An open riser refers to a stair design where the vertical component (riser) is absent, allowing a gap between each tread. This design choice enables light to pass through and contributes to a more open and airy aesthetic in staircases.
Yes, when designed and installed correctly with proper safety measures such as guardrails, open risers can be safe.
OSHA Compliance for Open Risers
The Occupational Safety and Health Administration (OSHA) provides guidelines to ensure safety in stair designs, including open risers. Key compliance points include:
- Gap Regulations: Ensure that the gaps between treads do not exceed the maximum allowable space to prevent accidental falls or entrapment.
- Guardrails: Install secure guardrails or other safety measures to prevent falls and ensure user safety, especially in high-traffic or commercial settings.
- Load-Bearing: Verify that the stair structure can support the expected load, including considerations for both foot traffic and impact.
