Guardrails
OSHA 1926.502 (b) 1, 3 requires that the height
of the top rails, or equivalent guardrail system
members, shall be 42 in height and capable of
withstanding, without failure, a force of at
least 200 lbs applied within 2 of the top edge
at any point.
Because of the physical leverage of the
200-pound force at the top of the guardrail, the
counter-moment force must be 42/3.75 11.2
times the force at the top of the guardrail.
Thus, the counter-moment force must be at least
11.2 x 200 2,240 lbs.
