I'm interested to see some opinions on this just to learn. I would do exactly what these guys are doing attacking the fire. Nothing looks wrong to me but then I've been wrong before.
I would be a little worried about the stability of the roof, and there does seem to be some trip hazards around. Also, since it is a working fire as iso I would be ready to have ff's going to rehab and getting vitals taken and cooling down a bit. I would be looking for any signs of abnormal stress on the firefighters and keeping an eye on the entire scene for any unforseen hazards that could possibly come up, including frantic homeowners, lookyloos,and any other of a variety of things.
I agrre that the trip hazards appear extreme and omebody should be assigned to clear this area. Roof integrety is definatly an issue and if there is no life safety issue here I would hesitate to enter I dont see a lot to be salvaged verses the risk. They als appear to be entering through a window rather than the wider door. There may be issues that are not available from just the picturees which would affect decisions being made.
As others have said, trip hazards abound and the roof looks unstable. I also do not see an established RIT team in place (assuming the IC has cleared an interior attack and those 2 firemen at the doorway are going in for interior attack)
General Answer: Structural collapse, potential occupancy issues and what caused the fire...
Not all homes come with a disclaimer that there is not a Meth Lab inside the structure...
Any house fire is always suspicious to me with the possibility that it was used to cook something, like Meth... if chemical vapors are in the air, if things are contaminated, and you are not cognizant about the possibility of a chem lab being the cause then you may find yourself getting dosed by methyl-ethyl-death or one-two-di-for-sure-in-all...
Dermal absorption from productions of combustion is a real thing. Really? You question me? Ah ha... Next time you have a working fire, and you had fun doing salvage and overhaul, tell me... how many days after the fire, when you are taking a shower does your off gassing the house fire smell?
The dermal exposure problem is well documented and well known, but a subjective thing like "smell" a day or two later might not be from combustion products on your skin.
Sometimes, it's from combustion products in your nasal passages and particularly from nasal hair coating. Dennis Smith commented on this way back in Report from Engine Company 82. My solution is a modification of his - when taking the post-fire shower, use your little fingers and a small amount of Johnson's baby shampoo and wash out your nostrils. Once that's done, just cup water in your hands and rinse out your nostrils several times. You'll be amazed at the reduction in the smoke smell.
And for anyone that's going to comment that we should never have smoke in our nostrils - that's not realistic. There are situations where SCBA isn't practical, including wildland and wildland interface fires, etc.
This thing is already through the roof so that eliminates alot of concerns as well as creating some new ones. We do not need to worry about roof ops on this one so the Truck crew is a little safer on the ground. It is already vented so backdraft and flashover are of little concern now and it makes it a little safer for the Engine crew. I would have the pump operator clear a path at the main entrance as to not impede hose advancement. I would need interior reports from the Co Officers in regards to floor stability and collpase potential. I would recommend to the IC a transitional offensive/defensive attack after a quick search was done for victims.
I'm in agreement with Shareef.
Based on what I CAN see of the house/roof, that part of the roof where the FF's are has burned through and collapsed, to the left rafters remain but the roof is burned through (this is ~6 pitch ranch roof, appears to be 2x8 dimensional lumber. For the rafters to have burned enough to collapse suggests this fire had been burning for quite some time).
Either the fire started in the part of the house where the FF are or, more likely, it started somewhere to the right and burned towards the left end of the house. In either case, based solely on what I can see, I would assume the roof is burnt off to the right, interior throughout a complete loss, no real point I can see for an "interior" attack. It's a loss, set up the lawn chairs and take lunch orders.
I only see one attack line. They might want to take a look at Firefighter Calculator on Android and iPhone to get the Critical Flow Rate right. Checkout www.a2app.com for more information on this cool new app.
Alan, I really don't believe that the firefighters in question think they have enough gmp's to knock down that fire singlehandedly (maybe they are first in, maybe there are other lines in play OUT of sight).
The discussion was about ISO, clearly your reply was self-serving in that you're trying to sell your app. (I'm not saying you app is bad or wrong, just out of place in this (or any discussion NOT about apps and water flow)). That and there are PAID sponsors here.
