Need someone's help if possible.

We recently purchased a "new to us" rescue truck and a discussion is raging over the transfer of our cascade system to the new truck.

The truck will be used as our R.I.T. response unit as well as vehicle rescues and structure fires.

My question is this: Is there anything in the NFPA guidelines for RIT that states we should bring our own air? I don't feel we can always rely on having a cascade at any scene we might go to so I think we should install it.

Any help is appreciated. Thanx.
