How do you put the Liquide PBE on?

• A. With the front of the PBE facing your body, open neck seal and lower it down over head back to front until it fits securely around neck; hair tucked inside; hood donned within 8 seconds of opening.
• B. Place hood over head and fasten neck seal.
• C. Don by pulling from the back of head.
• D. Only when instructed.

Answer: (B)

Donning the Liquide PBE correctly centers on creating a secure barrier around the neck so breathable air is delivered where you need it. The simplest and most reliable way is to place the hood over your head and fasten the neck seal. This establishes an immediate, snug seal that prevents outside air from leaking in and ensures the PBE can do its job without delay. It’s a straightforward action you can do quickly in an emergency, and it minimizes the chance that hair or clothing will interfere with the seal. The other approaches introduce extra steps or positions that can delay readiness or risk misalignment, which could compromise the seal. After placing the hood, check that the neck seal is firmly closed and comfortable to maintain a reliable fit.
