This shot of the PS rear nicely illustrates the layout of the medical compartment, pump control panel, first aid hose reel, dual one man hose carts and the ladders, not forgetting the mandatory hook ladder.
These engines won't be replaced, as pure ambulance and EMS ambulances are taking over. Nowadays light pumpers are replacing the PS

Yes it seems the demand for EMS response was taking these PS combination units away from their base stations too often for them to be adequately available for response to fire calls, so the idea of having the same vehicles and crew members deal with fire and EMS calls was becoming untenable. Here in the US many full time city fire departments provide EMS response, but very few cross-crew for the same reason. While fire trucks usually average around five runs a day, ambulances often average eight or more.
In rural France, cross crewing is commonplace, because call volumes are so much lower, but the Departmental services all operate separate fire trucks and dedicated ambulances.
