Final answer:
To indicate a person diving from a boat, standard safety signals should be used, and it's important to be aware of the surroundings and obey 'no diving' signs to prevent injuries.
Step-by-step explanation:
To indicate that a person is diving from a boat, you should be aware of the standard safety signals and practices. Contrary to the myth, someone who is drowning may not be able to shout for help or wave their arms; they might be unable to draw attention as they struggle.
When it comes to safety while diving, it's crucial to use proper techniques and obey any posted signs, such as 'no diving' warnings, to avoid the risk of injury.
Diving in shallow water can cause serious injuries to your nervous system, so always check the depth and ensure it is safe before diving. Also, remember that a person's body language and actions in the water can be dramatically different from what is expected, so always maintain clear communication and safety protocols at all times.
To indicate a person is diving from a boat, use a diving hand gesture. This gesture involves diving your hand with your fingers first into the water. It represents a swimmer doing a dive. By performing this gesture, the swimmer can show that they are diving from a boat.
