Repeated exposure to epoxy embedding resins may cause which health problem?

• A. Dermatitis
• B. Asthma
• C. Hair loss
• D. Nausea

Answer: (A)

Repeated skin contact with epoxy embedding resins commonly leads to dermatitis. These resins can irritate the skin and, over time, act as sensitizers. With repeated exposure, the immune system may react to the resin or hardener proteins bound to skin proteins, producing allergic contact dermatitis. This presents as redness, itching, and vesicles at the contact site. While inhalation of fumes from resins can irritate airways and, in some cases, contribute to asthma in sensitized individuals, dermatitis is the most typical health effect from ongoing skin exposure in a histology setting. Hair loss isn’t a typical outcome of epoxy exposure, and nausea is less directly linked to dermal contact unless there is significant ingestion or inhalation exposure.
