Question 12:
A BC conducting drill with local units on gas emergencies had to address which incorrect comment made?

A: An “Explosion Profile” is the size-up of a building’s explosion potential based on the current amount of natural gas and gas energy within the structure. To determine this, the amount of natural gas present and the size of the area the gas is accumulating in should be estimated.

B: A 10-75 and 10-80 Code 1, specifying a “Major Gas Emergency,” should be transmitted to the dispatcher when an incident is determined to be a Major Gas Emergency.

C:The IC may modify the assignment assigned on a 10-75 and 10-80 Code 1 for a “Major Gas Emergency” to meet incident needs after careful consideration and consultation with the Rescue Battalion via cell phone (preferred) or 800 MHz radio.

D: When a 10-75 and 10-80 Code 1 specifying a “Major Gas Emergency” is transmitted, the IC should also transmit the location of the designated Command Post and Staging Area.

c Explanation:
The IC may modify the assignment assigned on a 10-75 and 10-80 Code 1 for a “Major Gas Emergency” to meet incident needs after careful consideration and consultation with the HAZ-MAT BATTALION via cell phone or 800 MHz radio (PREFERRED).

Question 13:
Sound strategy at gas emergencies can be found in which choice below?

A:The officer not put to work by the IC should be the Safety Officer until relieved by the assigned Battalion Chief designated as the Safety Officer.

B:As soon as possible, the IC should transmit to the dispatcher a concise description of the conditions, % LEL of meter readings taken with the locations, and tactics implemented.

C: Stopping a leak from a high pressure main will generally require the Utility Company construction crew plug or clamp (squeeze) the pipe to interrupt natural gas flow. The request should be made as early as possible to allow for the long reflex time for this resource.

D: Medium and low pressure natural gas mains present much greater risk as large amounts of gas will escape. Stopping a leak generally involves the Utility Company finding and operating the correct upstream valves to interrupt the flow of natural gas.

b Explanation:
A) The officer not put to work by the IC should be the STAGING AREA MANAGER until relieved by the assigned Battalion Chief designated as the Staging Area Manager.
C) Stopping a leak from a LOW PRESSURE main will generally require the Utility Company construction crew plug or clamp (squeeze) the pipe to interrupt natural gas flow. The request should be made as early as possible to allow for the long reflex time for this resource.
D) MEDIUM and HIGH pressure natural gas mains present much greater risk as large amounts of gas will escape. Stopping a leak generally involves the Utility Company finding and operating the correct upstream valves to interrupt the flow of natural gas.

Question 14:
You arrive at a gas emergency where a backhoe damaged a gas line in an excavation located in the middle of a residential neighborhood. Which tactic implemented below would be considered incorrect?

A: Check subsurface structures and surrounding basements/cellars for natural gas infiltration from the original leak, or secondary leaks as soon as possible.

B:Set up precautionary hose lines to control possible extension in case the natural gas ignites. Operate a hoseline into the excavation to protect against ignition and hasten isolation and repair.

C: Large caliber streams should be considered as their reach and volume is appropriate for defensive use. If the natural gas ignites, do not extinguish the fire but cool adjacent structures as necessary to prevent extension from radiant heat.

D: Locate valve locations if outside of the potential blast zone and create access for the Utility Company if blocked by vehicles, etc. (consider floor jacks, Hurst tool chains, NYPD Towing, resources through NYCEM, etc.) Relay valve identification numbers and locations to the Utility Company if representatives are not yet on sce

b Explanation:
AVOID operating into the excavation, as water accumulation here can impede isolation and repair.
Note: It is possible to have a natural gas leak where the backhoe was operating, another leak at the building line or in the building, and still another one at a coupling or where the service pipe connects to the Distribution Main. These additional leaks can go unnoticed and accumulate to explosive levels.
EP Gas 8 1

15

Question 15:
Which choice below displays an incorrect tactic for a major subsurface gas leak?

A:Use meters to determine how much natural gas has accumulated. From this, an estimate can be made as to the location/size of the potential blast zone; evacuate this area, keeping all personnel, except for trained Utility Company Personnel, outside of the potential blast zone.

B: Establish the potential blast zone and continue to monitor the perimeter for changes. Mark the potential blast zone with red, “DANGER DO NOT ENTER” tape and announce the potential blast zone boundaries over the handie-talkie and Department Radio.

C: Meter readings should be taken at subsurface structures (sewers and manholes) as natural gas may travel along sewer runs, and electric, gas or water conduit/pipe. Gas from a leaking pipe may travel some distance before finding a place to surface as pavement, snow or frozen ground can trap it underground.

