I'm a bit hesitant to run halon due to some mental delusion of it displacing oxygen. I'm worried about inhalation and the fact that it's much heavier than breathable air.




Halon and CO2 both displace air, but they're really only dangerous in closed spaces like rooms with big fixed extinguisher systems. There is some risk to inhaling the halon itself, more so from inhaling the products it releases when in a fire, but in a car situation with lots of fresh air that's not a big deal. I guess if you use it on a fire inside the car with the windows up you might have a problem, but the halon would be the least of my problems there :-0
