Many larger fire departments have successfully utilized an outside
vent position for years, however for many smaller suburban departments the use of this
valuable position has never been explored.

Opinion: Ventilation has never been more important and needs to be our #1 tactical priority (make the building behave!*)

“The immediate assignment of one or more members to vent the fire-area windows from the outside is an extremely important assignment to be made. After the placement of the initial attack hose line and designation of an interior search team, quite possibly the next most important position to be covered is the OV position.”John Norman – FDNY Retired

Key Fireground ImprovementsLewisville & The Colony, Texas
• The addition of an outside vent person.• The addition of a field incident technician.• Pre assigned fireground roles and
responsibilities.• Emphasis on the basics.• Immediate feedback.• Reality training.
![Page 6: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/6.jpg)
The Role of the OV
• Immediate exterior survey.
• Locating victims.• Locating the seat of the
fire.• Creating firefighter escape
routes.• Assisting with horizontal
ventilation.• Addressing utilities.

Prerequisites for an OV
• Fire experience.• Ability to read smoke.• Understands fire behavior.• Knowledge of building construction.• Understanding of ventilation principles and
practices.• HIGHLY DISCIPLINED
![Page 8: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/8.jpg)
You don’t want the guy with the melted helmet or the No Fear stickers on his helmet as your OV.
![Page 9: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/9.jpg)
The OV position IS NOT a free lance position.
The OV is an assignment authorized by the IC
with specific tactical objectives, operating guidelines and strict
communication and accountability standards.

Assigned immediately on all structure fire calls
![Page 12: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/12.jpg)
If staffing is limited, the OV may be re assigned once the OV’s tactical objectives have been completed, hose lines have reached the seat of the fire, the extent of the fire has been determined and an all-clear transmitted.
![Page 13: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/13.jpg)
Priority should be given to maintaining the OV position, especially if no other officer has been assigned to Division C.

In the event of a MAYDAY, the IC must give serious consideration to re activating the OV position.

The OV Size Up
• Victims• Egress points• Fire/smoke conditions/extension• Ventilation needs• Utilities• Any other hazards

Reading Smoke Short Cuts (HINTS ONLY)
• Black/Thick/Fast = heat and explosive• Black/Thin/Fast = flame near• White w/Speed = hot – but fire is distant• Uniform speed/color (steady flow & light
color)from many places = deep seated fire • Brown = unfinished wood being heated• Turbulent = FlashoverCourtesy of Dave Dodson: firegihtersclosecalls.com

Ladder Needs
• Ground– Second story (rescue, FF egress)– Roof (vent team 2nd means of egress)
![Page 24: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/24.jpg)
Communications
The OV MUST have a radio and be able to communicate with:• IC• Eng. Officer• Truck Officer• RIT• Divisions
![Page 25: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/25.jpg)
Division C - OV Duties
• Doors and windows• Controlling the door• Throwing ladders
![Page 26: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/26.jpg)
Breaking Windows Review
![Page 27: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/27.jpg)
Assess the value of braking windows for: Life safety
Fire control
![Page 28: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/28.jpg)
Breaking Windows
How will breaking windows impact:• Victims• Search crew• Fire attack crew• Fire/ smoke conditions• Exposures
![Page 29: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/29.jpg)
Fire travels the path of least resistance, up, across, down to oxygen supply.
Breaking a window will intensify and draw the fire.
![Page 30: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/30.jpg)
Breaking Windows
• Pay very close attention to wind conditions.• Coordinate with search, hose and other vent
crews.• Take all of broken windows.• Take fire room windows.• Take windows opposite hoselines, never
behind.• Take windows when you hear fire streams.
![Page 31: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/31.jpg)
USE EXTREME CAUTION WHENventing windows remote from the fire room.
![Page 32: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/32.jpg)
DO NOT TAKE WINDOWSbetween the fire and search/attack crew’s point of entry.
![Page 33: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/33.jpg)
DO NOT TAKE WINDOWS UNTIL READYif fire is in smoldering stage. The introduction of air may cause a backdraft or rapid fire extension.
![Page 34: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/34.jpg)
Incidents to Review
• Charleston – Breaking windows and fire behavior
• Baytown – Broken windows and wind• Dallas Fire Rescue – Firefighter rescue• Lake Cities Training – Firefighter rescue
![Page 35: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/35.jpg)
Focus on taking windows in the fire room and the area around not involving search.
Be aware of the status of water, attack and search crews.
![Page 36: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/36.jpg)
Rescue and the OV Review
• Check inside doors and windows with senses and tools (TIC, hook, irons, personal rope)
• Use tools to extend reach, maintain contact with door/window
• Communicate findings with IC ASAP• Perform VES only if trained and after notifying
IC
![Page 37: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/37.jpg)
Vent Enter Search
• Is the OV allowed to perform VES?• Are there SOGs and training to support VES?• Must be conducted by a smart, experienced
firefighter ONLY.

VES Review
• Must apply risk management plan• Must communicate with IC• Must have SCBA / radio / tools• Must control the room– Close door– Navigate quickly– Be able to exit quickly
• MUST STAY IN ROOM OF ENTRY…NO EXCEPTIONS
![Page 40: THE OUTSIDE VENT POSITION for Suburban Fire Departments](https://reader035.vdocuments.us/reader035/viewer/2022081514/5681690d550346895de02380/html5/thumbnails/40.jpg)
The OVM and the Mayday
• Can perform “hot laps”.• Continually monitor conditions. • Listen / look for evidence of the lost
firefighter(s).• Tract progress of interior crews from an
exterior position.• Vent / open-up as needed.• Assist with removal from exterior position.
