After planning has been made, the dive leader should meet with all stakeholders.

If you are diving with a dive center, the dive leader must identify himself, like the entire team (Master, Sailor and other members), identify the locations to equip, assemble and disassembly equipment, means and transport procedures to the dive site, number of divers of the group, among other information.

Internationally the information of the dive briefing should be organized in 5 areas:

Segurance , Explication , Equipamentos , Discipline , Sinais

1. SAFETY

---

In the safety topic the dive leader should refer to the location of emergency equipment (on land or on the vessel) such as the oxygen kit, define the person responsible for carrying out the aid request (telephone contact), inform about the safety and emergency plan, such as referring how to proceed in the event of a diving accident, if the dive exit is carried out using a vessel, you must explain the safety rules on board, inlet and exit of the water, among other relevant information.

Some procedures are important to remember divers:

• Controlled descent
• Separation of diving companion
• Shortness of breath or low pressure
• Emergency ascent
• Surface emergency
• Controlled climb with safety stop

2. Explanation

---

The following aspects should be addressed in the explanation:

• Environmental factors at the dive site
  • Surface (Temperature, Currents, Ripple, Wind)
  • Underwater (Tides, Background Type, Visibility)

• Description of dive site
  • Fund Type
  • Fauna and Flora
  • Reference Points
  • Points of Interest
  • Underwater Route
  • Dangers

3. EQUIPMENT

---

Check whether the equipment used by each diver is suitable for diving and that everyone knows how to use it correctly (vest, compass, landing buoy, etc.).

Before starting the dived each diver must do the check of his companion. This is what we might call the FAP check :

1. Flutuability
2. Ar
3. Precintas

1. Buoyancy

• Starting with the vest, check the operation of the intake hose, trachea and purge valves.
• The ballast system should also be checked to confirm that you have the ideal weight for the dive that will take place, and that it is in perfect condition (fitting system or belt with buckle).

2nd Air

• Then check that the bottle is open.
• What air pressure is indicated on the pressure gauge.
• The flow of regulators (main and octopus).
• The existence of leaks (replacement of the toric joint).
• The condition of the hoses.

3. Straps

• Then check that the bottle is securely fixed to the vest.
• Whether all the straps of the vest are adjusted and what other types of fasteners are used.
• If the mask straps and fins are in good condition.
• What kind of mechanism to release the ballast system.
• If the instruments are properly positioned and safe.

DURING THE CHECKING OF THE EQUIPMENT, THE EVALUATION OF THE DISPOSAL OF THE DIVE COMPANION IS ESSENTIAL FOR THE DIVE TO TAKE PLACE IN THE BEST CONDITIONS, BECAUSE IN THIS PHASE IT CAN STILL BE CHANGED THE PLANNING OR EVEN NOT TO PERFORM THE DIVE, ACCORDING TO ITS PHYSICAL OR EMOTIONAL STATE

4. DISCIPLINE

---

The discipline is an area where all information and procedures related to the dive profile should be addressed, such as:

• Maximum Depth.
• Return and reserve pressure.
• Ascent (Cable or buoy landing).
• Ascent speed.
• Security stop.
• Position of each diver in the group.
• Warning of the dive companion “half bottle” (50% of the initial pressure).
• Pressure for ascent or maximum dive duration.
• Reserve pressure (50bar).

5. SIGNS

---

Recall conventional signals and/or combine new signals, where appropriate.
