: >142 F Auto ignition Temperature: 455-599 F Flammability Limits in Air: 0.7 6% by volume Extinguishing Media: For small fires use carbon dioxide (CO 2 ), dry chemical or water spray. For large scale fires, use dry chemical, foam or water spray. Fire Fighting Measures: Self-contained breathing apparatus and protective clothing should be worn in fighting large fires. Determine the need to evacuate or isolate the area according to your local emergency plan. Use water spray to keep exposed containers cool. Unusual Fire Hazards: None. Hazardous Decomposition: Thermal breakdown of the product during fire or very high heat conditions may evolve the following: carbon monoxide, carbon dioxide and isobutene. Page 2 of 5
