(b) Able to withstand at least a two hundred pound (890 n) force in any downward or outward direction.
(3) You must make sure the midrail is able to withstand at least a seventy-five pound (333 n) force in any downward or outward direction.
(4) You must make sure material encloses the area:
(a) Between the top guardrail and the toeboard on the ends and outboard side of the platform; and
