Safety Information
CAS Number: 1333-74-0.
Physical and Chemical Properties: Colorless and odorless gas. Insoluble in water, ethanol, and ether. Melting point (℃): -259.2; Boiling point (℃): -252.8; Relative density (water=1): 1.20 (-246℃); Relative density (air=1): 0.7; Saturation vapor pressure (kPa): 101.32 (-246℃); Flash point (℃): Not applicable; Combustion heat (kJ/mol): Not applicable; Critical temperature (℃): -228.7; Critical pressure (MPa): 2.73; Upper explosion limit (v%): Not applicable; Lower explosion limit (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: Flammable, forms explosive mixtures with air. Can explode when exposed to heat or open flame. Lighter than air, leaks can rise and linger in indoor spaces, posing an explosion risk if ignited. Reacts violently with halogens such as fluorine, chlorine, and bromine. Cut off the gas supply. Do not extinguish the fire if the gas supply cannot be cut off. Firefighters must wear air呼吸器 (respirators) and full protective clothing, and fight the fire from the upwind direction. Remove containers from the fire area if possible. Cool the containers with water until the fire is out. Fire extinguishing agents: water spray, foam, carbon dioxide, dry powder.
Health Hazards: Physiologically inert gas, can cause asphyxiation at high concentrations due to reduced oxygen partial pressure. Can exhibit anesthetic effects at very high pressures. Symptoms of oxygen deprivation include palpitations, shortness of breath, dizziness, headache, weakness, vertigo, nausea, vomiting, tinnitus, blurred vision, and impaired judgment. Severe cases can quickly progress to mental confusion, loss of consciousness, and potentially respiratory and circulatory failure.
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.
