What technique should be used when multiple people fall into cold water?

The Huddle technique is the appropriate choice for situations where multiple individuals have fallen into cold water. This technique involves the individuals grouping together closely in a huddle, which helps to conserve body heat and reduces the risk of hypothermia. By maintaining physical contact, the group can share warmth, which is vital in cold water scenarios where body temperature can quickly drop.

In addition to heat conservation, the Huddle technique also provides emotional support and reassurance to those in distress, which can be crucial in a high-stress situation like being in cold water. The collective buoyancy of the group can also assist in staying afloat and maintaining a safer position in the water.

Other techniques mentioned, such as the Pool or Group techniques, may not effectively address the immediate concern of heat loss in cold water or provide the same level of buoyancy and support during a critical situation. Thus, the Huddle technique stands out as the most effective strategy in this context.
