丨Shandong Province Hazardous Chemicals Registration Material Safety Data Sheet Chemical Name: Hydrochloric acid unit name: Unit address: emergency phone: Part 1 Chemicals and Corporate Identification Chemical Names in Chinese: Trade name or common name of hydrochloric acid chemicals: English name of hydrochloric acid chemicals: Hydrocnloric acid chlorohy dric acrd company name: address: post code: email address: Fax number: Enterprise emergency hotline: Technical specification code: 043 Effective date: July 1, 2003 * * emergency phone: Part 2 Ingredient/Composition Information Pure product □ Mixture √ Chemical name: Concentration of harmful components of hydrochloric acid CAS No. HCl ≥31% 7647-01-0 Part 3 Hazard Summary Hazard Category: Category 8.1 Intrusion routes of acidic corrosives: Health hazards of inhalation and ingestion: Contact with its vapor or smoke can cause conjunctivitis, burning sensation in the mucosa of the nose and mouth, epistaxis, gum bleeding, and tracheitis. ； Stimulates the skin and causes dermatitis, chronic bronchitis and other diseases. Poisoning by accidental ingestion of hydrochloric acid can cause gastrointestinal burns, ulcer formation, and possible gastric perforation, peritonitis, etc. environmental hazards: Corrosiveness, attention, pollution to the environment. Fire and explosion hazard: No information available Section 4 First aid measures Skin contact: Rinse immediately with water for at least 15 minutes. Or rinse with 2% sodium bicarbonate solution. If burns occur, seek medical attention. eye contact: Immediately lift the eyelids and rinse with running water for 10 minutes or with 2% sodium bicarbonate solution. inhalation: Leave the scene quickly and get to fresh air. Give oxygen if breathing is difficult. Give 2-4% sodium bicarbonate solution for aerosol inhalation. Seek medical attention. ingest: If you swallow it by mistake, rinse your mouth immediately and give milk, egg white, vegetable oil, etc. orally. Do not induce vomiting. Get medical attention immediately. Part 5: Hazardous Characteristics of Fire Fighting Measures: Can react with some active metal powders to release hydrogen. In contact with cyanide, highly toxic hydrogen cyanide gas can be produced. Neutralization reaction occurs with alkali and releases a lot of heat. It is highly corrosive. Hazardous combustion products: Hydrogen chloride fire extinguishing methods and fire extinguishing agents: Precautions for fire extinguishing with mist water and sand: Unrelated personnel are prohibited from entering the contaminated area, and emergency responders are advised to wear gas masks and chemical protective suits. Part 6 Emergency Response to Leakage Emergency Response: Handlers wear gas masks and chemical protective suits. Elimination method: It can be rinsed with plenty of water, and the diluted wash water can be put into the wastewater system. If there is a large amount of leakage, use dikes to contain it, then collect, transfer, recycle or dispose of it after harmless treatment. Part 7 Handling and Storage Precautions: When handling, load and unload with care to prevent damage to packaging and containers. Storage precautions: Store in a cool, dry and ventilated place. It should be stored separately from alkali, metal powder, halogen, flammable and combustible materials, etc. Part 8 Exposure Control/Personal Protection Maximum Allowable Concentration: No data monitoring method: Chemical Titration Engineering Control: Close operation and pay attention to ventilation. Mechanize and automate as much as possible. respiratory protection: A gas mask or air-supplied helmet must be worn when coming into contact with its vapors or fumes. eye protection: Wear chemical safety glasses. body protection: Wear work clothes and hand protection: Wear rubber gloves and other protection: After work, take a shower * * . Store poison-contaminated clothing separately and launder before use. maintain good hygiene * used. Part 9 Physical and Chemical Properties Appearance and Properties: Colorless or slightly yellow fuming liquid with a pungent sour smell. pH value: 1 Melting point (℃): -114.8 (pure) relative density (water = 1): 1.20 Boiling point (℃): 108.6(20%) relative vapor density (air=1): 1.26 Saturated vapor pressure (kPa): 30.66/21℃ Heat of combustion (kj/mol): No data critical temperature (℃): No data critical pressure (MPa): No data available Log value of octanol/water partition coefficient: No data available Flash point (℃): Meaningless explosion upper limit % (V/V): Meaningless ignition temperature (°C): Meaningless explosion lower limit % (V/V): meaningless solubility: Miscible with water, soluble in alkali solution Main uses: Important inorganic chemical raw materials, widely used in dye, medicine, food, printing and dyeing, leather, metallurgy and other industries. Other physical and chemical properties: Colorless or slightly yellow fuming liquid with a pungent sour smell. Part 10 Stability and Reactivity Stability: Stable incompatible substances: Alkalis, amines, alkali metals, flammable or combustible substances. Conditions to avoid contact: Polymerization hazards from exposure to moist air: No decomposition products should appear: Hydrogen Chloride Part 11 Toxicological Information Acute Toxicity: No data available Subacute and chronic toxicity: Causes conjunctivitis and burning sensation in nasal or oral mucosa. irritating: Stimulate the skin, cause dermatitis, chronic bronchitis and other diseases. Sensitization: Epistaxis, gum bleeding, tracheitis mutagenicity: It can cause gastrointestinal burns, ulcer formation, gastric perforation, peritonitis, etc. Teratogenicity: No data on carcinogenicity: No information available Part 12 Ecological information Ecotoxicity: No data available Biodegradability: No data availableNon-biodegradability: No data on bioconcentration or bioaccumulation: No information available Part 13 Waste disposal Nature of waste: √Hazardous waste □Industrial solid waste disposal methods: Neutralize with alkaline. When there is a large amount of leakage, use a dike to collect it and mix it with lime. Disposal precautions: Reduce the scope of contamination and pay attention to burns. Part 14 Transport information. Dangerous goods number.: 81013 UN number: 1789 packaging mark: 20 packaging categories: Class II packaging method: Precautions for transporting fiberglass tanks by tank truck: When transporting, load and unload with care to prevent damage to packaging and containers. It is not suitable to transport on rainy days.
