Now that you are hopefully concerned and are aware of the dangers of primary search, let’s bring some structure into the problem we are trying to solve.
In my method I give clear and usable definitions to all the terms we use. Earlier we have already defined the primary search itself and have given a practical problem definition of primary search so that we can select search methods based on their objective merit, not somebody's beliefs and preferences. We have also defined the types of primary search so that we have right tools for every job. We will later dive into each type of search and break it down, systematically again, into components, making a complex problem simpler. Then I will show you the best algorithms for each of the components.
Please don't be afraid when you hear this word – algorithm. It is simply a set of rules that determines what we do while searching, nothing more. In modern firefighting you need to use these rules to survive. "Just jumping in" is no longer safe (and never was, to be frank, and ever growing list of NIOSH LODD reports is all the proof that you need).
In addition to a well-structured study material, the tested navigation algorithms that we use also lead to more systematic, predictable and efficient search trajectories inside of the building. We do complete opposite of a random search that relies on sheer luck. By doing so, we maximize the number of lives saved and increase the chances of survival for both civilians and ourselves.
Please worry not – you won’t have to do any math, I have done it for you. I will give you simple, yet efficient rules for navigation that work in the worst conditions, under the combat stress of modern firefighting.
