2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause central nervous system depression, characterized by excitement, followed by headache, dizziness, drowsiness and nausea. Advanced stages may cause collapse, unconciousness, coma and possible death due to respiratory failure. Eye
Excess redness and swelling of the conjunctiva may occur. Causes irritation, experienced as stinging and discomfort or pain. Skin
Brief contact is not irritating. Prolonged contact may cause more severe irritation, with discomfort or pain, local redness and swelling, and possible tissue destruction. Inhaled
Vapour causes irritation to the respiratory tract, with coughing and chest discomfort. Loss of consciousness, nausea and vomiting, weakness and incoordination may occur. High concentrations of vapour may cause headache and drowsiness. 2.2 Health Effects - Chronic
Breathing air which contains butyl acetate, resulting from its use in aerosol applications, may cause delayed lung damage. Skin contact may aggravate existing dermatitis.
2.3 First Aid
Swallowed
If patient is fully conscious, give two glasses of water. Induce vomiting. Seek medical attention.
Eye
Immediately flush eyes with water and continue washing for several minutes. Seek medical attention if discomfort persists.
Skin
Remove contaminated clothing. Wash skin with soap and water. Seek medical attention if irritation persists. Wash clothing before reuse.
Inhaled
Remove to fresh air. Give artificial respiration if not breathing. If breathing is difficult, oxygen may be given by qualified personnel. Seek medical attention.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
There is no specific antidote. Treatment of overexposure should be directed at the control of symptoms and the clinical condition of the patient. Individuals experiencing breathing difficulties after exposure to vapour generated in aerosol applications should be observed for at least 48 hours in case delayed respiratory complications occur.
2.6 Toxicity Data
Oral LD50 = 3200 mg/kg (Rabbit), 7060 mg/kg (Mouse), 10768 mg/kg (Rat) Dermal LD50 = > 20 mL/kg (Rabbit) Inhalation LC50 = 6 gm/m3/2hrs (Mouse), 2000ppm/4hrs (Rat)
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
TWA = 150 ppm (713 mg/m3) STEL = 200 ppm (950 mg/m3)
3.2 Engineering Controls
Ensure adequate ventilation to maintain exposure levels below standards.
3.3 Personal Protection
Wear self-contained breathing apparatus in high vapour concentrations. Wear butyl rubber gloves, monogoggles and other protective clothing to keep exposure to a minimum.

4.3 Spills and Disposal
Spills
Eliminate all sources of ignition - NO SMOKING. Evacuate area of personnel. Wear full protective clothing including self- contained breathing apparatus.
Disposal
Dispose of in accordance with all Local, State and Federal regulations at an approved waste disposal site. Incinerate in a furnace.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Material is incompatible with strong oxidising agents, nitric acid, sodium hydroxide, alkali metal hydroxides. Burning can produce carbon monoxide and/or carbon dioxide. Carbon monoxide is highly toxic if inhaled; carbon dioxide in sufficient concentrations can act as an asphyxiant. Hazardous polymerisation will not occur. Material is stable. Vapours from this product may travel or be moved by air currents and ignited by pilot lights, other flames, smoking, sparks, heaters, electrical equipment, static discharges or other ignition sources at locations distant from product handling point. This material may produce a floating fire hazard.
Extinguishing Media
Firefighters should wear full protective clothing including self-contained breathing apparatus. Use alcohol type or all-purpose type foams for large fires. Use carbon dioxide or dry chemical media for small fires. Use water spray to cool fire-exposed containers and structures. 5 OTHER INFORMATION
