Question 2:
Which property of natural gas is listed incorrectly?
A: Comprised mainly of methane but also contains propane, ethane and nitrogen.
B: It is a hazardous material classified as a Class 2, Division 1 substance. It contains high stored energy and is extremely flammable.
C: Depending on the mixture, the explosive range is 5% - 15%.
D:Colorless, but has a natural smell of “rotten eggs”.
Explanation:
Colorless and ODORLESS; however, to aid in detection, mercaptan is added to natural gas as an odorant.
Be aware of the change…it is now a “ROTTING” smell…NOT “rotten eggs”
D) Note: Mercaptan can be masked by other odors, stripped by chemicals or removed as natural gas passes through material such as soil. In addition, members operating in a gas environment can become desensitized to the smell, giving the false impression that the natural gas condition is no longer present.

Question 3:
You are working the 9x6 tour in L-100 when you receive a ticket to respond 2nd due for a gas leak in apt 2D on the 2nd floor of a 100x100 “H” type MD. During your response (non-response mode), you are flagged down for a 2 car accident with no injuries. The most correct action for you to take at this point is to?
A: Notify dispatcher to take you off gas leak and assign L-100 to accident
B:Give verbal alarm to dispatcher of accident and proceed to gas leak
C: Proceed to gas leak and notify dispatcher after going 10-8 from gas leak
D: Have someone involved in accident call the 911 system to have other units respond to accident
Explanation:
Communications ch 6 sec 6.5.2.B
In the event the unit is responding to another alarm and it is evident human life is not in jeopardy at the scene of the verbal alarm, the unit shall proceed to the original alarm after transmitting radio notification of a verbal alarm to dispatcher and receiving acknowledgement
Question 4:
Of the following properties of natural gas, which is not entirely correct?
A:It is slightly lighter than air.
B: It is non-toxic, but in sufficient quantity, natural gas can displace oxygen in an enclosed space and cause asphyxiation.
C: When natural gas ignites, it undergoes a rapid increase in volume. If confined, the pressure, due to the volume change, will create an explosive force. A greater amount of gas indicates greater destructive potential; two cubic feet of natural gas has the approximate energy potential of 1 pound of TNT.
D: When unconfined (outdoors), natural gas will burn rapidly, without triggering explosive pressure.
Explanation:
It is SIGNIFICANTLY lighter than air.

Question 6:
Which choice below contains incorrect information regarding NYCs natural gas system infrastructure?
A: Con Edison Gas distributes natural gas to Manhattan, the Bronx, and in Queens, generally north of the Grand Central Parkway.
B: National Grid distributes gas to Brooklyn, Staten Island and in Queens, generally south of the Grand Central Parkway.
C:Gate Stations have remote monitoring by the Utility Company’s Gas Control Centers and will always be staffed with on-site personnel. Any event in these facilities should be considered an industrial facility emergency and actions should be limited to a rapid, primary search of the facility.
D: From Gate Stations, natural gas is delivered via Transmission Mains to area Regulator Stations which can have above-ground and/or vaulted equipment. At Regulator Stations, pressure is reduced and the gas is routed to various customers via Distribution Mains.
Explanation:
Gate Stations have remote monitoring by the Utility Company’s Gas Control Centers but GENERALLY have NO permanent on-site personnel. Any event in these facilities should be considered an industrial facility emergency and actions should be limited to LIFE SAVING and PROTECTING EXPOSURES until the Utility Company has been consulted.

Question 7:
The most correct way to perform Noxious Stimulus Triage (NST) when encountering multiple unconscious victims can be found in which choice?
A: Check breathing to determine level of responsiveness
B: Check pulse to determine level of responsiveness
C: Check circulation to determine level of responsiveness
D:Nudge victim to determine level of responsiveness
Explanation:
Haz-Mat 5 sec 6.2.2
NST- A triage method used when encountering multiple unconscious victims. Member nudges victim to determine level of responsiveness
Question 8:
Natural gas is piped to customers along Distribution Mains which may be high, medium or low pressure and Regulator Stations reduce pressure between Distribution Mains of different types. Which choice below contains incorrect information regarding these mains?
A: High pressure Distribution Mains are made of steel and are generally installed below major roads.
B:Medium and low pressure Distribution Mains are made of steel or plastic; they will never be made of cast iron as it is prone to corrosion and failure, being brittle with low tensile strength.
C: High and medium pressure Distribution Mains have control valves that are exercised (partially) on a schedule to ensure working order. These valves are generally found near street corners, but may also be located along the street or on the sidewalk.
D: Low pressure (¼ psi) Distribution Mains generally do not have valves and isolating sections of low pressure Distribution Mains requires plugging or “squeezing off” the pipe while still under pressure (live). Only the Utility Company can safely plug or squeeze-off Distribution or Service Mains due to spark hazards.
Explanation:
Medium and low pressure Distribution Mains are made of steel, plastic, or, if older, cast iron. Cast iron pipe is currently being replaced as it is prone to corrosion and failure, being brittle with low tensile strength.
C) Note: Main valve covers are larger than curb valve/service valve covers to allow servicing and may be round or square.

