Ready Mix Concrete Safety Data Sheet -nrding To Federal Register/Vol.77,No.58/Monday,March 26,2012/Rules And Regulations And According To The Hazardous Products Regulation (February 11,2015). mmability(solid,gas) Not available Lower Flammable Limit Not available Upper Flammable Limit Not available Vapor Pressure Not available Relative Vapor Density at 20°C Not available Relative Density Not available Specific Gravity Not available Solubility Not available Partition Coefficient:N-Octanol/Water Not available Viscosity Not available SECTIONSTABILITY 10.1. Reactivity: Reacts slowly with water forming hydrated compounds, releasing heat and producing a strong alkaline solution until reaction is substantially complete. May react exothermically with water releasing heat.Adding an acid to a base or base to an acid may cause a violent reaction. 10.2. Chemical Stability: Stable under recommended handling and storage conditions(see section 7). 10.3. Possibility of Hazardous Reactions: Hazardous polymerization will not occur. 10.4. Conditions to Avoid: Direct sunlight, extremely high or low temperatures,and incompatible materials. 10.5. Incompatible Materials: Wet cement and cement clinker is alkaline and is incompatible with acids, ammonium salts and aluminum metal. Cement dissolves in hydrofluoric acid, producing corrosive silicon tetrafluoride gas. Cement reacts with water to form silicates and calcium hydroxide. Silicates react with powerful oxidizers such as fluorine, boron trifluoride,chlorine trifluoride, manganese trifluoride, and oxygen difluoride. 10.6. Hazardous Decomposition Products: Thermal decomposition generates: Carbon oxides(CO,CO2). Silicon oxides. corrosive vapors. •N 11:TOXICOLOGICAL INF• • 11.1. Information on Toxicological Effects-Product Acute Toxicity(Oral): Not classified Acute Toxicity(Dermal): Not classified Acute Toxicity(Inhalation): Not classified LD50 and LC50 Data: Not available Skin Corrosion/Irritation:Causes severe skin burns and eye damage. pH: 12- 13 in water Eye Damage/Irritation:Causes serious eye damage. pH: 12-13 in water Respiratory or Skin Sensitization: May cause an allergic skin reaction. Germ Cell Mutagenicity: Not classified Carcinogenicity: Not classified. Specific Target Organ Toxicity(Repeated Exposure): Not classified. Reproductive Toxicity: Not classified Specific Target Organ Toxicity(Single Exposure): Not classified. Aspiration Hazard: Not classified Symptoms/injuries After Inhalation: May be corrosive to the respiratory tract. Symptoms/Injuries After Skin Contact:Corrosive. Causes burns. Redness, pain,swelling, itching, burning, dryness, and dermatitis. May cause an allergic skin reaction.When this product is wet it is corrosive. Symptoms/Injuries After Eye Contact:Causes serious eye damage. Redness, pain, swelling, itching, burning,tearing,and blurred vision. Causes permanent damage to the cornea, iris,or conjunctiva. Symptoms/Injuries After Ingestion: May cause burns or irritation of the linings of the mouth,throat,and gastrointestinal tract. 'hronic Symptoms: If dust is generated, repeated exposure through inhalation may cause cancer or lung disease. Pre-existing lung .seases such as emphysema or asthma may be aggravated by exposure to dusts. Pulmonary function may be reduced by inhalation of respirable crystalline silica.Also lung scarring produced by such inhalation may lead to a progressive massive fibrosis of the lung which may aggravate other pulmonary conditions and diseases and which increases susceptibility to pulmonary tuberculosis. Progressive massive fibrosis may be accompanied by right heart enlargement, heart failure,and pulmonary failure.Smoking 04/13/2017 EN(English US) 7/10
