Physical and Chemical Properties
CAS Number: 7439-90-9.
Physical and Chemical Characteristics: Colorless and odorless inert gas. Insoluble in water and ethanol. Melting point (℃): -156.6; Boiling point (℃): -151.7; Relative density (water=1): No data; Relative density (air=1): 2.92; Saturation vapor pressure (kPa): No data; Flash point (℃): Not applicable; Combustion heat (kJ/mol): Not applicable; Critical temperature (℃): No data; Critical pressure (MPa): No data; Upper and Lower Explosion Limits (v%): Not applicable; Ignition temperature (℃): Not applicable.
Combustion and Explosion Hazards: Non-flammable. Under high heat, the pressure inside the container may increase, posing a risk of rupture and explosion.
Firefighting Methods: Non-flammable. Remove containers from the fire area if possible. Spray water to keep the containers cool until the fire is out. Evacuate people to the upwind side and isolate the contaminated area. Emergency personnel should wear self-contained positive pressure breathing apparatus and general work clothes. Cut off the leak source if possible. Ensure adequate ventilation to disperse the gas. Handle the leaking container properly, repair and inspect before reuse.
Health Hazards: Inert gas, high concentrations can reduce oxygen partial pressure and pose a risk of asphyxiation. Symptoms include increased breathing rate, lack of concentration, ataxia, followed by fatigue, restlessness, nausea, vomiting, coma, convulsions, and potentially death.
First Aid Measures: Inhalation: Quickly move to a fresh air area. Keep the airway clear. If breathing is difficult, administer oxygen. If breathing stops, perform artificial respiration immediately. If breathing and heartbeat stop, perform artificial respiration and external chest compressions immediately.
