Purging the air up and out of an immersion suit is called:

• A. Burping the suit
• B. Venting the suit
• C. Inflating the suit
• D. Deflating the suit

Answer: (A)

Purging air from an immersion suit is all about removing trapped air to control buoyancy and fit. The common term for this deliberate release of air upward and out of the suit is “burping the suit.” When air is trapped inside, it makes the suit buoyant and bulky, which can hinder movement and make it harder to stay oriented. By applying gentle pressure or moving in a way that shifts air toward the neck or purge outlets, the air is expelled, reducing buoyancy and helping the suit sit more comfortably and predictably on the body.

So, burping the suit is the best way to describe this air-release action. The other terms refer to different ideas: venting is a general release of air and water pressure, inflating would add air, and deflating would remove air but doesn’t capture the specific upward purging process used to clear air pockets in the suit.