Question 9:
In order to be an effective officer when operating at the scene of a vehicle extrication, there are several safety precautions you must enforce. Choose the incorrect safety precaution.
A:Cutting the hydraulic pistons or rods on a hatchback style vehicle shall always be attempted from the top first
B: Whether using the spreaders or cutters always remove the top hinge first (door)
C: An area of safety measuring the fully opened length and width of the jaws must be maintained
D: The hydraulic hose lines may be coupled or uncoupled with the power unit running, provided the bypass valve is in the backward or dump position
Explanation:
Emergency Procedure vehicle Disentanglement and Extrication sec 14
A- Avoid cutting through hydraulic pistons or rods on hatchback style vehicles…14.3 D- 14.13
Question 10:
Two firefighters discussing the natural gas system supply infrastructure made an incorrect comment which can be found in which choice?
A: Gas service is the piping supplying individual buildings; gas service pipe generally runs at right angles off of the Distribution Main, into the building. There is usually a curb valve/service valve (below grade) or an exterior gas service valve (above grade) between the Distribution Main and the building.
B: On the National Grid “Long Service” system, the curb valve/service valve is sometimes located across the street from the building it supplies, and may be found in the street. This type of curb valve/service valve can be identified by an arrow cast into the cover pointing to the building it supplies.
C: Some gas service piping supplies gas to the building without having a curb valve or service valve. A “NC” stamped on a tag near the service meter indicates there is no curb valve or service valve. An “EFV” stamped on a tag near the service meter indicates an “excess flow valve” exists in line on the service pipe and the EFV should limit or stop excess flow down pressure from it.
D:Exterior Gas Service Valves control the supply of gas to meters installed on the outside of buildings; if an exterior gas service valve is present, a curb valve/service valve will always be found in line. Head of Service Valves control the supply of gas to meters installed on the outside of buildings.
Explanation:
Exterior Gas Service Valves control the supply of gas to meters installed on the outside of buildings; if an exterior gas service valve is present, NO curb valve/service valve is required. Head of Service Valves control the supply of gas to meters installed on the INSIDE of buildings.

Question 14:
All BCs should be familiar with Fire Department strategy for a “Major Gas Emergency.” Of the following choices, which is incorrect?
A: When a response elevates to become a “Major Gas Emergency,” FDNY strategy should focus on securing life safety (evacuation).
B: “Serious” damage to “major” components of the gas infrastructure (i.e., a Master Meter servicing many appliances, gas service pipe, Main Valves, Distribution Mains, etc.) is indicative of a Major Gas Emergency and may require changing from a simple mitigation strategy to one that emphasizes all efforts on securing life safety.
C: Gas leaking or present inside of a wall or void in a structure is indicative of a Major Gas Emergency and may require changing from a simple mitigation strategy to one that emphasizes all efforts on securing life safety.
D:Gas present in a single subsurface structure (manhole, sewer, etc.) is indicative of a Major Gas Emergency and may require changing from a simple mitigation strategy to one that emphasizes all efforts on securing life safety.
Explanation:
Gas present in TWO OR MORE subsurface structures (manhole, sewer, etc.) is indicative of a Major Gas Emergency and may require changing from a simple mitigation strategy to one that emphasizes all efforts on securing life safety.

Question 16:
Apparatus positioning is a critical component of the Department’s response to gas emergencies. Which choice below contains incorrect information?
A:New dispatch policy requires the FDNY dispatcher to notify the Gas Utility Company upon receipt of the alarm (before FDNY arrival on the scene). The Gas Utility Company is required to give an estimated time of arrival (ETA) and their response time is typically within 20 minutes.
B: If a strong odor is present on approach, stop and meter the area. If the meter displays 10% of the LEL, this may indicate a potentially serious leak and may require treating the incident as a Major Gas Emergency.
C: First-arriving apparatus should not be positioned in front of the reported leak location and should avoid positioning over manholes and sewers.
D:Additional units shall stage at street corners, and only enter into the block when appropriate.
Explanation:
The Gas Utility Company is required to give an estimated time of arrival (ETA) and their response time is typically within 30 minutes.
