General Description
A clear colorless liquid with a pineapple-like odor. Flash point 78°F. Less dense than water and insoluble in water. Vapors heavier than air.
Hazards
Reactivity Alerts
Air & Water Reactions
Highly flammable. Insoluble in water.
Fire Hazard
Behavior in Fire: Vapor is heavier than air and may travel to a source of ignition and flash back. Containers may explode in fire. (USCG, 1999)
Health Hazard
Inhalation or ingestion causes headache, dizziness, nausea, vomiting, and narcosis. Contact with liquid irritates eyes. (USCG, 1999)
Reactivity Profile
ETHYL BUTYRATE is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. May attack some forms of plastics (USCG, 1999).
Belongs to the Following Reactive Group(s)
- Esters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters
Potentially Incompatible Absorbents

Response Recommendations
Isolation and Evacuation
Excerpt from 130
[Flammable Liquids (Water-Immiscible / Noxious)]:
IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 50 meters (150 feet) in all directions.
LARGE SPILL: Consider initial downwind evacuation for at least 300 meters (1000 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, 2020)
Firefighting
Excerpt from 130
[Flammable Liquids (Water-Immiscible / Noxious)]:
CAUTION: The majority of 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 regular foam.
LARGE FIRE: Water spray, fog or regular foam. Avoid aiming straight or solid streams directly onto the product. If it can be done safely, move undamaged containers away from the area around the fire.
FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: Fight fire from maximum distance or use unmanned master stream devices 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 master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2020)
Non-Fire Response
Excerpt from 130
[Flammable Liquids (Water-Immiscible / Noxious)]:
ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from 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. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. 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. (ERG, 2020)
Protective Clothing
All-purpose canister mask or chemical cartridge respirator; glass or face shield; rubber gloves (USCG, 1999)

First Aid
INHALATION: move victim to fresh air and call a physician; give artificial respiration if necessary.
INGESTION: induce vomiting and call a physician.
EYES: flush with water for at least 15 min.
SKIN: flush with water; wash with soap and water. (USCG, 1999)
