First Aid Measures

Inhalation: Move exposed individual to fresh air immediately; seek medical attention if symptoms such as coughing or difficulty breathing persist
Skin Contact: Remove contaminated clothing, promptly rinse affected skin with plenty of water and mild soap; seek medical advice if irritation develops or persists
Eye Contact: Rinse eyes thoroughly with plenty of water for several minutes, lifting upper and lower lids occasionally; remove contact lenses if present and easy to do; seek medical attention if discomfort continues
Ingestion: Rinse mouth with water without inducing vomiting; give water to drink if the person is conscious; seek medical attention if large quantities were swallowed or symptoms appear

Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, foam, dry chemical powder, or carbon dioxide to extinguish fire involving this compound
Unsuitable Extinguishing Media: Avoid high-pressure water streams that may spread the material or dust
Specific Hazards Arising from the Chemical: Decomposition in fire produces irritating and toxic gases, such as carbon oxides and aluminum oxides
Special Protective Equipment for Firefighters: Firefighters should wear full protective gear and self-contained breathing apparatus
Firefighting Instructions: Approach the fire from upwind and cool down unopened containers with water spray to prevent rupture due to heat

Accidental Release Measures

Personal Precautions: Wear protective clothing, chemical-resistant gloves, and eye/face protection to reduce the risk of exposure; ensure adequate ventilation in the area
Environmental Precautions: Prevent entry into drains, sewers, or watercourses; report large spills as required by local regulations
Method for Containment and Cleanup: Carefully collect spilled solid with shovel or dustpan, sweep up to minimize dust; place in suitable, labeled disposal containers; clean residue with plenty of water and ventilate area thoroughly

Handling and Storage

Handling: Avoid raising dust and minimize handling in open air; wash thoroughly after use; keep containers tightly sealed when not in use to avoid moisture absorption
Storage Conditions: Store in a cool, dry area away from incompatible materials including strong bases and oxidizers; keep out of reach of children and unauthorized personnel; containers should be clearly labeled and protected from physical damage
Specific Storage Requirements: Use corrosion-resistant containers, protect from direct sunlight and keep storage area clean; avoid excess humidity to prevent caking

Exposure Controls and Personal Protection

Occupational Exposure Limits: No specific regulatory limits for aluminum acetate; general limits for nuisance dust (OSHA PEL: 15 mg/m³ total dust; ACGIH TLV: 10 mg/m³ inhalable) apply
Engineering Controls: Use local exhaust ventilation or process enclosure where possible; general room ventilation as minimum
Personal Protective Equipment (PPE): Safety goggles or face shield, chemical-resistant gloves (nitrile, neoprene), lab coat or apron; use approved respirators if dust is generated and exposure limits may be exceeded
Hygiene Measures: Wash hands thoroughly after handling and before eating, drinking, or smoking; do not take contaminated clothing home

Other Information: Individuals with pre-existing skin, eye, or respiratory disorders may be more susceptible to effects; always use in moderation and follow recommended safety practices

Ecological Information

Ecotoxicity: Available data suggest low hazard for aquatic and terrestrial organisms at concentrations typically used; large spills could affect water pH and local aquatic life
Persistence and Degradability: Readily soluble in water, breaks down to acetate ions and aluminum ions which persist in environment
Bioaccumulative Potential: Not expected to bioaccumulate significantly
