密 度：2.103危險類別碼：R41危險品運輸編號：UN 2837安全說明：A corrosive irritant to skin, eyes, and mucous membranes. Mutation data reported. Reacts with moisture to form sulfuric acid. Mixtures with calcium hypochlorite + starch + sodium carbonate explode when compressed. Violent reaction with acetic anhydride + ethanol may lead to ignition and a vapor explosion. Incompatible with calcium hypochlorite. When heated to decomposition it emits toxic fumes of SOx and Na2O. See also SULFATES.包裝等級：II危險類別：8
儲存溫度：Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances. Keep away from water. Corrosives area.滅 火 劑：大量水
火警危險：Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.爆炸物危險特性：本身不能燃燒。受高熱分解放出有毒的氣體。具有腐蝕性。儲運特性：庫房通風低溫乾燥可燃性危險特性：不燃; 火場分解排出有毒硫氧化物和氧化鈉煙霧使用限量：GB 2760—2001：調製水，50mg/kg(以鈉計為13.7mg/kg)。健康危害：TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.鑑別試驗：按IT一29進行硫酸鹽鑑別試驗，呈陽性。含量分析：精確稱取試樣約5g，溶於約125ml水中，加酚酞試液(TS-167)數滴，用1mol/L氫氧化鈉滴定。每mL1mol/L氫氧化鈉相當於硫酸(H2SO4)49.04mg或硫酸氫鈉(NaHSO4)120.06mg。
