Coordination When Suppressing Structure Fires • Fire attack on burning structure must be coordinated • When fighting any fire, firefighters should always work as a team under direction of a supervisor Firefighter I 11

Actions to Take • Advancing hoseline teams should carry equipment needed to perform a variety of tasks • Certain equipment carried by teams advancing hoselines • Person at nozzle has responsibilities before entering building/area (Continued) Firefighter I 12

Actions to Take • When structure/major contents are involved in fire, firefighters should wait at entrance, staying low, out of doorway until fire officer gives order to advance • Before entry, extinguish fires showing in exterior overhangs/around entry or egress points (Continued) Firefighter I 13

Actions to Take • Whenever possible, approach and attack fire from unburned side to keep it from spreading throughout structure • Once fire is contained, determine area of origin, protect evidence before overhaul and extinguishment (Continued) Firefighter I 14

Actions to Take • Breathing apparatus must be worn during overhaul, extinguishment • Valuables found during overhaul should be turned in to supervisor Firefighter I 15

Pre-Entry Considerations • Conduct quick size-up • Maintain high level of situation awareness • Read fire behavior indicators • Understand crew’s tactical assignment (Continued) Firefighter I 16

Pre-Entry Considerations • Identify potential emergency escape routes • Assess forcible entry requirements • Identify hazards • Verify that radios are working, on right channel, being received Firefighter I 17

Opening Doors • If door to fire area must be opened, all members should stay low and to one side of doorway • Check door for heat before opening Firefighter I 18

Gas Cooling • Not a fire extinguishment method; way of reducing hazard presented by hot gas layer • Effective when faced with shielded fire Firefighter I 19

Hot Gas Layer • Hot gas layer accumulating in upper levels of compartment presents problems • Cooling hot gas layer mitigates hazards by slowing transfer of heat to other combustibles Firefighter I 20

Cooling Hot Gas Layer • Apply short pulses of water fog onto it • Repeat technique as necessary while hose team advances under gas layer toward fire Firefighter I 21

Direct Attack • Most efficient use of water on freeburning fires made by direct attack (Continued) Firefighter I 22

Direct Attack • Usually from straight or solid stream • Techniques • Water should not be applied long enough to upset thermal layering Firefighter I 23

Indirect Attack • Used when firefighters unable to enter burning building/ compartment • Can be made from outside compartment through window or other small opening Courtesy of Dick Giles (Continued) Firefighter I 24

Indirect Attack • Not ideal method of attack where building occupants may still be inside • May be only method of attack until temperatures reduced • Procedures for making indirect attack Firefighter I 25

Combination Attack Uses heat-absorbing technique of cooling hot gas layer followed by heat-reducing direct attack on materials burning near floor level Firefighter I 26

Master Streams • Usually deployed in situations where fire is beyond effectiveness of handlines or there is need for fire streams in areas that are unsafe for firefighters • Main uses for master stream Firefighter I 27

Positioning Master Stream • Must be properly positioned to apply effective master stream on fire • Master stream can be adjusted up, down and left, right • Once line in operation, must be shut down if device is to be moved (Continued) Firefighter I 28

Positioning Master Stream • Stream should be aimed so it enters structure at upward angle, deflects off ceiling or other overhead objects (Continued) Firefighter I 29

Positioning Master Stream • Desirable to place master stream device in location that allows stream to cover most surface area of building Firefighter I 30

Supplying Master Streams • Master stream devices can have high friction loss in supply hose • Because master stream devices used primarily in defensive fire fighting, desirable to shut down handlines to keep from reducing water supply available for master streams (Continued) Firefighter I 31

Supplying Master Streams • Always follow SOPs in operation of master streams, handlines Firefighter I 32

Staffing Master Stream Devices • Usually takes minimum of two firefighters to deploy master stream device, supply water to it • Once portable master stream device in place, can be operated by one firefighter (Continued) Firefighter I 33

Staffing Master Stream Devices • Some situations may be too dangerous to have firefighters stationed at master stream device Firefighter I 34

Standard Fire Fighting Orders When Fighting Wildland Fires • Maintain control of forces at all times • Fight fire aggressively, providing for safety first Firefighter I 117

Summary • Attacking fires early in their development is an important aspect of a successful fire fighting operation. Likewise, selecting and applying the most effective fire attack strategy and tactics are also important. (Continued) Firefighter I 118

Summary • Failing to do any of these things can result in a fire growing out of control, an increase in fire damage and loss, and possibly in firefighter injuries. (Continued) Firefighter I 119

Summary • Firefighters need to know how to use the fire fighting tools and techniques adopted by their departments. They need to know how to safely and effectively attack and extinguish structure fires, vehicle fires, refuse fires, and wildland fires. Firefighter I 120
