What does OSHA recommend regarding the number of landings in long flights of stairs?

OSHA recommends avoiding long flights of stairs primarily because lengthy stairways can pose increased risks for users, such as fatigue and potential accidents, particularly for those who may have mobility issues or are carrying heavy loads. Long flights can lead to a higher likelihood of falls or missteps, which are some of the most common accidents in workplace environments. By minimizing the length of stair flights, safer conditions can be created, allowing for more manageable access between different levels of a building. This guidance aligns with promoting worker safety and reducing the potential for injuries associated with stair use.
