2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
Minimal toxicity. Small amounts of liquid aspirated into the respiratory system during ingestion or from vomiting may cause bronchopneumonia or pulmonary edema. Eye
Irritating and will injure eye tissue if not removed promptly. Skin
Frequent or prolonged contact may defat and dry skin, leading to discomfort and dermatitis. Low order of toxicity. Inhaled
Vapour concentrations above recommended exposure levels may be irritating to the eyes and the respiratory tract, may cause headaches and dizziness, could be anesthetic and may have other central nervous system effects. 2.2 Health Effects - Chronic
No data available
2.3 First Aid
Swallowed
First aid is not normally required.
Eye
Immediately flush eyes with large amounts of water for at least 15 minutes. Seek prompt medical attention.
Skin
Immediately flush with large amounts of water; use soap if available. Remove contaminated clothing, including shoes, after flushing has begun.
Inhaled
Using proper respiratory protection, immediately remove the affected victim from exposure. Administer artificial respiration if breathing has stopped. Keep at rest. Call for prompt medical attention.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
Treat symptomatically based on judgement of doctor and individual reactions of patient.
2.6 Toxicity Data
Oral LD50 = 5800 mg/kg (Rat) Dermal LD50 = 20,000 mg/kg (Rabbit) Inhalation LC50 = 50,100 mg/m3/8hrs (Rat)
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
TWA = 500 ppm (1,185 mg/m3) Worksafe STEL = 1,000 ppm (2,375 mg/m3) Worksafe
3.2 Engineering Controls
Ensure adequate ventilation to maintain levels below exposure standards.
3.3 Personal Protection
For open systems where contact is likely, wear long sleeves, chemical resistant gloves and chemical goggles. Where contact may occur, wear safety glasses with side shields. Where concentrations in air may exceed the exposure limits given and engineering, work practice or other means of exposure reduction are not adequate, approved respirators may be necessary to prevent overexposure by inhalation.
3.4 Flammability
Material is extremely flammable. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Store and transport in accordance with all applicable regulations for Class 3 liquids. Keep container closed. Open slowly in order to control possible pressure release. Store in a cool, well-ventilated area away from incompatible materials. Protect material from direct sunlight.
4.2 Packaging / Labelling UN No. 1090 Class 3 Sun Risk None Allocated Hazchem Code 2[Y]E Pack Group II EPG No. 3A1 Shipping Name ACETONE Hazard
Risk Phrases R11 Highly flammable.
Safety Phrases S9 Keep container in a well ventilated place. S16 Keep away from sources of ignition. S23:ACETON Do not breathe fumes/vapour. S33 Take precautionary measures against static discharges.
4.3 Spills and Disposal
Spills
Remove all sources of ignition - NO SMOKING.
Disposal
Dispose of in accordance with all Local, State and Federal regulations at an approved waste disposal facility.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Extreme hazard. Leaks of gas or spills of liquid can readily form flammable mixtures at temperatures at or above the flash point. Avoid contact with caustics, amines, alkanolamines, aldehydes, ammonia, strong oxidising agents, and chlorinated compounds. Incompatible materials and coatings include natural rubber, amine epoxy coatings, vinyl coatings, neoprene rubber, Buna N, PVC.
Extinguishing Media
Use water spray to cool fire exposed surfaces and to protect personnel. Shut off "fuel" to fire. If a leak or spill has not ignited, use water spray to disperse the vapours and to protect men attempting to stop a leak. Either allow fire to burn under controlled conditions or extinguish with alcohol type foam or dry chemical. Try to cover liquid spills with foam. 5 OTHER INFORMATION
