Material Safety Data Sheet Material Name: Aluminum Sulfate Distributed by: Rocky Mountain Reagents, Inc Part Number: A1055 ID: C1 -166 * * Section 8 - Exposure Controls / Personal Protection (Continued) Personal Protective Equipment: Skin Where contact is likely, wear chemical resistant gloves, rubber boots, and coveralls. Butyl rubber, natural rubber, polyethylene, polyvinyl chloride or neoprene gloves are recommended. Polyvinyl alcohol and very thin rubber, nitrile, or PVC gloves are NOT recommended. Gloves should be tested to determine suitability for prolonged contact with this material. If necessary, refer to U.S. OSHA 29 CFR 1910.138. Personal Protective Equipment: Respiratory None required where adequate ventilation conditions exist. If airborne concentrations are above the applicable exposure limits, use NIOSH approved respiratory protection. Currently, there are no NIOSH respiratory guidelines for this material. NIOSH guidelines for sulfuric acid may be appropriate, depending on use of Aluminum Sulfate. If respiratory protection is needed, use only protection authorized in the U.S. Federal OSHA Standard (29 CFR 1910.134), applicable U.S. State regulations. Oxygen levels below 19.5% are considered IDLH by OSHA. In such atmospheres, use of a full - facepiece pressure /demand SCBA or a full facepiece, supplied air respirator with auxiliary self - contained air supply is required under OSHA's Respiratory Protection Standard (1910.134- 1998). Personal Protective Equipment: General Wash hands thoroughly after handling material. Do not eat, drink or smoke in work areas. Have a safety shower or eye -wash fountain available. Use good hygiene practices when handling this material including changing and laundering work clothing after use. Discard contaminated shoes and leather eoods. 11 * * * Section 9 - Physical & Chemical Properties Physical Properties: Additional Information The data provided in this section are to be used for product safety handling purposes. Please refer to Product Data Sheets, Certificates of Conformity or Certificates of Analysis for chemical and physical data for determinations of quality and for formulation purposes. Appearance: Lustrous white to grayish -white solid Odor: Odorless Physical State: Crystalline, granules or powder pH: 3.0 -4.0 (5% aqueous solution at 25 deg C) Vapor Pressure: Essentially 0 mm Hg Vapor Density: Not applicable Boiling Point: > 1600 deg C (2912 deg F) [anhydrous] Freezing/Melting Decomp at 770 deg C (1418 deg F) Point: Solubility (H20): 87.5 g /100mL at 20 deg C Specific Gravity: 1.95 at 4 deg C Refractive Index: 1.47 Particle Size: 149 -200 microns Softening Point: Not applicable Evaporation Rate: Not applicable Viscosity: Not applicable Bulk Density: 0.96 g /cc Percent Volatile: Not available Molecular Weight: 599.75 (342.14,Anhydrous) Chemical Formula: Al2(SO4)3.14.3H2O * * * Section 10 - Chemical Stability & Reactivity Information Chemical Stability Normally stable. In contact with water, sulfuric acid is formed with evolution of some amount of heat. When exposed to air, loss of combined water molecules by a hydrated material, such as this compound, will result in partial decomposition. Aluminum Sulfate is hydroscopic and will absorb moisture from the air. Chemical Stability: Conditions to Avoid Avoid contact with moisture, excessive heat and incompatible materials listed below. Incompatibility Aluminum Sulfate is incompatible with strong oxidizing agents and strong bases (may react violently), moisture and most common metals in presence of moisture. Hazardous Decomposition Thermal decomposition: Sulfur dioxide, sulfur trioxide, and aluminum oxide. In contact with water: sulfuric acid. Hazardous Polymerization Will not occur.
