What safety consideration is essential when using alcohol-based skin prep?

• A. It should be diluted with water before use
• B. It is safe to apply near mucous membranes
• C. It is nonflammable
• D. It is flammable; allow to dry completely and keep away from flames or heat sources

Answer: (B)

Alcohol-based skin prep is highly flammable, so the essential safety step is to let it dry completely and keep it away from flames, sparks, and any heat source during and after application. This prevents ignition of vapors in the surgical area. Use on intact skin as directed and follow product guidelines about any cautions regarding mucous membranes or sensitive tissues.
