To erect a ladder, place its foot against a fixed
object such as a wall and raise the other end by
progressing hand over hand, from rung to rung
until upright.  Make sure the ladder is erected the right way
up. If it is wooden ensure the tie rods are
underneath the rungs, if it is aluminium check
the rung profile is the right way round
