Hazards and Protection.
Keep containers tightly closed in a well ventilated area away from food products. Keep away from heat and water.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate clothing to prevent any reasonable probability of skin contact. Wear eye protection to prevent any possibility of eye contact.
Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive pressure mode. Any supplied-air respirator that has a full facepiece and is operated in pressure-demand or other positive pressure mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive pressure mode.
Make no contact with the spilled material. ELIMINATE all ignition sources and ground all equipment. Stop leak if you can do it without risk. 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.
Heat contributes to instability.
Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products Incompatible with the following: Nitrates; strong oxidizers, alkalis & acids.
When heated to decomposition it emits acrid smoke and irritating fumes.

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.
Very flammable. Flammable, moderate fire risk.
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers.
When heated emits acrid fumes.
TLV: 125 ppm; 665 mg/m3 (as TWA) (ACGIH 1993-1994). OSHA PEL: TWA 125 ppm (650 mg/m3) NIOSH REL: TWA 125 ppm (650 mg/m3) NIOSH IDLH: 1000 ppm
Headache, dizziness, fatigue, and narcosis may occur.
Nausea, vomiting, and diarrhea may occur.
Cough and rapid breathing may occur.
A drying of skin and irritation may occur.
Amyl acetate causes irritation of the eyes and mucous membranes.
Administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents. Consider inserting a nasogastric tube to aspirate gastric contents after recent large ingestions.
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
