Info needed.

Currently my department utilizes Survive Air packs with the rapid refill system to refill cylinders on the fire ground when there is a possibility of radioactive contamination. This is so the cylinder does not have to be removed. I was wondering if anyone else does this, and if so, can I get a copy of the proceedure used. I'm also looking for a way to carry up to nine cylinders, or a bank of cylinders on a pumper with minimum space. If anyone can help, thanks in advance.
