- All organizations must have regulations,
policies, and procedures. - Regulations are rules that determine how an
organization operates. - Policies are formal statements or directives.
- Standards are consensus documents
- Volunteer departments may be organized as
independent corporations.
3FD Organization, Command and Control

low/medium-pressure. - High-pressure bags operate at a maximum inflation
pressure of about 130 psi. - Bags come in sizes ranging from 6x 6 to 36x
36. - Low/medium-pressure bags can lift very heavy
loads.

- This is one of the most dangerous rescue
situations. - Training, practicing, and planning are the best
ways to reduce danger. - Always enter in teams of two or more.
- Two firefighters in full gear and a charged line
should be ready to go in, if needed. - Known as two-in/two-out rule (OSHA)
15Search of Burning Structures (2 of 3)
- Perform a quick survey of structure and
surroundings. - Always carry a tool, flashlight, and radio when
searching. - Thermal imagers may help see through smoke.
- Search single-family structures using wall as
reference. - Known as right-handed or left-handed search
16Search of Burning Structures (3 of 3)
- Commercial or industrial structures require use
of lifeline or guideline. - There are two operations to searching a building.
- Primary search
- Window search
- Vent Enter Search
- Secondary search
17Victim Removal, Drags, and Carries
- Victims must be removed carefully and
expeditiously. - Try to not cause further injury or aggravate
existing injury. - You may not be able to give care due to hazardous
or hostile environment. - Use tight core to create power and reduce
injury.
18Blanket Drag
19Techniques for Breaching Walls
- Breaching walls

during large incidents. - Some SOPs call for time marking incidents at
regular intervals. - Initial Status within 10 minutes of arrival
- Status Reports every 10 15 minutes
- PAR 10 30 minutes, after emergencies, or mode
changes
24Endothermic Reaction
- When molecules are joined, heat is absorbed.
- This is known as endothermic reaction.
25Exothermic Reaction
- When bonds break, heat is released.
- This is known as an exothermic reaction.
26Vapor Pressure and Vapor Density
- Air pressure changes at different altitudes.
- At sea level, air pressure is 14.7 psi.
- Gases that weigh less than the same volume of air
will be lighter and tend to rise. - Gases that weigh greater than air will be heavier
and tend to drop to low lying areas.
27Nozzles
- Fog Nozzles
- Operate from 50 to 100 psi
- Provide good reach that varies with pattern
- Provide good penetration
- Produce more steam
- Can be used to assist in horizontal ventilation
28Nozzles
- Solid Stream
- Hand line tips are from 3/4 to 1¼ at 50 psi.
- Master stream tips are 1 and larger at 80 psi.
- Hand lines can reach over 70 and master streams
about 100. - Have less effect on a rooms thermal balance.
- Have good penetration.
29Nozzles
- Special Purpose Nozzles
- These were developed for use in limited types of
situations. - Cellar nozzles and Bresnan distributors are
effective for basement and cellar fires. - Piercing nozzles were designed to penetrate
aircraft skin and building walls and floors. - Water curtain nozzle is designed to spray water
to protect against exposures to heat.
30Foam Characteristics
- Foams ability to extinguish fires is based on
several characteristics. - Application rate
- Heat resistance
- Knockdown speed
- Fuel resistance
- Vapor suppression
31Classification of Fuels
- Class A material can be extinguished using a
detergent-based foam. - Class B fires include flammable liquids and large
quantities of foam are best for these types of
fires. - Hydrocarbons
32Application of Foam
- Foam is a mixture that requires a device to
combine the foam concentrate with water. - Air must then be added.
- An eductor is often used which works on the
venturi principle. - Foam can also be delivered by a compressed air
foam system. - Foam nozzles have the ability to aspirate proper
quantities of air into the solution and apply the
foam to the fuel. - Must have proper pressure and flow
33Service Testing of Fire Hose (1 of 2)
- Test fire hose prior to placing in use, and then
retest annually. - Use a record keeping system.
- Begin testing with a visual inspection.
- Check for thread damage.
- Check couplings
- Service testing involves testing hose under
pressure.
34Service Testing of Fire Hose (2 of 2)
- Pressure testing is designed to check for hose
failure. - Place a hose test valve on the discharge pump to
limit flow rate of the water. - Attach hoselines to the pumping device and test
pressure. - Do not test more than 300 feet of hose at a time.
- Follow local SOPs for testing.
35Protective Systems

