Hi George,
You need to place the pack in a manner or location so that the fire
won't spread to something else. The installation needs to assume that
the pack will burn completely. This is because the pack will likely
re-ignite because it has the internal energy to do so. That energy, once
released, has to go somewhere.
The first step is to isolate the pack from whatever connection it
may have to the grid or the dwelling. Next, you need to just pour water
on the pack to cool the remaining intact cells. Thus, you will keep
those remaining cells from contributing to the blaze. Doesn't take a
huge flow of water, but that water must remain on the pack until
everything has cooled down to more normal temperature. (Below 60
Celsius) This may take a couple of hours.
It is quite useful to have the pack on wheels or skids so that you
can drag it some distance away from everything else. If you design a
large sized pack in separate modules, and mount them separately, that
can be wise if something goes amiss.

What type of fire retardant is necessary for a battery pack fire? I have heard
of fire departments complaining that they are less than prepared to battle such
fires.
