Fire extinguisher

I have t3sted that brand. IMO you need the bigger of the two models to have a chance at being affective. Halon variants are okay however the deprive you from oxygen and one the cloud is dissipated your fire will be able to reignite.

That said I opted for a clean agent foam extinguisher. It won't eat the paint, foams and is a good size:

We used a lot of foam
In the steel mill and it does work great. With that said it does make a big mess and your race day would probably be over. I had Halon in my Daytona after seeing it demonstrated in the mill. That what our basements had under machinery