D: As rapidly as possible, surrounding below-grade areas of adjacent buildings should be surveyed with meters. Natural gas may pass some buildings with little or no infiltration but enter others via points of entry and wall cracks. Continue to monitor exposures throughout the operation.

a Explanation:
evacuate this area, keeping ALL personnel (including responders and Utility Company personnel) out of the potential blast zone except for direct, lifesaving efforts.

Question 16:
A Company Commander drilling with his members on interior gas leak procedures made which incorrect statement?

A: If the Natural Gas Meter displays any readings at the building entrance/first floor, the Ladder Company Inside Team should go directly to the basement/cellar to investigate. Do not delay by going to a caller on an upper floor.

B: If the leak is found and can be controlled by a valve or, on low pressure service (or medium/high pressure service after the service regulator) by tapping/plugging, then do so.

C: If the leak is found and levels can be kept at less than 80% LEL by venting, you may continue to operate.

D:If levels can be kept at less than 80% LEL, remove ignition sources (shut breakers, pull fuses, shut off gas appliances, etc.) This may be done from an area whether or not it is in the explosive range.

d Explanation:
If levels can be kept at less than 80% LEL, remove ignition sources (shut breakers, pull fuses, shut off gas appliances, etc.) ONLY if this can be done from an area not within the explosive range.

Question 17:
Your unit responds to a report of a gas leak inside of a building but the location of the leak cannot be found. Which consideration below is incorrect?

A: If the leak is not found, investigate the structure’s natural gas meters; if one is showing high gas flow, shut it using the Meter Valve, Head of Service Valve or curb valve/service valve. When possible, always shut the valve closest to the leak.

B:Treat the affected area as a “Potential Blast Zone” if levels cannot be limited to less than 20% LEL by venting and the leak cannot be found and there are indications the leak is coming from an outside, subsurface source.

C: The size of the potential blast zone shall include the area likely to be affected by structural collapse. This zone will be determined by the Incident Commander and identified by red, “DANGER DO NOT ENTER” tape.

D: Utility Companies and FDNY Haz-Mat Company 1, Haz-Mat Technician Units and SOC Support Ladder Companies are equipped with detectors designed for detecting natural gas in voids.

b Explanation:
Treat the affected area as a “Potential Blast Zone” if levels cannot be limited to less than 10% LEL by venting and the leak cannot be found and there are indications the leak is coming from an outside, subsurface source.
EP Gas 8 3

18

Question 18:
Many restrictions come with the designation of an area as a “potential blast zone.” Which choice below is incorrect?

A:Apparatus should not be located within the potential blast zone; members may temporarily enter a potential blast zone to move apparatus. The number of members and time spent operating in the potential blast zone should be kept to a minimum and allow for rapid evacuation.

B: The potential blast zone will include streets, yards or alleys on all sides of the involved building. Exposures may be included in the potential blast zone if likely to be affected by an explosion.

C: Other agencies should be prevented from entering the potential blast zone unless they are involved in direct, life-saving procedures; this includes Utility Company personnel.

D: Extreme care shall be exercised before re-entering a building that was in the potential blast zone. Natural gas levels in surrounding areas should be absent or low as the potential blast zone is redefined based upon all information gathered before allowing any members, including Utility Company personnel, back in.

a Explanation:
Apparatus should not be located within the potential blast zone; however, do NOT enter a potential blast zone to move apparatus. The number of members and time spent operating in the potential blast zone should be kept to a minimum and allow for rapid evacuation.
EP Gas 9

19

Question 19:

There are few reasons for a member to enter the potential blast zone at a gas emergency. Which choice below is incorrect?

A: The quick evacuation of likely occupants is a permissible tactic inside of the potential blast zone. This should be done with minimum exposure of members and minimum time spent in the potential blast zone.

B: Removing ignition sources and venting are not options within the potential blast zone.

C: Reconnaissance is not a permissible reason to be inside of the potential blast zone.

D:It is permissible to enter the potential blast zone for purposes of power removal.

d Explanation:
No amount of reconnaissance, venting or power removal is worth a first responder’s life. Other than rapid evacuation no other actions inside of the potential blast zone should be warranted.
EP Gas 9.1

20

Question 20:
Safety inside of the potential blast zone at a gas emergency is paramount. All choices below contain correct information regarding safety in this area except?

A: Do not use door bells as this may trigger an electric spark; knock on doors.

B:Static electricity can cause ignition. When knocking on doors, strive to stand on doormats outside of apartments; likewise, traversing across carpeted areas is preferable to hard surfaces.

C: Known life hazards and people needing assistance should be helped using standard removal techniques. Minimize the time spent inside of the potential blast zone.

D: Ensure only intrinsically safe equipment is utilized.

b Explanation:
AVOID standing on doormats inside of the building; likewise, AVOID traversing across carpeted areas.
EP Gas 9.1.1

21

Question 21:
Currently, the only FDNY-issued powered equipment that are intrinsically safe (can be used in a potentially explosive atmosphere) include all of the following except?

