Safety guides for snorkeling & diving in Jellyfish season

You should not stay bared body while snorkeling & diving to protect yourself from poisoned creatures in general or jellyfish in particular, wear protective clothing: a long-sleeve shirt and swimming trouser will be the best to protect yourself, keep body warm and minimize the use of sun cream which is harmful to coral as well as useless as the wave will take it away.

Always look around especially stay away from the moving currents as jellyfish can come just after few second when you dont pay attention to surrounding things.

Treatment for most jellyfish sting

There are some jellyfish, include box jellyfish and Irukandji that are dangerous and require emergency first aid.

  1. Rinse the area with vinegar, for at least 30 seconds. If you don’t have vinegar, use sea water.
  2. Remove tentacles from the skin with tweezers (Be careful not to rub the sting area or to get sand into the sting)
  3. Once the tentacles are removed, soak the area in hot but not scalding water for 20 to 45 minutes.
  4. If hot water is not available, apply a cold pack to help the pain. Don’t apply ice directly to unprotected skin.
  5. If there are any signs of respiratory distress, go as quick as possible to the nearest hospital.

On OnBird’s snorkeling trip we always prepare vinegar for jellyfish-related emergency cases.
