When is the survival rate typically higher during a fire rescue operation?

The survival rate is typically higher during a fire rescue operation pre knockdown because this phase occurs before the fire has been effectively suppressed. At this stage, individuals who are in distress can still be located and extracted from danger, often before smoke and flames have compromised their safety and ability to escape.

Focusing on the time frame of "pre knockdown," it serves as a crucial opportunity to reach and save individuals who may still be alive and capable of being rescued, thus maximizing the chances for survival. Once suppression efforts begin, conditions often change rapidly; temperatures rise, visibility decreases due to smoke, and fire behavior can become erratic, making rescues more perilous and complicated. This makes the pre-knockdown phase vital for personnel to navigate through smoke and low visibility to secure saved lives.

In contrast, other time frames like during the fire are inherently dangerous and usually result in lower survival rates due to immediate threats from flames and smoke inhalation. Post knockdown may also lead to a higher chance of survival but is contingent upon successful suppression of the fire, which may not always guarantee immediate safety for those trapped. Similarly, after evacuation typically pertains to individuals who have already escaped, thus not reflecting the operational aspect of a fire rescue that prioritizes timely
