12. Firefighter I 1511 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
13. Firefighter I 1512 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
14. Firefighter I 1513 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
15. Firefighter I 1514 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
16. Firefighter I 1515 Actions to Take Breathing apparatus must be worn during overhaul, extinguishment
Valuables found during overhaul should be turned in to supervisor
17. Firefighter I 1516 Pre-Entry Considerations Conduct quick size-up
Maintain high level of situation awareness
Read fire behavior indicators
Understand crews tactical assignment
18. Firefighter I 1517 Pre-Entry Considerations Identify potential emergency escape routes
Assess forcible entry requirements
Identify hazards
Verify that radios are working, on right channel, being received
19. Firefighter I 1518 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
20. Firefighter I 1519 Gas Cooling Not a fire extinguishment method; way of reducing hazard presented by hot gas layer
Effective when faced with shielded fire
21. Firefighter I 1520 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
22. Firefighter I 1521 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
23. Firefighter I 1522 Direct Attack Most efficient use of water on free-burning fires made by direct attack
24. Firefighter I 1523 Direct Attack Usually from straight or solid stream
Techniques
Water should not be applied long enough to upset thermal layering
25. Firefighter I 1524 Indirect Attack Used when firefighters unable to enter burning building/compartment
Can be made from outside compartment through window or other small opening
26. Firefighter I 1525 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
27. Firefighter I 1526 Combination Attack Uses heat-absorbing technique of cooling hot gas layer followed by heat-reducing direct attack on materials burning near floor level
28. Firefighter I 1527 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
29. Firefighter I 1528 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
30. Firefighter I 1529 Positioning Master Stream Stream should be aimed so it enters structure at upward angle, deflects off ceiling or other overhead objects
31. Firefighter I 1530 Positioning Master Stream Desirable to place master stream device in location that allows stream to cover most surface area of building
32. Firefighter I 1531 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
33. Firefighter I 1532 Supplying Master Streams Always follow SOPs in operation of master streams, handlines
34. Firefighter I 1533 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
35. Firefighter I 1534 Staffing Master Stream Devices Some situations may be too dangerous to have firefighters stationed at master stream device
36. Firefighter I 1535 Elevated Master Stream Devices
37. Firefighter I 1536 Quints Engines equipped with hydraulically operated extension ladder or aerial apparatus equipped with pump
Main ladders range in length
38. Firefighter I 1537 Quints Have waterways pre-plumbed to pumps
Only external support Water supply
Main ladder can be used for rescuing people from exterior windows, ledges, and rooftops within reach of main ladder
39. Firefighter I 1538 Aerial Ladders Apparatus equipped with hydraulically operated extension ladders
40. Firefighter I 1539 Aerial Ladders In North America, usually 50-135 feet (15-41 m), but in Europe sometimes as much as 300 feet (100 m)
Newer aerial ladders equipped with built-in waterways that supply master stream nozzle
41. Firefighter I 1540 Aerial Ladders Master stream nozzles of both types of apparatus can be operated by firefighters at ladder tip/on ground
Can be used for rescuing people from exterior windows, ledges, rooftops within reach
42. Firefighter I 1541 Aerial Platforms Available in two configurations
Aerial ladder platforms
Articulating aerial platforms
43. Firefighter I 1542 Aerial Platforms All equipped with built-in waterways, some with narrow escape ladders
Can be used for rescuing people
44. Firefighter I 1543 Water Towers Engines equipped with hydraulically operated booms that are dedicated to applying water
Most range from 50-130 feet (15-40 m) in length
45. Firefighter I 1544 Water Towers Some have narrow escape ladders attached to boom
Not designed for rescue operations
46. Firefighter I 1545 Class C Fires Involve energized electrical equipment
Major safety hazard Firefighters fail to recognize danger and take appropriate steps for protection
Once electrical power turned off, may self-extinguish or fall into Class A or B
47. Firefighter I 1546 Class C Fires In many commercial and high rise buildings, electrical power necessary to operate essential systems; not to be shut off until ordered
