Safety Data Sheet for Ammonium Chloride

Ammonium Chloride Chemical Safety Data Sheet (MSDS) Part 1: Chemical Name Chinese name of the chemical: Ammonium Chloride English name of the chemical: Ammonium chloride Other Chinese names: None Other English names: None Data sheet identifier: Molecular formula: NH4Cl Molecular weight: Part 2: Composition/Information on ingredients Main ingredient: Pure substance CAS No.: 12125-02-9 Part 3: Hazard overview Hazard category: Route of exposure: Health hazards: This substance is irritating to the skin and mucous membranes; it can cause damage to liver and kidney function, lead to hepatic coma, as well as nitrogenemia and metabolic acidosis. In healthy individuals, 50 g of ammonium chloride can cause severe poisoning, while in patients with liver and kidney diseases as well as chronic heart disease, 5 g can already lead to serious poisoning. Oral poisoning causes chemical gastritis; in severe cases, a significant increase in blood ammonia levels can lead to hepatic coma. In severe poisoning, liver and kidney damage occurs, metabolic acidosis develops, along with a significant increase in bronchial secretions. Occupational exposure can cause irritation and burns to the respiratory mucosa. Chronic effects: Repeated exposure to ammonium chloride can cause chronic inflammation of the eye conjunctiva and respiratory mucosa. Environmental hazards: Flammability and explosion risk: Section 4: First aid measures. Skin contact: Remove contaminated clothing and rinse with plenty of flowing water. Eye contact: Lift the eyelids and rinse with flowing water or saline. Seek medical attention. Inhalation: Quickly move to a place with fresh air. Keep the airways clear. If there is difficulty breathing, administer oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention. Ingestion: Drink plenty of warm water and induce vomiting. Gastric lavage, catharsis. Seek medical attention. Part 5: Fire-fighting measures Hazardous properties: No special flammability or explosivity properties. It decomposes at high temperatures, producing toxic and corrosive fumes. Harmful combustion products: Extinguishing method: Firefighters must wear full-body fire and poison-resistant suits and extinguish the fire from the upwind side. When extinguishing a fire, move the container away from the fire site to an open area as much as possible. Precautions and measures for fire fighting: Section 6: Emergency response to leaks. Emergency handling: Isolate the area contaminated by the leak and restrict access. It is recommended that emergency responders wear dust masks (full-face masks) and protective clothing. Avoid dust; sweep carefully, place it in a bag, and transfer it to a safe location. In the event of a large spill, cover it with plastic sheeting or canvas. Collect and recycle, or transport to waste disposal sites for disposal. Part 7: Handling, Disposal, and Storage. Handling precautions: Storage precautions: Store in a cool, well-ventilated warehouse. Keep away from flames and heat sources. It should be stored separately from acids, bases, etc.; mixed storage is strictly prohibited. The storage area should be equipped with suitable materials to contain leaks. Part 8: Exposure Control/Personal Protection Maximum Allowable Concentration: China MAC: No standard established ； Former Soviet Union MAC:10 Monitoring method: Engineering controls: enclosed operation, comprehensive ventilation. Respiratory protection: When the dust concentration in the air exceeds the permissible level, a self-priming filter-type dust mask must be worn. An air respirator should be worn during emergency rescue or evacuation. Eye protection: Wear chemical safety goggles. Body protection: Wear work clothes resistant to toxic substance penetration. Hand protection: Wear rubber gloves. Other protections: Take a shower after work **. Pay attention to personal hygiene.

Polymerization hazards: Decomposition products: Part 11: Toxicological data Acute toxicity: LD50: 1650 mg/kg (oral, rats); LC50: No data Subacute and chronic toxicity: Irritation: Sensitization: Mutagenicity: Teratogenicity: Carcinogenicity: Other: Part 12: Ecological data Ecotoxicity: Biodegradability: Non-biodegradability: Bioaccumulation: Other harmful effects: Part 13: Disposal of waste Waste characteristics: Methods of disposal: The waste is pre-treated with sodium hydroxide solution; the ammonia released is recovered and reused. The remaining solution is diluted with water to the specified allowable concentration before being discharged into the wastewater system. Disposal precautions: Part XIV: Transport information. Hazardous goods identifier: No data available. UN number: No data available. Packaging mark: Packaging category: Z01. Packaging method: No data available. Transportation precautions: Part XV: Regulatory information. Domestic regulations on chemical safety management: the Regulations on the Safety Management of Chemical Hazardous Materials (issued by the State Council on February 17, 1987), the Detailed Rules for the Implementation of the Regulations on the Safety Management of Chemical Hazardous Materials (Document No. Hualao Fa 677), the Provisions on the Safe Use of Chemicals in the Workplace (Document No. Laobu Fa 423), and other regulations that set out rules regarding the safe use, production, storage, transportation, and handling of chemical hazardous materials.
