I don't know where you live, but if SC's closer the South Carolina Fire Academy offers a class called Rescuing the Rescuer, I've taken it, it's very good, and the basic stuff can be easily remembered and taught in house by a training officer. Rope, another scba w/ mask (can make a bag for it if your dept doesn't want to buy one), and cutting instruments are main essentials and will be able to handle many problems. The handcuff knot is a very valuable tool, you can bring ff's up and down floors with it, see if someone knows it at your fd.
I'd say the main theme would be either think or communication
