In the tb 99 - river rescue, when is special protective gear required?

Explanation:

Special protective gear is required in the following two cases:

Firstly, when rescuing a victim from fast-flowing water, special protective gear is necessary due to the increased risks posed by the swift currents. The velocity of the water creates a higher potential for both the rescuer and the victim to sustain injuries. The strong currents can make it difficult to maintain control and navigate effectively. Hence, specialized gear such as swiftwater rescue suits and helmets is essential to provide adequate protection and enhance the rescuer's ability to maneuver in fast-flowing waters.

Secondly, when dealing with rescuing a victim from icy water, special protective gear becomes crucial to mitigating the risks associated with cold temperatures. Cold water can lead to hypothermia and decrease muscle function, making it even more challenging for both the rescuer and the victim. In such scenarios, specialized gear designed for cold-water rescues, such as drysuits and thermal insulation, is essential. This gear helps prevent the rescuers from suffering the harsh effects of the cold environment while ensuring flexibility and buoyancy during the rescue operation.
