Hazard Statements: Causes severe skin burns and eye damage. May cause respiratory irritation. Flammable liquid and vapor.
Precautionary Statements: Keep away from heat, sparks, open flames. Wear protective gloves, clothing, eye and face protection. Avoid breathing vapors or mist. Wash hands thoroughly after handling.
Component: Acetic Acid
Concentration: 99-100% for glacial form, diluted forms have lower percentages
Synonyms: Vinegar acid, Methanecarboxylic acid
Impurities: Water, trace organics in technical grade
Other Components: No known significant impurities for analytical and reagent grades
Inhalation: Move person to fresh air. Seek immediate medical attention if breathing is difficult, coughing persists, or symptoms worsen.
Skin Contact: Remove contaminated clothing. Wash skin immediately with plenty of soap and water for several minutes. Get medical advice without delay.
Eye Contact: Rinse eyes gently with water for at least 15 minutes lifting upper and lower eyelids. Do not allow victim to rub eyes. Get emergency medical assistance.
Ingestion: Do not induce vomiting. Rinse mouth thoroughly. Never give anything by mouth to an unconscious person. Call physician or poison center right away.
Suitable Extinguishing Media: Carbon dioxide, alcohol-resistant foam, dry chemical
Unsuitable Extinguishing Media: Do not use water directly on flames as acetic acid is water miscible and water spray may spread the fire
Hazards from Combustion: Produces irritating or toxic fumes including carbon monoxide, carbon dioxide
Protective Equipment for Firefighters: Full protective gear and self-contained breathing apparatus recommended
Special Precautions: Vapors heavier than air can travel to ignition source and flash back. Cool exposed containers with water spray to prevent pressure build-up and possible explosion.
Personal Precautions: Evacuate area, ventilate well. Avoid inhalation of vapors. Keep people away from upwind direction.
Protective Equipment: Use chemical-resistant gloves, safety goggles, face shield, and suitable respiratory protection.
Environmental Precautions: Prevent material from entering drains, sewers, and waterways.
Method for Containment and Cleanup: Absorb with inert material like sand or earth. Collect in appropriate containers for disposal. Wash spill site with copious amounts of water after cleanup, ensuring runoff does not reach storm drains.
Handling: Work in a ventilated area. Use spark-proof tools and explosion-proof equipment. Avoid splashing and formation of mist.
Precautions: Do not breathe vapors or spray. Avoid contact with skin, eyes, clothing. Do not smoke around storage area. Keep away from combustible materials.
Storage: Store in tightly closed containers, in cool, dry, well-ventilated areas out of direct sunlight. Segregate from oxidizers, strong bases, and alkalines. Use containers resistant to corrosion, made from materials like glass, stainless steel, or specific plastics.
Special Considerations: Store away from food or animal feed. Keep upright and secure to prevent leaks or spills.
Occupational Exposure Limits: OSHA PEL: 10 ppm (25 mg/m3), ACGIH TLV: 10 ppm (25 mg/m3), Short-Term Exposure Limit: 15 ppm (37 mg/m3)
Ventilation: Use local exhaust ventilation to control airborne concentrations below exposure limits.
Respiratory Protection: Use NIOSH-approved respirators for vapor/mist if engineering controls do not maintain adequate levels.
Skin Protection: Wear chemical-resistant gloves (nitrile, neoprene), lab coats, aprons, and protective footwear.
Eye Protection: Use tight-fitting goggles and face shield.
