LT PKG EXAM #23 Flashcards
Question 1:
When operating in or on a roof of a building with solar panels there are many safety and health concerns to consider. Choose the correct safety/ health concern.
A: When power is shut at the main building panel, electrical energy will be considered removed throughout the building including the solar panels
B: Utilizing disconnects ahead of or after the inverter ensures electric current is removed from the solar panels
C: Combiner boxes should be opened by firefighters in an attempt to shutdown the solar panels
D: Lightening flashes occurring at night can energize the solar panels
Answer: D
Explanation:
A- Even though the electrical power from the utility grid can be disconnected at the main distributeion panel, electrical energy is still present as long as the PV array is connected
B- Utilizing disconnects ahead of or after the inverter still does NOT eliminate the electric current coming from the solar panels
C- Combiner boxes should NOT be opened by firefighters in an attempt to shutdown the solar panels

A: 25 ft
B: 50 ft

Question 3:
The engine officer has many responsibilities at a structural fire. Which responsibility is not entirely correct?
A: Before calling for water, the engine officer should confirm that sufficient hose has been stretched and flaked out and confirm with the nozzle and back-up firefighters that they are ready for the line to be charged.
B: The engine officer should ensure each firefighter is properly equipped with all required PPE and that their SCBA is donned and in use.
C: The engine officer should ensure the line is properly bled before the attack begins. At standpipe operations, a long bleed will be necessary to allow the control firefighter to properly set the operating pressure at the standpipe outlet.
D: The long bleed is not necessary when a 2 ½” hoseline is stretched from the apparatus. In this case, a short bleed is preferred.
Answer: D
Explanation:
D) The long bleed WILL ALSO BE NECESSARY when a 2 ½” hoseline is stretched from the apparatus. In this case, the low operating pressure may be below the preset of the Pro-Pressure Governor. This will require the ECC to set the pressure manually and necessitate a long bleed by the nozzle firefighter to allow the pressure to be properly set.
Note: The engine officer should ensure the line is properly bled before the attack begins. This is to confirm water at the nozzle, allow air to escape the hoseline, and to allow for the proper setting of the operating pressure.

Question 4:
When submitting a CIDS card, the following information must be transmitted in the proper order. Which choice is CORRECT?
A: Occupancy, Description of Building, FD Designation, Description of Dangerous, Hazardous or Unusual Condition, Minresp.
B: FD Designation, Occupancy, Description of Building, Description of Dangerous, Hazardous, or Unusual Condition Minresp
C: FD Designation, Occupancy, Description of Building, Minresp, Description of Dangerous, Hazardous, or Unusual Condition.
D: Occupancy, FD Designation, Description of Building, Description of Dangerous, Hazardous, or Unusual Condition, Minresp.
Answer: B
Explanation:
COMMUNICATIONS MANUAL – CHAPTER 4 – CIDS
B IS CORRECT – The ECIDS application will assist in placing the information in the CORRECT order, however, this has been a question used on multiple exams in different forms. FD DESIGNATION, OCCUPANCY, DESCRIPTION OF BUILDING (Height, Dimension, Class in that order), DESCRIPTION OF HAZARD, MINRESP is the only order. 4.5.3B
Question 5:
When using Positive Pressure Fans (PPV) to pressurize the attack stairwell, all stairwell doors in the attack stairwell shall be kept closed. However, the pressure delivered to the attack stair by the PPF will be great enough to allow a number of stairwell doors in the attack stair to be open to remain effective. The correct number of doors can be found in which choice?
A: 4
B: 3
C: 2
D: 1
Answer: B
Explanation:
The pressure delivered to the attack stair by the PPF will be great enough to allow for up to 3 stairwell doors to be open and pressurization to remain effective. However, all members should understand that keeping as many doors closed as possible is the goal. Members are permitted to move from one area to another as long as they remember to close the stairwell door behind them.

Question 6:
Which natural gas tool is used to determine the amount of gas present in an area? How does it display the levels of gas?
A: The natural gas detector; % of gas in air
B: The natural gas detector; % of LEL
C: The CO meter; % of gas in air
D: The natural gas meter; % of LEL
Answer: D
Explanation:
THE METER SHOWS THE % OF THE LOWER EXPLOSIVE LIMIT (LEL). THE EXPLOSIVE RANGE OF GAS IS 5%-15%. THEREFORE, THE LEL IS 5%.
FOR EXAMPLE, 5% GAS IN AIR WOULD BE 100% OF THE LEL ON THE GAS METER. 2.5% GAS IN AIR WOULD BE 50% OF THE LEL ON THE GAS METER AND SO ON…

Question 7:
Your unit is the first arriving aerial ladder at a serious fire in an isolated building where roof access and egress via conventionally positioned aerial ladders is endangered by the serious fire condition. Which choice below would be an incorrect action in this scenario?
A: Consider placing the aerial ladder at a safe angle to the least exposed sidewall of the building.
B: Placing the apparatus on the sidewalk is permitted to obtain the necessary position.
C: Under no circumstances should the aerial ladder be placed in the cantilever position.
D: Members should ascend or descend at well spaced intervals.
Answer: C
Explanation:
C) Initially place the aerial ladder in the cantilever position with the tip fairly close to the building.
C Note: Do this so that when placed under load it will either not touch or barely touch the wall. This should eliminate any twisting stress.

Question 11:
Proper use of elevators in high rise fireproof multiple dwellings (HRFPMD) is essential for successful operations in these buildings. Of the following choices, which is incorrect?
A: Some elevators open directly into apartments or foyers while others open onto a small landing or foyer with only two doors, each serving one apartment. There are no stairs or other means of egress from this type of foyer and these types of elevators should not be used by members.
B: A service/freight elevator shall not be used until it has been evaluated and declared safe for use by the company officer. Once deemed safe for use, members shall take the service/freight elevator to two floors below the fire and take the stairs to the correct floor.
C: Standpipes are usually found in the service stairway. Service stairs may be locked on the first floor with a wire mesh door that permits egress from upper floors but no entry into the stairs from the first floor. These mesh doors are easily forced.
D: After all units are in position, and two elevators are available and serviceable, maintain one elevator on standby in the lobby and one on the floor below the fire.
Answer: D
Explanation:
D) After all units are in position, and two elevators are available and serviceable, maintain one elevator on standby in the lobby and one TWO FLOORS below the fire.
A Note: In these buildings, the service/freight elevator will usually service all floors.
C Note: This information, and location of the service/freight elevator and service stairs, should be entered into the CIDS program.

D: Although wind impacted fires are typically associated with fires in fireproof multiple dwellings, they can occur at fires in other structures, excluding private dwellings.
Answer: A
Explanation:
B) Wind introduces large amounts of oxygen and causes forced CONVECTION of the fire area and burning materials.
C) “BLOW TORCHING” is the appropriate description of what can occur when fire conditions are impacted by the wind. Wind can dramatically change a fire in seconds.
D) Although wind impacted fires are typically associated with fires in fireproof multiple dwellings, they can occur at any fire INCLUDING those in PRIVATE DWELLINGS.
B Note: The fresh air moving with wind currents at Wind-Impacted Fires cause significant changes to fire development, fire travel and smoke movement.
D Note: Wind can also have significant impact on non-structural fires such as brush fires or large area rubbish fires.
