Vertical leap is prized in the Olympic high jump and when dunking a basketball, but the athletes need a running start to reach those heights.

Maintenance and production staff in modern industrial plants also must reach elevated work areas; however, these facilities do not have the luxury of wide open spaces for them to get off the mark. The pressure for manufacturing floor optimization leads to extensive—and creative—use of factory and warehouse vertical space.

Building upward with mezzanines and multi-level platforms enables companies to make cogent use of their operations. It must be done with safety and efficiency in mind. Industrial stairways, mezzanine railing systems, and safety gates enable space efficiency while ensuring compliance and safety.

The proper steps for safeguarding stairways.

When a facility adds a second level, safe, code-compliant access must follow. Industrial stairways and ladder systems are a staple of daily workflows and a critical safety component. Engineered systems constructed from heavy-gauge steel handle industrial traffic and provide secure vertical access. They turn unused airspace into functional real estate.

Highlights of OSHA stairway requirements include:

OSHA 1910.25(b)(3) and (b)(4) for general industry states that stairways must have uniform riser height and tread depth with landings at least the width of the stairs.

OSHA 1910.25(b)(6) says that each stair must support at least five times the normal anticipated live load, but never less than a concentrated load of 1,000 pounds applied at any point.

OSHA 1926.1052(c)(3)(i) and (c)(4) require handrail heights of at least 36 inches and midrails halfway between the top rail and steps.

Securing elevated work areas and mezzanines.

Elevated work areas and mezzanines are among the most effective ways to maximize vertical space in manufacturing. However, they introduce significant fall hazards, making comprehensive mezzanine safety protocols essential.

For example, OSHA standards for guardrails on walking-working surfaces require a top rail height of 42 inches (+/- 3 inches) and that the top rail be able to withstand a force of 200 pounds (890 N) applied in a downward or outward direction within 2 inches of the top edge, at any point along the top rail (OSHA 1910.29(b)(1) and (3)).

Industrial mezzanine systems increase storage or work access space significantly and can be installed within an existing facility. Featuring a modular design, they can be customized to fit specific floor space and storage requirements. They can also be reconfigured if the needs or layout of the facility change.

To ensure safety:

• Platforms must be engineered to handle the expected load and storage weight.
• Perimeter guardrails with appropriate handrails and toe boards are critical along all exposed edges.
• Access points should be secured with self-closing safety gates.

Spring-loaded swing gates close automatically when a worker passes through, ensuring that openings at the top of stairways or ladders are never accidentally left unguarded. Available in both single- and double-width models, they can be cut to size and easily integrate with guardrail systems, stairways, and a variety of round and square surfaces.

Safety for real-world workflows.

Optimizing vertical space intelligently requires integrating all safety features into daily workflows. Efficient use of vertical space can dramatically improve capacity and operations. By combining well-designed, OSHA-compliant industrial stairways with robust industrial mezzanine systems and critical fall protection—including guardrails and safety gates—facilities can expand upwards safely, while bolstering capacity.
