What is the maximum allowable height for vertical supports of guardrails above ground?

The maximum allowable height for vertical supports of guardrails above ground is 18 inches. This standard is often set to ensure that the guardrails provide adequate safety and stability while also being effective in preventing falls or accidents. In this context, maintaining a lower height for vertical supports helps to ensure that the guardrails are appropriately anchored and can effectively redirect or stop individuals from crossing a dangerous edge. Additionally, a height of 18 inches affords necessary visibility and accessibility for maintenance or inspections surrounding guardrail systems. By adhering to this guideline, safety regulations are upheld, making environments safer for individuals working or traversing areas where guardrails are a required safety measure.
