What is the minimum height for horizontal guard railing above the ground?

24 inches
30 inches
36 inches
48 inches

The correct answer is: 30 inches

The minimum height for horizontal guard railing above the ground is established to ensure safety and prevent falls from elevated surfaces. A height of 30 inches has been determined as adequate to provide a protective barrier while allowing for ease of use and visibility. This height is generally recognized in both safety regulations and industry standards, effectively safeguarding individuals working or walking near elevated edges without being impractical for access or visibility. While higher guard rails may offer additional protection, the 30-inch height meets the necessary safety standards for most circumstances, making it the appropriate choice for this guideline.
