What Guardrails are often used by employers to protect workers from Falls. How high must the top guardrail be above the working surface?

Employers often use guardrails as a safety measure to protect workers from falls, typically implementing systems such as standard guardrails, midrails, and toe boards. The top guardrail must be at least 42 inches above the working surface, which helps prevent accidental falls from elevated surfaces. Additionally, guardrails should be able to withstand a certain amount of force to ensure stability and effectiveness.
