The CAA wrote sometime ago to Aerodrome Licensees laying out the contingency requirements in event of a National/Local strike. (Letter in office) I am not AFS personnel however.
The Airport Fire service is seen as the initial response in a major incident - at Full Emergency status or above, most airports will have support from their local authority services. An airport service will discharge its entire "on board" foam/water supply in a very short time and if the fire is not extinguished / damped down to enable rescue, support for additional water supplies has to come from an external source...........or from an on airfield supply very rapidly.
Whether or not each airfield can attain the required standards remains to be seen. I will be landing in the U.K. in an aircraft requiring CAT 8 cover on one of the planned strike days
