Which component is described as a clear safety plastic element mounted in a flexible rubber frame?

• A. Nose cup
• B. Exhalation valve
• C. Facepiece lens
• D. Speaking diaphragm

Answer: (C)

Identifying respirator facepiece components: the clear safety plastic element mounted in a flexible rubber frame is the facepiece lens. This part provides visibility while the mask stays sealed to the face, typically made from impact-resistant plastic such as polycarbonate and designed to stay clear and durable under use. It sits within the flexible rubber frame so the lens moves with the mask and maintains the seal around the eyes. The other parts have different roles: the nose cup forms the nasal seal, the exhalation valve vents breath, and the speaking diaphragm aids voice transmission.
