A Mid Rail Must Be Installed When Walls Are Not at Least How Many Inches High?

• A. 18
• B. 21
• C. 24
• D. 27

Answer: (B)

Guardrails rely on more than just a top rail. When a barrier isn’t tall enough to meet the standard guard height, a mid-rail is added to provide an extra line of protection. The usual guardrail top is installed at a certain height above the working surface, and the mid-rail is placed exactly halfway between the floor and that top rail. With the top rail set at 42 inches, the mid-rail sits about 21 inches above the floor. So, when walls aren’t tall enough to reach the full protection height, the mid-rail is required, positioned halfway up to maintain fall protection.