When handling fires in delicate electronic/computer equipment, clean extinguishing agents should be used
48. Firefighter I 1547 Class C Fires Multipurpose dry-chemical agents effective, but some chemically reactive with components
Using water inappropriate because of shock hazard
49. Firefighter I 1548 Class C Fires Fire suppression techniques needed for fires involving transmission lines and equipment, underground lines, commercial high-voltage installations
Departmental operating procedures
50. Firefighter I 1549 Class C Fires: Transmission Lines and Equipment Relatively small number of electrical emergencies involve fires in electrical substations, transmission lines, associated equipment
51. Firefighter I 1550 Class C Fires: Transmission Lines and Equipment Electrical power lines sometimes break, start fires in grass/other vegetation
Fires in electrical transformers common
52. Firefighter I 1551 Class C Fires: Underground Transmission Lines Consist of conduits, vaults below grade
Most serious hazards presented are explosions caused by fuses blowing or short-circuit arcing that ignites accumulated gases
Electrical utility vault
53. Firefighter I 1552 Class C Fires: Commercial High-Voltage Installations Many commercial/industrial complexes have electrical equipment requiring 600+ volts
High-voltage signs may be on doors
Some transformers use flammable coolants that are hazardous
54. Firefighter I 1553 Class C Fires: Commercial High-Voltage Installations Water should not be used because of potential damage to electrical equipment uninvolved in fire
Because of toxic chemicals, smoke is additional hazard
Firefighters should only enter for rescue
55. Firefighter I 1554 Controlling Electrical Power Advantageous for electrical power to remain on for lighting, fire pumps, other essential systems
Decision made by IC and Incident Safety Officer
56. Firefighter I 1555 Controlling Electrical Power When power turned off, should be turned off at main panel by power utility employee
Always follow departmental SOP
57. Firefighter I 1556 Controlling Electrical Power Removing meter may not completely stop flow of electricity because of emergency power capabilities
Considerations for clandestine drug labs, indoor marijuana-growing operations
58. Firefighter I 1557 Electrical Shock Consequences of electrical shock
Factors most affecting seriousness of electrical shock
59. Firefighter I 1558 Guidelines for Electrical Emergencies Establish exclusion zone equal to one span all directions from downed power lines
60. Firefighter I 1559 Guidelines for Electrical Emergencies Be aware other wires may have been weakened by short circuit, may fall at any time
Wear full protective clothing, use only tested and approved tools with insulated handles
61. Firefighter I 1560 Guidelines for Electrical Emergencies Guard against electrical shocks, burns, eye injuries from electrical arcs
Wait for utility workers to cut power lines
62. Firefighter I 1561 Guidelines for Electrical Emergencies Use lockout/tagout devices when working on electrical equipment
Be very careful when raising/lowering ladders near power lines
63. Firefighter I 1562 Guidelines for Electrical Emergencies Do not touch any vehicle/apparatus in contact with electrical wires
Jump clear of apparatus that may be energized by contact with power lines
Do not use solid, straight streams on fires in energized electrical equipment
64. Firefighter I 1563 Guidelines for Electrical Emergencies Use fog streams with at least 100 psi (700 kPa) nozzle pressure
Be aware wire mesh or steel rail fences can be energized by wires outside field of view
65. Firefighter I 1564 Guidelines for Electrical Emergencies Where wires are down, heed any tingling sensation felt in feet, back away
Avoid ground gradient hazards by maintaining large safety zone around downed electrical wires
66. Firefighter I 1565 Company-Level Fire Tactics Standard tactical priorities Life safety, incident stabilization, property conservation
Order of priorities same, but actions taken on fireground may/may not be performed in that order
67. Firefighter I 1566 Responsibilities First Due Engine Company If smoke/fire visible, may be departmental SOP to stop, lay supply line from hydrant or end of driveway into scene
Company officer will conduct rapid initial assessment of situation
68. Firefighter I 1567 Responsibilities First Due Engine Company Assessment determines further actions taken by first-due engine company
If by taking immediate action company can save 1+ lives, will do so even if not enough firefighters on scene to form rapid intervention crew (RIC)
