1. Isolate the spill area, ensure adequate ventilation, and avoid dust formation when 4-Acetyl-1-naphthoic acid CAS 131986-05-5 is released, wearing full personal protective equipment including chemical-resistant gloves, safety goggles, and suitable respirator if necessary .
2. Collect 4-acetyl-1-naphthoic acid 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, following precautionary statement P501 .

1. 4-Acetyl-1-naphthoic acid CAS 131986-05-5 is not classified as highly flammable but may decompose under fire conditions, with a boiling point of approximately 442.9±28.0°C and a flash point predicted to be elevated, emitting toxic fumes when involved in a fire .
2. Use 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 4-acetyl-1-naphthoic acid should wear self-contained breathing apparatus and full protective gear when handling burning 4-Acetyl-1-naphthoic 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 .