- Building codes
- Fire Alarms
- Protection of Structures
- Sprinklers
- Standpipes

hose - Class III- Both users, 500 GPM, 2½ 1½
36Preaction Systems
37Water Distribution Systems
- After treatment, water goes into the distribution
system. - Water mains are divided into feeders.
- Primary feeders divide into secondary feeders and
distribution lines. - Good systems are interconnected into loops and
grids.
38Process of Fire Extinguishment
- First, create a plan of attack.
- Apply plan of action quickly, efficiently,and as
safely as possible. - Attack methods
- Direct
- Indirect
- Combination
- The goal with any method is to save property.
39Flammable Gas Fire
Vapor
Liquid
40Fire Cause and Determination
- Be aware of possible causes.
- Be observant.
- Do not remove anything until approved by
investigator. - Any small markings or findings are valuable to
the investigation.
41Fire Cause and Determination
- Preservation of evidence
- Point of origin determination
- V patterns
- Depth of Char
42Inspection Responsibilities
- Equipment
- Preparation for inspections
- Conducting the inspection
- Concluding the inspection
- Reinspection
43Pre-incident Management Process
- Pre-incident management and preplanning are
related, yet different. - Deciding to preplan
- Site visit
- Diagrams
- Seeking input from others
- The finished document
44Type I Fire Resistive Construction
- It is designed to stop spread of fire from one
area to another. - Steel and concrete used for structural members.
- There is a three- to four-hour fire resistive
requirement. - Fire may spread through broken windows, elevator
shafts, and utility runs. - Spalling weakens structure
45Type II Noncombustible Construction
- Steel is the primary material used.
- It may have combustible contents causing fire
spread. - Suburban strip malls are typically Type II
construction.
46Type III Ordinary Construction
- Masonry walls with wood roofs and floors
- May have many void spaces for fire spread
- Sagging floors of older buildings reinforced with
steel rods - Floor beams, typically gravity fit, may fail
quickly when floors sag
47Type IV Heavy Timber Construction
- Thick masonry walls with large dimension lumber
for floors and roofs. - Few void spaces, but many open spaces.
- Floors will collapse when sagging leaving walls
unsupported.
48Type V Frame Construction
- The wood frame is most common.
- It may be balloon frame or platform.
- Newer lightweight buildings are like a
horizontal balloon frame. (serious hazard) - It is protected from fire by covering with gypsum
board. - Brick veneers may be frame construction.
49Construction Type to Occupancy Use
- Anticipated use determines occupancy
classification. - Common classifications
- Residential
- Commercial
- Business
- Industrial
- Hazardous
- Educational
- Classification will help firefighters understand
specific fire problems. - Buildings constructed under one type may have
been converted to different use.
50Building Materials
- Effects of heat/fire
- Steel expands and weakens
- Wood chars, dimensions effect strength
- Concrete spalls, pieces break off
51Collapse Hazards at Structure FiresTrusses
- Trusses are beams that use triangles of lumber to
replace mass. - Failure of a single part will cause entire truss
to fail. - Failure of a single truss may lead to multiple
truss failures. - Gusset plates used to join wood components absorb
heat faster than the wood.
52Collapse Hazards at Structure FiresTrusses
- Steel trusses have a high surface to mass ratio.
- Truss roof collapses have killed and injured many
firefighters. - An open web steel truss is called a bar joist.
53Collapse Hazards at Structure FiresSigns
- Waiting for visual indicators is dangerous rely
on construction knowledge and preplanning.
54Collapse Hazards at Structure FiresSigns
- Factors and visual indicators that may assist in
predicting a collapse - Age of building
- Cracks
- Presence of tie rods
- Open spans
- Sagging floors
- Smoke from cracks
- Bulging walls
55Hazardous Material Management Systems
- Different management systems are available to
manage HAZMAT incidents - 8-Step Process
- GEDAPER process
- DECIDE process
- HAZWOPER regulations require the use of Incident
Management System (IMS).
