- The document discusses various methods of fire suppression and control, including structure fires, vehicle fires, ground cover fires, and other exterior fires. It addresses factors to consider such as fire behavior, safety, tactics, equipment used, and more. - Firefighters must evaluate various factors to select the appropriate suppression strategy, whether offensive interior attack or defensive exterior isolation. Resource coordination and controlling utilities are also important. - Proper PPE and safety guidelines must be followed for all fire types, especially those with electrical, chemical, or other hazards like Class C, D, or alternative fuel vehicle fires. Direct, indirect and combination methods can be used depending on the situation.
