What is the minimum height requirement for a scaffold guardrail?

1. 36 inches

2. 42 inches

3. 48 inches

4. 54 inches

The correct answer is: 42 inches

The minimum height requirement for a scaffold guardrail is established at 42 inches. This standard is crucial for ensuring the safety of workers who are operating at elevated heights. The guardrail system serves as a protective barrier to prevent falls, which can lead to severe injuries or fatalities. The height of 42 inches is determined to be effective in providing necessary protection while still being within a practical range for workers to navigate safely on scaffolding structures. The design of guardrails not only aims to meet these height specifications but also to minimize gaps that could allow tools or materials to fall off the scaffolding, further enhancing workplace safety. Meeting the 42-inch requirement thus reflects compliance with industry standards and regulations aimed at keeping workers safe from falls.