A: Handie-talkies

B: Flashlights issued by the FDNY

C:Thermal Imaging Cameras

D: Natural Gas Detectors and Natural Gas Meters

c Explanation:
Do not use any powered equipment that is not intrinsically safe inside of the potential blast zone. Thermal Imaging Cameras, Ventilation Fans, Cell Phones and Megaphones are not intrinsically safe.
Megaphones may be used OUTSIDE of the potential blast zone to issue instructions to the public.
As a precaution, intrinsically safe equipment should be powered on in a clear environment and remain on until returned to a clear environment.
EP Gas 9.1.2

22

Question 22:
One tactic employed at a gas emergency is “rapid evacuation” which will allow members to locate and rescue civilians from an explosive environment, while limiting their exposure to potential extreme hazards. This is significantly different from primary searches conducted at fires and is accomplished with as few members in the potential blast zone as possible to cover the greatest area, and exit the potential blast zone in the shortest time possible. Which choice below contains incorrect information regarding this tactic?

A: Evacuation should be via an available stairway; elevators should not be used.

B:It is conducted by knocking on doors and moving from door to door to alert occupants; the intent is to alert occupants to self-evacuate. If no one answers the door to an area or apartment, members should employ forcible entry procedures.

C: Assistance can be provided to people with special needs or those requiring assistance.

D: Occupants should be notified there is potential for a natural gas explosion and they are not to turn on lights or use cell phones or any other electronic devices and must evacuate immediately by orders of the Fire Department.

b Explanation:
If no one answers the door to an area or apartment, members should MOVE ON TO THE NEXT DOOR. When forcible entry is REQUIRED in an explosive environment it should be accomplished using equipment and techniques that will limit the chance of causing a spark.
EP Gas 9.1.3

23

Question 23:
Which consideration below is incorrect regarding the Department’s “rapid evacuation” tactic at a Major Gas Emergency?

A:When required, conventional forcible entry involving the use of an axe to strike the Halligan should be employed. Do not use hydraulic forcible entry tools (i.e. Hydra-Ram) due to the potential for sparks to be created.

B: In structures with elevators, occupants should be instructed to use the stairs and not the elevators unless the situation makes it impractical (e.g., gas leak on an upper floor of a highrise residential building where FDNY members utilize elevators to evacuate civilians). Elevators in the potential blast zone are NOT to be used by civilian or FDNY personnel; electric arcs are created whenever they are activated by the call button or signaled to move.

C: The IC should consider the evacuation of all buildings in proximity to the incident location when necessary. If these building are not located in the potential blast zone, operations such as routine forcible entry, searches, venting and power removal can be conducted as necessary.

D: It is recommended that members quickly meter sewers, manholes and cellars as they retreat from the original operating area after evacuating occupants.a a 

a Explanation:
Conventional forcible entry involving the use of an axe to strike the Halligan is NOT permitted. Entry SHOULD be conducted with the use of the adz end of the Halligan to gap and force the door and/or with the use of the hydraulic forcible entry tool (Hydra-Ram).
C) Note: In addition to buildings, streets, sidewalks, public spaces, transit facilities, etc., may need to be evacuated as a precaution and to clear areas for Utility Company construction crews.

Question 24:
Which tactic below is incorrect when operating at a Major Gas Emergency?

A: Use plain-speak in preliminary and progress reports concerning the extent of the evacuation required and the need for assistance from NYPD, NYCTA, MTA, etc. NYCEM may be contacted directly to initiate/coordinate additional non-Fire Department resources.

B:2 1/2” hose and large caliber streams are appropriate for defensive positions and will allow greater reach. Fog streams should be used to assist in the dissipation of natural gas venting outside of a structure.

C: The Utility Company may need to “plug” or “squeeze” a pipe with natural gas under pressure to stop a leak when a working valve is not available. When required and consistent with safety, a charged fog hoseline may be used to protect workers placing the plug or operating the clamp.

D: At all major natural gas leaks, notify the dispatcher to have the appropriate Electric Utility Company respond and request an ETA.

b Explanation:
Fog streams should NOT be used to dissipate natural gas venting outside of a structure; LET THE GAS VENT NATURALLY.
C) Note: In all cases, the IC has the responsibility and authority to disapprove this tactic if it places Utility Company personnel or FDNY members at risk. Consult with the Utility Company to consider risks and options.
EP Gas 9.2.1, 9.2.2

Question 25:
Discretion must be used when considering power removal at a major gas emergency. Of the following choices, which contains incorrect information?

A: Power cannot be removed from the potential blast zone without introducing the risk of ignition. Power removal always causes an arc at the point/location that power is removed.

