Temporary refuge areas (TRA) assist firefighters from radiant heat when the flame front has caught up to emergency workers. When lookouts, anchors, communications and escape routes have failed and safety zone is too far away a TRA might still save the team. A temporary refuge area is used as a last-resort survival option when sudden changes in fire behavior prevent firefighters from reaching a planned escape route or safety zone. Unlike an ideal safety zone—which is an area clear of flammable materials where you can survive the passing fire without a fire shelter—a temporary refuge provides emergency shelter to shield you from radiant heat. Here are the primary options and characteristics for a temporary refuge: Structures:  If you must use a building, prepare it rapidly by clearing away outside combustibles, closing all windows and heavy drapes, and bringing charged hoses and fire extinguishers inside. Once inside, stay on the main floor and keep away from windows, basements, and ...

What is Structural Triage?  During a wildfire,  structural triage  is the rapid assessment process firefighters use to decide which homes can be safely and effectively defended. Because resources are limited and life safety is the top priority, firefighters categorize structures into a few main groups: Standalone / Not Threatened:  The property has a good "safety zone" and clear defensible space. It has very few tactical challenges and will likely survive the fire front with little to no active firefighter intervention. Defensible (Prep and Hold):  The home is threatened by the fire, but it has a safety zone. Firefighters can safely stay on-site to prep the structure and actively defend it as the fire passes. Non-Defensible (Prep and Leave / Rescue Driveby):  The property lacks a safety zone, is surrounded by heavy fuels, or has serious hazards. It is simply  too dangerous  for firefighters to stay. If time permits, crews will quickly do a rescue ...
