In an emergency, if you must jump from a MODU, what is the best procedure to follow?

Correct Answer: Option B — holding down the life preserver against the chest with one arm crossing the other, covering the mouth and nose with a hand, and feet together

Proper jumping technique requires holding the life preserver firmly against the chest to prevent it from striking the chin or face upon water impact. Crossing arms and covering the nose/mouth prevents injury and water inhalation, while keeping feet together maintains stability and minimizes the impact force on the body.
