CAS# Chemical Name Percent EINECS/ELINCS
628-63-7 Amyl acetate 100 211-047-3

Section 3 - Hazards Identification


Appearance: colorless liquid. Flash Point: 23 deg C.
Warning! Flammable liquid and vapor. Causes eye irritation. May cause skin irritation. May cause central nervous system depression. May cause liver damage. May cause cardiac disturbances.
Target Organs: Heart, central nervous system, liver.

Potential Health Effects
Eye: Causes eye irritation.
Skin: May cause skin irritation. May be absorbed through the skin. Repeated or prolonged exposure may cause drying and cracking of the skin.
Ingestion: May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause effects similar to those for inhalation exposure. Ingestion of large amounts may cause CNS depression.
Inhalation: Inhalation of high concentrations may cause central nervous system effects characterized by nausea, headache, dizziness, unconsciousness and coma. May cause liver abnormalities. Aspiration may lead to pulmonary edema. Vapors may cause dizziness or suffocation. May cause cardiac abnormalities. Causes irritation of the mucous membrane and upper respiratory tract. May cause burning sensation in the chest.
Chronic: Prolonged or repeated skin contact may cause dermatitis. Chronic exposure may cause liver damage. Chronic exposure will cause neurological degradation and/or abnormalities.

Section 4 - First Aid Measures

Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Ingestion: Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid.
Inhalation: Get medical aid immediately. Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Notes to Physician: Treat symptomatically and supportively.

Section 5 - Fire Fighting Measures

General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Water runoff can cause environmental damage. Dike and collect water used to fight fire. Vapors may form an explosive mixture with air. Vapors can travel to a source of ignition and flash back. Combustion generates toxic fumes. Will burn if involved in a fire. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. Flammable liquid and vapor.
Extinguishing Media: For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam. For large fires, use water spray, fog, or alcohol-resistant foam. Use water spray to cool fire-exposed containers. Water may be ineffective. Do NOT use straight streams of water.
Flash Point: 23 deg C ( 73.40 deg F)
Autoignition Temperature: 360 deg C ( 680.00 deg F)
Explosion Limits, Lower:1.1 vol %
Upper: 7.5 vol %
NFPA Rating: (estimated) Health: 1; Flammability: 3; Instability: 0

Section 6 - Accidental Release Measures

General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation. A vapor suppressing foam may be used to reduce vapors.

Section 7 - Handling and Storage

Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well-ventilated area. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Avoid contact with skin and eyes. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep away from heat, sparks and flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Storage: Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area.

Section 8 - Exposure Controls, Personal Protection

Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.

Section 12 - Ecological Information

Ecotoxicity: Fish: Bluegill/Sunfish: LC50 = 650 mg/L; 96 Hr; Static bioassay at 23CFish: Mosquito Fish: LC50 = 65 mg/L; 24-96 Hr; Unspecified If released on land or in water, volatilization would be important (half-life 5.9 hr in a typical river) and biodegradation, should be a dominant degradative process. Adsorption to soil or sediment would not occur to any significant extent, so leaching into groundwater may occur. Some chemical hydrolysis may occur but only under fairly alkaline conditions. n-Amyl acetate would not be expected to bioconcentrate in aquatic organism.
Environmental: In air, n-amyl acetate will be scavenged by rain and degrade by reaction with photochemically produced hydroxyl radicals estimated half-life 4.5 days).
