There may be a temptation to build a ramp that is steeper
than 1 unit of height to 12 units of distance
in order to conserve space or reduce costs.
Before deciding to build such a ramp, remember that the steeper the ramp is,
the more dangerous it becomes to anyone using it.
Ramp Project personnel have replaced steep ramps that have caused falls resulting in
serious injuries and ramps that were so steep that the person needing it could not
use it independently.
UNLESS you have considered all the choices and your particular situation leaves you with no other choice.
