Ten Minutes in the Street: "Here's Lookin' at You"
In this our latest street view, let’s take a look at what appears to be a fairly typical residential occupancy, located in a typical residential area. The street assignment is somewhat simple, or so it may seem;
• Develop a LIST of size-up considerations,
• Questions that come to mind in viewing the structure,
• Observations that raise issues with your strategic or tactical IAP,
• Safety Concerns,
• Operations Concerns,
• What IS Obvious?, What is NOT?
• What is it about this Residential Occupancy that you’re concerned about?
Develop your running list, as you look over the occupancy and think about the dynamic risk assessment and size that you would have to perform upon your arrival at this address for a report of a structure fire.
There’s a lot to identify, postulate, discuss and think about. Let's see what we share in common, or what different perspectives we bring to the table...
So, here’s lookin’ at you kid, see what your eye, experience and gut is telling you…..

One problem I see is getting apparatus up the driveway. I don't know how far away this house is from the road. Another potential problem is that steep slope on the D side of the house. During heavy involvment, I would be afraid of the house shifting and eventually falling in that direction. Vertical ventillation is going to be pretty much impossible unless done from a truck. What we can't see is what's on the C side. We can't tell if there is a basement. There are no cars in the driveway but you can tell the house is inhabited. This house would down right suck after an ice storm went through.

Big House , Big volume of water, Long skinny driveway, need to split lay in Truck would have to go in Pole barn side of house to catch two side of house and Exposer Out Bldg.. Big search area..Truss const. Drop off elevation to rear may be laddering problem.. New Const. Tyvek wrapped well Insulated, and tripple pain glass.. No cars..Maybe in Garage..Big peak hard with roof ladders use possibly 2 together?? Chimney's side C & D .. Gas Line up center of yard and driveway Large overhang on Front door possible collapse and trap..Maybe Apt. above garage.. Probably walk out basement rear looking at elev...Many more I'm sure.....Thanks Chris

Very insightful comments so far, thanks for taking the time to rely....Now how about manpower needs and companies...what do you think the needs are and fire flow requirements for 25% fire involvment, lower level house plan areas...

I agree 5000+ sq/ft home so second alarm right off the bat with this one.
Hydranted- as mentioned before dual lay to attack Engine & Truck
Non-Hydrant area- Tanker Shuttle so an additional Engine on the assignment at a minimum. Fill Site Engine, Dump Site Engine & Attack Engine with LDH laid from Dump site in the street to Attack Engine. In this case a 3rd alarm for Tankers could be very possible.
Manpower
IC/Staff- Minimum 4 Officers IC, Safety, Ops, Water Supply at a minimum
RIT- Size and complexity of this structure need a minimum of one 4 person RIT team.
SAR-Really need 3-4 teams to perform an 'adequate' search.
FA- 3 teams
D/O- 3 Attack Engine, Truck & either Dump site Engine OR Squad
So a minimum of 30 firefighters ONSCENE. I stress onscene because in this tally I'm not accounting for Tanker D/O's and Fill Site personnel.
Figure 5000sq/ft structure so 25% involvement 400+gpm. This would definately be a situation where either A) the deuce and half comes off the Engine right away OR B) Two 13/4 attack lines come off simutaneously to initiate suppression.
Note the 21/2 doesn't give you the desired gpm so a 13/4 still needs to come off quickly.

I would have to agree with Jay. Big fire = Big water. A definate water supply has to be a high priority when setting up for operations on this one. For 25% involvment, you will have to attack fast to keep this one from taking the house.

I don't know about flow requirements, lots of water is all that i can tell you(i am only an Explorer, so all i can say is large hand lines, 1&3/4" and 2&1/2").
But what i can tell you is if LAFD responded to this house we would have 3 Taskforces, 1 Lightforce, 3 Single Engine Co's, 5 Rescues (3 ALS 2 BLS), EMS capt., Battalion, and Division.
Taskforce = 1 Truck, 1 Engine, 1 200-series engine (aka an engine used as a pump)
Lightforce = truck and 200 series engine
so for this call we would have 4 trucks, 6 engines, 4 pumps, 5 Rescues/Ambulances and the command stuff
I have another question for y'all!
You are the Engineer on the first arriving engine co. with addition resources 4+ minutes out!
You see medium smoke from the 'c' side of the building. You have hooked up to a hydrant to the right of the house.
Where would you spot your engine??

A couple of point on this one - the slope on Side C says "Walk-out basement" to me.
Without re-hashing the excellent points that have already made, I have a couple of other observations.
Walk-out basements have contributed to several high-profile LODDS, especially when no one did a 360 prior to starting an interior attack. Walk-out basements that aren't noticed early can lead to putting firefighters above unrecognized basement fires. It can also cause confusion about what level is Division 1, Division 2, etc.
Multiple modified hip roof construction is bad news for any attic fire or fire inside the soffits. A small fire can spread virtually anywhere around the structure. It will take lots of ladders, lots of firefighters, and lots of work to dig it out. A bigger attic fire can spread laterally around the living quarters, then break out into the living quarters in several places almost simultaneously.
