NFPA 704:
  • Red 4 -- Flammability: Extremely flammable
  • Blue 4 -- Health Hazard: Too dangerous to enter - vapor or liquid
  • Yellow 4 -- Reactivity: May detonate - evacuate area if materials are exposed
General Description
A clear colorless to yellow liquid with a pleasant odor. Flammable over a wide range of vapor-air concentrations. Flash point -31°F. Less dense than water and insoluble in water. Vapors are heavier than air and narcotic in high concentrations. Produces toxic oxides of nitrogen during combustion.

Hazards

Reactivity Alerts
Air & Water Reactions
Highly flammable. Vapors may ignite spontaneously and the reaction may reach explosive violence. Insoluble in water. Decomposes in water.
Fire Hazard
Special Hazards of Combustion Products: Toxic oxides of nitrogen are generated.

Behavior in Fire: Vapors are heavier than air and may travel a considerable distance to a source of ignition and flash back; can decompose violently above 194°F; containers may explode in a fire. (USCG, 1999)
Health Hazard
Inhalation or ingestion causes headache, increased pulse rate, decreased blood pressure, and unconsciousness. Contact with liquid irritates eyes and skin. (USCG, 1999)
Reactivity Profile
ETHYL NITRITE is a powerful oxidizing agent. Highly dangerous in contact with acid or acid fumes. Dangerous when heated. Decomposes spontaneously at 194°F. Decomposed by light.
Belongs to the Following Reactive Group(s)

Response Recommendations

Firefighting
Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may spread fire. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide. (AAR, 2003)
Non-Fire Response
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors. Land Spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk liquid with fly ash, cement powder, or commercial sorbents. Water Spill: Use natural barriers or oil spill control booms to limit spill travel. Remove trapped material with suction hoses. (AAR, 2003)
Protective Clothing
Self-contained breathing apparatus; goggles or face shield; rubber gloves. (USCG, 1999)
First Aid
INHALATION: remove victim from exposure; if breathing has stopped, give artificial respiration; call physician.

EYES: flush with water for at least 15 min.; get medical attention if irritation persists.

SKIN: flush with water, wash with soap and water.

INGESTION: do NOT induce vomiting; call physician. (USCG, 1999)
