Section 2: Hazard Identification – Understanding the Risks

This is arguably the most critical section for everyday personal care use, summarizing the dangers.

• Hazard Classification: Acetone is typically classified as a “Flammable Liquid – Category 2” and an “Eye Irritant – Category 2A” and “Specific Target Organ Toxicity – Single Exposure (Narcotic Effects) – Category 3.”
  • Actionable Example: Knowing “Flammable Liquid – Category 2” immediately tells you to keep acetone away from all heat sources, open flames, and sparks, even static discharge, when doing your nails. This means no candles, no smoking, and avoiding electronic devices that could spark nearby.
• Signal Word: For acetone, this will be “DANGER.” This bold word signals the severity of the hazards.
  • Actionable Example: Seeing “DANGER” on a product containing acetone should prompt you to slow down, read the rest of the safety information carefully, and exercise extreme caution, even for routine tasks like nail polish removal.
• Hazard Statements (H-Codes): These are standardized phrases describing the nature of the hazard. For acetone, you’ll typically see:
  • H225: Highly flammable liquid and vapor.
    • Actionable Example: This means acetone vapors can easily ignite at room temperature. Always use acetone in a well-ventilated area, and ensure no open flames, pilot lights (like from a water heater), or electrical sparks are present. If you spill it, the vapors can travel along the floor to an ignition source.
  • H319: Causes serious eye irritation.
    • Actionable Example: When removing nail polish, be extra careful not to splash acetone into your eyes. If it happens, flush your eyes immediately with plenty of water for at least 15-20 minutes, holding your eyelids open, and seek medical attention if irritation persists. Wearing safety glasses (though less common for personal care, it’s the professional recommendation) would prevent this entirely.
  • H336: May cause drowsiness or dizziness.
    • Actionable Example: This indicates potential central nervous system effects from inhaling high concentrations of vapor. When using nail polish remover, ensure the room is well-ventilated. Open windows, use a fan, or go to an outdoor area if possible. If you start to feel lightheaded or dizzy, immediately move to fresh air.
• Precautionary Statements (P-Codes): These tell you how to prevent, respond to, store, and dispose of the chemical safely.
  • Prevention (P200s):
    • P210: Keep away from heat/sparks/open flames/hot surfaces. No smoking.
      • Actionable Example: Don’t do your nails near a lit candle, a gas stove, or while smoking. If you’re doing them at a table, clear away any potential ignition sources.
    • P261: Avoid breathing vapor.
      • Actionable Example: Use acetone in a well-ventilated area. If you’re regularly using it (e.g., as a nail technician), consider local exhaust ventilation or even a respirator designed for organic vapors. For home use, open windows wide.
    • P264: Wash skin thoroughly after handling.
      • Actionable Example: After removing nail polish, wash your hands thoroughly with soap and water to remove any residual acetone, especially before eating or touching your face.
    • P280: Wear protective gloves/eye protection/face protection.
      • Actionable Example: While most consumers don’t wear gloves for a quick nail polish removal, for prolonged use, chemical-resistant gloves (like butyl rubber or nitrile, not latex or vinyl, which acetone can permeate) are recommended. If you’re prone to splashes or using larger quantities, consider eye protection.
  • Response (P300s):
    • P303 + P361 + P353: IF ON SKIN (or hair): Take off immediately all contaminated clothing. Rinse skin with water/shower.
      • Actionable Example: If you spill a significant amount on your skin or clothes, immediately remove the affected clothing and wash the skin thoroughly with soap and water.
    • P304 + P340: IF INHALED: Remove person to fresh air and keep comfortable for breathing.
      • Actionable Example: If you or someone nearby is experiencing respiratory irritation or dizziness from acetone fumes, move them to an area with plenty of fresh air.
    • P305 + P351 + P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
      • Actionable Example: As mentioned, immediately flush eyes with water. The “cautiously” part implies gentle flushing, not a strong jet. Remove contact lenses only if it’s easy and doesn’t cause more irritation.
  • Storage (P400s):
    • P403 + P233: Store in a well-ventilated place. Keep container tightly closed.
      • Actionable Example: Don’t store your nail polish remover in a hot car or near a heat vent. Keep the lid tightly sealed when not in use to prevent evaporation and the buildup of flammable vapors.
    • P403 + P235: Store in a well-ventilated place. Keep cool.
      • Actionable Example: A cool, dry cupboard away from direct sunlight is ideal, rather than on a bathroom counter where temperatures can fluctuate or near heating appliances.
  • Disposal (P500s):
    • P501: Dispose of contents/container in accordance with local/regional/national/international regulations.
      • Actionable Example: Don’t pour leftover acetone down the drain. While small amounts in cosmetic waste (like a cotton ball) can go into regular trash once dried, larger quantities or pure acetone may require hazardous waste disposal, depending on local regulations. Check with your local waste management facility for specific instructions.
• Other Hazards Not Otherwise Classified: This section may list other relevant hazards, such as repeated exposure causing skin dryness or cracking (EUH066).
  • Actionable Example: If you frequently use acetone, be aware that it can strip natural oils from your skin, leading to dryness and cracking. Moisturize your hands regularly to counteract this effect.

