Sixth, hydrogen and argon mixed gas application
Chemical and corporate identity
Chinese name: argon, hydrogen mixed gas (reduced welding mixed gas type)
English name: Mixed Gases Of Argon and Hydrogen
Molecular formula: H2-Ar
Molecular weight: 2.016-39.948
Chemical category: Compressed gas (Hz flammable, Ar-non-combustible)
Composition/composition information
Ingredients: hydrogen content (v / v) 1. 15 × 10-2, the remaining argon.
Main use: Metal welding for reducing atmosphere.
Seven, matters needing attention
Hazard class: hydrogen - Class 2.1 flammable compressed gas, flammable and explosive; Argon - Class 2.2 non-combustible compressed gas, asphyxiating. Route of entry: inhalation.
Health hazards: Both hydrogen and argon are non-toxic, but they have a suffocating effect at high concentrations. When the concentration of argon in the air is higher than 33%, there is a danger of suffocation; when the concentration of argon exceeds 50%, severe symptoms occur; when the concentration is above 75%, it can die within a few minutes. There are few instances of daily death due to hydrogen suffocation, but fires and explosions caused by hydrogen continue to occur. The symptoms of suffocation are as follows: initial breathing increases, muscle movement disorders, and then all loss of feeling, body fatigue, and then nausea, vomiting, loss of consciousness, paralysis, lethargy, resulting in death.
first-aid
Inhalation: Remove quickly from the scene to fresh air. If breathing stops, perform artificial respiration immediately. Seek medical attention.
Fire-fighting measures
Flammability: Hydrogen has a wide flammable range in air and oxygen (combustible range in air: 4.0~74.5%; flammable range in oxygen: 4~94%), hydrogen is extremely flammable, in the form of heat release or explosion A lot of energy is released.
Lower explosion limit (%): 4.0 (hydrogen in air or oxygen)
Ignition temperature (°C): The lowest ignition point of hydrogen is 560~570.
Upper explosion limit (%): hydrogen is 74.5 in air: 94 in oxygen.
Minimum ignition energy (mJ): meaningless '
Hazardous characteristics: When the cylinder pressure is too high, or the cylinder is subjected to severe vibration and shock, or the cylinder is strongly heated, the cylinder may be in danger of explosion. Hydrogen is extremely flammable, releasing a large amount of energy in an exothermic or explosive manner, and hydrogen is flammable and explosive.
Extinguishing method: The most effective way to extinguish a hydrogen flame is to cut off the gas source. You can use powder fire extinguishing agent, water spray, carbon dioxide, l211 fire extinguishing agent, l301 fire extinguishing agent, etc., to have a safe distance when extinguishing fire, and to stand in the upwind direction, the gas container in the flame should be watered to cool to prevent temperature explosion. .
Leakage emergency treatment
Hydrogen has the smallest molecules and is very easy to leak. When the hydrogen leaks, first cut off all the fire sources, then plugging and exhausting. Waste hydrogen can be discharged into the open atmosphere, but care must be taken to ensure the safety of the surrounding environment.
Handling and storage
Store in a cool, ventilated warehouse. The temperature in the warehouse should not exceed 40 °C. Keep away from fire and heat. Protect from direct sunlight. It should be stored strictly separate from oxidants such as flammable materials, metal powders and oxygen. Pay attention to the name of the product during the acceptance, pay attention to the date of the bottle inspection, and the first use of the advanced warehouse. Lightly load and unload during handling to prevent damage to cylinders and accessories. Do not score. Cylinder valve operation must use a standard handwheel.
