Safety Management


■Problems During Your Course

If, by chance, you should suddenly feel unwell or experience other problems, immediately signal your instructor who will help you and if needed, stop the skin dive.


Safety first



■Buddy System

Always go skin diving with at least a dive buddy, if not in a group of three. Never go alone. This is called the buddy system. By going together, you can watch out for each other and enjoy the ocean safely.



■Skin Diving Point Selection

Wind and current have a great influence on the areas where we skin dive. When conditions are good for surfing, they are poor for skin diving. Calm waters are best. Since ocean conditions are fluid, it is best to have a backup point selected in case winds and currents are not advantageous to skin diving.

Calm waters are best



Waves have their origins primarily in wind, and while there may be no wind blowing near the coast, there may be winds blowing in the open sea which can cause high waves to break on the shore. As well, as waves approach the shore, they collapse, causing undertow and rip currents. In this region - the surf zone – it is easy to have your feet pulled out from under you, especially with all your equipment on, so caution is required.
Especially for beginners it is highly recommended you choose your skin diving point in consultation with your instructor.

■Dangerous Skin Diving Points

Winds that follow lengthy, unbroken coastlines create long shore currents. So far as shallows exist near the shore, undertows are created, and at breaks in the shallows, strong rip currents are created. As well, where there are groupings of large rocks, complex water channels are created which require caution.

■Stopping or Changing Your Plans

There are times when we need to change our plans due weather or ocean conditions. Safety must be your first concern, so when conditions are unsafe, you need to stop your skin dive. It’s a good idea to always have alternatives in mind.


When ocean conditions are poor, cancel the dive.



■Emergency Plan

To deal with emergencies that can occur during your skin dive, we plan for them in advance.
As well, we prepare emergency contact information and equipment and familiarize ourselves with local emergency services.
We should always have a first aid kit at the ready.
