What describes the blast snorkel clear?

• A. A slow inhale to fill the lungs and push water out
• B. A quick shoulder shrug
• C. A deep dive with mouth closed
• D. A forceful exhale to blow water out of the snorkel

Answer: (D)

Clearing a flooded snorkel is about using a blast to expel the water. By exhaling forcefully through the snorkel, you push the water up and out of the tube so air can flow again into the mouthpiece. A slow inhale won’t push water out, a quick shoulder shrug doesn’t generate the needed pressure, and a deep dive with the mouth closed prevents any air from traveling up the snorkel to clear it. The blast clear works because the sudden exhaled air creates enough pressure to blow the water out and restore normal breathing through the snorkel.
