Methyl 3-(3-tert-butyl-4-hydroxy-5-methylphenyl)propanoate requires careful handling due to its Acute Tox. 4 classification. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or use local exhaust ventilation to minimize exposure. Avoid skin and eye contact, and prevent inhalation of vapors or dust. Wash hands thoroughly after handling and before eating or drinking.

Methyl 3-(3-tert-butyl-4-hydroxy-5-methylphenyl)propanoate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep away from incompatible materials such as strong oxidizing agents. Storage areas should be equipped with appropriate spill containment measures due to its aquatic toxicity classification. Maintain proper inventory rotation and ensure containers are properly labeled with hazard information.

In case of skin contact with methyl 3-(3-tert-butyl-4-hydroxy-5-methylphenyl)propanoate, immediately wash the affected area with plenty of water and soap for at least 15 minutes. For eye contact, rinse immediately with clean water for at least 15 minutes. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek medical attention. Remove contaminated clothing and seek medical advice if symptoms persist.

Methyl 3-(3-tert-butyl-4-hydroxy-5-methylphenyl)propanoate must be disposed of through authorized hazardous waste disposal facilities due to its toxicity classification. Never discharge into sewers, waterways, or soil due to its Aquatic Chronic 2 classification. Collect waste in appropriate containers, clearly labeled with contents and hazard information. Contact licensed waste management companies for proper collection and treatment according to local and European waste regulations.

Methyl 3-(3-tert-butyl-4-hydroxy-5-methylphenyl)propanoate is classified as ADR Class 9 (Miscellaneous dangerous substances), Packing Group III. Transportation requires appropriate UN-specification packaging with proper marking and labeling including hazard pictograms GHS07 and GHS09. Transport documents must include the correct shipping name, UN number, and hazard class. Ensure vehicles are equipped for hazardous material transport and drivers hold appropriate certifications.
