Final answer:
To assist a person motionless in the water, first ensure your own safety, then remove them from water and administer CPR on stable ground. Be aware of signs that prohibit diving and recognize signs of drowning, such as low head position and uncontrolled limb movements. If unable to help, notify an adult or authority figure immediately.
Step-by-step explanation:
When you notice a person motionless in the water, it is critical to act swiftly and follow the proper rescue protocol to ensure the person's safety. The first step is to ensure your own safety and assess the situation without endangering yourself.
If the person is in immediate danger and you are trained, proceed to remove the person from the water safely. Always remember that performing CPR on someone while still in the water is not effective; the person must be brought to stable ground first before administering CPR.
Additionally, be mindful of any signs indicating "no diving" to prevent injuries, and understand that often a drowning person cannot shout or signal for help due to a muscular spasm that seals their airway, making it important to recognize other signs of drowning such as their head being low in the water and having uncontrolled arm and leg movements.
If you are not able to help, it is essential to notify an adult or authority figure to get professional assistance. By understanding the difference between drowning myths and realities, and observing your surroundings, you can be better prepared to help someone in need without compromising your own safety.
