There are many useful online services that focus on a specific feature of #openstreetmap, such as https://osmhydrant.org for coverage by #FireHydrants and #FireStations.

For #Vienna🇦🇹 it offers #OpenData by @datagvat to help #OSM mappers to find and map hydrants. Unfortunately, the #OSMHydrant site is apparently not maintained anymore and while it shows the latest OSM data via #OverpassTurbo, it ignores latest #OpenData updates. Please do not blindly rely on it.
