General Description
A clear colorless liquid with an ether-like odor. Flash point 118°F. About the same density as water and insoluble in water. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion. Used as an additive for diesel fuels.

Hazards

Reactivity Alerts
Air & Water Reactions
Flammable. Insoluble in water.
Fire Hazard
Special Hazards of Combustion Products: Toxic oxides of nitrogen may form in a fire.

Behavior in Fire: Overheated material may detonate. (USCG, 1999)
Health Hazard
Inhalation or ingestion may cause headache, methemoglobin, and nausea. Liquid and vapor irritate eyes. Contact with skin may cause slight irritation. (USCG, 1999)
Reactivity Profile
AMYL NITRATE is an oxidizing reagent. When exposed to heat or flame it may decompose to form nitrogen oxides. Accelerates the burning of combustible materials. Can produce a violent reaction with reducing materials [Sax, 9th ed., p. 228].
Belongs to the Following Reactive Group(s)
Potentially Incompatible Absorbents

Use caution: Liquids with this reactive group classification have been known to react with the absorbents listed below.

Response Recommendations

Isolation and Evacuation
Excerpt from ERG Guide 140 [Oxidizers]:

As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.

LARGE SPILL: Consider initial downwind evacuation for at least 100 meters (330 feet).

FIRE: If tank, rail car or tank truck 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, 2016)
Firefighting
Excerpt from ERG Guide 140 [Oxidizers]:

SMALL FIRE: Use water. Do not use dry chemicals or foams. CO2 or Halon® may provide limited control.

LARGE FIRE: Flood fire area with water from a distance. Do not move cargo or vehicle if cargo has been exposed to heat. Move containers from fire area if you can do it without risk.

FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2016)
Non-Fire Response
Excerpt from ERG Guide 140 [Oxidizers]:

Keep combustibles (wood, paper, oil, etc.) away from spilled material. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Do not get water inside containers.

SMALL DRY SPILL: With clean shovel, place material into clean, dry container and cover loosely; move containers from spill area.

SMALL LIQUID SPILL: Use a non-combustible material like vermiculite or sand to soak up the product and place into a container for later disposal.

LARGE SPILL: Dike far ahead of liquid spill for later disposal. Following product recovery, flush area with water. (ERG, 2016)
