85
The age of the hose is determined by the serial number stamped on the coupling. What two numbers are used as a reference?
First two (i.e. 970023- the numbers 97 would be a 1997 length needing replacement in 2007). Any hose that will reach 10 years in current calendar year is to be taken out of service.

Public hallway/stairway, Compactor room, & shafts
89
When the exact location of the fire has been determined it must be conveyed to the other units operating on the scene. What must be relayed to members stretching the initial hoseline?
The most direct route to fire area
90
In some situations, what may be done to play a vital role in confining the fire while hoselines are being stretched to the location of the fire?
Closing of a door or window
91
What is the difference between Initial extinguishment and Final extinguishment?
Initial includes "knock down" of visible flames & readily apparent burning & smoldering material debris.
Final means any fire uncovered by "opening up" & overhauling procedures has been extinguished
92
The progression of modern content fire development curve:
Incipient,
Rapid Growth stage consuming O2 very quickly,
Early O2 limited Decay stage (remains if NO add'l O2 added): if add'l O2 added to fire area a 2nd rapid Growth stage may be encountered,
2nd decay stage as fuel load depleted or fire extinguished
93
During the Growth stage Rollover may occur.
| This is an indicator that fire conditions are rapidly changing. What must members do if they observe rollover?
If rollover observed and members are NOT operating under the protection of a charged HL, they shall immediately leave & isolate the fire area
94
Modern content fires: as fire goes into an early decay stage prior to reaching full development, what can happen when additional oxygen is added?
A Ventilation Induced Flashover resulting in rapid fire development
95
After Eng Off determines that a HL is needed, what info should be relayed to members performing the stretch?
Location, Route, & Number of lengths req'd.
96
If NO Ladder company is present, can the Eng Off attempt to enter the IDLH?
He may enter when teamed up with another available member. He may only enter individually to address a known life hazard
97
What shall the Eng Off do if he finds the entrance door to the fire area and entry is not possible?
The door should be closed immediately to control the flowpath, preventing products of combustion from entering the hallway and contaminating the upper flrs & preventing the escape or removal of civilians from above the fire. Door control is CRITICAL
98
Prior to opening the door to the fire area for advancement of the line, the Eng Off MUST ensure _
That NO FF's will be exposed in the hallway or on the stairs above as the fire attack is initiated. This can be done via HT or in person.
99
Can the nozzle be opened on smoke?
As a general rule, noz should NOT be opened on smoke. If fire or high heat is encountered the nozzle can be used to cool & push the fire gases back toward the fire area by directing it upward toward the ceiling using a rapid side to side or clockwise motion
100
When is it appropriate to place a yellow disk on a Siamese of auxiliary fire protection system?

C) Only an IC at the rank of Deputy Chief or higher may order the use of the 3rd stage
D) Increased efficiency of a 3rd stage Eng makes it preferred choice for pumping ops requiring discharge pressures less than 500 psi
