General Description
Colorless to yellow watery liquid with a weak odor of bananas. Floats on water. Produces irritating vapor. (USCG, 1999)

Hazards

Reactivity Alerts
Air & Water Reactions
Highly flammable.
Fire Hazard
Special Hazards of Combustion Products: When heated emits acrid fumes.

Behavior in Fire: When exposed to flames can react vigorously with oxidizing material. (USCG, 1999)
Health Hazard
INHALATION AND INGESTION: Irritates the mucous membrane, depresses the central nervous system and is narcotic. Damage to kidney, liver, and lung can occur. Ingestion may irritate gastro-intestinal tract. EYES: Irritation. SKIN: Irritation. (USCG, 1999)
Reactivity Profile
TERT-AMYL ACETATE 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.
Belongs to the Following Reactive Group(s)

Response Recommendations

Isolation and Evacuation
Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / 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 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)
Firefighting
Fire Extinguishing Agents Not to Be Used: Water may be ineffective.

Fire Extinguishing Agents: Water fog in conjuction with alcohol foam, dry chemical or carbon dioxide. (USCG, 1999)
Non-Fire Response
Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / 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, 2024)
Protective Clothing
Rubber gloves, chemical goggles or face shield, and lab coat. Organic vapor chemical cartridge respirator for less than 1000 ppm; self-contained breathing apparatus for greater than 1000 ppm. (USCG, 1999)
DuPont Tychem® Suit Fabrics

First Aid
Call a physician.

INHALATION: Remove from exposure. Administer oxygen if needed.

EYES: Flush with water for at least 15 min.

SKIN: Remove contaminated clothing and shoes. Wash with soap and water. Subsequent treatment is symptomatic and supportive in nature. (USCG, 1999)
