Firefighting – Transitional attack – How, when and why?
In this presentation I explain how a transitional attack should be performed, when to use it and why.
Firefighter autonomy: Critical for incident command
With predetermined goals and frameworks for firefighter actions, we can achieve effective incident command at arrival to fires.
GPM vs BTU = FALSE
A fires total heat release rate is not a good value for how much water flow that is needed for suppression, and simplified statements are misleading.
Firefighter TIC – Different positions show different temperatures
A firefighter thermal imager camera is a poor thermometer, but a vital tool for firefighting. Learn more with this video example and explanation.
Smoke cooling’s limited impact on the fire compartment
Video showing the limited influence of smoke cooling methods on fire compartment and the quick reheat experienced by advancing firefighters.
Improve TIC image: Keep low and clean lens during firefighting
Stay low and keep the thermal imager camera low. Clean the lens with wipes to restore image quality during firefighting – Video example.
Firefighting training: Competency is the main priority, not safety
Prioritizing competency over safety is vital in firefighting training. Safety becomes a byproduct of doing the right thing in the right time.
Straight streams for smoke cooling, what is missing?
Lars Axelsson shows how straight streams cool smoke and what the missing research and teaching pieces are for understanding it better.
Negative pressure in fire compartment at suppression
When water turns to steam it expands. When smoke cools down it contracts. The resulting pressure will affect the potential for rescues at fires.
Dry air is heavier than wet air – Stay low
Steam from fires and fire suppression contain lots of energy and blocks our vision. Stay low to avoid the rising steam inside the compartment.