Section 3: Composition/Information on Ingredients – What’s Inside?

This section lists the chemical ingredients and their concentrations. For pure acetone, it will simply state “Acetone” with its CAS (Chemical Abstracts Service) number (67-64-1) and typically 100% concentration. In nail polish removers, there might be other ingredients like emollients or fragrances, but acetone will be the primary hazardous component.

• Actionable Example: If you have allergies or sensitivities, checking this section for other ingredients (though less common for pure acetone) can help identify potential triggers. For acetone itself, the focus remains on its inherent hazards.

Section 4: First-Aid Measures – Immediate Action for Incidents

This section provides clear, concise instructions for emergency situations.

• Description of First Aid Measures:
  • Inhalation: “Move victim to fresh air. If not breathing, give artificial respiration. Get medical attention as soon as possible.”
    • Actionable Example: If you accidentally inhale a large amount of acetone vapor and feel unwell, immediately go outdoors or to a well-ventilated area. If symptoms like difficulty breathing persist, call emergency services.
  • Skin Contact: “Take off contaminated clothing, shoes, and leather goods. Flush with gently flowing water for 5 minutes. Use soap if available. If irritation or pain persists, get medical attention.”
    • Actionable Example: If you spill acetone on your skin, wash the area thoroughly with soap and water. If irritation develops or is severe, consult a doctor. Remember to wash any contaminated clothing before wearing it again.
  • Eye Contact: “Immediately flush the contaminated eye(s) with gently flowing water for 15-20 minutes while holding the eyelid(s) open. If a contact lens is present, DO NOT delay flushing or attempt to remove the lens. Take care not to rinse contaminated water into the unaffected eye or onto the face.”
    • Actionable Example: This is a crucial instruction. The emphasis is on immediate and prolonged flushing, without trying to remove contact lenses first, to minimize damage.
  • Ingestion: “Not harmful if small amounts are ingested. If large amounts are ingested: Can cause effects as described for inhalation. DO NOT induce vomiting unless directed by medical personnel. If victim is conscious, give small quantities of water to drink. Consult a physician.”
    • Actionable Example: If acetone is accidentally swallowed, do not try to make the person vomit. Give them a small amount of water to drink (if conscious) and seek immediate medical attention, bringing the product container or SDS with you.
• Most Important Symptoms/Effects, Acute and Delayed: This summarizes what to look for after exposure. For acetone, this includes eye irritation, skin dryness/cracking, headaches, dizziness, and central nervous system depression from inhalation.
  • Actionable Example: If you experience any of these symptoms after using an acetone-containing product, recognize them as potential effects and act according to the first aid instructions.
• Indication of Immediate Medical Attention and Special Treatment Needed: This guides medical professionals on specific treatments.
  • Actionable Example: While primarily for medical staff, this section reinforces the need for professional help in severe cases and highlights any unique treatment considerations for acetone exposure.

