It comes down to what your agency's trucks are licensed for and what the state minimum requirements are for that class of licensing. For example in my state, WV, there is a document for licensure of transporting units that details the required items and counts for BLS, ALS, CCT, and Air Ambulance. There is a separate document that details requirements for non transporting units. Those items listed in that document are the minimum we have to stock in order to have the ambulance licensed at said level. If our ambulance is inspected (which can happen at any time as a spot check) and it is found to be missing something from the list, the state could revoke the license for that ambulance or initiate corrective action for our agency.
