I know
MikeD is out slaying dragons or something, but if he can stick his head in the thread for a minute he can probably provide a pretty good list. He's been running aviation fire services for a long, long time.
Been real busy with not alot of free time since the beginning of the year and definitely no time to hang out on the computer, but wanted to drop in on this one from someone who requested it like you are here. Yeah, I started out CFR (ARFF) a long time ago, and now run my own contract fire service as a side busness where CFR is one of our specialities, among other areas of fire/rescue/EMS.
Maybe the firewall fuel shutoff, door and emergency exit. Nothing else should really matter to them.
There's actually alot that matters to me, but it's general stuff. I don't want to know or care how to build your airplane, in terms of systems, etc. Obvious stuff like fuel shutoff, electrical shutoff, engine shutoff, etc, are important. But delving into systems themselves, for example the oxygen system, I want to know things like what type is it? Pressurized air? Liquid Oxygen (LOX)? Onboard O2 Generating System (OBOGS)? That tells me the hazard I may be dealing with in a particular instance when it comes to that kind of system. And believe me, these kinds of details are thought about, or should be. Where is the system tank or resevoir located?
And further to that, what is behind various external panels or even fuselage sections of your aircraft? Why do I care? Because if I have to cut with metal or carbide saw such as a K-12, I need to know where to in order to not hit a system, hit a high pressure line or line with flammable liquids within, or potentially hit heavy aircraft structure that could ignite. This was tragically demonstrated on 8 February 1976 in the crash of a Mercer Airlines DC-6 that crashed on a golf course while enroute from KBUR to KVNY after suffering an engine failure and physical loss of the engine and structural damage, and an unsuccessful emergency landing attempt at KBUR. The aircraft crashed onto a golf course, and there was no post-crash fire, though there was an abundance of leaking 100/130 (green) AVGAS as well as fumes from same around the cockpit area where the deceased flightcrew were entrapped. The LA County FD that was on scene, primarily consisting of structural firefighters, were making cuts on the cockpit area with a saw in order to reach the flightcrew. The area had been already foamed down, however the foam blanket surface was continually being disturbed by the firefighters walking through it, and not resurfaced or touched-up, thus allowing fumes to escape containment. While cutting, the saw team hit a portion of solid aircraft structure which generated heavy sparks that instantly ignited the fuel vapors present where the fire crew was standing. Even though the resultant fire was instantly extinguised, 10 firefighters were injured from the flash fire.
Now, as to the above, you'll notice that on many transport-category aircraft that this is already taken care of by the manufacturer in the way of external fuselage markings that are either full outlines or corner outlines that are labled "CUT HERE" or "CUTTING POINT" or something similar that visually points to the areas firefighters can safely cut into the fuselage in order to gain access. However, many lighter general aviation aircraft, including corporate jets, don't have these markings on the fuselage, which is why I like to find out from the crews or maintenance folks of these aircraft what is where, or to be able to physically look behind panels if the flightcrew doesn't happen to know.
Another item, for example, is emergency exits as well as normal exits. There are about as many different types of normal and emergency exits, as there are different types of airplanes out there. For transport category, just look at the differences as the normal exits of a 737 versus a DC-10. Or even same type aircraft, such as the overwing exits of a 737-200 versus a 737-900. Other unusual exits, such as a tailcone on the DC-9 series, or airstair on a 727 series are good to know that they exist. Thats why seeing it firsthand and demonstrated is always a good thing to experience. And it's NOT always intuitive or something that all firefighters know,
even if CFR/ARFF trained.......which training-wise, Ill address that in Amber's question.
Don't fire response teams at airports go through full ARFF training? Aren't these kinds of things covered in ARFF training?
The answer is, it depends. Depends on a good number of factors. CFR/ARFF training in and of itself is fairly general. Where you get into specifics will depend on who you are as a fire crew. Generally speaking, dedicated CFR/ARFF crews at a particular airport focus primarily on and train to, the aircraft that operate predominately from their airport. They'll seek whatever aircraft familiarization they can get from uncommon aircraft that happen to pass through, but their primary experience and training will be with what they have there. Example, an ARFF crew from a USAF fighter base may know fighter jets and dangers such as ejection seat systems and munitions very well, but may not be as familiar or current with, say, the specifics of an A320 or 767 or even a Gulfstream. Conversely, an ARFF crew at a large GA or passenger airport may not be fully familiar with the hydrozine dangers of an F-16 for example, as well as munitions or other items. Neither may or may not know helicopters well, for example. But all of these ARFF firefighters will know the basics of handling an aircraft emergency with regards to the varying types of situations that can be encountered, but not all will know the specifics of every aircraft. Thats why we have reference guides to different aircraft with regards to some of this important info.
If you happened to go down at 44N (Sky Acres, Millbrook, NY), it's likely four minutes for 911 to get out the dispatch, 4 minutes for me to get to an engine (if I'm home), and a 6 minute drive to the scene - and I'm likely alone. You're on fire for nearly fifteen minutes before the first rig can put water on you, unless you are really, REALLY fortunate. Go down at an airport with staffed fire service? Still looking at five or six minutes probably from initial impact to response time to water/foam on the fire. That's a long, long time at 1,800+ degrees.
If you go down in a field somewhere and have to rely on a cell call or hope that a nearby neighbor sees the "glow," just kiss your ass goodbye.
Very true. Remember this? :

Part 139.319. This is my first choice knowing this.
(2) The response required by paragraph (h)(1)(ii) of this section must achieve the following performance criteria:
(i) Within 3 minutes from the time of the alarm, at least one required aircraft rescue and firefighting vehicle must reach the midpoint of the farthest runway serving air carrier aircraft from its assigned post or reach any other specified point of comparable distance on the movement area that is available to air carriers, and begin application of extinguishing agent.
(ii) Within 4 minutes from the time of alarm, all other required vehicles must reach the point specified in paragraph (h)(2)(i) of this section from their assigned posts and begin application of an extinguishing agent.
Keep in mind too that one of the fastest ARFF responses to date (if not the fastest), from a complete standstill to responding and commencing an initial attack on the fire, was the response to the RTO due to an engine failure, and subsequent fire, by a British Airtours 737-200 at Manchester, England in 1985, resulting in 55 fatalities. The jet aborted its takeoff intact, but the intense fire from the ruptured fuel tank spread so rapidly, that the response within 1 minute of the arrival of the first CFR Rapid Intervention (RIV) that began fire attack, still couldn't prevent the number of fatalities, for a number of compounding reasons.
Dedicated ARFF crews obviously receive this type of training.
The VFD boys in the county where your airplane actually comes to rest likely have not.
Correct. And non-CFR/ARFF crews won't have it due to it being cost prohibitive for training and currency purposes.
Our focus is on what we "usually" get and deal with most often: extrication at car accidents, vehicle fires, single family residential structure fires and so forth..
Very true. Remember this? And this was a large city structure department too:

I'm pretty sure it's normal for fire services to document any changes to switch/valve positions that they might make to secure the crash, but a reminder to do so and not touch anything once its secured.
Done if possible and to best extent possible; but yes, not the highest priority at all.