Section 5: Fire-Fighting Measures – What to Do in Case of Fire

Given acetone’s flammability, this section is vital.

• Suitable Extinguishing Media: For acetone, this will typically include “Alcohol-resistant foam,” “Dry chemical,” or “Carbon dioxide (CO2).” Water may be ineffective or even spread the fire if used incorrectly on large spills.
  • Actionable Example: If a small fire starts near acetone (e.g., from a spilled bottle igniting), do NOT use water directly on the liquid. Use a fire extinguisher rated for flammable liquids (Class B). If you don’t have one, evacuate immediately and call emergency services.
• Specific Hazards Arising from the Chemical: “Highly flammable liquid and vapor. Vapors are heavier than air and may spread along floors. Vapors may form explosive mixtures with air. Containers may rupture violently when heated.”
  • Actionable Example: This reinforces the danger of acetone vapors accumulating in low-lying areas and the potential for explosive mixtures. It’s why ventilation is so critical and why you should never store large quantities near heat sources. If there’s a fire, get out and let professionals handle it.
• Special Protective Equipment and Precautions for Firefighters: This details the equipment and procedures for trained personnel.
  • Actionable Example: This underlines that acetone fires are serious and require specialized handling, reinforcing the need for immediate evacuation and professional assistance rather than attempting to fight a significant fire yourself.

Section 6: Accidental Release Measures – Spill Response

This section outlines how to handle spills safely.

• Personal Precautions, Protective Equipment, and Emergency Procedures: “Evacuate the area immediately. Isolate the hazard area. Keep out unnecessary and unprotected personnel. Eliminate all ignition sources. Use grounded, explosion-proof equipment. Increase ventilation to the area or move leaking container to a well-ventilated and secure area.”
  • Actionable Example: If you spill a significant amount of acetone, immediately open windows, turn off any pilot lights or electrical appliances, and ensure no open flames are nearby. Keep pets and children away from the spill area.
• Environmental Precautions: “Prevent product from entering drains. Prevent further leakage or spillage if safe to do so. If the product contaminates rivers and lakes or drains inform respective authorities.”
  • Actionable Example: Do not wash large spills down the sink or drain. This prevents environmental contamination and fire hazards in plumbing systems.
• Methods and Materials for Containment and Clean-up: “Contain and soak up spill with absorbent that does not react with spilled product (e.g., sand, inert absorbent). Contaminated absorbent poses the same hazard as the spilled product. Place used absorbent into suitable, covered, labelled containers for disposal. Flush spill area.”
  • Actionable Example: For small spills (e.g., a few drops of nail polish remover), a paper towel is usually fine, but dispose of it immediately and ensure the area is well-ventilated. For larger spills, use an absorbent material like cat litter or sand (NOT sawdust or other combustible materials) and then carefully collect the soaked material in a non-plastic, sealed container for appropriate hazardous waste disposal.

Section 7: Handling and Storage – Safe Daily Practices

This section provides practical advice for safe routine use.

• Precautions for Safe Handling: “Avoid formation of aerosol. Do not breathe vapours/dust. Avoid exposure – obtain special instructions before use. Avoid contact with skin and eyes. For personal protection see section 8. Smoking, eating and drinking should be prohibited in the application area. Take precautionary measures against static discharges. Provide sufficient air exchange and/or exhaust in work rooms. Open drum carefully as content may be under pressure.”
  • Actionable Example: This reiterates the importance of ventilation and avoiding inhalation. Never spray pure acetone. If you’re doing your nails, don’t eat or smoke in the same area. For larger containers, ground them if transferring, to prevent static sparks.
• Conditions for Safe Storage, Including any Incompatibilities: “No smoking. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Observe label precautions. Keep away from heat and sources of ignition. Keep away from direct sunlight. Store away from incompatible substances (oxidizing agents, strong acids, strong bases).”
  • Actionable Example: Store nail polish remover in a cool, dry, dark place, away from any heat sources, appliances that generate heat, or direct sunlight. Ensure the cap is always screwed on tightly to prevent evaporation and vapor buildup. Keep it out of reach of children and pets. Do not store it next to bleaches or strong cleaning agents.

