Stability: Stability Extremely flammable. This material is a serious fire and explosion risk. Vapour may travel considerable distances to an ignition source, which need not be an open flame, but may be a hot plate, steam pipe, etc. Vapour may be ignited by the static electricty which can build up when isopropyl ether is being poured from one vessel

RIDADR: UN 1159 3/PG 2
WGK Germany: 1
RTECS: TZ5425000
F: 10
HazardClass: 3
PackingGroup: II
Moderately toxic by intraperitoneal route. Mildly toxic by ingestion, inhalation, and skin contact. A skin irritant. A very dangerous fire hazard and severe explosion hazard when exposed to heat, flame, sparks, or oxidizers. Under some conditions shock will explode it. Dangerous; on exposure to air it rapidly forms very sensitive, explosive peroxides that precipitate as crystals. Violent reaction with chlorosulfonic acid, HNO3. Potentially dangerous reaction with propionyl chloride can burst a sealed container. Reacts vigorously with oxidizing materials. To fight fire, use alcohol foam, CO2, foam, dry chemical. When heated to decomposition it emits acrid smoke and fumes. See also ETHERS.
