Cumene hydroperoxide

Formed in phenol/acetone production; used as a polymerization initiator and curing agent for resins, plastics, rubber, and adhesives [2][3].

Mainly at work by inhaling vapors or mists and by skin contact; spills or fires can release irritating vapors; limited consumer exposure from some resin hardeners/adhesives [1][2][4].

Strong oxidizer and corrosive—can cause severe skin and eye burns, coughing, shortness of breath, headache, and dizziness; high exposure can harm lungs; also a fire/explosion hazard [1][2].

Workers in phenol/acetone plants, plastics/fiberglass shops, resin/adhesive manufacturing, transport and maintenance; people with asthma or skin disease; emergency responders [1][2].

Use closed systems/ventilation, wear chemical-resistant gloves and eye/face protection, avoid skin contact, and store away from heat and contaminants; follow spill/fire plans. For home/hobby use, choose peroxide-free products when possible, work in fresh air, wear gloves/eye protection, and follow labels; during a release, stay upwind and heed local guidance [1][2][4].
