Fire system plumbing

[Pranav]

My system has like 6 nozzles. I was thinking of putting one in the engine bay pointed right at/above the fuel rail connections, one above each of my shoulders, and one between the legs pointed up in front of the seat.

Not sure if I want to use up all 6 nozzles. What do you guys suggest?

First of all, how big is your bottle? Mine's only a 5er, so I kept with 2 nozzles. I've got a 2 way on the trans tunnel at knee level pointing toward my torsal/crotchular area and a 3 way in the engine bay centered above/behind the intake manifold. That was the smartest thing I could come up with with such a small bottle. I think with a 10# bottle, I'd do a 3 way on me, one per bank in the engine bay, and one pointing at the fuel tankular area. Partly to keep the car from burning down, but moreso to quell the fire, wherever it's coming from, long enough for me to GTFO. 3 for the driver seems a bit much, could that possibly backfire and overwhelm you?

What does the CCR say?

It also depends a little on what kind of system it is, AFFF works different than FE36. I am about to install my AFFF system, I have 4 nozzles, I am going to 2 on each side of the engine, 1 driver crotch area, 1 fuel tank area. I read something about the fact that 95% of driver injury is from the bottom area of the car in a fire.

Somewhat on topic but I thought I'd share.

A few of us were at the WRL enduro at COTA this past weekend. The first (of many) red flags was for a serious fire which resulted in the driver being airlifted to hospital with burns to his face. Cause of said fire not established but here is what I learnt.

Helmet Visor- always have it down! This was a flash fire and the facial burns likely happened instantaneously. The driver did not have his visor down according to race control.
Car Egress- practice it! The driver did what he had practiced and got out quickly. The flames soon after were reported to be 15 feet above the car. (I need to practice this more)
Nomex Hood- wear one! I understand the driver was not and was completely within the sactioning rules.
Fire System- make sure its effective and accessable! Pranav you are on the right track. I need to reconsider if an accessable portable extinguisher is the best case when the worst case occurs
Fuel cell- install one! they wont seem that expensive when the flames are licking your ass

In this weekend's case the driver will (reportedly) recover (thank fxxk)

This is the one I have. Looks like a 15 pounder? 4.25L AFFF:

I'm not sure on the spray pattern on the nozzles.

CCR says one in cabin, one in engine bay at a minimum.

Craig, any details on what caused the fire?