69. Firefighter I 1568 Responsibilities First Due Engine Company If no obvious, immediate life-safety concerns, and fire threatening to extend to another nearby structure, officer may order lines pulled to apply water to exposure
Officer may call for more resources
70. Firefighter I 1569 Responsibilities First Due Engine Company Given a small interior fire, company officer usually assumes Command of incident
Once location of fire known, first-due engine company will position initial attack hoseline to cover priorities
71. Firefighter I 1570 Responsibilities Second Due Engine Company Must make sure adequate water supply established to the fireground,
May finish hose lay, lay additional line, connect to hydrant
Proceeds according to priorities
72. Firefighter I 1571 Responsibilities Fireground Support Company Responsible for performing tasks in order dictated by situation
Functions may be performed by engine personnel when support companies not available
May assist in making fire attack
73. Firefighter I 1572 Responsibilities Rapid Intervention Crew (RIC) Consists of 2+ members wearing appropriate PPE, radio; equipped with special rescue tools, equipment necessary to effect rescue of other emergency personnel
74. Firefighter I 1573 Responsibilities Rapid Intervention Crew (RIC) May be assigned other emergency scene duties; must be prepared to drop those immediately if needed
Exact number determined by IC
75. Firefighter I 1574 Responsibilities Chief Officer/Incident Commander Upon arriving at scene, chief officer may choose to assume Command from original IC, take responsibility for all on-scene operations
76. Firefighter I 1575 Responsibilities Chief Officer/Incident Commander If original IC has incident well organized, progress toward incident stabilization being made, chief officer may assume another role
77. Firefighter I 1576 Fires in Upper Levels of Structures Typical residential response consisting of 2-3 engines; one truck usually inadequate
Large number of firefighters needed
78. Firefighter I 1577 Attacking Fires in Upper Levels Fire attack typically initiated from floor below fire floor
Crews should check floors above main fire floor for fire extension, victims
79. Firefighter I 1578 Attacking Fires in Upper Levels Staging usually established two floors below fire floor
Personnel must exercise caution in streets around outside perimeter of high-rise building
80. Firefighter I 1579 Fires Belowground in Structures Can expose firefighters to extremely hostile conditions
May be possible to control fire without entering basement
81. Firefighter I 1580 Fires Belowground in Structures If cellar nozzle unavailable, firefighters may have to enter burning basement
Good ventilation techniques extremely important
Heavy objects on floor above fire floor can increase chance of floor collapse
82. Firefighter I 1581 Fixed Fire Extinguishing Systems Firefighters should be familiar with systems in buildings protected by their department
Supporting systems critical during fire
83. Firefighter I 1582 Fixed Fire Extinguishing Systems Types of systems
Dangers involved with fires in occupancies with fixed systems
84. Firefighter I 1583 Preincident Plans Often contain SOPs used at these occupancies
Include detailed descriptions of construction features, contents, protection systems, surrounding properties
85. Firefighter I 1584 Preincident Plans May specify procedures for each company
Contain building map
Must be updated regularly
86. Firefighter I 1585 Sprinklered Buildings Support company personnel often used to manage systems operation
Must always follow departmental SOPs regarding actions taken
Some possible actions
87. Firefighter I 1586 Fires in Small Passenger Vehicles Among most common types of fires to which firefighters called
Dictate firefighters wear full PPE, SCBA
88. Firefighter I 1587 Fires in Small Passenger Vehicles Attack line at least 1ฝ-inch (38 mm) hoseline
Booster lines do not provide protection of rapid cooling needed to effectively, safely fight vehicle fire
89. Firefighter I 1588 Fires in Small Passenger Vehicles Attack fire from the side and upwind, uphill when possible
Portable extinguishers can suppress some fires in vehicles engine compartment/electrical system
90. Firefighter I 1589 Basic Procedures One of first actions is to establish safe working zone following U.S. DOT guidelines
Once scene safety established, firefighters can focus on saving vehicle occupants, fighting fire
91. Firefighter I 1590 Basic Procedures Firefighters should stay out of potential travel path of front, rear bumpers
Basic firefighting procedures
92. Firefighter I 1591 Basic Procedures When attacking fire in passenger compartment, use most appropriate nozzle/pattern for situation
Fires in undercarriage
Overhaul
93. Firefighter I 1592 Hazards In addition to hazards associated with other fires, there are hazards specific to vehicle fires
