Objective

To provide employees with the knowledge and procedures necessary for the safe handling, storage, and disposal of acetone, minimizing the risk of fire, health hazards, and environmental contamination.

Introduction

Acetone is a highly flammable and versatile solvent used in many industries. This toolbox talk will cover the key safety aspects of handling acetone, including hazard identification, control measures, proper PPE, emergency procedures, and regulatory compliance.

Hazard Identification

Acetone presents several hazards, primarily due to its flammability and potential health effects. Understanding these hazards is crucial for implementing effective control measures.

• High Flammability: Acetone is a highly flammable liquid and vapor that can easily ignite at room temperature. Vapors can travel to ignition sources and flash back, causing fires or explosions. [1]

(Risk: High)

• Eye Irritation: Acetone is a severe eye irritant. Contact can cause sore, red eyes, tearing, and potential corneal damage. Vapors can also irritate the eyes. [2]

(Risk: Medium)

• Skin Irritation: Prolonged or repeated skin contact can cause mild irritation, dryness, redness, and cracking (dermatitis). Acetone can be absorbed through the skin. [2]

(Risk: Low)

• Inhalation Hazards: Inhalation of acetone vapors can irritate the nose and throat. High concentrations can affect the nervous system, causing headache, nausea, dizziness, drowsiness, confusion, and unconsciousness. [5]

(Risk: Medium)

• Reactivity Hazards: Acetone can react violently with oxidizing agents, organic acids, and strong reducing agents. It is incompatible with various materials, leading to potential fires or explosions. [1]

(Risk: Medium)

Control Measures

• Eliminate Ignition Sources: Keep acetone away from open flames, sparks, hot surfaces, and static discharge. Use non-sparking tools and equipment in areas where acetone is handled or stored. Post "No Smoking" signs. [4]
• Ensure Proper Ventilation: Use local exhaust ventilation and enclosure to control the concentration of acetone in the air. For large-scale use, employ non-sparking ventilation systems and explosion-proof equipment. [6]
• Electrically Bond and Ground Equipment: Electrically bond and ground all containers and equipment to prevent static discharge. Ensure ground clips contact bare metal. [4]
• Safe Storage Practices: Store acetone in a cool, well-ventilated area, away from direct sunlight, heat, and ignition sources. Keep containers tightly closed and properly labeled. [3]
• Implement Spill Control Measures: Have spill control materials readily available, such as absorbent materials that do not react with acetone. Develop and practice spill response procedures. [1]
• Regular Monitoring and Maintenance: Regularly inspect equipment, ventilation systems, and storage areas to ensure they are functioning correctly. Promptly address any leaks or spills.

Personal Protective Equipment (PPE) Requirements

• Eye Protection: Wear chemical safety goggles and a face shield when there is a potential for eye contact with acetone, especially during pouring or mixing operations. [6]
• Skin Protection: Wear chemical-resistant gloves, aprons, and boots to prevent skin contact. Suitable materials include butyl rubber, Silver Shield, and Tychem. Avoid prolonged or repeated skin contact. [6]
• Respiratory Protection: Use appropriate respiratory protection when engineering controls are not sufficient to maintain acetone concentrations below the recommended exposure limits. Options include chemical cartridge respirators with organic vapor cartridges or supplied-air respirators. [6]

Emergency Procedures

1. Inhalation: Move the affected person to fresh air immediately. If breathing is difficult, administer oxygen. If breathing has stopped, perform artificial respiration and seek immediate medical attention. [2]
2. Skin Contact: Remove contaminated clothing and flush the affected area with gently flowing water for at least 5 minutes. Use soap if available. If irritation persists, seek medical attention. [2]
3. Eye Contact: Immediately flush the contaminated eye(s) with gently flowing water for 15-20 minutes, holding the eyelid(s) open. Do not attempt to remove contact lenses. Seek immediate medical attention. [2]
4. Spills: Evacuate the area, eliminate all ignition sources, and ventilate the area. Contain and soak up the spill with an absorbent material that does not react with acetone. Place used absorbent into suitable, labeled containers for disposal. [1]
5. Fire: Use carbon dioxide, dry chemical powder, appropriate foam, or water spray/fog to extinguish acetone fires. Use water to keep non-leaking, fire-exposed containers cool. [1]

Questions and Answers

• Q: What should I do if I spill acetone?

A: Immediately evacuate the area, eliminate all ignition sources, and ventilate the area. Contain the spill with an appropriate absorbent material, and dispose of the waste properly. [1]

• Q: What type of gloves should I wear when handling acetone?

A: Wear chemical-resistant gloves made of materials such as butyl rubber, Silver Shield, or Tychem to prevent skin contact. [6]

• Q: What are the symptoms of acetone exposure?

A: Symptoms of acetone exposure can include irritation of the nose and throat, headache, nausea, dizziness, drowsiness, confusion, and eye irritation. [5]

Summary

Recap of main points:

• Acetone is a highly flammable liquid and vapor that can easily ignite. [1]
• Proper ventilation, elimination of ignition sources, and electrical bonding/grounding are crucial control measures. [4]
• Appropriate PPE, including chemical safety goggles, face shields, and chemical-resistant gloves, must be worn when handling acetone. [6]
• In case of a spill or fire, follow established emergency procedures and seek medical attention if necessary. [1]

Report all hazards, near-misses, and incidents to your supervisor immediately.
