Question 31

Question 31:
According to the Loft Bulletin, at ______ degrees Fahrenheit, cast-iron loses _____ % of its original strength.
A: 800, 42

B: 800, 58

C: 1100, 42

D: 1100, 58

Answer 31

Question 31:
According to the Loft Bulletin, at ______ degrees Fahrenheit, cast-iron loses _____ % of its original strength.
A: 800, 42

B: 800, 58

C:✘1100, 42

D:✔1100, 58

Explanation:
Loft Building Fires
The strength lost is cumulative and never regained
**Cast-Iron columns are not designed to withstand an eccentric load
**When properly cast, these structural members will withstand a great deal of thermal stress. The statement that all cast-iron columns exposed to fire will shatter when cooled by a hoseline is a myth. However, if an improperly cast column is cooled by a hoseline it can contract disproportionately leading to potential failure
*** Iron fibers (like steel) when heated elongate or extend the column. A structural cast-iron column, however, unable to move will crack

C: As a last resort, use hi-expansion foam to control the cellar fire.
D: When conditions indicate, use cellar pipes and distributors through holes in the floor.

C:✔ 2, 3, & 4 only indicate breached packages

D: 2 only indicates breached packages

Explanation:
ERP Addendum 4 - Radiation pg 33
2.5.3 - If levels of radiation exceed the Transport Index, the integrity of the package may have been compromised or breached.
2.5.4 - The TI applies to levels of Gamma Radiation only. Readings of Alpha or Beta particles indicate the package may have been breached or the shielding compromised. (#2)
2.5.5 - The Transport Index of a package should not exceed 10 mr/hr (#1 is 10 indicating no breach, #4 is 5 R indicating breach)
2.5.6 - The Transport index of a shipment should not exceed 50 mr/hr
(#3 states 100)

A: One fan can provide the proper pressure in a stairwell up to 10 stories, depending on conditions.
B: Two fans will pressurize a 40 story building when properly positioned.
C: If the fire floor is above the 10th floor, or additional pressures are required to maintain the stairwell free of smoke, a second fan must be brought to three floors below the fire floor and set up.
D: Proper positioning when pressurizing the stairwell in a high-rise building has the fan set up 6 to 8 feet back, at an 80 degree angle.

Question 36

Question 36:
The incorrect statement in regards to Stack Effect can be found in which choice?
A: The “Stack Effect Neutral Pressure Zone” will be found near the center of the building that experiences no horizontal air exchange at all (air will not be pulled into or pushed out of an opening or pulled into or pushed out of a floor due to stack effect)
B: Shorter buildings will experience a more powerful Stack Effect because more air will be moving a shorter distance inside the building
C: The magnitude of the Stack Effect will be dictated by the size of the temperature differential between the interior of the building and the exterior environment and the height of the building
D: Stack Effect will be more prominent in extreme weather; when air conditioning or heating systems make the temperature inside the building remarkably different from the outside temperature

A: The “Stack Effect Neutral Pressure Zone” will be found near the center of the building that experiences no horizontal air exchange at all (air will not be pulled into or pushed out of an opening or pulled into or pushed out of a floor due to stack effect)

B:✔Shorter buildings will experience a more powerful Stack Effect because more air will be moving a shorter distance inside the building

D: Stack Effect will be more prominent in extreme weather; when air conditioning or heating systems make the temperature inside the building remarkably different from the outside temperature

Explanation:
Fire Dynamics sec 1.4, 1.4.3 and 1.5 (2019)
TALLER buildings will experience a more powerful Stack Effect because more air will be moving over a longer distance inside the building. Also, the presence of large vertical shafts (stairways, elevators, compactors, etc.) will contribute to the strength of the Stack Effect
**This condition can cause smoke and fire gases to bypass several floors near the center of the building (near the stack effect neutral pressure zone), only to be pulled into floors somewhere above or below the center of the building depending on the direction of the stack effect

Question 37

Question 37:
Basic knowledge of the Buckeye Pipeline is essential to units operating properly at pipeline incidents. Of the following choices, which contains incorrect information?

B: There are some above-ground valves that may require shutting down by Fire Department personnel. These valves are located behind locked metal wire fences openable with a 1620 key.
C: There are four Buckeye Pipeline locations that are equipped with intruder alarms. If units need to enter these locations for any reason other than an emergency response (i.e. drills or training) the Buckeye Pipeline Control Center must be notified through the Borough Dispatcher after entry.
D: The Hazardous Vapor Detection Alarm resembles a fire alarm strobe outside of these locations.

Explanation:
There are four Buckeye Pipeline locations that are equipped with intruder alarms. If units need to enter these locations for any reason other than an emergency response (i.e. drills or training) the Buckeye Pipeline Control Center must be notified through the Borough Dispatcher PRIOR to entry.
B Note: Due to increased security measures from the Department of Homeland Security, if an intruder alarm is received without prior notification, this will cause an emergency shut down of the pipeline.
C Note: Members must use extreme caution at these locations as they are potentially entering a flammable atmosphere. The IC must utilize Haz-Mat Co. 1, a Haz Mat Tech Engine or a Squad company with metering capabilities to confirm that there is not an accumulation of flammable vapors.
