Which SAR component connects to the face piece via a low-pressure hose?

• A. harness mounted regulator
• B. small, reserve cylinder
• C. conventional face piece with no hoses
• D. low pressure hose connected to a conventional face piece

Answer: (D)

Air to the face piece is delivered through a low-pressure hose. The component described as a low-pressure hose connected to a conventional face piece is the direct link that carries the regulated air from the regulator to the face piece, enabling the wearer to breathe. In other setups, the regulator is the source and would connect to the hose, but the wording here points to the hose–face piece connection itself. The other choices either describe equipment that isn’t the direct link to the face piece, or a face piece without hoses, which wouldn’t provide breathing air.
