NFPA 704

Diamond Hazard Value Description 4 4 4 Health 4 Can be lethal. Flammability 4 Burns readily. Rapidly or completely vaporizes at atmospheric pressure and normal ambient temperature. Instability 4 Readily capable of detonation or explosive decomposition or explosive reaction at normal temperatures and pressures. Special (NFPA, 2010)

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

Explosive

Strong Oxidizing Agent

Pyrophoric

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

Isolation and Evacuation





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



SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above.



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) Excerpt from ERG Guide 131 [Flammable Liquids - Toxic]:As an immediate precautionary measure, isolate spill or leak area for at least 50 meters (150 feet) in all directions.SPILL: Increase, in the downwind direction, as necessary, the isolation distance shown above.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.

Firefighting





CAUTION: All these products have a very low flash point: Use of water spray when fighting fire may be inefficient.



SMALL FIRE: Dry chemical, CO2, water spray or alcohol-resistant foam.



LARGE FIRE: Water spray, fog or alcohol-resistant foam. Move containers from fire area if you can do it without risk. Dike fire-control water for later disposal; do not scatter the material. Use water spray or fog; do not use straight streams.



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. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. 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.

Non-Fire Response





Fully encapsulating, vapor-protective clothing should be worn for spills and leaks with no fire. ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if you can do it without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor-suppressing foam may be used to reduce vapors.



SMALL SPILL: Absorb with earth, sand or other non-combustible material and transfer to containers for later disposal. Use clean, non-sparking tools to collect absorbed material.



LARGE SPILL: Dike far ahead of liquid spill for later disposal. Water spray may reduce vapor, but may not prevent ignition in closed spaces.
