Make sure any prior work to the area that you are working in
has been completed. (E.g. framing, wiring, piping)
Make sure the construction of the stair cases are finished and
safe to use. If it is not complete, use ladders or staging to move
from one floor to the next in a safe manner.
Make sure the work space is clean of unused tools, equipment or
materials. If these are present make sure to clear the area you are
working in to ensure safety