Section 8: Exposure Controls/Personal Protection – Your Shield

This section details the measures to minimize exposure, especially important for regular or prolonged use.

• Control Parameters (Exposure Limits): This lists occupational exposure limits (e.g., OSHA PEL, ACGIH TLV). While primarily for workplaces, it highlights the levels at which acetone can become hazardous.
  • Actionable Example: These numbers indicate that even in low concentrations over time, acetone can have effects. For personal care, this reinforces the need for good ventilation, as your exposure will be significantly higher in a poorly ventilated space.
• Appropriate Engineering Controls: “Provide sufficient mechanical ventilation (general or local exhaust) to maintain vapor exposures below recommended limits.”
  • Actionable Example: For salon professionals, this means proper ventilation systems are non-negotiable. For home users, it translates to opening windows and using fans to disperse vapors. Don’t rely solely on natural air movement in a small, enclosed bathroom.
• Individual Protection Measures (PPE):
  • Eye/Face Protection: “Wear chemical safety goggles and face shield when contact is possible. Eye wash bottle with pure water.”
    • Actionable Example: While full goggles aren’t practical for typical home use, being mindful of splashes and having immediate access to water for flushing eyes is essential.
  • Skin Protection: “Avoid repeated or prolonged skin contact. Wear chemical protective clothing e.g., gloves, aprons, boots.”
    • Actionable Example: For frequent nail polish removal or if your skin is sensitive, consider wearing nitrile gloves (ensure they are acetone-resistant) to minimize direct skin contact and prevent dryness. Moisturize your hands regularly.
  • Respiratory Protection: “Respiratory protection is not required for normal use. Where concentrations are above recommended limits or are unknown, appropriate respiratory protection should be worn (e.g., organic vapor respirator).”
    • Actionable Example: For occasional home use, good ventilation is usually sufficient. However, if you are regularly exposed to high concentrations of acetone (e.g., in a poorly ventilated salon environment), wearing a respirator specifically designed for organic vapors can provide critical protection against inhalation hazards.
  • Hygiene Measures: “Wash hands before breaks and after work. Keep away from food, drink and animal feedingstuffs. When using do not smoke. Remove contaminated clothing and wash before reuse.”
    • Actionable Example: Always wash your hands thoroughly after using acetone, especially before eating or drinking. Don’t touch your face or eyes with acetone-contaminated hands.

Section 9: Physical and Chemical Properties – How Acetone Behaves

This section provides technical data about acetone’s characteristics, offering insight into its hazards.

• Appearance (e.g., Clear, Colorless Liquid), Odor (Sweet, Pungent), pH, Boiling Point, Flash Point:
  • Flash Point: For acetone, this is typically very low (e.g., -20°C or -4°F). This is a critical indicator of its flammability.
    • Actionable Example: A low flash point means acetone can ignite easily at typical room temperatures, even from a distant ignition source. This reinforces the “no open flames” rule with extreme urgency.
  • Vapor Pressure: High vapor pressure indicates a substance evaporates quickly, leading to higher concentrations of vapor in the air.
    • Actionable Example: Acetone’s high vapor pressure explains why it evaporates so rapidly and why ventilation is crucial to prevent dangerous vapor buildup.
  • Vapor Density: Acetone vapors are heavier than air.
    • Actionable Example: This means acetone vapors will settle in low-lying areas (like floors, sinks, or basements) and can travel considerable distances to an ignition source, then flash back. Ensure ventilation at floor level if possible, and be extra cautious about ignition sources in lower areas of a room.

