1) Please choose the correct lightweight construction description(s) from the list below?
(Section 1.4, 1.5, & 1.6)
A) The strength of a lightweight system is obtained through the interconnection of multiple
structural components providing support in compression only.
B) The decrease in size and mass of the individual structural components will impact the
stability of all other structural components; if one fails, the others may fail as well.
C) In any building construction, the critical area subject to failure as a result of fire is the point
of connection.
D) All of the above.
- B, C
1.4 In the absence of increased mass, the strength of a lightweight system is obtained through
the interconnection of multiple structural components providing support in compression
and tension. Furthermore, the decrease in size and mass of the individual structural
components will impact the stability of all other structural components; if one fails, the
others may fail as well.
1.5 In any building construction, the critical area subject to failure as a result of fire is the
point of connection.
2) In private dwellings constructed with lightweight materials, when fire extends from the
building’s contents to its structural components, collapse may occur within __________. Please
fill in the blank? (Section 1.7)
A) 20 minutes
B) 1 hour
C) 5 to 10 minutes
D) 15 minutes
- C
2) In private dwellings constructed with lightweight materials, when fire extends from the
building’s contents to its structural components, collapse may occur within 5 to 10 minutes.
Collapse in lightweight structures can occur suddenly, and with little or no warning signs.
Collapse is always the primary consideration in buildings constructed with lightweight materials.
3) Please choose an incorrect item about fires in “traditional” private dwellings built of
ordinary/wood frame construction from the list below? (Section 1.6)
A) Early collapse is always a primary consideration.
B) Depending on the duration and intensity of fire, the size of the structural components, and
the type of construction involved, the amount of time before collapse occurs is generally
estimated to be an hour.
C) When there is no ceiling to provide protection, therefore exposing structural components,
failure can occur within 20 minutes.
- A
4) The most important factor to a safe and successful operation at a fire in a building
constructed of lightweight construction is the identification of the presence of lightweight
materials. Areas unsupported by columns with spans greater than ______ are generally an
indication that lightweight construction is present. Please fill in the blank? (Section 1.8)
A) 15 feet
B) 20 feet
C) 25 feet
D) None of the above
- C
4) Older Cast-Iron Lofts, 1840s – 1870s: Maximum 7 to 8 stories in height having front and
rear exterior walls of brick, stone or iron. Side exterior walls are of brick construction. Frontage
is usually 25 feet (indicating no interior columns) with depths reaching 90 feet and frontage on
only one street

structure (i.e. renovated private dwellings).
6) The most common type of peaked roof found in private dwellings using lightweight
construction is the _______________________. Please fill in the blank? (Section 2.2.5)
A) open-web lightweight wood truss
B) closed-web lightweight wood truss
C) wood I-beams
D) metal c-joist
- A
6) When a lightweight wood truss peaked roof is exposed to sufficient fire, the rafters (top
chord of the truss), the roof decking, and ceiling joists (bottom chord of the truss) can be
expected to collapse as one complete unit into the structure, exposing firefighters to falling and
burning debris.
7) Please choose an incorrect item in regards to Lightweight Parallel Chord Wood Truss?
(Section 3.2)
A) When lightweight wood trusses are exposed to fire, high heat, or prolonged exposure to
water, the gang nails may loosen and fail, causing the entire span of that particular truss section
to fail.
B) The surface-to-mass ratio of the wood trusses provides an abundant fuel source, and the air
supply in the concealed truss void allows for rapid horizontal extension.
C) Due to the open-web characteristic of the truss system, fire which has entered a ceiling
(trussloft) or roof space (cockloft/attic) may likely affect all truss supports on that level, creating
the potential for a large-scale collapse of the area supported by the affected trusses.
D) This type of support system is made up of 2x3” or 2x4” wooden web and chord members,
these members are the weakest point of the support system.
8)
- D
3.2 Lightweight Parallel Chord Wood Truss
This type of support system is made up of 2x3” or 2x4” wooden web and chord members
connected with sheet metal gusset plates (also referred to as gang nails). Since these
connections only penetrate 1/4” - 1/2” into the wooden truss member, the gang nails are
the weakest point of the support system. When exposed to fire and/or high heat, failure at
the point of connection should be expected before failure of the structural wood components.
8) Please choose a correct item in regards to Laminated Wood I-Beams? (Section 3.3)
A) This type of support system is primarily comprised of 1/2” oriented strand board (OSB) or
3/8”- 1/2” plywood web members, and 2x3” or 2x4” wood flanges.
B) The web is fitted and nailed into a routed slot in the top and bottom flanges.
C) In some cases, they may span lengths of over 45 feet, never more than 60 feet.
D) The strength of the beam is a function of the depth of the flange and the mass of the web.
These beams are usually connected to load bearing walls with sheet metal joist hangers.
