Chp 20 Flashcards
Operational strategies def
The overall plans needed to successfully mitigate and emergency Strategies depends on prefire plans, prearrival info and size up. They include: -Access to upper levels -Rescue applications -Vent -Elevated fire attack -Exposure protection -ARFF
Communications
Pre arrival: officer and driver: direction of approach, stage or commit, water supply, IC states objective
On scene: Officer size up, confirm WS plan, app turntable placement, hand signals
Tactical: Aerial deployment with hand signals, aerial operations with headsets
Access to upper levels
Maximize scrub area
Upwind
Can use as emergency egress
Can use to deliver tools to upper floors
Rescue general considerations
Mind weight limits
Upwind
Place at corners
If fire threatens, use handline to protect the aerial with a wide fog to avoid damage
For platform place with turntable directly in line with target; if using the gate approach at an angle
1-Most severely threatened
On or directly above fire floor Visible fire conditions are a good indicator Judgement made by IC, officer, or driver Real or perceived danger Panicked victims ready to jump
2-Largest group of people
Note
3-Remainder of people in the hazard area
From next most threatened on
4-People in exposed areas
Leave in place if you can
Monitor fire conditions
Raising aerial to a victim
Best position is perpendicular
If not extend till beam on bld side is above objective
Place tip above the target to avoid tip contact
Always lower to the victim to avoid jumping
Window rescue
Place first rung even with the sill
Place platform top rail even with sill, or use access gate
Roof rescue
Place tip 6’ above the roofline
Or platform bottom just above roof
Same for balconies with rails or parapets but consider use of roof ladder. Place against parapet but may collapse so consider place against aerial tip or reposition
Moving victims down a ladder
If adults, just lead
If you have to carry (last resort) keep one hand on the handrail
Crotch rocket for adults who are conscious
Side carry if not
Only do shoulder carry if you have a spotter on the ladder behind you (most dangerous)
Moving victims in a platform
Use one or two to help load conscious onto a platform, two for unconscious
Place on the floor
If on stokes, place on the rails and strap in
Lowering a stokes
If it fits, slide down the rungs. A rope at the tip is optional
If not, slide on the top rails with a rope, using poles if needed
Can be used as a highpoint as last resort. Don’t lift with the aerial.
Some have pulley’s at the tip, anchor rope to base of ladder and it extends and retracts (not for people)
Water rescue
Can help car driven into high water or person trapped in a tree. Not encouraged
Hard to position by the bank
Ladder in swift water can damage it
Ladder belt can trap and drown
Ventilation
Don’t use as battering ram
Position correctly first on unburned side not over potential vent holes
Ladder from two sides if possible
If roof isn’t good, go horizontal
Slightly above window on windward side, clipped in
Elevated master stream
For fire attack, cool embers and gasses in the thermal column, or exposures
Remember collapse
Blitz attack place in bottom of window, facing up, mind radiant heat
Never do when crews are interior
If used at ground level, line turntable up with where stream is going, aim at the ceiling
Nozzles
Fog: good for steam, might get broken up before reaching fire
SS: better for reach for interior fires
Make sure you are pumping to rated capacity
If not to mfg spec might have bad stream or damage
Foam
Generally not practical to discharge aerated foam through elevated MS
High air content makes it break up too soon
Blitz attack
Solid or straight stream
Must place close to bld and know where seat is
Can start blitz on high floor while FF make there way to it
Place at bottom of window and aim up, gives 30* angle
Only darken then shut down to minimize water damage or collapse
Defensive attack
Common, exterior attack with emphasis on exposure protection to contain fire
Solid or straight stream to reach the seat
Flow from unburned to burned to minimize pushing fire
Elevated standpipe
Good for: Avoiding well hole stretch If no standpipe Parking garage Building roof Bridges
Exposure protection
Factors affecting exposures: weather, fuel, topography, construction, spacing, intensity of fire
Remember app can become an exposure
Fog applied to thermal column may keep burning embers down
Might need to do fire attack and exposure. Position appropriately, use a fog if possible and sweep
ARFF
Escape slides are better, then portable stairs, aerial is last option, place as for window rescue to door, place as roof rescue to front of wing Position aft (rear) of entry doors If crashed in trees get victim but don't stabilize the plane If in wires, don't elevate till utilities are controlled
