Epoxy resins and glycol methacrylate are both safe when exposed to skin.

• A. True
• B. False
• C. Not sure
• D. Depends on exposure duration

Answer: (B)

Skin contact with epoxy resins and glycol methacrylate is not safe. Epoxy resins contain reactive components that can penetrate the skin, causing irritation and, with repeated exposure, allergic contact dermatitis. The resin or curing agents can act as sensitizers, leading to dermatitis that may persist or worsen with ongoing exposure. Glycol methacrylate, used as a histology embedding resin, is also a skin irritant and can be a sensitizer, producing dermatitis with repeated contact. While fully cured epoxy is less hazardous, uncured epoxy and glycol methacrylate pose clear skin hazards and must be handled with proper gloves, protection, and hygiene. Therefore, saying they are safe with skin exposure is not correct.