- A
3.3 Laminated Wood I-Beams
3.3.1 This type of support system is primarily comprised of 1/2” oriented strand board
(OSB) or 3/8”- 1/2” plywood web members, and 2x3” or 2x4” wood flanges. The
web is fitted and glued into a routed slot in the top and bottom flanges. In some
cases, they may span lengths of over 60 feet. The strength of the beam is a
function of the mass of the flange and the depth of the web. These beams are
usually connected to load bearing walls with sheet metal joist hangers.
9) Please choose an incorrect item in regards to Metal C-Joists? (Section 3.4)
A) This type of support system uses lightweight cold-formed steel joists to support the floors
and/or roof.
B) In order to stabilize the building, the joists must be braced with strapping and/or blocking
to prevent them from twisting.
C) Metal C-Joists may come with pre-drilled holes for plumbing and electrical lines.
D) A newer type of C-Joist, with design characteristics similar to laminated wood I-beams, has
larger openings that allows for the easier running of utilities, and the potential for fire and heat
spread is significantly greater.
E) When exposed to fire and/or high heat, these lightweight steel joists will lose strength and
fail rapidly.
- D
3.4.2 Metal C-Joists may come with pre-drilled holes for plumbing and electrical lines.
(Figure 8) A newer type of C-Joist, with design characteristics similar to
lightweight parallel chord wood truss, has larger openings that allows for the
easier running of utilities, and the potential for fire and heat spread is significantly
greater. (Figure 9) When exposed to fire and/or high heat, these lightweight steel
joists will lose strength and fail rapidly.
9) I-beams are pre-engineered, and may come with openings in the web to accommodate
utilities. In other instances, builders will bore holes in the web for plumbing, electrical lines, and
HVAC ductwork, thus compromising its strength.
10) A heavy fire and smoke condition on a floor or in the cellar of a private dwelling
accompanied by little or no smoke on the floor or floors above may be an indication of a
concrete or gypsum floor poured over corrugated steel (Q-decking) supported by _______.
Please fill in the blank? (Section 3.4.3)
A) Lightweight parallel chord truss
B) Laminated wood I-beams
C) Metal C-joists
D) Composite truss
- C
3.4.3 A heavy fire and smoke condition on a floor or in the cellar accompanied by little
or no smoke condition on the floor or floors above may be an indication of a
concrete or gypsum floor poured over corrugated steel (Q-decking) supported by
C-Joists. The additional dead load may lead to early floor collapse; caution
should be used at fires in buildings with this type of construction.
11) “Under fire conditions, the “Space Joist” will not react the same as other lightweight
(wood or metal) trusses.” Please indicate if you agree or disagree with above statement in
quotes? (Section 3.5)
A) Agree or D) Disagree
- A
3.5 Composite Truss
This type of truss system is similar in design to a lightweight parallel chord wood truss,
but comprised of two types of materials: wood and steel. A formed sheet metal web is
attached to 2x3” or 2x4” wood chords with nails or sheet metal gang nails. It is
commercially known as a “Space Joist”.
3.5.1 Under fire conditions, the composite truss will react the same as other lightweight
(wood or metal) trusses, they will lose strength and fail rapidly (Figure 10)
12) You are operating at a fire in a private dwelling where lightweight construction is
suspected, you would know that the examination of what voids shall be conducted as soon as
conditions permit? (Section 4.1.2)
A) Wall
B) Floor
C) Ceiling
D) All of the above
- C
13) Once the fire enters the concealed space containing lightweight trusses or joists, it can
rapidly travel to remote locations. The Incident Commander (IC) shall immediately be notified.
All members shall be directed not to enter the fire area or areas directly above the fire until the
IC determines the risk of a planned coordinated interior attack. The above statements are
especially true with which of the following construction material(s) listed below?
(Section 4.1.4)
A) Open-web lightweight parallel chord wood trusses
B) Composite trusses
C) Laminated wood I-beams

constructed of lightweight materials. Please choose an incorrect statement that you made during
the drill? (Section 4.1.5 to 4.1.8)
A) A Thermal Imaging Camera (TIC) should be used to assist in detecting fire and heat in
concealed spaces. When inspection holes are made, the TIC should be used to determine if any
heat is present in and around metal gusset plates and C-Joists.
B) Units operating above the fire should use caution, since the TIC may not always detect the
intensity of the fire below. In addition, it may not detect heat or fire where double - 5/8”
plasterboard is used.
C) Unless the fire is minor, or confined to a small area, the primary emphasis for a fire in a
lightweight building under construction is that of an exterior attack. Exterior streams should be
positioned and operated from safe areas outside the collapse zone.
D) When fire is found in a vertical void, the cellar space should be promptly checked for
extension within the limits of safety.
- D
4.1.8 When fire is found in a vertical void, the cockloft/attic space should be promptly
checked for extension within the limits of safety.
15) The presence of smoke pushing at the floor line on the outside of a private dwelling may be
an indication of a fire in a __________. Please fill in the blank?
