SubPart Title: Fall Protection
The
standard requires guardrail systems and components to be designed
and built to meet the requirements of 1926.502(b)(3), (4), and
(5). This Appendix serves as a non-mandatory guideline to assist
employers in complying with these requirements. An employer
may use these guidelines as a starting point for designing guardrail
systems. However, the guidelines do not provide all the information
necessary to build a complete system, and the employer is still
responsible for designing and assembling these components in
such a way that the completed system will meet the requirements
of 1926.502(b)(3), (4), and (5). Components for which no specific
guidelines are given in this Appendix (e.g., joints, base connections,
components made with other materials, and components with other
dimensions) must also be designed and constructed in such a
way that the completed system meets the requirements of 1926.502.
(1)
For wood railings: Wood components shall be minimum 1500 lb-ft/in(2)
fiber (stress grade) construction grade lumber; the posts shall
be at least 2-inch by 4-inch (5 cm x 10 cm) lumber spaced not
more than 8 feet (2.4 m) apart on centers; the top rail shall
be at least 2-inch by 4-inch (5 cm x 10 cm) lumber, the intermediate
rail shall be at least 1-inch by 6-inch (2.5 cm x 15 cm) lumber.
All lumber dimensions are nominal sizes as provided by the American
Softwood Lumber Standards, dated January 1970.
(2)
For pipe railings: posts, top rails, and intermediate railings
shall be at least one and one-half inches nominal diameter (schedule
40 pipe) with posts spaced not more than 8 feet (2.4 m) apart
on centers.
(3)
For structural steel railings: posts, top rails, and intermediate
rails shall be at least 2-inch by 2-inch (5 cm x 10 cm) by 3/8-inch
(1.1 cm) angles, with posts spaced not more than 8 feet (2.4
m) apart on centers.
