Firefighter Girls

• Fire control
Fire control (or fire fighting) consists of depriving a fire of fuel (Reducing Agent), oxygen (Oxidizing Agent), heat and/or the chemical chain reaction that are necessary to sustain itself or re-kindle (also known as the four components of the fire tetrahedron). Firefighters are equipped with a wide variety of equipment to accomplish this task. Some of their tools include ladder trucks, pumper trucks, tanker trucks, fire hose, and fire extinguishers. Very frequent training and refresher training is required.
Structure fires may be attacked, generally, either by "interior" or "exterior" resources, or both. Interior crews, using the "two-in, two out" rule, may advance hose lines inside the building, find the fire and cool it with water. Exterior crews may direct water into windows or other openings, or against other nearby fuels exposed to the initial fire. A proper command structure will plan and coordinate the various teams and equipment to safely execute each tactic.