Catalytic converters can act as ignition source to dry grass/other fuels under vehicle
94. Firefighter I 1593 Hazards Interior components on vehicle mainly plastic, which burns rapidly at high temperatures and emits toxic gases
Air bags can deploy from steering wheel, dashboard, door of vehicle
95. Firefighter I 1594 Hazards Hybrid vehicles incorporate high-voltage cables, components
Do not assume any vehicle is without extraordinary hazards
96. Firefighter I 1595 Trash Container Fires Possibility of exposure to toxic products of combustion ever-present
May include hazardous materials or plastics
Full PPE, SCBA should be worn when attacking any trash container fire
97. Firefighter I 1596 Attacking Trash Container Fires Size of attack line depends on size of fire and proximity to exposures
Fires in small piles of trash, garbage cans, small containers can often be extinguished with booster line
98. Firefighter I 1597 Attacking Trash Container Fires Larger piles, larger containers, fires close to exposures should be attacked with at least 1ฝ-inch (38 mm) line
Master streams may be needed to keep trash container fires from spreading
99. Firefighter I 1598 Attacking Trash Container Fires Once fire has been controlled, may be possible to use standard overhaul techniques to complete extinguishment
May be advantageous to attack fire using Class A foam
100. Firefighter I 1599 Confined Spaces Below grade or otherwise without natural/forced ventilation
Atmospheric hazards
Physical hazards
101. Firefighter I 15100 Confined Spaces Where to find information on fire
Hazard mitigation plans
Because of hazards, command post and staging area must be established outside hot zone
102. Firefighter I 15101 Fire Attack Fires may also be attacked indirectly with penetrating nozzles, cellar nozzles, distributor nozzles
Effective air-management system should be part of IAP
103. Firefighter I 15102 Wildland Fires Include those in weeds, grass, field crops, brush, forests, similar vegetation
Have characteristics not comparable to fires in buildings
Main influences on wildland fire behavior
104. Firefighter I 15103 Wildland Fires Fuel Classified by grouping those with similar burning characteristics together
Factors affecting burning characteristics of fuels
105. Firefighter I 15104 Wildland Fires Fuel
106. Firefighter I 15105 Wildland Fires Weather Wind
Temperature
Relative humidity
Precipitation
107. Firefighter I 15106 Wildland Fires Topography Steepness of slope affects both rate, direction of wildland fires spread
Fires will usually spread faster uphill than down; steeper the slope, faster fire spreads
108. Firefighter I 15107 Wildland Fires Topography Aspect
Local terrain features
Drainages
109. Firefighter I 15108 Parts of Wildland Fire
110. Firefighter I 15109 Wildland PPE Firefighters need to wear wildland fire protective clothing because standard structural turnout clothing inappropriate; can be dangerous
111. Firefighter I 15110 Wildland PPE PPE should meet NFPAฎ 1977
NFPAฎ 1500 specifies minimum PPE
Most wildland fire agencies provide additional materials
112. Firefighter I 15111 Attacking Wildland Fires Methods revolve around perimeter control
Control line may be at burning edge, next to it, or a distance away
Objective is to establish control line that completely encircles fire
113. Firefighter I 15112 Wildland Fire Approaches Direct attack is action taken directly against flames at edge or closely parallel
Indirect attack used at varying distances from advancing fire
114. Firefighter I 15113 Wildland Fire Approaches Because wildland fire constantly changing, attack methods may change
115. Firefighter I 15114 Standard Fire Fighting Orders When Fighting Wildland Fires Keep informed on fire weather conditions, forecasts
Know what fire doing at all times
Base all actions on current, expected behavior of fire
116. Firefighter I 15115 Standard Fire Fighting Orders When Fighting Wildland Fires Identify escape routes and safety zones, make them known
Post lookouts when possible danger
Be alert, keep calm, think clearly, act decisively
117. Firefighter I 15116 Standard Fire Fighting Orders When Fighting Wildland Fires Maintain prompt communications with your forces, your supervisor, adjoining forces
Give clear instructions, ensure they are understood
118. Firefighter I 15117 Standard Fire Fighting Orders When Fighting Wildland Fires Maintain control of forces at all times
Fight fire aggressively, providing for safety first
119. Firefighter I 15118 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.
120. Firefighter I 15119 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.
121. Firefighter I 15120 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.
