A Parallel Stair is a staircase design featuring parallel flights of steps separated by intermediate platforms or landings. This layout is often used in commercial buildings to smartly utilize space and increase accessibility.
Benefits:
- Space Optimization: Makes perfect use of available space by allowing multiple staircases to fit within a compact area.
- Increased Accessibility: Provides convenient access to different levels with intermediate platforms that reduce the physical work required.
- Safety and Comfort: Intermediate landings increase safety by providing resting points and a place to change direction.
How does a parallel stair benefit space utilization?
It maximizes floor space by fitting multiple staircases within a compact area and provides convenient access for intermediate platforms.
OSHA Compliance for Parallel Stairs
Key points of OSHA compliance include:
- Design and construct: Design and construct parallel stairs to support the intended load and comply with OSHA standards for structural integrity and safety.
- Tread and Riser Dimensions: Adhere to specific dimensions for treads and risers to prevent trips and falls, ensuring consistent step height and depth.
- Handrails and Guardrails: Equip parallel stairs with appropriate handrails and guardrails at the correct heights to prevent falls and provide support.
- Surface and Maintenance: The stair surface should be slip-resistant and well-maintained to prevent slips and falls. Regular inspections are required to ensure continued safety.