B:If FDNY members can remove power from the area of the leak before natural gas readings reach 80% LEL, it should be done. In order to determine this, explosive readings must be taken wherever the highest concentration of natural gas has accumulated in the building which will always be at the source of the leak.

C: After evacuation, and upon consultation with the appropriate Utility Companies, the IC may consider allowing the Utility Company to cut power remotely from a utility pole or manhole, even if natural gas levels are in the explosive range if all persons remain withdrawn from the potential blast zone and the location from which the Utility Company is cutting power is not located within the potential blast zone.

D: When power is removed, automatic generators, battery back-up burglar alarms, battery back-up hardwired smoke detectors and uninterrupted power supply units for electronics, when present, create small arcs when they transfer from electric power to their alternate.

b Explanation:
If FDNY members can remove power from the area of the leak before natural gas readings reach 80% LEL, it should be done. In order to determine this, explosive readings must be taken wherever the highest concentration of natural gas has accumulated in the building which is USUALLY, BUT NOT ALWAYS, near the source of the leak.
EP Gas 9.2.2

26

Question 26:
When considering power removal at a major gas emergency, the IC would be correct to take into account the information in all choices below except?

A: If power can be removed from the area of the leak before natural gas readings reach 80% LEL, it should be done. Explosive readings must be taken wherever the highest concentration of natural gas has accumulated in the building and this is usually, but not always, near the source of the leak.

B: Readings solely taken in an area remote from the leak cannot be used to determine it is safe to cut power.

C: If any readings display levels of 80% LEL or greater, the opportunity to cut power has expired.

D:When unable to locate the source of the leak, it is always safer to shut power.

d Explanation:
When unable to locate the source of the leak, DO NOT shut power.
EP Gas 9.2.2

27

Question 27:
Locating the correct valves is a crucial component to controlling a major gas emergency. Which choice is incorrect?

A: When conditions permit, units may assist the Utility Company in locating valves and valve covers.

B: Main valves have identification codes either on the collar underneath the valve cover or on a tag under the cover. These codes should be relayed to the Utility Company Control Center and Utility Company members on the scene.

C:FDNY members should be reminded to only operate valves on the supply side of the curb valve/service valve.

D: The IC may be able to receive the general location of main valves by contacting the Utility Company’s Control Center. Access problems (vehicles, dumpsters on valve covers, etc.) can be identified and resolved early.

c Explanation:
FDNY members should be reminded NOT to operate any valve on the supply side of the curb valve/service valve (i.e.; main valve).
EP Gas 9.2.3

28

Question 28:
Which ventilation tactic below is not in accordance with Department procedures when operating at a major gas emergency?

A: If previous ventilation efforts have failed to prevent the area from becoming a potential blast zone (80% or more LEL gas leak location known or 10% or more LEL gas leak location unknown) then the emphasis should be on rapid evacuation, not ventilation.

B:It is generally safe for members to operate in an environment with high concentrations of natural gas if these levels are above the Upper Explosive Limit (UEL) as these areas can be considered “too rich to burn.”

C: Natural ventilation can be accomplished by rapid evacuation teams as they move through buildings. Venting windows and doors as they are passed is permissible if doing so will not delay evacuation. Do not remain in a potential blast zone simply to ventilate.

D: When HVAC intakes of a building are exposed to an outdoor natural gas leak, fresh air supply fans should be shut down to prevent drawing gas in. Similarly, HVAC systems should be shut down when the equipment or area is involved in the gas leak.

b Explanation:
NO area can be considered “too rich to burn” as these areas, at some portion of the affected space, are in the explosive range and will explode and involve the entire area if an ignition source is reached.
EP Gas 9.2.4

Question 29:
Units may be directed to work with Utility Company personnel in pulling manhole covers to create paths for natural gas to vent to open air during a major gas emergency. Which choice below reflects incorrect information regarding this tactic?

A: Sewer manhole covers may be removed by FDNY personnel with the approval of an onscene Chief Officer. The Chief Officer should ensure the area is cordoned off to identify the hazard of the open manhole.

B:Round manhole covers can be removed by two firefighters utilizing manhole hooks; Battalion vehicles carry two manhole hooks for use of this purpose. Likewise, rectangular and square electric manhole covers shall be pulled by FDNY personnel using these hooks when necessary.

C: Do not pull any electric manhole covers (or any cover if there is doubt as to its type) when there is a manhole fire in the area or smoking/arcing is observed in an electric manhole or transformer vault.

D: Round, electric manhole covers can be removed by FDNY personnel only when requested by an on-scene Utility Company worker, approved by an on-scene Chief Officer, and after the cover has been determined to be free of stray voltage by the on-scene Utility Company.

b Explanation:
Rectangular or square electric manhole covers shall NOT be pulled by FDNY personnel.
