The diagram illustrates that the longest aerial ladder firetruck available in North America is 137' / 41m, which should be able to reach about fourteen storeys high. A 'typical' aerial ladder is about 75' / 22m, which is about seven storeys.
- bombcar 3y agoThe ladder never goes straight up, so you need to check what its maximum “reach” is. A building that is seven stories high is going to be big enough to have multiple stairways; probably multiple elevators.
- michaelt 3y agoAn additional constraint here is that the fire trucks have to be able to navigate around the city. London has many high-rise buildings, but the many narrow roads and tight corners mean they don't operate the tallest fire trucks.
