The continuous flow mask ___________ provide protection for smoke inhalation.

The continuous flow mask ___________ provide protection for smoke inhalation.

• A. Does not
• B. Does
• C. Will not
• D. Could

Answer: (A)

The key idea is that protecting against smoke inhalation requires filtering the air and a sealed breathing path, not just supplying oxygen. A continuous flow mask delivers a constant flow of oxygen to the mask, but it has no filtration and does not seal against smoke or remove toxic gases. So while it helps maintain oxygen levels, it does not protect you from inhaling smoke. In a smoke-filled environment, true protection comes from equipment designed to filter air and provide a sealed supply, such as a smoke hood or a proper respirator, not from a simple continuous flow oxygen mask.
