Hazardclass2.3
Hazard Narcotic in high concentrations. Flammable, explosive limits in air 12–28.5%.
Risk 11-20-36/37/38
Safety Poison by intraperitoneal route. Mildly toxic by inhalation. Narcotic in high concentration. An irritant. May liberate highly toxic hydrogen sulfide upon decomposition. A very dangerous fire hazard and moderate explosion hazard when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fire, stop flow of gas or use CO2, dry chemical, or water spray. When heated to decomposition it emits toxic fumes of CO. See also CARBONYLS and SULFIDES.
TOXIC; may be fatal if inhaled or absorbed through skin. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.
