Incident safety officer (SO2)
The safety officer has the authority to cause immediate correction of situations that create an eminent hazard to personnel
The main observable factors that influence choice of fire ground tactics:

Extension probability; protect all places fire may spread to
Type of fire; tactics should suit the situation

Benchmarks
Benchmark announced by companies for each area where a secondary search is completed.
”Secondary Search (location) - All Clear”
Also announced by the IC on status updates
The key to successful fire fighting is:
Anticipation
What the fire has already done is not as important as what it is about to do.
What size hose should the 2nd engine use for a “Back Up”line?
AND
Where should the “Back Up” be deployed?
Same size or greater size than the initial attack line.
of a different color if possible
The “back up” hose line should usually be deployed through the same entrance as the initial attack line.
Risk Management Plan
In situations where the risk to fire department members is excessive, activities shall be limited to:
Defensive operations
Assignments: 1st Arriving Engine
- Secure water supply
- Size-up (at least 3 sides)
- Position to allow access for ladder company **unless deck gun is needed due to large fire volume or immediate exposure protection
- Evaluate exposures. Exposure line or deck gun if necessary.
- Initial hose line to seat of the fire
- Officer - TIC and forcible entry tool
A source of water supply shall be secured by the 1st in Engine company unless:
The pre-plan preempts this requirement
Do not operate fire streams into smoke unless:
You encounter extreme levels of heat
You see, or suspect unseen, rollover
VEIS
If a window is already broken from the heat of the fire…
…the room is likely too hot for someone to survive in it.
Considerations in determining risk and fire ground strategy:
Fire building: type, construction (lightweight?), age, past incidents
Structural integrity: Contents or structural involvement?
Fire load: What’s burning? What’s left to burn?
Fire conditions: extent, location, time
Rescue profile: known victims, survivability profile
1st attack line placement:
Between the victims and the fire to protect the avenues of escape
Two In - Two Out
FFs will not enter an IDLH atmosphere unless:
At least 2 FFs enter together, must remain in visual and contact at all times
At least 2 FFs outside as initial backup
VEIS
Searcher Responsibilities
Advance up the ladder Breaks and clears glass Sounds floor Enters the room Closes the door Primary Search of the room
Risk Management Plan
Any risk to personal safety is unacceptable when:
There is no possibility to save lives or property
Benchmarks
Fire Out
Announced by IC during status updates
Engine companies do their work with _________ ; ladder companies do their work with __________.
Hose lines ; Tools
Benchmarks
Benchmark announced for each area where a primary search has been completed (fire area, fire floor, floor above, etc.). Repeated by IC on status updates.
“Primary Search (location) - All Clear”
Marginal Situations
