Satisfactory; may degrade after 4 hours continuous immersion <br />NATURAL+NEOPRENE......... Satisfactory; may degrade after 4 hours continuous immersion <br />NAT+NEOPR+NITRILE ......... Poor to dangerous choice for other than short-term immersion <br />Section 9 - Physical and Chemical Properties <br />Appearance/General Info: Hydrogen chloride: Colorless, corrosive gas. Pungent suffocating odor. White fumes in <br />moist air. Soluble in methanol, ethanol, ether and benzene. <br />Hydrochloric acid: Clear to light yellow (orange tint for inhibited grades) fuming corrosive liquid with sharp, <br />suffocating odor. <br />Physical State: Hydrogen chloride: Compressed gas; <br />Hydrochloric acid: Liquid <br />Odor Threshold: 0.26 to 0.3 ppm <br />Vapor Pressure (kPa): < 24.8 at 25 °C <br />Vapor Density (Air=1): 1.268 at 20 °C <br />Formula Weight: 36.461 <br />Specific Gravity (H2O=1, at 4 °C): < 1.19 at 20 °C <br />Evaporation Rate: Slow <br />pH: Hydrochloric acid: < 1 <br />Boiling Point: -85 °C (-121 °F) <br />Freezing/Melting Point: -114.44 °C (-173.992 °F) <br />Volatile Component (% Vol): 100 <br />Decomposition Temperature (°C): Not applicable <br />Water Solubility: 56.1 g/100 cc hot water at 60 °C <br />Section 10 - Stability and Reactivity <br />Stability/Polymerization/Conditions to Avoid: Decomposes in the presence of moisture to produce corrosive acid. <br />May generate sufficient heat to ignite combustible materials. Presence of heat source and direct sunlight (ultra-violet <br />radiation). Product is considered stable under normal handling conditions. Hazardous polymerization will not occur. <br />Storage Incompatibilities: Hydrogen chloride: Segregate from most common metals and their alloys, alkalis, <br />unsaturated organics, fluorine, metal carbides, metal acetylides, potassium permanganate and sulfuric acid. <br />Compatibility with plastics should be confirmed prior to use. <br /> Hydrochloric acid: Segregate from alkalies, oxidizing agents and chemicals readily decomposed by acids, i.e. <br />cyanides, sulfides, carbonates. Avoid storage with metals, metal oxides, hydroxides, amines, carbonates, alkaline <br />materials, acetic anhydride, cyanides, sulphides, sulphites, phosphides, acetylides, borides, carbides, silicides, vinyl <br />acetate, formaldehyde and potassium permanganate. Reacts with zinc, brass, galvanized iron, aluminum, copper and <br />copper alloys. <br />Section 11 - Toxicological Information <br />Toxicity <br />Inhalation (human) LCLo: 1300 ppm/30 m <br />Inhalation (human) LCLo: 3000 ppm/5 m <br />Inhalation (rat) LC50: 3124 ppm/60 m <br />Inhalation (rat) LC50: 4701 ppm/30 m <br />Oral (rat) LD50: 900 mg/kg <br />Irritation <br />Eye (rabbit): 5 mg/30 s - mild <br />See RTECS MW 4025000, for additional data. <br /> Section 12 - Ecological Information <br />Environmental Fate: No data found. <br />Ecotoxicity: TLm Gambusia affinis (mosquito fish) 282 ppm/96 hr (fresh water) /Conditions of bioassay not specified; <br />Lethal Lepomis macrochirus (bluegill sunfish) 3.6 mg/l/48 hr /Conditions of bioassay not specified; LC50 Cockle 330 <br />to 1,000 mg/l/48 hr /Conditions of bioassay not specified; LC50 Carassius auratus (goldfish) 178 mg/l (1 to 2 hr <br />survival time) /Conditions of bioassay not specified; LC50 Shore crab 240 mg/l/48 hr /Conditions of bioassay not <br />specified; LC50 Shrimp 100 to 330 ppm/48 hr (salt water) /Conditions of bioassay not specified; LC100 Trout 10 mg/l 24 <br />hr /Conditions of bioassay not specified <br />Biochemical Oxygen Demand (BOD): none <br />Section 13 - Disposal Considerations <br />Disposal: Recycle wherever possible. Consult manufacturer for recycling options. Treat and neutralize at an effluent <br />treatment plant. Bury residue in an authorized landfill. Decontaminate empty containers with a lime slurry. Return <br />empty containers to supplier or bury empty containers at an authorized landfill. <br /> Return empty cylinders to supplier.
