Safety Information Sheet for Sulfuric Acid – Product Name, Hazard Warning Statements, Molecular Formula: Sulfuric Acid; Hazards: Highly corrosive and irritating. Chemical and physical properties: Melting point (°C): 10.5; Boiling point (°C): 330.0; Relative density (water = 1): 1.83. It is a colorless, transparent oily liquid. Contact with water releases large amounts of heat, which can cause boiling and splashing. Substances to be avoided: Bases, alkali metals, water, strong reducing agents, flammable or combustible materials. Products of combustion (decomposition): Sulfur oxides. Health hazards: In case of inhalation, it causes irritation of the respiratory tract, leading to breathing difficulties and pulmonary edema; high concentrations can cause laryngospasm or glottic edema, resulting in death from asphyxiation. Steam can cause conjunctivitis, conjunctival edema, and corneal opacity; if it gets into the eyes, it can cause burns, corneal perforations, panophthalmitis, and even blindness. Skin contact can cause burns; in mild cases, redness appears, while in severe cases ulcers and scars form. Inhalation: Quickly move to an area with fresh air and keep the airways unobstructed. If there is difficulty breathing, administer oxygen. If breathing stops, perform artificial respiration immediately and seek medical attention. Ingestion: Rinse mouth with water, give milk or egg white to drink, and seek medical attention. Eye contact: Immediately lift the eyelids and rinse thoroughly with plenty of flowing water or saline for at least 15 minutes, then seek medical attention. Skin contact: Immediately remove contaminated clothing and rinse with plenty of flowing water for at least 15 minutes; seek medical attention. Protection measures: 1. Respiratory protection: Wear a gas mask when exposed to sulfuric acid fumes; an air respirator must be used in emergency rescue situations. 2. Physical protection: Wear rubber acid-alkali resistant clothing. 3. Eye protection: Wear chemical safety goggles. 4. Hand protection: Wear rubber acid- and alkali-resistant gloves. Fire and explosion prevention measures for leak handling: 1. Evacuate the area quickly to a safe zone, isolate it, and establish a perimeter to strictly control access. 2. Emergency response personnel should wear air respirators and acid-alkali resistant protective clothing; they must not come into direct contact with the source of the leak, and should avoid entering confined spaces such as sewers and drainage ditches. 3. Minor leaks: Mix sand and dry lime, or rinse with plenty of water. Large-scale leakage: Build dikes or dig pits to contain it, or use pumps to transfer it to other containers.
