What is the maximum spacing allowed between balusters to ensure safety?

The maximum spacing allowed between balusters to ensure safety is aligned with building codes to prevent small children from passing through or getting stuck. The correct spacing of 100 mm (4 inches) is established to provide adequate safety, as it is small enough to prevent a child's head from fitting through, thus decreasing the risk of accidents.

The intent behind setting this specific distance is to balance the structural integrity of the railing with safety considerations. Wider spacings could allow for a child's body to slip through, posing serious safety hazards. Building codes are designed to create environments that protect occupants, especially in residential settings where children may be present.

In contrast, smaller spacings would be more restrictive and unnecessary for safety, given that a 100 mm maximum still maintains structural strength without compromising the function and aesthetic of the railing. Therefore, understanding and adhering to this standard is crucial in carpentry and construction to ensure safety in building practices.
