Free Diving

Freedive Safely

  1. Dive with an evenly matched buddy, and conform to the level of the least capable diver.
  2. Weight yourself correctly (positively buoyant at surface) even after exhalation.
  3. Do not hyperventilate to excess.
  4. One up/ One down – diving with constant visual contact. When conditions allow each diver should have a flag.
  5. Maintain close, direct supervision of any freediver for no less than 30 seconds after he surfaces.
  6. Make your minimum surface interval twice the duration of your dive time.
  7. Do not take every dive to its limit. Maintain a reserve.
  8. Review, practice and discuss how to recognize and handle blackouts and near blackouts.

Rescue Skills

  1. Get victim to surface immediately. Establish positive buoyancy for the both of you.
  2. For a witnessed blackout; remove mask and snorkel, blow on face-eyes, stimulate face with a few taps, vocalize encouragement to breathe, otherwise open the airway and begin immediate rescue breathing. 1 breath every 5 seconds
  3. Get victim to land or boat ASAP, manage ABCDs (airway-breathing-circulation-deadly bleeding) start CPR with O2, 30 compressions to 2 ventilations, as needed.
  4. If evacuation from water is prolonged, monitor Airway & Breathing and provide rescue breathing (1 breath every 5 sec.) during transport if needed.
  5. Seek help from EMS (emergency medical services) 911, or hail the Coast Guard on Channel 16 on VHF radio.
  6. After a SWB, STOP diving and immediately seek medical evaluation.
