Course Outline

After the dive, follow these safe practices:

  • Protect yourself from heat loss by wearing adequate clothing.
  • Never try to carry out in-water decompression in the event of suspected decompression illness. There is a better-than-even chance doing so will worsen rather than improve the situation.
  • Avoid exertion.
  • Never underestimate the appearance, even if late onset, of any symptom following a dive, and call your local diving or emergency services to evaluate the situation.
  • Avoid flying or driving to altitudes greater than 300 meters/1,000 feet after diving. Both of these actions take you to lower air pressure than sea level, which can be dangerous if you have not allowed adequate surface intervals. Follow safe diving recommendations to wait at least 12 hours after a single no-stop dive and at least 24 hours after repetitive diving or decompression diving.
