Section III - Hazards Identification
Overview: May be harmful if swallowed. May be irritating to skin eyes and respiratory tract.
Safety Ratings
Health: Moderate Flammability: Severe Reactivity: Slight Contact: Slight
Recommended safety equipment: safety goggles, lab coat and proper gloves
Storage: General storage
NFPA Ratings
Health = 2 Flammability = 4 Reactivity = 1
Potential Health Effects
The vapor and liquid are highly flammable. Acetone is irritating to the skin, eyes and mucous membranes. Ingestion
will result in coma and death. The toxicology of this compound have not been completely examined. It is presumed
that the toxicity of this item is similar to other ketones.
Inhalation: Irritating
Ingestion: While the toxicity of this compound is low, large doses may cause nausea, vomiting, diarrhea, etc.
Skin contact: Acetone is a strong skin irritant and a defatting agent.
Eye contact: May be irritating.
Chronic Exposure: May cause cracking of skin and/or dermatitis.
Aggravation of preexisting conditions: Preexisting eye, skin, and respiratory conditions may be aggravated
Section IV - First Aid Measures
Inhalation: Remove from source of exposure and get medical attention for any breathing difficulty.
MSDS Sudan III, page 1 of 3
Ingestion: Do not induce vomiting. Aspiration of acetone into the lungs may produce death. Get immediate medical
attention even if symptoms improve.
Skin Contact: Wash affected area with soap and water. Get medical advice if irritation develops.
Eye Contact: Rinse thoroughly with running water. Get medical advice if irritation develops.
Section V - Fire Fighting Measures
Flash point: -18oC (0oF) TCC
Flammable Limits: LEL 3% UEL 13%
Fire: Because of the low flash point acetone is a severe fire Hazard.
Explosion: Vapor in air may form an explosive mixture. Sensitive to static discharge.
Fire Extinguishing Media: Alcohol foam, carbon dioxide or dry chemical.
Special information: Pyrolysis will release corrosive oxides.
Section VI - Accidental Release Measures
Remove sources of ignition, absorb with a suitable absorbent and store in a suitable container for disposal.
Section VII - Handling and Storage
Store in a closed container away from sources of ignition. Drums should be bonded and grounded to avoid static
discharge.
Section VIII - Exposure Control/Personal Protection
Airborne Exposure Limits: See section II
Ventilation System: Local exhaust such as explosion proof chemical fume hoods are recommended. When required,
Refer to the ACGIH document, "Industrial Ventilation, a Manual of Recommended Practices" for details about
ventilation.
Personal Respirator: Usually not required. In case of emergency, or when exposure levels are unknown, use a positive
pressure, full face piece, air supplied respirator.
Skin protection: Protective gloves and clothing are recommended.
Eye Protection: Laboratory safety goggles or similar products are required as part of good laboratory practice.
Section IX - Physical and Chemical Properties
Boiling Point: 56oC @ 760 mm Hg Density: 0.84 g/ml
Vapor pressure (mm Hg): Unknown Evaporation Rate( n-butyl alcohol = 1): Unknown
Vapor Density (air = 1): Unknown Solubility: Infinitely miscible with water
Appearance and Odor: A clear red liquid with the characteristic odor of acetone.
Section X - Stability and Reactivity
Stability: Stable.
Hazardous Decomposition Products: Nothing unusual.
Hazardous polymerization: Will not occur.
Incompatibilities: Store away from oxidizers.
Conditions to avoid: Sources of ignition.
Section XI - Toxicological Information
For pure acetone:
Oral mouse LD50 = 3000 mg/kg
Inhalation Rat LCLo = 16000 ppm/4 Hr

Cancer lists
Ingredient Known Carcinogenicity? NTP? Anticipated? IARC Category
Acetone no no no none
Sudan III no no no none
Ethanol no no no none
Methanol no no no none
Isopropanol no no no 3
Section XII - Ecological Information
Environmental Fate: Acetone is biodegradable and not expected to accumulate in the environment.
Environmental Toxicity: Acetone is not expected to be toxic to fish. Ethanol evaporates quickly and is not expected to
bioaccumulate. The material is removed from the air by dry and liquid adsorption. The half-life for ethanol in the
atmosphere is one to ten days.
Section XIII - Disposal
Local governments may restrict the amounts of flammable liquids that may be flushed down drain. Insure compliance
with all government regulation
Section XIV - Transportation information
