What is the maximum height allowed for a scaffold guardrail?

1. 40 inches

2. 45 inches

3. 50 inches

4. 55 inches

The correct answer is: 45 inches

The maximum height allowed for a scaffold guardrail is 45 inches. This regulation is in place to ensure safety for workers at elevated heights. Guardrails are critical for preventing falls and protecting individuals who are working on scaffolds, which can be particularly hazardous environments. A guardrail that is set at 45 inches provides an adequate barrier while still allowing workers to operate effectively without impeding their ability to perform their tasks. This height is designed to be effective for a majority of workers and to accommodate typical work practices. The other heights provided do not meet safety standards as prescribed by relevant safety organizations. Standards are established based on extensive research into safety measures and practical requirements, illustrating that 45 inches is an effective compromise between accessibility and security against falls.
