6.1 Personal Precautions, Protective Equipment and Emergency Procedures

For Non-Emergency Personnel: Evacuate personnel to safe areas upwind. Eliminate all ignition sources (no smoking, flares, sparks, or flames). Ensure adequate ventilation. Do not breathe vapors, mist, or dust. Avoid contact with skin, eyes, and clothing. Wear appropriate personal protective equipment (see Section 8).

For Emergency Responders: Wear positive-pressure self-contained breathing apparatus (SCBA) and chemical-resistant, antistatic protective clothing. Use clean, non-sparking, explosion-proof tools. Ground and bond all handling equipment.

6.2 Environmental Precautions

Prevent further leakage or spillage if safe to do so. Prevent spilled material from entering drains, sewers, waterways, and soil. Inform environmental authorities if spillage causes environmental contamination.

6.3 Methods and Materials for Containment and Cleaning Up

Small Spill Clean-up: Absorb spillage with sand or other non-combustible material. Use clean, non-sparking tools to collect absorbed material into compatible containers. Seal containers and move out of spill area. Ensure static grounding and bonding during transfer, with nitrogen blanketing if required.

Large Spill Clean-up: Construct dikes or dig trenches for containment. Seal drainage pipelines. Cover with alcohol-resistant foam (for water-immiscible flammable liquids) / sand / non-combustible material to suppress vapor evaporation. Transfer using explosion-proof pump (or corrosion-resistant pump if corrosive) to tank truck or designated collector. Ensure static grounding and bonding during transfer, with nitrogen blanketing if required.

Prevention of Secondary Hazards: Prevent aerosol formation in air;

7.1 Precautions for Safe Handling

Use only in well-ventilated areas. Keep away from heat, hot surfaces, sparks, open flames, and other ignition sources. No smoking. Use explosion-proof ventilation system and equipment. Use non-sparking tools. Take precautionary measures against static discharge. Ground/bond container and receiving equipment. Avoid contact with skin, eyes, and clothing. Avoid breathing vapors, mist, or dust.

Hygiene Measures: Prohibit eating, drinking, and smoking in work and storage areas. Wash hands thoroughly with soap and water after handling and before breaks. Remove contaminated clothing and protective equipment before entering eating areas.

7.2 Conditions for Safe Storage, including Any Incompatibilities

Store in original tightly closed container in a cool, dry, and well-ventilated area away from direct sunlight, heat, sparks, open flames, and incompatible materials. Storage facilities must be equipped with explosion-proof electrical systems, static grounding, and lightning protection. Use explosion-proof lighting, ventilation systems, and electrical equipment.

Biological Limit Values: ACGIH Biological Exposure Indices (BEIs):
• Acetone in urine: 25 mg/L (Sampling Time: End of shift, Notation: Ns)

8.2 Appropriate Engineering Controls

Provide adequate explosion-proof local exhaust ventilation and general ventilation to maintain airborne concentrations below occupational exposure limits. Ventilation systems must be grounded and bonded against static electricity. Emergency eyewash fountains and safety showers must be readily accessible in the immediate work area.

The most important known symptoms and effects include: Highly Flammable liquid and vapor; Causes serious eye irritation; May cause drowsiness or dizziness.

11.4 Delayed and Immediate Effects from Short and Long-Term Exposure

Immediate and delayed effects after short and long-term exposure are consistent with GHS hazard classifications (see Section 2).

11.5 Interactive Effects

No interactive effects data available.

12.1 Toxicity (Aquatic and Terrestrial): EC50; Species: Artemia salina (Brine shrimp) 2-3 instar nauplii; Conditions: saltwater, static, 25 °C; Concentration: 14852000 ug/L for 24 hr (95% confidence interval: 14141000-15563000 ug/L); Effect: intoxication, immobilization

12.2 Persistence and Degradability: AEROBIC: The percent theoretical BOD of acetone in water seeded with settled domestic sewage was 56%, 76%, 83% and 84%, over 5, 10, 15 and 20 day incubation periods(1). Percent theoretical BOD's of acetone in a raw sewage inocula were reported as 37% and 81% over 5 and 20 day incubation periods, respectively(2), 54% over a 5 day incubation period(3), 71% over a 7 day incubation period(4), 55% and 72% over 5 day and 10 day incubation periods respectively(5) and 38% over a 5 day incubation period(6). The percent theoretical BOD of acetone in freshwater was reported as 56%, 76%, 83% and 84% over 5, 10, 15 and 20 day incubation periods, respectively(7). The percent theoretical BOD of acetone in seawater was reported as 38%, 67%, 69% and 76% over 5, 10, 15 and 20 day incubation periods, respectively(7). Acetone, present at 100 mg/L, reached 96% of its theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test which classified the compound as readily biodegradable(8). Using OECD Guideline 301B (Ready Biodegradability: CO2 Evolution Test), acetone was found to be readily biodegradable with 60% degradation after 5 days and 90.9% CO2 evolution after 28 days(9).

12.3 Bioaccumulative Potential: An estimated BCF of 3 was calculated in fish for acetone(SRC), using a log Kow of -0.24(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that the potential for bioconcentration in aquatic organisms is low(SRC). In a 1931 test report, a BCF value of 0.69 was determined for adult haddock fish over an 11 hour exposure period(4); however, the test protocol does not meet important criteria of current standard BCF methods(4).

12.4 Mobility in Soil: Using a structure estimation method based on molecular connectivity indices(1), the Koc of acetone can be estimated to be 2.4(SRC). According to a classification scheme(2), this estimated Koc value suggests that acetone is expected to have very high mobility in soil. In sorption studies, acetone showed no adsorption to montorillonite, kaolinite clay, or stream sediment(3,4).

12.5 Results of PBT and vPvB Assessment: No specific PBT or vPvB assessment data available.

12.6 Endocrine Disrupting Properties: No specific data available regarding endocrine disrupting properties in the environment.

12.7 Other Adverse Effects: No other adverse environmental effects (such as ozone depletion potential or global warming potential) are known from available data.
