Firefighting and Fire Suppression

Firefighting is the direct attack on active fires in structures, vehicles, and wildlands using water, foam, hoses, ladders, and ventilation to remove heat, smoke, and oxygen from the fire. A firefighter must understand fire physics, hose deployment, ladder safety, and rescue techniques — and execute all of it under extreme stress, darkness, and heat while wearing 75 pounds of protective gear. Firefighting is the tactical deployment of water, foam, and agents to extinguish fires while simultaneously locating and rescuing trapped occupants. Firefighters operate in extreme environments: temperatures above 1000°F, zero visibility from smoke, structural collapse risk, and hazardous materials. The firefighter uses ground and aerial ladders to access upper floors, charged hoses to apply water or foam to the fire, thermal imaging to locate occupants and hotspots, ventilation (roof cuts, window breaks) to release smoke and heat, and search-and-rescue techniques (low-crawl, hand contact with walls, accountability with crew) to navigate and save lives.
