What characteristic should the exterior lens of lights in a buffer room have?

The correct characteristic for the exterior lens of lights in a buffer room is a smooth, mounted flush and sealed design. This feature is critical in a sterile compounding environment for several reasons.

First, a smooth surface is essential to prevent any dust, particulate matter, or microbial contamination from accumulating on the light fixture. A rough or textured surface may trap particles and make cleaning more difficult, potentially compromising the sterility of the area.

Additionally, being mounted flush ensures that there are no gaps or crevices where contaminants can hide or accumulate. Sealing the light fixtures is equally important, as it prevents the ingress of air and possible contaminants from the outside environment into the sterile compounding space.

Together, these characteristics enhance the cleanliness and safety of the buffer room, which is vital for maintaining the integrity of compounded sterile preparations.
