In order to comply with OSHA standards, handrails manufactured from metal pipes should have a minimum cross-sectional diameter of 1.5 inches, while hardwood handrails should have a cross-sectional diameter of at least 2 inches. OSHA regulations also require handrail installations to have a multidirectional load-bearing capacity of at least 200 pounds.
A handrail conforming to OSHA standards should have a lengthwise section attached directly to a partition or wall, explains the U.S. Department of Labor.

In addition, OSHA regulations prohibit handrail installations that create projection hazards, and the standards require a minimum 3-inch clearance around handrails.
