Butyl 2-methylprop-2-enoate requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or use local exhaust ventilation to prevent vapor accumulation. Avoid skin and eye contact as the substance causes irritation and skin sensitization. Keep away from heat sources, sparks, and open flames due to its flammable nature. Use non-sparking tools and ensure proper grounding of equipment during transfer operations.

Butyl 2-methylprop-2-enoate must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames. Keep containers tightly closed and store below 25°C to prevent polymerization. The substance should be separated from strong oxidizing agents, acids, and bases. Use original containers or compatible materials for storage. Implement appropriate fire prevention measures in storage areas and ensure containers are properly labeled according to GHS requirements.

Skin contact with butyl 2-methylprop-2-enoate requires immediate removal of contaminated clothing and thorough washing with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air and keep at rest. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician if symptoms of irritation or sensitization develop.

Butyl 2-methylprop-2-enoate disposal must comply with local, national, and European waste regulations including the Waste Framework Directive. The substance should be treated as hazardous waste and disposed of through licensed waste management facilities. Incineration at high temperatures in approved facilities is typically the preferred method. Do not discharge into sewers, water bodies, or soil. Small quantities may be absorbed on inert material and disposed of according to local hazardous waste regulations.
