The First-Due: Upon arrival when sizing-up and looking at the building(s) and occupancy, past operational experiences (both good and bad) give the officer and company experiences that define and determine how we further assess, react and expect similar structures and occupancies to perform at a given alarm.
The theory of naturalistic decision-making forms much of this basis and translates into assignments and implemented actions.
The Art and Science of Firefighting is predicated on a fundamental understanding of how fire affects a building, the compartment and its occupants; and the manner in which the companies engage upon arrival and transition into combat fire suppression at a structure fire.
We predicate with certain expectations that fire will travel in a defined (predictable) manner;
- That the building will react and perform under assumptions of past performance and outcomes,
- That fire will hold within a room and compartment for a predictable given duration of time;
- That the fire load package and related fire flows required will be appropriate for an expected size and severity of fire encountered within a given building, occupancy and structural system,
- And given an appropriately trained and skilled staff to perform the requisite evolutions; we can safely and effectively mitigate a structural fire situation in any given building type and occupancy.
- We assume we will have the adequacy of time to conduct and employ the required tasks identified to be of importance based upon identified or assumed indicators;
- That the building will conform to the rules of firefighting engagement
