Engine Company Operations Manual Flashcards
This manual excludes engine company operations at
wildland and high-rise fires
The primary function of an Engine Company is to
supply water and operate fire streams
to protect lives and property
What is the most effective means of providing safety for our members and the civilians we protect.
Rapid and aggressive fire control
Hose lines are placed
strategically, with the general practice of placing streams between ______ during offensive fire attack and between ________ in defensive
operations
the fire and potential
victims
the fire and exposures
What needs to happen before backup lines are placed in service
The
first attack line should be stretched, charged, and operating
Backup hoses should be larger than the initial attack lines and should be used
whenever the initial attack lines cannot extinguish the fire.
When determining fire flow, the
, the traditional formula of L x W /3 no longer applies to today’s
modern fire environments.
What measurement gives an accurate fire flow?
LxW of the building
What factors will increase the required fire flow?
fuel load, wind, and flow
path
All 1¾” handlines used for interior fire attack shall be operated to deliver a
minimum of _______ gallons per minute.
150
All 2½” handlines used for interior fire attack shall be operated to deliver a
minimum of _____ gallons per minute.
250
Generally, 2½” attack lines should be used for:
Fires considered to be advanced in nature (larger than 450 square feet)
Defensive operations
Obvious working fires in large buildings where the fire’s location is not readily apparent
Fires in large un-compartmented assembly or commercial structures
Standpipe operations
Any fire requiring a flow greater than 1¾” can deliver
How to reduce fire spread from flow path?
cooling fire gases while quickly moving to and extinguishing the seat of the fire
Controlling
the flow path improves
victim survivability, firefighter safety, reduces fire growth and
temperatures within the structure
Who must account for door control?
2nd unit on scene regardless of type
The Door Control person shall
keep their
unit designator so Command can keep their accountability since Door Control is performed in the Hot Zone. At the completion of Door Control, the member performing
the task should return to their crew if safe to do so or exit the Hot Zone and standby.
How to estimate the amount of hose needed inside a building?
Generally,
adding the width and depth of a building yields the required length of hose needed inside
Attack positions should never be further than ____ feet from a safe refuge.
150
What is needed at large and
mega-sized commercial occupancies?
commercial occupancies, effective recon prior to stretching the line is needed
to select an entrance that puts the attack team within this distance.
In occupancies with multiple floors, an additional _____ feet of hose is required to traverse
one floor
50
when a stairwell with a well
hole is used or if the hose is stretched via rope from the outside of the building, how much extra hose is needed
10 feet per floor
When should engines should consider the use of a “Horizontal Standpipe”
fires where setbacks,
parking, building arrangement, or other problems preclude the Engine from positioning
close to the fire
A transitional attack is often referred to as?
“Hit it hard from the yard” or “Softening the target.
Proper technique of a transitional attack includes:
Using a solid or straight stream pattern at a steep angle into the window
The stream enters the window close to the sill aimed at the ceiling
Do not excessively move the nozzle; allow steam to escape from the window
Apply water for 10 – 30 seconds
A transitional attack should NOT be used if:
It delays the interior attack
There is an obvious rescue within the flow path
You cannot get water on the fire
You need to create an opening
(e.g., break a window) to get water on the fire
(Except in the case of a basement fire, as outlined below)
What are the two significant risks of basement fires?
collapse and flow path
Tests have shown
consistent failure of the floor above the basement regardless of construction type within
_______minutes of direct fire impingement
8
How to mitigate the dangers of a basement fire?
a 360-degree assessment of the structure should be completed prior to committing crews to fire attack to identify the location of the fire and if the structure has a
basement. If a structure is found to have a basement, the terms used to describe it are
either a “walkout or no walkout.”
Walkout basement fires should be attacked from?
the basement access point. If possible,
a transitional attack should be started through this access point, from the exterior
In walk-out basement fires, all operations on the floor above the basement should be
coordinated
with fire attack
Non-walk-out basement fires should be fought by
transitional attack from a window closest to the fire should be made into the basement
prior to advancing the attack line from the floor above. The first line established should
apply water to the basement fire after creating an opening
What is extremely critical for non-walk-out basement operations
Door control is extremely
critical during this operation
What should be considered if there is difficulty controlling the fire during a transitional fire attack on basements is
Defensive operations
Master streams should be considered at any fire requiring a fire flow of greater than ______
gpm and should operate at a minimum flow of _____ gpm when possible.
250, 500
All Engine mounted and
portable master stream appliances shall have
smooth bore stack tips in place
The best way to secure a portable master stream is to provide a straight run of 2 ½” hose at least
_____ from each hose connection
20’
Most portable master stream manufacturers also recommend
securing the portable master stream from the front using
using rope, chain, or webbing.
Whenever possible, a portable master stream should be secured to a
rigid stationary
object in this manner
Which way is no longer recommended to secure a master stream device?
Rams horn
