4-[2-(4-hydroxyphenyl)propan-2-yl]phenol requires careful handling due to its classification as Repr. 1B, Eye Dam. 1, and Skin Sens. 1. Essential PPE includes chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume extraction to avoid inhalation. Prevent skin and eye contact, and avoid generating dust. Ensure emergency eyewash stations and safety showers are accessible during handling operations.

4-[2-(4-hydroxyphenyl)propan-2-yl]phenol should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers upright and properly labeled according to CLP requirements. Store away from incompatible materials such as strong oxidizing agents. Maintain storage temperatures below 25°C when possible and ensure adequate containment measures to prevent environmental release due to its aquatic toxicity classification.

Immediate action is required due to the compound's Eye Dam. 1 classification. For eye contact, rinse immediately with plenty of water for at least 15 minutes and seek immediate medical attention. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water. If inhaled, move to fresh air immediately. Due to its reproductive toxicity classification, seek medical advice promptly for any significant exposure incident.

4-[2-(4-hydroxyphenyl)propan-2-yl]phenol must be disposed of as hazardous waste due to its Aquatic Acute 1 and Aquatic Chronic 1 classifications. Contact licensed waste disposal companies authorized to handle chemical waste. Never discharge to sewers, watercourses, or soil. Contaminated packaging should be treated as hazardous waste. Follow local and EU regulations including the Waste Framework Directive for proper classification and disposal documentation.

4-[2-(4-hydroxyphenyl)propan-2-yl]phenol is classified under ADR as Class 9 (Miscellaneous dangerous goods), Packing Group III. Transportation requires appropriate UN specification packaging and proper dangerous goods documentation. Vehicles must carry appropriate emergency equipment and drivers need ADR certification. Packages must display correct hazard labels and markings according to dangerous goods regulations. Ensure compliance with national and international transport regulations for hazardous materials.

4-[2-(4-hydroxyphenyl)propan-2-yl]phenol is subject to REACH regulation requiring registration for manufacture or import above one tonne annually.
