Answer:
B. Raft Construction
Read Explanation:
Raft construction is an excellent example of an "improvised water rescue aid" because it involves using readily available, everyday materials to create a functional flotation device.
The Principle of Improvised Raft Construction
The core idea is to leverage the buoyancy of common objects to create a makeshift raft that can support a person's weight and keep them afloat in a rescue situation. In a flood or other water-related disaster, professional rescue boats may not be immediately available, making this a critical life-saving skill.
Common Materials: An improvised raft can be made from a variety of buoyant materials, such as empty plastic bottles, inflated tires, logs, bamboo, or even just bundles of dry clothing or plastic bags filled with air.
Assembly: These materials are then lashed or tied together using whatever is at hand, like rope, vines, or torn strips of cloth, to form a stable platform.
Purpose: The primary purpose of such a raft is to provide a way for people to stay above the floodwaters, either to be transported to safety or to use as a stable platform for a rescuer to reach them. This simple, life-saving technique can turn ordinary household items into essential rescue equipment during an emergency.
