We have all been taught that the safe way to attack a car fire is approach at a 45 degree angle hitting the surrounding area first and than to cool down the vehicle itself before approaching and extinguishing the blaze. Right? This allows things like gas shocks, tires, shock absorbing bumpers, ect to cool off a bit before our approach to make things overall safer. Agreed???
However recently my guys have been told the new way to do an initial attack on a vehicle fire is to attach a foam tube to the nozzle and attack the vehicle with 0.3 to 0.5 class A, air aspirated foam. (not CAFS)
In my opinion, because of the limited range of a foam tube, this puts my guys way to close to a fully involved vehicle before its properly cooled down. It also takes away the ability to go to full fog for protection and back out.
What do you all think? Looking for some opinions from some senior members.
Depending on location, the team at the rear cooled the back side of the vehicle, including under the vehicle to keep the drive shaft from heating up. The team the front came in and attacked the fire. Both teams are located out of the hazard zone, where bumpers, shocks, struts, etc can launch. Start with the "reach of stream" and work your way in as the fire is knocked down.
All will depend on accessibilty. Depending on the location of the vehicle, it may not be approachable from the 45 degree angles, so the attack formations would have to be adapted accordingly, ensuring fire fighter safety. I've seen too many videos, where fire fighters were in harms way by being right in front of the vehicle, or right behind the vehicle, while it was burning.
If the fire is under the hood, and contained within, approach from the side and use a halligan or pry bar to gain/make an access hole, or if available, a piercing nozzle works well too.
Stay safe !!

Don't forget that full PPE including SCBA is a must, there are some great videos around showing magnesium reacting to water and exploding, make sure your skin is fully covered, including flash hood.

We can do it with one tank of water if required. If possible we start with a reach of stream, then move in on the vehicle as we are knocking the fire down. I say "if possible" because some locations do not permit this approach. The first line is the "attack" line, while the backup line is a "safety" line keeping things that might go boom cool ie: drive shaft if fire is impinging on it.
And I totally agree - full PPE. Hope this clarifies.
Stay safe !!
Our Standard Operating Guideline is 45 degree Class-A Compressed Air Foam (probably moving to All-Purpose foam next year) with a water backup line. This is primarily due to our experience with CAFS and the limited water supply in our area (primarily Rural, little or no Hydrant access, and the Hydrants available don't have much flow (~200GPM max).
