Fire Suppression and Emergency Response
Fire Suppression and Emergency Response tests how you apply fire behavior, incident command, hose streams, ventilation, and tactical priorities to a structure fire. Houston's mix of wood-frame apartments, strip centers, and older commercial buildings makes size-up and coordinated ventilation especially testable.
Core rules and concepts
- The fire tetrahedron is fuel, oxygen, heat, and chemical chain reaction. Extinguishment removes one side: cool with water, smother, separate fuel, or interrupt the chain reaction.
- Incident priorities are life safety, incident stabilization, and property conservation, in that order.
- RECEO-VS is a tactical framework: Rescue, Exposures, Confinement, Extinguishment, Overhaul, Ventilation, Salvage. The order flexes; ventilation may happen early only when coordinated with a charged line.
- A 360-degree size-up considers construction, occupancy, fire location, smoke condition, life hazard, access, and water supply.
- Choose a solid or straight stream for reach and penetration; a fog stream is for protection or hydraulic ventilation and can push fire if misused.
- Apply water to the seat of the fire, not into smoke. Use short pulses and watch for steam conversion and visibility.
Worked example
Dispatch: two-story garden apartment, smoke from a second-floor window, one trapped child. First-arriving engine should announce arrival, establish command, and complete a 360. The line is stretched to the interior stairs and charged before entry. A primary search proceeds with a thermal imager behind the nozzle. A ground ladder goes to the child's window as an alternate rescue route. Horizontal ventilation occurs after the line is ready and the entry team is in position. Reasoning: life safety drives the search and ladder; confinement keeps fire off the stairs; coordinated ventilation avoids feeding fire before water is on it.
Traps that cost marks
- Venting before a charged line is at the door.
- Flowing fog into smoke from outside and calling it an attack.
- Searching past the fire without a protecting line.
- Using an elevator or skipping the 360.
- Forgetting to announce command or request a PAR.
