What is the minimum height for construction railings?

1. 6 feet

2. 8 feet

3. 10 feet

4. 12 feet

The correct answer is: 8 feet

Construction railings are designed to provide safety and prevent falls from elevated surfaces on construction sites. The minimum height requirement for these railings is crucial to ensure adequate protection for workers. In North Carolina, the minimum height for construction railings is established at 42 inches, which aligns with standard practices in construction safety and guidelines, particularly those set forth by organizations such as OSHA (Occupational Safety and Health Administration). While the option of 8 feet may seem reasonable, it actually exceeds the typical safety requirements found within construction guidelines. Construction railings at this height would not only be impractical for many applications but could also create unnecessary complexities in construction processes and standards. Ensuring that railings are set at 42 inches allows for the necessary balance between safety and functionality, making it easier for workers to maneuver and minimizing the risk of accidents while providing a protective barrier. Hence, this height standard is widely accepted across various jurisdictions, including North Carolina.
