Methyl methacrylate

Manufacturing of acrylic plastics/resins, dental and bone cements, paints/adhesives, and artificial nail products; releases from industrial sites and freshly applied materials [1][3].

Breathing vapors at work (plastics/resins, dental labs, nail salons) or during home projects; skin contact with liquid monomer; operating rooms during bone cement use; outdoor air near facilities [1][2][3].

Causes eye/skin/airway irritation, headaches, dizziness; can trigger or cause asthma and dermatitis with repeated contact; flammable. Not classifiable as a human carcinogen by IARC [1][2][4].

Workers in plastics/resins, dental and orthopedic settings, nail technicians; people with asthma; anyone in poorly ventilated spaces; pregnant workers should minimize exposure as a precaution [1][2][3].

Use local exhaust/source-capture ventilation; keep containers closed; wear chemical-resistant gloves and eye/skin protection; avoid skin contact and spills; allow full curing before occupancy; follow safety data sheets and workplace limits; consider lower-MMA alternatives [1][2][3].
