Hazards and Protection.
Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area.
Wash thoroughly after handling. Use spark-proof tools and explosion proof equipment. Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Avoid contact with heat, sparks and flame. Use only in a chemical fume hood. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Wash area with soap and water. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation.
Stable under normal temperatures and pressures.
Oxidizing agents, strong acids, strong bases, amines, nitrates.
Carbon monoxide, carbon dioxide, acrid smoke and fumes.

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Use foam, dry chemical, or carbon dioxide. Water may be ineffective.
Flammable liquid and vapor.
Flashback along vapor trail may occur.
Toxic vapors and gases (such as carbon monoxide) may be released in a fire involving sec-butyl acetate.
TLV (as TWA): 200 ppm; 950 mg/m3 (ACGIH 1995-1996). OSHA PEL: TWA 200 ppm (950 mg/m3) NIOSH REL: TWA 200 ppm (950 mg/m3) NIOSH IDLH: 1700 ppm LEL
Chronic inhalation may cause effects similar to those of acute inhalation.
May cause irritation of the digestive tract.
Causes respiratory tract irritation. Exposure produces central nervous system depression. Vapor or mist is irritating to the mucous membranes and upper respiratory tract.
Causes skin irritation. Prolonged and/or repeated contact may cause irritation and/or dermatitis.
Vapors cause eye irritation.
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 immediately.
Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.
