1. 4-Acetyl-2-methylbenzoic acid must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment at 2-8°C, protected from light and moisture .
2. 4-acetyl-2-methylbenzoic acid CAS 55860-35-0 should be kept away from heat sources, open flames, and incompatible materials such as strong oxidizing agents, strong acids, and strong bases to prevent hydrolysis or decarboxylation .
3. Personnel must wear chemical-resistant gloves, safety goggles with side-shields, and protective clothing when handling this substance, as it causes skin irritation, serious eye irritation, and may cause respiratory irritation (H315, H319, H335) .
4. Avoid formation of dust and aerosols, ensure adequate ventilation in work areas (preferably a chemical fume hood), wash thoroughly after handling, and follow precautionary statements P261, P280, P302+P352, and P305+P351+P338 .

1. Isolate the spill area, ensure adequate ventilation, and avoid dust formation when 4-Acetyl-2-methylbenzoic acid is released, wearing full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable respirator if necessary .
2. Collect 4-acetyl-2-methylbenzoic acid CAS 55860-35-0 by sweeping or vacuuming without creating dust, using non-sparking tools, and place into suitable closed containers for disposal, cleaning up spills immediately .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure, and prevent the product from entering drains or water courses due to potential environmental hazards .
4. Dispose of collected material according to local, state, and federal environmental regulations, as the substance may have environmental hazards requiring proper waste management .

1. 4-Acetyl-2-methylbenzoic acid is not classified as highly flammable but may decompose under fire conditions, with a boiling point of approximately 352.7°C and a flash point of 181.3°C, emitting toxic fumes when involved in a fire .
2. Use 4-acetyl-2-methylbenzoic acid CAS 55860-35-0 dry chemical powder, carbon dioxide, alcohol-resistant foam, or water spray to extinguish fires involving the product, selecting appropriate extinguishing media based on surrounding environment .
3. Firefighters should wear self-contained breathing apparatus and full protective gear when handling burning 4-Acetyl-2-methylbenzoic acid due to hazardous decomposition gases including carbon monoxide, carbon dioxide, and other toxic fumes generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; move containers from the fire area if safe to do so, cool exposed containers with water spray, and contain fire runoff to prevent environmental contamination .
