Understanding Building Codes: Why Are Open Risers Forbidden in Staircases?

Explanation:

Open Risers Safety Risk: Open risers are the spaces between the treads of a staircase. Building codes in most areas forbid open risers because they pose a safety risk. Without a solid riser to prevent slipping through or getting a foot stuck, open risers can cause accidents. For example, a small child could fall through the gap or someone's foot could slip between the treads.

Closed Risers for Support: By requiring closed risers, building codes ensure that staircases are safe for everyone to use. The closed risers provide support and prevent potential hazards that could occur with open risers.

Regulating Gap Size: Additionally, building codes often specify the maximum gap size between treads to further enhance safety. This regulation helps to prevent tripping hazards and ensures that staircases are built to a safe standard for users.
