SAFETY DATA SHEET: PORTLAND CEMENT REVISION DATE:5/2/15 PAGE 2 <br /> Section 3 — Composition/Information on Ingredients <br /> Component/Ingredient CAS# Percent Present(Range) <br /> Portland cement 65997-15-1 100 <br /> Tricalcium silicate 12168-85-3 20-70 <br /> Dicalcium silicate 10034-77-2 10-60 <br /> Tetracalcium aluminoferrrite 12068-35-8 5-15 <br /> Gypsum(Calcium Sulfate) 13397-24-5 2-10 <br /> Tri-calcium Aluminate 12042-78-3 1-15 <br /> Limestone(Calcium Carbonate) 1317-65-3 0-20 <br /> Magnesium oxide 1309-48-4 <1-4 <br /> Nuisance Dusts(Particulates not otherwise regulated) None <1-5 <br /> Crystalline Silica(Quartz) 14808-60-7 0-<1 <br /> Other Components <br /> Cement is made from materials mined from the earth and processed using energy provided by fuels. Additional materials,such as fly ash,kiln dust and <br /> slag may also be introduced into the cement manufacturing process. A chemical analysis of cement may reveal trace amounts of naturally occurring but <br /> potentially harmful chemical compounds such as free crystalline silica,organic compounds,potassium and sodium compounds,heavy metals including <br /> cadmium,chromium(including hexavalent chromium),nickel and lead Other trace constituents may include calcium oxide(also known as free lime or <br /> quick lime)and organic compounds from grinding aids such as amine acetate salts,glycols and 1,2-ethanediol <br /> Section 4— First Aid Measures <br /> Description of First Aid Measures <br /> Eyes Rinse eyes and under lids cautiously with clean water for at least 15 minutes. Remove contact <br /> lenses,if present and easy to do.Continue rinsing. Get immediate medical advice/attention. <br /> Skin Remove contaminated clothing. Remove dry material from skin,but avoid creating dust.Wash <br /> with plenty of water. If skin irritation occurs,get immediate medical advice/attention. <br /> Inhalation Remove person to fresh air away from dust and keep comfortable for breathing. If coughing <br /> persists,obtain medical attention. <br /> Ingestion Do not induce vomiting. If subject is conscious,rinse the mouth with water to remove any <br /> material and drink plenty of water to dilute any swallowed material. Do not give drink or <br /> attempt to force water to an unconscious person. Get medical advice/attention. <br /> Important Symptoms and Effects(Acute and Delayed) <br /> Eyes Causes serious eye irritation and may scratch eye surface due to particle abrasion. May cause <br /> chemical burns resulting in corneal damage. <br /> Skin Causes skin irritation if exposed to moisture on skin creating redness,dryness and itching. <br /> Extended exposure to wet material will result in chemical burns to skin, possibly severe. <br /> Inhalation May irritate nose and throat if dust is inhaled. Prolonged or repeated inhalation of respirable <br /> dust may lead to respiratory tract or lung damage. <br /> Ingestion May cause irritation and burns of mouth,throat,stomach and digestive tract if swallowed. <br /> Recommendations for Immediate Medical Care or Special Treatment <br /> Seek immediate medical attention for inhalation of large quantities of dust or exposure of wet material over large areas of skin. <br /> Seek immediate medical attention if material comes into contact with eyes and cannot be immediately removed. <br /> Section 5 — Fire Fighting Measures <br /> General Fire Hazards None. Material is not considered flammable or combustible. <br /> Extinguishing Media Use water or water spray to extinguish any fires involving this material. <br /> Extinguishing Media to Avoid None. <br /> Hazards of Combustion None. <br /> Fire Fighting Recommendations Firefighters should always wear full protective gear to fight any fire. <br /> Refer to Section 9 for flammability information. <br />
