Which component is essential to provide a seal and protect the wearer's eyes and respiratory tract?

Explanation:
The facepiece is the part that both seals to your face and protects your eyes and respiratory tract. It sits against the skin with a tight seal created by the facepiece and its straps, keeping contaminants like smoke and particulates from entering and making sure the air you breathe comes through the respirator. It also provides eye protection via the built-in visor or protective eye area. The nose cup lives inside to help with fit and fog control, but it doesn’t form the primary seal. The voice box is for communication, and the manifold handles air delivery—neither of these creates the necessary facial seal or eye protection.
