The manual inflation tube on the inflatable PFD is used to inflate the PFD manually.

• A. True
• B. False
• C. Not Applicable
• D. Sometimes

Answer: (A)

The main idea here is that inflatable PFDs are built with more than one way to fill them. In addition to the CO2 canister that automatically inflates the bladder when activated, there is a manual inflation tube that lets you inflate the PFD by mouth. This tube is a backup method so you can ensure the vest is fully buoyant if the canister doesn’t deploy or if you need to add extra inflation. That’s why the statement is true: the manual inflation tube is indeed used to inflate the PFD manually.
