Final answer:
The first step if you observe panic in a diver is to ensure positive buoyancy by having them fill their BC and then call for help. Remain calm and do not drop your weight belt, as personal safety is important. Further assistance may include removing the diver's weight belt once buoyancy and help have been established.
Step-by-step explanation:
If you observe signs of panic in a diver at the surface, the first step should be to establish positive buoyancy for both the rescuer and the panicked diver. This can typically be done by instructing the panicked diver to fill their buoyancy compensator (BC), which helps prevent them from sinking and reduces the immediate danger.
The second step is to call for help to alert others to the situation and ensure that assistance will be on the way. While approaching the diver, it's important to remain calm and reassuring to help stabilize the situation.
When approaching a panicked diver, it is crucial not to drop your own weight belt, as this can compromise your own safety. It is also generally advised not to attempt to remove the diver's weight belt immediately, as this can be dangerous if not done correctly.
After establishing buoyancy and calling for help, you can then safely assess the situation and provide further assistance as needed, which may include helping the diver to remove their weight belt in a controlled manner if necessary.
