According to OSHA, guardrails must: Have a top rail height of 42 inches (±3 inches) above the walking or working surface. Withstand a 200-pound force applied outward or downward at any point along the top edge. Include midrails installed midway between the top edge and the working. The OSHA guardrail requirements 2025-26 are critical updates designed to improve worker protection in warehouses, manufacturing plants, and distribution centers. These standards specify guardrail dimensions, strength, placement, and materials to reduce workplace injuries and ensure compliance. OSHA mandates guardrails at 4 feet in general industry and 6 feet in construction to prevent fatal falls from unprotected edges. Under most building codes, a guardrail is required whenever a walking surface has an unprotected edge 30 inches or more above the floor or ground below.
