What is the minimum horizontal load that intermediate rails or balusters should be able to withstand on an area equal to one square foot?

The minimum horizontal load that intermediate rails or balusters should be able to withstand is specified to be 50 pounds per square foot. This requirement ensures that the components of a railing system provide adequate safety and structural integrity, particularly in areas where there may be a risk of someone applying pressure against them, such as when leaning on them or during a fall.

This standard is part of building codes and safety regulations intended to prevent accidents and ensure that railings can support expected loads in everyday use. If the intermediate rails or balusters are not capable of handling this load, they might fail under stress, leading to catastrophic consequences. Understanding and applying this requirement is crucial for both construction and home inspections to ensure compliance with safety standards.
