PG 137
4
Q
Exposures
A
- Position apparatus so that fire streams can be deployed to protect exposures
- Consider fire apparatus as its own exposure –> avoid placing it where it will be subjected to high heat, falling embers, or other products of combustion
PG 137
5
Q
Water Supply
A
- Consider the need to establish own water supply or lay in
- Consider supply hose placement in attempt to NOT block later arriving units
6
Q
Method of Attack
A
- Handlines or portable master streams = pumper must be positioned in close proximity to building
- Fixed appliance = apparatus must be positioned where it is close enough to building, but not in danger if collapse of structure should occur
PG 137
7
Q
Hoseline Deployment
A
- Position apparatus to support deployment of hoselines for fire attach or supply lines to FDC’s
PG 137
8
Q

9
Q
Terrain
A

10
Q

PG 139
14
Q
Positioning to Support Aerial Apparatus
A
- First arriving apparatus must position to best support their functions, while also considering positioning/functions of later arriving aerial apparatus
- “Inside/outside method”
- Must consider the spread of the stabilizing system of the aerial apparatus
- If supporting/pumping aerial, pumper apparatus must be parked as feasibly close to aerial as possible to minimize friction loss
PG 140-141
15
Q
“Inside/Outside” Method of Apparatus Placement
A
- INSIDE: If building is LESS THAN 5 floors tall = attack pumper is positioned on the side of the street closest to (INSIDE the aerial) the building
- OUTSIDE: If building is MORE THAN 5 floors tall = attack pumper is positioned on side of street away from (OUTSIDE the aerial) the building
PG 140
16
Q

- When supporting FDC, position as closely to water supply as possible
PG 141
17
Q
Fire Department Connection (FDC)

Point at which the fire department can connect into a sprinkler or standpipe system to boost the water pressure and flow in the system
- This connection consists of a clappered siamese with two or more 2.5” intakes or one large diameter intake
PG 141
18
Q
Drafting Operations
A
- Required when a pumper must be supplied from a static water supply such as storage tank, lake, stream, pool, etc.
- More common in rural areas where there is a lack of hydrants
PG 141
19
Q
Drafting
A
- Process of acquiring water from a static source and transferring it into a pump that is above the source’s level
- Atmospheric pressure on the water surface forces the water into the pump where a partial vacuum was created
PG 141
20
Q
Static Water Supply
A
Supply of water at rest that does not provide a pressure head for fire suppression, but may be employed as a suction source for fire pumps (reservoir, pond, lake, pool)
PG 141
21
Q
Dry Hydrant
A
- Permanently installed pipe that has pumper suction connections installed at static water sources to speed drafting operations
- Consists of intake hose connection on the shore and length of pipe extended into the water with a strainer on the end
PG 142
22
Q
Side Intake Connections
A
Position apparatus close to the curb with pump panel a few feet short of being in line with the hydrant (stopping short will allow supply line to curve and prevent kinking)
PG 143
23
Q
Dual Pumping
A
- Operation where a strong hydrant is used to supply two pumpers by connecting the pumpers intake-to-intake
- The second pumper receives the excess water not being pumped by the first pumper, which is directly connected to the water supply source
PG 144
24
Q
Tandem Pumping
A
- Short relay operation in which the pumper taking water from the supply source pumps into the intake of the second pumper
- The second pumper then boosts the pressure of the water even higher
- This method is used when pressures higher than the capability of a single pump are required
Tandem pumping apparatus can be positioned up to 300 feet apart
PG 144
25
NFPA 1962Q
Standard for the Inspection, Care, and Use of Fire Hose, Couplings, Nozzles, and the Service Testing of Fire Hose
PG 146
26
Wildland Structure Protection
Apparatus should be backed in, but once the apparatus arrives at the structure it is assigned to protect:
- Position apparatus off roadway to avoid blocking traffic
- Clear away nearby brush
- Position on leeward side of structure to minimize exposures/heat/embers
- Position nearby, but safe distance from structure
- Keep doors and windows closed
- Place vehicle's air conditioning on recirculation mode to avoid drawing in smoke
PG 147
27
Wildland Fire Attack
- Generally operate from several different positions during course of operations --> must constantly be aware of changing conditions to reposition apparatus for most optimal use and safety
PG 147
28
Anchor Point
- Point from which a fire line is begun
- Usually a natural or man-made barrier that prevents fire spread and the possibility of the crew being flanked while constructing the fire line
- Ex: lakes, ponds, streams, roads, earlier burns, rockslides, cliffs
PG 147
29
Fording
- Ability of an apparatus to traverse a body of standing water
- Apparatus specifications should list the specific water depths through which trucks must be able to drive
PG 148
30
Mop Up
1. Overhaul of a fire or hazardous material scene
2. In wildland fire fighting, the act of making a fire safe after it is controlled by extinguishing or removing burning material along or near the control line, felling dead trees (snags), and trenching logs to prevent rolling
PG 148
31
Staging
- Standardized process or procedure by which available resources responding to a fire or other emergency incident are held in reserve at a location away from an incident while awaiting assignment
- Level 1
- Level 2
- Base
PG 150
32
Level 1 Staging
- Used on all multi-company emergency responses
- First arriving vehicles of each type proceed directly to scene and the others stand by a block or two from the scene and await orders
- Units usually stage at the last intersection on their route of travel before reaching the reported incident location
- Engine companies typically stage near hydrant or water source
PG 150
33
Level 2 Staging
- Used on large-scale incidents where a larger number of fire and emergency services companies are responding
- These companies are sent to a specified remote location to await assignment
- Company officer of first unit to arrive in staging becomes Staging Area Manager
PG 150
34
Base
- Location at which the primary Incident Management Logistics functions are coordinated and administered
- The IC Post may be co-located with the Base
- There is only one Base per incident
PG 150
35
HAZMAT Incidents
- Obtain information regarding wind speed and direction from dispatch or by direct observation
- Approach upwind and uphill
- Do not drive apparatus directly to the scene until the material involved has been identified
- Position apparatus and personnel well short of the scene
PG 153
36
Hazard Control Zones
- System of barriers surrounding designated areas at emergency scenes
- Intended to limit the number of persons exposed to a hazard and to facilitate its mitigation
- Three zones: HOT zone (restricted), WARM zone (limited access), COLD zone (support)
PG 153
37
Hot Zone
- Potentially hazardous area immediately surrounding the incident site
- Requires appropriate protection clothing and other safety precautions for entry
- RESTRICTED, EXCLUSION, RED ZONE
PG 154
38
Warm Zone
- Area between the hot zone and cold zone that usually contains the decontamination corridor
- Typically requires a lesser degree of personal protective equipment than the hot zone
