I think what foamer is saying is that, as far as the Fire & Rescue capabilities are concerned, they are ready to accept scheduled flights.
Most of the Loco's use aircraft which fall into I.C.A.O Cat7.
So should one announce flights from or to MSE, they would be able handle them without need for recruitment or too much more investment.
It takes a few years to take a guy/girl off the street and train him/her to become a fully qualified aviation firefighter.
This link provides a little more information on the RFFS.
