Argon

Part I: Chemical Name Product Chinese Name: Argon Chemical Common name: English name of chemicals: argon English Title: Technical Manual Code: 104 CAS No .: 7440-37-1 Manufacturer Name: Address: Effective Date: second Part I: Composition / information harmful ingredients CAS No. argon ≥99.99% 7440-37-1 Part III: Dangerous category: pathways: health hazards: toxic under constant pressure. High concentration, oxygen pressure decreased and asphyxia. Argon concentration of more than 50%, causing severe symptoms; when more than 75%, may die within minutes. When the argon concentration in the air increases, first appeared breathing, inability to concentrate, ataxia. Followed, fatigue, irritability, nausea, vomiting, coma, convulsions, and even death. Liquid argon can cause skin frostbite; eye contact may cause inflammation. Environmental hazards: Explosion hazard: This product is flammable, asphyxiating. Part IV: After skin contact: If frostbite, medical care treatment. Eye contact: Did eyelid, with the flowing water or saline. Medical treatment. Inhalation: rapidly from the scene to fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, artificial respiration immediately. Medical treatment. Ingestion: Part V: Fire-fighting measures: In case of high fever, increased pressure within containers, cracking and the risk of explosion. Hazardous combustion products: fire fighting methods: This product is flammable. Cut off the gas source. Cooling water containers, if possible to move containers from the scene empty Department. Part VI: leakage Emergency treatment: rapid withdrawal of staff from air leakage supremacy wind and isolation and strict restrictions on access. Recommended emergency personnel wearing self-contained breathing apparatus, wearing overalls general operations. Cut off the source of leakage as possible. A reasonable ventilation, accelerated proliferation. If possible, ready to use. Leak containers should be properly handled, repair, testing later use. Part VII: HANDLING AND STORAGE Handling Precautions: closed operation. Closed operation, with good natural ventilation. The operator must go through specialized training, strict adherence to rules. Prevent gas leakage into the workplace air. Away from flammable and combustible materials. Handle with care disposal to prevent damaged cylinders and accessories. Equipped with spill response equipment. Storage: Store in a cool, ventilated warehouse. Away from fire and heat. Storage temperature should not exceed 30 ℃. It should be easy (to) fuel was stored separately and avoid mixing reservoir. Storage areas should be equipped with spill response equipment. Section 8: Exposure Control / Personal Protection China MAC (mg / m3): not established the former Soviet Union MAC (mg / m3): failure to develop standard TLVTN: ACGIH asphyxiating gas TLVWN: failure to develop standard monitoring methods: engineering controls: closed operation. Provide good natural ventilation. Respiratory protection: general need special protection. However, when the oxygen concentration in workplace air less than 18%, you must wear air respirators, oxygen respirator mask or long pipe. Eye protection: general need special protection. Physical protection: wear overalls general operations. Hand protection: Wear protective gloves general operations. Other protection: Avoid inhalation of high concentrations. Enter cans, or other restrictive space of high concentration operations, someone custody. Part IX: Physical and Chemical Properties Appearance: colorless, odorless inert gas. pH: Melting point (℃): -189.2 Relative density (water = 1): 1.40 (-186 ℃) Boiling point (℃): -185.7 Relative Vapor Density (Air = 1): 1.38 Molecular formula: Ar Molecular weight: 39.95 main components: content : high-purity ≥99.999%; pure argon ≥99.99%. Saturated vapor pressure (kPa): 202.64 (-179 ℃) heat of combustion (kJ / mol): meaningless Critical temperature (℃): -122.3 critical pressure (MPa): 4.86 of octanol / water partition coefficient: Not available Flash Point (℃): meaningless upper limit of explosion% (V / V): meaningless Ignition Temperature (℃): meaningless Explosive limit% (V / V): meaningless Solubility: soluble in water. Main purposes: for the pneumatic bulb and stainless steel, magnesium, aluminum, arc welding, the "welding." Other properties: Part 10: Stability and reactivity Stability: Incompatibility: Conditions to Avoid: Hazardous Polymerization: decomposition products: Section 11: Toxicological Information Acute toxicity: LD50: Not available LC50: None Information subacute and chronic toxicity: irritation: Sensitization: Mutagenicity: Teratogenicity: Carcinogenicity: Section 12: Ecological Information toxicological toxicity: biodegradable: non-biodegradable: Bioconcentration or bioaccumulation: Other harmful effects: environmentally friendly. Section 13: Disposal considerations: Waste disposal method: disposal of the national and local regulations. Exhaust gas directly into the atmosphere. Waste Note: Part 14: Transport Information Dangerous Goods Code: 22011 UN Number: 1006 Packing mark: Packaging Category: O53 Packing method: steel cylinders; ampoule outside the ordinary wooden box. Transportation Note: The cylinders must wear helmets on the bottle just transport. Cylinders generally flat, and the bottle in the same direction, can not cross; height shall not exceed the vehicle fence board, and with a triangular wooden pad cards firmly, to prevent rolling. With no flammable or combustible materials mixed mixed operation. Summer should be sooner or later transport to prevent sun exposure. Railway transportation to prohibit the slide release. Section 15: REGULATORY INFORMATION Chemical Dangerous Goods Safety Management Regulations (February 17, 1987 the State Council), the Regulations of Hazardous Chemical Safety Management Regulations (the Labor Fa [1992] No. 677), the workplace safe use of chemical product ([1996] labor department No. 423) and other regulations, the safe use of hazardous chemicals, production, storage, transport, handling, etc. are made corresponding provisions; commonly used classification of dangerous chemicals and signs (GB 13690- 92) the substance is classified as non-combustible gases Class 2.2.
