this apartment block is old (1983) , no fire sprinkler system, and is low cost public housing like PPR. even UK also did not have mandatory fire sprinkler law for their council flats until recently.

The Longest Fire Truck Ladders in Use
If you’re wondering about the absolute longest ladders available, some specialized aerial apparatus can stretch impressively far:
Bronto Skylift F-Series: These aerial platforms can reach up to 295 feet (90 meters), but these are extremely specialized vehicles and are not common in every fire department.
Magirus M68L: Aerial ladder from Magirus can reach 223 feet (68 meters), making it one of the tallest true ladders in the world.
However, for typical urban or suburban fire departments, ladders of 100 feet are standard and sufficient for reaching 7–8 story buildings.
