THE OUTSIDE VENT POSITION

for Suburban Fire Departments

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!*)

*Tom Brennan – we’ll never forget you!

“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.

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

You don’t want the guy with the melted helmet or the No Fear stickers on his helmet as your OV.

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.

Assigning/Terminating/Restoring the OV

Assigned immediately on all structure fire calls

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.

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.

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

Important Clues

• Toys • Handicap ramps• Security doors and windows• Pool• Dogs• Multiple electric meters• Multiple mail boxes

Tool Selection

Commercial• Irons• All purpose hook• Saw• Radio• Thermal imager

Ladder Needs

• Ground– Second story (rescue, FF egress)– Roof (vent team 2nd means of egress)

Communications

The OV MUST have a radio and be able to communicate with:• IC• Eng. Officer• Truck Officer• RIT• Divisions

Division C - OV Duties

• Doors and windows• Controlling the door• Throwing ladders

Breaking Windows Review

Assess the value of braking windows for: Life safety

Fire control

Breaking Windows

How will breaking windows impact:• Victims• Search crew• Fire attack crew• Fire/ smoke conditions• Exposures

Fire travels the path of least resistance, up, across, down to oxygen supply.

Breaking a window will intensify and draw the fire.

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.

USE EXTREME CAUTION WHENventing windows remote from the fire room.

DO NOT TAKE WINDOWSbetween the fire and search/attack crew’s point of entry.

DO NOT TAKE WINDOWS UNTIL READYif fire is in smoldering stage. The introduction of air may cause a backdraft or rapid fire extension.

Incidents to Review

• Charleston – Breaking windows and fire behavior

• Baytown – Broken windows and wind• Dallas Fire Rescue – Firefighter rescue• Lake Cities Training – Firefighter rescue

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.

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

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

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.
