What is the required minimum height for guardrails on a construction site?

The required minimum height for guardrails on a construction site is 42 inches. This standard is established to ensure safety and prevent falls from elevated surfaces, which is a significant risk in construction environments. The 42-inch height is measured from the walking/working surface to the top of the guardrail system and is designed to provide adequate protection for workers who may be near edges or on platforms.

Guardrails must also be constructed to withstand a force that may be applied to them, ensuring they are secure and reliable. The height of 42 inches is recognized as effective in preventing individuals from accidentally falling over, and it serves as a critical safety feature in compliance with occupational safety standards, like those from the Occupational Safety and Health Administration (OSHA) in the United States. Maintaining this height helps promote safe working conditions and is a key part of workplace safety protocols.
