Members are in the kitchen discussing operations at natural gas emergencies. The members are a little rusty on the subject because they only made one correct point. Which one is correct?
A) Natural gas is delivered to NYC via pipeline at over 1400 psi.
B) Natural gas is regulated down to 300 psi for transmission gas mains.
C) Distribution gas mains run under streets and deliver either high pressure (40 psi), medium pressure (5-20 psi), or low pressure gas (1/2 psi).
D) High and medium pressure gas is regulated down to 1/2 psi before passing through a customer’s meter.
B) Natural gas is regulated down to 300 psi for transmission to gas mains. (Correct) (TB Emergencies 2)
- Gas delivered to NYC at approx 700-1400 psi
- High pressure 60 psi
Medium pressure 3-15 psi
Low pressure 1/4 psi - High and medium pressure gas is regulated down to 1/4 psi before entering customer meters.
Members of your company are operating at a utility gas emergency and take the following actions. Which action is not correct?
A) Upon encountering a white curb valve the member realizes that this valve is plastic and can be easily broken so he closes it gently.
B) Upon encountering an older curb valve the member is required to turn the valve multiple times to close. He knows it may take 7 1/2 to 15 full turns to close but should not turn the valve more than 15 times.
C) To clear an area inside of a structure of leaking gas, the Irons firefighter decides to use the department fan.
D) The Can firefighter decides to stuff a rag in the break of a low pressure gas pipe to stop or greatly diminish the leak.
C) To clear an area inside of a structure of leaking gas, the Irons firefighter decides to use the department fan. (Incorrect) (TB Emergencies 2)
- Department fans are not intrinsically safe and shall not be used during gas leaks.
- Stuffing rags in low pressure gas piping is ok, this won’t work on high pressure pipes.
Utility companies such as Con Edison and Natural Grid may require the FDNY to pull manholes and various other tasks at natural gas emergencies. Of the choices below, which one is correct?

above 100% LEL (explosive environment) DO NOT OPERATE
except for life saving purposes. - Normal oxygen reading = 20.8%
Low oxygen alarm = 19.5%
High alarm = 23.0% - Indoor action lvl = 10% LEL
Outdoor action lvl = 20% LEL
The high rise nozzle is a relatively new piece of equipment utilized by the FDNY and can be implemented by the IC as an alternative strategy at a high rise fire. Which statement regarding the HRN is wrong?
A) It is the responsibility if the 4th due engine to bring the HRN to the Incident command post.
B) Once a window is chosen, remove impediments such as child gates and window bars but leave the window itself intact.
C) A shutoff should be placed two lengths back from the HRN. When repositioning the nozzle have this shutoff closed, them open the nozzle to bleed the line for easier movement.
D) A 1 1/8” MST is attached to the outlet of the HRN. The HRN is checked weekly during MUD and before use.
C) A shutoff should be placed two lengths back from the HRN. When repositioning the nozzle have this shutoff closed, them open the nozzle to bleed the line for easier movement. (Incorrect) (TB Tools 7)
- A shutoff should be placed one length back from the nozzle.
- It is not necessary to remove the window when implementing the
HRN. - If 4th due engine has no HRN the officer will contact dispatch to
learn the identity of the unit carrying it.
At a NFP MD fire that has spread to the cockloft, the Chief of battalion 33 has ordered the cockloft nozzle to be put into operation. This know nothing chief was only correct in one order he gave. Which order was correct?

B) The chief ordered the proby to collect the nozzle from his
battalion vehicle.
C) He told the members that the distance between the top of the ceiling joists to the bottom of the roof joists must be at least 4’ to enable use of the cockloft nozzle.
D) He asserted that a hole in the ceiling approx 3’ x 3’ was sufficient
enough for the nozzle to fit into and operate into the cockloft.
D) He asserted that a hole in the ceiling approx 3’ x 3’ was sufficient
enough for the nozzle to fit into and operate into the cockloft.
(Correct) (TB Tools 7)
- Cockloft nozzle NEVER used as primary attack line.
- Carried by all DIVISION vehicles
- Preferred location = immediately inside the apartment door.
- Top of ceiling joist to bottom of roof joist must be a minimum of 4”

C) Toxicity not over 35 ppm of carbon monoxide.
D) Toxicity not over 10 ppm of hydrogen sulfide.
B) Flammable range not over 1% of the LEL. (Incorrect)
*Not over 10% of LEL. This is our indoor action level. Our action levels are all very low. 10% of LEL is NOT EXPLOSIVE yet at 100% of LEL we have reached the explosive range. Don’t confuse this with percentage of gas in the air.
Which statement does not demonstrate proper technique for use of the high rise nozzle?
A) Supplied by a 2 1/2” hose line, the HRN will produce flows of 200-225 gpm at 50 psi nozzle pressure with water flowing.
B) Once the proper window is chosen and opened, impediments such as window bars and child gates will have to be removed. In most cases it is not necessary to remove the window to operate the nozzle.
C) When repositioning of the HRN is required, the supply line should be shut down at the shutoff located 1 length back and the nozzle operated to bleed the line.
D) Once in position the officer supervising the nozzle operation will order water started and nozzle to be operated.
D) Once in position the officer supervising the nozzle operation will order water started and nozzle to be operated. (Incorrect)
*The nozzle will not be operated until the IC has given approval.