A) ceiling where the floor is constructed of wood I-beams
B) ceiling where the floor is constructed of metal C-joist
C) ceiling where the floor is constructed of lightweight parallel chord wood truss
D) None of the above
- C
15) Brannigan Chapter 12 Trusses - During a fire the presence of truss floors may be disclosed
by smoke showing through the wall at the floor line. This is less likely in a brick veneered
building.
16) You are operating as the first due engine officer at a fire in a Private Dwelling with the
following CIDS message:
PD 3 STY 25X60 CL4LW-L/W
WOOD JOIST TRUSS ON ROOF AND
ALL FLRS YEAR BUILT 2008
Please choose an incorrect engine company tactic at this type of fire? (Section 4.2)
A) The positioning of the 1st hose-line for a quick knock-down of a contents fire that has not
extended to the structural components is of paramount importance.
B) A 2nd hose-line must be positioned to back up the 1st line.
C) When the 2nd line is needed to address a potential life hazard or is directed by the Incident
Commander (IC) to a location remote from the 1st hose-line, a 3rd hose-line should be
considered as a back-up line.
D) When the fire is of such magnitude that it cannot be quickly knocked down with two hoselines,
then an outside operation must be considered.
- C
4.2.2 A 2nd hoseline must be positioned to back up the 1st line. When the 2nd line is
needed to address a potential life hazard or is directed by the IC to a location
remote from the 1st hoseline, a 3rd hoseline must be positioned as a back-up line.
The IC shall special call an additional engine company for a structural fire in a
building constructed of lightweight materials.
17) Please choose the correct procedure from the list below? (Section 4.3.8)
A) Under no circumstances shall the roof be cut in any peaked or flat roof building of
lightweight construction.
B) Under no circumstances shall the roof be cut in any peaked roof building of lightweight
construction, flat roofs using lightweight construction can be cut with extreme caution.
C) Under no circumstances shall the roof be cut in any flat roof building of lightweight
construction, peaked roofs using lightweight construction can be cut from a Tower Ladder
basket.
D) Under certain circumstances the roof can be cut in a peaked or flat roof building of
lightweight construction.
- A
4.3.8 Cutting the roof and pushing down the ceiling could expose the cockloft area to
additional heat and fire from the top floor. In addition, a saw cut could sever a
structural member causing the failure of one or more trusses/joists. Therefore,
under no circumstances shall the roof be cut in any peaked or flat roof building of
lightweight construction.
18) When the fire is on the top floor of a building where the roof is constructed using
lightweight materials and there is a clear indication that the fire has not entered the cockloft, roof
operations shall be limited to: (Section 4.3.10)
A) Checking the rear and sides of the building.
B) Venting the top floor windows after coordinating with the IC only, and skylights if present.
C) Inspecting HVAC duct vents for unusual heat.
D) All of the above.
Please choose the most correct answer(s) from the list above?
- A, C
18) When fire is on the top floor and there are indications that it has extended to the
attic/cockloft, the IC shall be immediately notified, and members shall not be permitted to
operate on the roof. Any fire present in the attic/cockloft represents the potential for a partial or
complete collapse of the roof.
19) You are operating as the second ladder company officer at a fire in a private dwelling
constructed of lightweight materials on all the floors and the roof. The fire is on the first floor
and you about to proceed to the second floor, you would know to consider which of the
following prior to proceeding above the fire? (Section 4.4)
A) Location of the fire.
B) Extent of the fire.
C) Presence of a life hazard (known only).
D) Position and progress of the 1st and 2nd hose-lines.
- A, C, D
4.4 Floor Above Considerations
4.4.1 Before proceeding above the fire floor, members should determine:
Location, and extent of the fire.
Presence of a life hazard (known or suspected).
Position and progress of the 1st and 2nd hoselines.
19) A known life hazard is defined as follows:
A victim can be seen by the rescuer.
A victim can be heard by the rescuer.
A member has information from a credible source or a person at the scene indicating the location
of the life hazard.
20) In lightweight constructed buildings, an adjustment in strategy and tactics will be required
when a fire has progressed from a contents fire to a fire involving structural components. Due to
the potential failure and early collapse of these lightweight structural components, a proper riskreward
analysis may determine that a planned coordinated interior attack is not justified. Key
size-up indicators for the Incident Commander include: Please choose the correct size-up
indicator(s) from the list below? (Section 4.6.3)
A) Extent of the fire. (light, medium, heavy)
B) Location of the fire (top floor, cellar, void spaces, etc.)
C) Volume of smoke and fire (light, medium, or heavy)
D) Smoke action (pushing, twisting, or rolling under pressure)
21)
- All
20) When size-up determines that the fire involves only the contents and has not extended into
the structural components, standard tactics for private dwelling fires are generally appropriate.
21) You are performing building inspection when you arrive at a construction site where they
are using normal wood joists (2x8s) to support the floors and the ceiling will be detached from
the floors. Would the construction workers be required to fire stop this type of floor every 500
square feet or this requirement only for laminated wood I-beams? (BISP Manual
chapter 5, reference 14.6)
