What is meant by "funnel search" in a rescue operation?

In a rescue operation, "funnel search" refers to the strategy of narrowing down search areas based on observable indicators, such as smoke and heat patterns. This method involves analyzing the environment to determine where victims are most likely to be located, based on the behavior of smoke, the spread of heat, and other clues provided by the situation. By focusing efforts on these high-probability areas rather than conducting searches in a random manner, rescuers can use their resources more effectively and increase the chances of locating victims quickly.

This approach is grounded in the principles of fire dynamics and can aid teams in making informed decisions about where to search first. Understanding the flow of smoke and the areas that are most affected by fire informs teams about potential locations where victims might be trapped. Thus, this method enhances the efficiency of the rescue operation while prioritizing safety and effectiveness.
