What safety practice is recommended when using EMA?

• A. Wear no protective gear when handling EMA
• B. Apply EMA to the skin to test reaction
• C. Keep monomer away from skin as much as possible
• D. Expose EMA to direct sunlight for faster curing

Answer: (C)

When working with EMA, the priority is to prevent skin contact because the monomer can irritate and sensitize the skin. Keeping the monomer away from skin as much as possible minimizes the risk of dermatitis and allergic reactions. In practice, this means using gloves and appropriate tools to handle the product, working in a well-ventilated area, and cleaning up any splashes promptly. Direct sunlight is not a reliable or safe method to cure or speed up EMA, and exposure to UV or heat can cause unpredictable effects; wearing no protective gear is unsafe, and applying EMA directly to the skin to test for reaction is hazardous and not a recommended safety procedure. So, minimizing skin contact with EMA is the safest and most practical safety practice.
