Vapors are heavier than air. Prolonged exposure to low concentrations or short exposure to high concentrations may have adverse health effects from inhalation.
  CAMEO Chemicals
• Allyl alcohol is a propenol in which the C=C bond connects C-2 and C-3. It is has been found in garlic (Allium sativum). Formerly used as a herbicide for the control of various grass and weed seeds. It has a role as a fungicide, a herbicide, an insecticide, an antibacterial agent and a plant metabolite. It is a primary allylic alcohol and a propenol.

6Accidental release measures

Isolation and evacuation

• Excerpt from ERG Guide 131 [Flammable Liquids - Toxic]: IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions. SPILL: See ERG Table 1 - Initial Isolation and Protective Action Distances on the UN/NA 1098 datasheet. FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)
  CAMEO Chemicals
• Immediate precautionary measure · Isolate spill or leak area for at least 50 meters (150 feet) in all directions. Spill · For highlighted materials: see Table 1 - Initial Isolation and Protective Action Distances. · For non-highlighted materials: increase the immediate precautionary measure distance, in the downwind direction, as necessary. Fire · If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.
  Emergency Response Guidebook (ERG)

Spill cleanup

• Remove all ignition sources. Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable air tight containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.
  ILO-WHO International Chemical Safety Cards (ICSCs)
• Releases may require isolation or evacuation. Stop or control the leak, if this can be done without undue risk. Use water spray to cool and disperse vapors, protect personnel, and dilute spills to form nonflammable mixtures. Approach release from upwind. Eliminate all ignition sources. Control runoff and isolate discharged material for proper disposal.
  Hazardous Substances Data Bank (HSDB)
• If allyl alcohol is spilled or leaked, the following steps should be taken: remove all ignition sources, ventilate area of spill or leak, and for small quantities absorb on paper towels. Evaporate in a safe place, such as a fume hood. Allow sufficient time for evaporating vapors to completely clear the hood ductwork. Burn the paper in a suitable location away from combustible materials. Large quantities can be collected and atomized in a suitable combustible chamber. Allyl alcohol should not be allowed to enter a confined space, such as a sewer, because of the possibility of an explosion.
  Hazardous Substances Data Bank (HSDB)
• Environmental considerations: Land spill: Dig a pit, pond, lagoon, or holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquids with fly ash, cement powder, or commercial sorbents. Apply "universal" gelling agent to immobilize spill.

9Physical and chemical properties

10Stability and reactivity

Reactivity

• ALLYL ALCOHOL presents a dangerous fire and explosion hazard when exposed to heat, flame, or oxidizing agents. Reacts violently or explosively with sulfuric acid, strong bases. Reacts violently with 2,4,6-trichloro-1,3,5-triazine and 2,4,6-tris(bromoamino)-1,3,5-triazine. Reacts with carbon tetrachloride to produce explosively unstable products [Lewis]. Mixing allyl alcohol in equal molar portions with any of the following substances in a closed container caused the temperature and pressure to increase: chlorosulfonic acid, nitric acid, oleum, sulfuric acid [NFPA 491M. 1991].
  CAMEO Chemicals
• Highly flammable. Water soluble.

Incompatible materials and hazardous reactions

• Incompatible materials: Alkali metals, Oxidizing agents
  Hazardous Substances Data Bank (HSDB)
• A reaction between allyl alcohol and carbon tetrachloride produced trichlorobutylene epoxide (oxide) and dichlorobutylene epoxide (oxide), a mixture which during distillation proved to be unstable and detonated in the still.
  Hazardous Substances Data Bank (HSDB)
• When aqueous sodium hydroxide was added to a mixture of /2,4,6-trichlorotriazine/ and /allyl/ alcohol at 28 °C instead of the normal 5 °C, a rapidly accelerating reaction led to the rupture of the bursting disc and a gasket, and subsequently to a flash fire and explosion.

12Ecological information

Environmental fate

• Allyl alcohol's production and use as an intermediate in the production of glycerol, diallyl phthalate, diallyl isophthalate (monomer and prepolymer), acrolein, epichlorhydrin, pharmaceuticals and other chemicals may result in its release to the environment through various waste streams. Allyl alcohol is reported in the bulb and essential oil of garlic. If released to air, a vapor pressure of 25.4 mm Hg at 25 °C indicates allyl alcohol will exist solely as a vapor in the atmosphere. Vapor-phase allyl alcohol will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals, ozone and night-time nitrate radicals;
