Caged ladders are used as a precaution for buildings that have ladders on the exterior. OSHA has a number of regulations when it comes to ladder cages. Not all ladders need cages. It all depends on the ladder’s height and the building’s height, among other factors. The cages are designed to protect the person climbing, but they are not always successful.
