C Melting/Freezing Point Not Available Vapour Density (Air = 1) > 1 Specific Gravity (g/cc) 1.13 Vapour Pressure (mm Hg) Not Available Evaporation Rate, n-Butyl Acetate = 1 Not Available PH < 1.0 Solubility in Water Soluble 4. FIRE AND EXPLOSION DATA Flammability Limits in Air (%): Not Applicable Extinguishing Media: Use media appropriate for surrounding fire or materials. Do not use water. Flash Point (TCC deg. C): Not Applicable. Autoignition Temperature (deg. C): Not Available. Hazardous Combustion Products: Hydrogen gas, sulphur oxides, phosphorus oxide, carbon monoxide. Sensitivity to Mechanical Impact: Not available. Not expected to be sensitive to mechanical impact. Rate of Burning: Not available. Explosive Power: Not available. Sensitivity to Static Discharge: Not available. Not expected to be sensitive to static discharge. Unusual Fire Hazard: Reacts with most metals to produce - 2 - hydrogen gas which could make an explosive mixture with air. Contents may develop pressure on prolonged exposure to heat. 5. REACTIVITY DATA Chemical Stability: Yes, under normal conditions. Compatibility with Other Substances: No, with metals, strong oxidizing agents, reducing agents, Lewis or mineral acids, strong bases. Hazardous Products of Decomposition: Flammable hydrogen gas, sulphur oxides, carbon monoxide, oxide of phosphorus. Hazardous Polymerisation: Will not occur. 6. TOXICOLOGICAL PROPERTIES Route of Entry: Skin Contact: Yes Skin Absorption: Yes Eye Contact: Yes Inhalation: Yes Ingestion: Yes Effects of Exposure: Corrosive! Toxic or fatal if swallowed, effects may be delayed. Causes severe burning and pain in the mouth, throat and abdomen. Causes severe skin and eye burns. May cause blindness. Harmful if inhaled. Product is extremely irritating to the eyes, nose, throat and respiratory tract. Carcinogenicity of material: Sulfuric acid as aerosol or mist is classified as suspected carcinogen by ACGIH and IARC. Reproductive effects: No information is available and no adverse Reproductive effects are anticipated. Teratogenicity: No information is available and no adverse Teratogenic effects are anticipated. Mutagenicity: No information is available and no adverse Mutagenic effects are anticipated. 7. PREVENTIVE MEASURES - 3 - Eye Protection: Safety glasses are required. Use full face-shield and chemical safety goggles when there is potential for contact. Contact lenses should not be worn when working with this material. Skin Protection: Gloves and protective clothings made from butyl rubber should be impervious under condition of use. Discard contaminated gloves. Respiratory Protection: A NIOSH/MSHA-approved full facepiece air- purifying respirator equipped with acid gas, dust, mist, fume cartridge for concentrations up to 10 mg/m3 Sulfuric Acid. Wear air-supplied respirator if concentrations are higher of unknown. Other Personal Protective Equipment: Wear an impermeable apron and boots. Locate safety showers and eyewash station close to chemical handling area. Engineering Controls: Local exhaust ventilation required, it should be corrosion proof. Leak/Spill Clean-Up Procedures: Use calcium hydroxide (hydrated lime) to neutralize to a pH between 7 and 9. Check for neutral pH using pH paper. Neutralization is expected to be exothermic. Ventilate enclosed spaces. Collect product for disposal. Dispose of waste material at an approved hazardous waste treatment/disposal facility in accordance with applicable local, provincial and federal regulations. Do not dispose of waste with normal garbage, or to sewer systems. Notify applicable government authority if release is reportable or could adversely affect the environment. Storage Instructions: Store in clean, cool well ventilated are away from strong bases, metal powders, carbides, sulphides and any readily oxidizable material. Protect from physical damage.
