Which component of SCBA provides both respiratory and eye protection?

The full-face piece of the SCBA is designed to provide comprehensive respiratory protection and also safeguard the eyes. This component creates a sealed environment around the face, ensuring that inhaled air is filtered and free from harmful gases, particulates, and other contaminants present in hazardous environments. Additionally, the full-face piece includes a visor or lens that protects the eyes from chemical splashes, smoke, or flying debris. By covering both the mouth, nose, and eyes, the full-face piece is essential for ensuring the user's safety in toxic or low-visibility situations. This dual functionality reinforces the necessity of this component in a self-contained breathing apparatus.
