Mission Statement
The mission of the Escondido Fire Department is to serve the public and to safeguard the community from the impact of fire, medical, and environmental emergencies through education, emergency services, and enforcement.
Code 3 Driving Definition
The immediate response to a call for emergency assistance utilizing warning lights and sirens.
Priority Traffic
Any unit encountering an emergency situation not perilous to personnel, and will receive high priority from the Communications Center and other units.
Example: coming across a traffic accident.
Emergency Traffic
Any unit (or individual) encountering an immediately perilous situation.
- talkgroup belongs to unit declaring emergency traffic.
- dispatch broadcasts 3-beep alert across all talkgroups (patches talkgroups) assigned to the incident.
- IC announces “Emergency Traffic” three times
- PAR then Ic clears Emergency Traffic
Evacuation Order
Emergency Traffic declared and after emergency Traffic announced three times, engineer will sounds the evacuation signal:
*quick repeated air horn blasts for 10 seconds followed by 10 seconds of silence. Repeat three times totaling 50 seconds.
Mayday Declaration
Emergency condition where a firefighter may be lost, trapped, missing, injured, or disoriented to a level where assistance is needed.
*if using radio report who, what, where, air before PASS activation.
*activate EMERGENCY button if not acknowledged
which will move FF’s channel to PAPPA.
*IC can move tactical channel if downed FF doesn’t use EMERGENCY button.
Emergency Button Activation
When activated, indicated radio I.D. And alias user ID that transmitted emergency.
- IC will be notified of activation by dispatch; IC should request emergency “warble” tones then implement Mayday procedure.
- non-fire incidents will result in dispatch asking “update our status”. Any other response other than “accidental activation” will result in code 3 response from PD.

Characteristics of Tactical Effectiveness of Hose Lines

- Placement
- Speed
- Mobility
- Supply
2 categories IC must regard apparatus’ status
- Assigned
- Available (staging)
Primary Staging (First Alarm)
Resources will stage, uncommitted, approximately one block from the incident until assigned by IC. Consider access, direction of travel, and water supply.
Secondary Staging
Resources from 2nd alarm or greater. Ideally a Staging Area Manager is assigned. Located in area not impacting operations and large enough to accommodate apparatus needed.
On Deck
Forward Staging position located just outside the immediate hazard zone. When assigned, a location must be given.
On-Deck crew assignments
- IRIC
- Reinforce tactical position
- Relieve another crew
- Assigned to division/group
- Any other tactical position assigned by IC
Company Recycling
A timely and efficient means or air replacement and rehydration of companies while maintaining their assignment. Up to 2-3 cylinders.
Class A Foam
- How it works - How it’s applied - How king it lasts
- consists of hydrocarbon surfactant molecules reducing surface tension of the water allowed better absorption of water into fuels. Becomes carbon-loving and emulsifying solution allowing better absorption and wetting.
- standard combination nozzle and low-expansion foam nozzle (used to pre-treat structures for Wildland firefighting.
- 1 hour hot weather, 4 hours cool weather
Foam Percentages (Wildland)
Duff/mop up 0.1-0.2%
Grass/Light Brush 0.3-0.4%
Brush 0.5-0.6%
Indirect Attack 0.6-1.0%
Foam Pumps We Have
HALE FoamPro 2001 E134,
PIERCE Huskey 12 (E135, KME)
HALE FoamMaster
-Automatic proportioning, direct injected
How Foam Pump Works
- Flow meter measure water flow and sends info to control module.
- Flow meter is compared to foam pump output to maintain desired percentage regardless of pump intake or discharge pressures.
- Foam is injected directly into stream on DISCHARGE side.
4 elements of good foam production
Foam Concentrate
Water
Air
Mechanical Agitation
In-Line Foam Eductors
- eductor and nozzle hydraulically matched
- foam concentrate matches setting on eductor
- use properly sized supply line for eductor avoiding kinks
- avoid elbows when connecting eductor and never gate down
- Intake for eductor is 150 psi. Nozzle and eductor GPM must match.
- Angus FD450H Eductor rated flow 120 GPM at 100psi
Foam Application Rate
Determines GPM flow needed to extinguish certain size flammable liquid spill
.10 GPM x fire per square foot (FSF)
.10 GPM = gallons per minute of foam solution needed per 1 square foot of fire
Ex: 1200 square foot spill on fire
.10 x 1200 = 120 GPM to extinguish fire
Determining total amount of foam concentrate needed (FCN)
Foam percentage x eductor GPM (number from FAR) x time (min of 10 minutes)
- example: 3% foam concentrate x 120 GPM= 3.6 gallons of foam concentrate needed
3. 6 gallons x 10 minutes = 36 total gallons
***maximum size for one eductor is 1200 sq. Ft.
***one 5-gallon jug at 3% covers about 1200 sq ft. One time
Estimating Spill Size for Foam Application
1 Gallon = 32 square feet (4x8’)
5 Gallon = 144 square feet (12’x12’)
55 Gallon = 1200 sq. Feet
-Clean gutter takes 30 feet per gallon
Dirt/Unclean surface
- 1 square foot = 1 gallon - 5 square feet = 25 square feet - 55 gallon 490 square feet
IC/Division Sup/Company officer responsibilities for accountability
IC - Strategic level; task level too is no division assigned
Division/Group Sup - Tactical level
Company Officer - Task level. Maintain accountability through voice, touch, sight, or radio.

4 stages of 4-strike engine
Intake: Fills cylinder with air when valves open
Compression: compressed air and atomized diesel that injected
Power: compressed air/diesel mixture explodes driving cylinder making power
Exhaust: removes burned mixture from cylinder when exhaust valves open
3 characteristics of Escondido engines
In-line 6 cylinder
Turbo charged
After cooled
Equation to determine engine displacement
.7854 x bore squared x stroke x number of cylinders
Compression Ratio
Ratio of air when cylinder at BDC to TDC. Example: 17:1 means air is compressed to 1/17th of volume when at TDC
Equation to determine horsepower
Revolutions per minute (RPM) x Torque/5252
Components of a cooling system
Cylinder block Head water jacket Thermostat Water pump Radiator Radiator cap Fan Fan drive belt Hoses
How a turbocharger works
Exhaust exiting the exhaust manifold spins a turbine that is connected by a rod to compressor turbine wheel. The compressor wheel spins, drawing in and compressing air. Air is then drawn through an inter cooler to cool the air (more available O2) before entering the intake manifold.
5 main things needed by fuel injection system
- Meter correct quantity of fuel injected
- Time start and finish if fuel injection correctly
- Control rate of fuel injection
- Atomized fuel into very fine droplets
- Properly distribute fuel within combustion chamber.
Two methods to keep diesel moisture-free
Don’t let it sit longer than 2 months
Keep dowel fuel tanks as full as possible
