scaffolding stairs
are used in lieu of ladders that are mounted in the center of the structure
gyqdlqtd. The ladder will require the worker to climb vertically to reach a
platform, and once he or she reaches that platform, the worker will need to
climb through a hole in the platform. This exposed hole can pose an extreme
danger for workers who may fall into it unexpectedly. The scaffolding stairs
eliminate this possibility by allowing access to the platform at either end,
rather than in the center. No exposed holes will exist either, and a railing can
be mounted where the stairs come up onto the platform to prevent falls or other
accidents.

The use of scaffolding stairs instead of ladders is also advantageous because
the stairs will allow a worker to carry materials from one level to another
safely and easily. Climbing a ladder often prevents a worker from carrying
materials safely, so using stairs can actually improve workflow and efficiency.
For larger loads, however, a scaffold lift will be used instead; this mechanical
device prevents the worker from having to lift heavy objects up the narrow
stairs or up the vertical ladders.
