Firefighter Girls

Some fire fighting tactics may appear to be destructive, but often serve specific needs. For example, during "ventilation" firefighters are often forced to open holes in the roof or floors of a structure (called "vertical ventilation") or open windows or walls (called "horizontal ventilation") to remove smoke and heated gases from the interior of the structure. Such ventilation methods are also used to locate victims quicker as visibility increases and to help preserve the life of trapped or unconscious individuals due to the poisonous gases inside of the structure. Vertical ventilation is absolutely vital to firefighter safety in the event of a flashover or backdraft scenario. Releasing the flammable gasses through the roof often eliminates the possibility of a backdraft and by the removal of heat the possibility of a flashover is reduced significantly. Flashovers, due to their intense heat (900–1200° Fahrenheit) and explosive temperaments are almost always fatal to firefighter personnel. Precautionary methods, such as busting a window out, often reveal backdraft situations before the firefighter enters the structure and is met with the circumstance head-on. Firefighter safety is the number one priority.
Whenever possible, movable property is moved into the middle of a room and covered with a heavy cloth tarp (a "salvage cover"). Other steps may be taken to divert or remove fire flow runoff (thus salvaging property by avoiding unnecessary damage), retrieving/protecting valuables found during suppression or overhaul, and boarding windows, roofs and doors against the elements and looters.
• HAZMAT
Firefighters in the United States are frequently the first responders to HAZMAT incidents. The Occupational Safety and Health Administration standard 1910.120 defines four standards of training First responder awareness level, First responder operations level, Hazardous materials technician, and Hazardous materials specialist. EMS-based paramedics are typically trained to the awareness level, whereas career and volunteer firefighters are often trained to the operations level or better. Other nations have trained only elite firefighters and rescuers to do HAZMAT so that funding and equipment could go to fewer stations. This gives departments elite HAZMAT personnel and high-grade equipment for an incident. Departments place these companies in stations where they can be very mobile.