Section 10: Stability and Reactivity – How Acetone Interacts

This section details how acetone behaves under various conditions and what substances it reacts with.

• Reactivity/Chemical Stability: “Normally stable. Vapors may form explosive mixture with air.”
  • Actionable Example: Acetone itself is stable, but its vapors are highly reactive with air, creating explosive mixtures. This highlights that the danger isn’t just the liquid, but the invisible gas it creates.
• Possibility of Hazardous Reactions: “Reacts violently with oxidizing agents (e.g., peroxides), organic acids (e.g., acetic acid), strong reducing agents (e.g., hydrides).”
  • Actionable Example: Never mix acetone with other chemicals, especially household cleaners like bleach or strong acids. This can create dangerous reactions, including toxic fumes or explosions. Only use acetone as intended for its specific personal care purpose.
• Conditions to Avoid: “Open flames, sparks, static discharge, heat and other ignition sources. Prolonged exposure to sunlight.”
  • Actionable Example: Store acetone away from direct sunlight, which can increase its temperature and vapor pressure, intensifying its flammability hazard.
• Incompatible Materials: (See above under “Possibility of Hazardous Reactions”)

• Hazardous Decomposition Products: “In the event of fire: Carbon monoxide (CO), Carbon dioxide (CO2).”

  • Actionable Example: If acetone burns, it releases toxic fumes. This further emphasizes evacuating in case of fire.

Section 11: Toxicological Information – Health Effects in Detail

This section provides comprehensive data on the potential health effects from various exposure routes.

• Routes of Exposure: Typically lists “Inhalation,” “Skin Contact,” “Eye Contact,” and “Ingestion.”

• Symptoms Related to Exposure:

  • Inhalation: “Irritation of nose and throat. At high concentrations: headache, nausea, dizziness, drowsiness, confusion. Severe exposure can cause unconsciousness.”
    • Actionable Example: If you’re doing your nails and feel a burning sensation in your nose or throat, or start to feel dizzy, immediately move to fresh air. These are early warning signs of overexposure.
  • Skin Contact: “May cause mild irritation. Can cause dry, red, cracked skin (dermatitis) following prolonged or repeated skin contact.”
    • Actionable Example: Regular or prolonged direct skin contact with acetone will dehydrate your skin. Use hand cream and consider gloves if you frequently use it.
  • Eye Contact: “Causes moderate to severe irritation. Symptoms include sore, red eyes, and tearing. The vapor also irritates the eyes.”
    • Actionable Example: Even acetone vapor can irritate your eyes, especially in a poorly ventilated space. If your eyes feel dry or red after using it, ensure better ventilation next time.
  • Ingestion: “Not harmful if small amounts. If large amounts: effects as described for inhalation.”

• Chronic Effects: “Can cause dry, red, cracked skin (dermatitis) following skin contact. May harm the nervous system (limited studies).”

  • Actionable Example: Long-term, repeated exposure, even at low levels, can have cumulative effects. This reinforces the importance of consistent safety practices like ventilation and skin protection.
• Carcinogenicity/Mutagenicity/Reproductive Toxicity: Acetone is generally not classified as a carcinogen, mutagen, or reproductive toxin by major agencies.
  • Actionable Example: This offers some reassurance regarding long-term, serious health concerns, but does not negate the immediate and acute hazards discussed previously.

Section 12-16: Ecological, Disposal, Transport, Regulatory, and Other Information

While these sections are generally more relevant for industrial users and emergency responders, they can offer some insights for consumers:

• Section 12: Ecological Information: Discusses environmental impact.
  • Actionable Example: Acetone is generally not highly persistent in the environment, but it’s still best practice to prevent large spills from entering waterways (as covered in Section 6).
• Section 13: Disposal Considerations: Reiterates disposal instructions.
  • Actionable Example: Again, this section emphasizes that proper disposal is crucial. Do not pour pure acetone down the drain. For small, absorbed amounts on cotton balls, allow them to dry completely before discarding in regular trash.
