Optimal Stair Angle: Balancing Safety, Comfort, and Space

CTA for Expert quote from Upside Innovations

Call (513) 889-2492

A critical aspect of stair design is the angle of the stair, which can significantly influence its functionality, safety, and user experience. This is especially applicable in commercial settings, where factors like accessibility and space efficiency are paramount.

The angle of a staircase, often measured in degrees from the horizontal, determines the steepness of the stairs. Common angles range from 30 to 50 degrees. However, a widely accepted standard for the most comfortable and safe stair angle is around 37 degrees.


37° is widely accepted as
the standard for safety and comfort


Why 37 Degrees?

  1. Ergonomic Efficiency: At 37 degrees, the ratio of the tread (the horizontal part where you step) to the riser (the vertical part between treads) is optimized for average human stride lengths. This angle ensures that the stairs are not too steep or too shallow, providing a natural and comfortable ascent and descent.
  2. Safety Considerations: Stairs steeper than 37 degrees can increase the risk of falls and are more challenging for people with mobility issues. On the other hand, stairs less steep than 37 degrees consume more horizontal space and may not be practical in all settings.
  3. Space Utilization: For commercial spaces where efficiency is key, a 37-degree angle offers a good balance between the vertical and horizontal space used. It allows for a comfortable rise without extending the staircase too far into the space.

Code Compliance

IBC – The International Building Code (IBC) typically requires stair slopes to not exceed a 7:11 ratio, approximately 37 degrees, with a maximum riser height of 7 inches and a minimum tread depth of 11 inches. These guidelines ensure safety by preventing stairs from being too steep and maintaining consistency in step dimensions.

ADA – Similar to IBC, the ADA requires stairs to have risers no higher than 7 inches and tread depths of at least 11 inches, ensuring a slope that typically aligns with IBC standards of around 30 to 37 degrees. Uniformity in riser heights and tread depths across all steps is crucial for safety and accessibility under ADA guidelines.

OSHAOSHA standards for fixed industrial stairs require an angle between 30 and 50 degrees to ensure safety in workplace environments. The maximum riser height is set at 9.5 inches, and the minimum tread depth should also be 9.5 inches. These guidelines are designed to prevent accidents and facilitate safe and efficient movement in industrial settings.

Conclusion

While the 37-degree angle is a general guideline, stair design can vary depending on each project’s specific needs and constraints. Upside Innovations, with its commitment to safety, efficiency, and sustainability, ensures that each staircase is optimally designed for its intended use, keeping in mind the comfort and safety of its users.

In-Plant, Modular Office Stairs

CTA for Expert quote from Upside Innovations

Call (513) 889-2492

In-plant offices are becoming more popular because the modular building industry is growing, and it is becoming easier and cheaper to access modular, in-plant offices. Stacking the modular offices on top of each other is expected to save floor space, so a set of OSHA-compliant steps is required for the upper level. What material do most people use?

It is expected to use either aluminum or steel steps because they typically last longer than wood and are quicker to assemble. People used steel more often than aluminum in the past because aluminum was more expensive. Steel and aluminum are both in the same price range, so more people are choosing aluminum over steel. Aluminum is becoming the more popular choice for three reasons:

1. Lightweight. Aluminum is typically 1/3 the weight of steel. An adjustable aluminum staircase (shown below) weighs approximately 650 lbs. including the platform. The alternative product made out of steel weighs nearly 2,000 lbs., making it a much more difficult product to handle.

2. Easily installed. Since aluminum is so much lighter than steel, assembling the aluminum staircase takes less time and effort. To install heavy, second-story steps made out of steel, people usually rent special equipment to help move the product, increasing the overall installation cost.

3. Corrosion resistant. If the indoor environment is ever exposed to water or experiences humidity, an aluminum staircase will last longer than a steel staircase because aluminum does not rust. Steel can be galvanized, which protects the material from rusting. However, the material can rust if the protective layer is scratched or damaged.

OSHA catwalk requirements

OSHA compliance stairs platforms

OSHA establishes rules and regulations to follow for equipment operators and maintenance personnel who work on catwalks, which include the minimum width dimensions, minimum load requirements, fall protection requirements, and catwalk opening requirements. Understanding these standards can help create a safe working environment.

The safety requirements for catwalks, or elevated walkways, are located in Section 1910 Subpart D of the OSHA standards. A catwalk is an elevated surface used as a pathway between buildings or along shafting. It’s also considered a type of work platform. employers need to make sure that catwalks are constantly kept safe and up to code.

OSHA Section 1910.22 dictates the primary conditions for walking-working surfaces, encompassing catwalks. To be compliant, employers must guarantee that all walking surfaces are safe from slip and fall hazards, as well as being structurally stable and sound. With that in mind, here are some key standards for workplaces with elevated working conditions:

  • Walking/working surfaces are kept in a clean, orderly, and sanitary condition. (1910.22(a)(1))
  • Free of hazards such as sharp or protruding objects, loose boards, corrosion, leaks, spills, snow, and ice. (1910.22(a)(3))
  • Walking-working surface can support the maximum intended load for that surface. (1910.22(b))
  • Employees must have safe means of access and egress to and from walking-working surfaces. (1910.22(c))
  • Walking-working surfaces are inspected regularly to ensure safe conditions (1910.22(d)(1))

Catwalk width requirements

A catwalk or runway must be at least 18 inches wide (Section 1910.28(b)(5)(ii)(A)). When a stairway accesses the catwalk, catwalk width depends on the width of the stairway and stairway landing that serves it. Under OSHA Section 1910.25(b)(4) a stairway landing must be at least the width of the stairway, which has a minimum width of 22″, so catwalks served by a stairway must have a minimum width of 22″ for OSHA compliance.

How wide does a catwalk need to be?

A catwalk or runway must be at least 18 inches wide (OSHA Section 1910.28(b)(5)(ii)(A))

Similarly, IBC-compliant stairs have a minimum width of 36″; therefore, catwalks should be minimum of 36″ wide. Some bigger catwalks might actually be classified as mezzanine structures and would, as a result, need to adhere to the IBC mezzanine egress requirements.

Catwalk load requirements

The maximum intended load is the total weight and force of all employees, equipment, vehicles, tools, materials, and other loads that an employer reasonably anticipates will be applied to a walking-working surface at any one time (section 1910.22(b) Loads)

For guardrail systems around a catwalk requires that handrails and the top rails are capable of withstanding, without failure, a force of at least 200 pounds (890 N) applied in any downward or outward direction within 2 inches (5 cm) of any point along the top edge of the rail. (section 1910.29(f)(7) Strength criteria)

Catwalk opening requirements

Catwalks may have floor holes within the walking surface or vertical openings near the edge of the walking surface. A fall protection system must protect these holes and openings to prevent employees from falling. (section 1910.28)

Hole – Opening or gap in the walking surface.

Examples include drains, large cracks, broken floorboards, chutes, and pits that are at least 2 inches.

OSHA section 1910.28(b)(7) states that where the inside bottom edge of the opening is less than 39 inches above the walking-working surface and the outside bottom edge of the opening is 4 feet or more above a lower level is protected from falling by the use of a guardrail system, safety net system, travel restraining system, or personal fall arrest system. 

Opening – Opening or gap in a wall, partition, or railing.

Examples include openings to access equipment, chute openings, and window openings that are at least 30 inches high and at least 18 inches wide.

OSHA requires that employers provide a means of fall protection around floor holes in a catwalk or other walking surfaces.

Takeaway

Estimated reading time: 9 minutes

Roof-top equipment requires ongoing maintenance to keep work environments safe. Workers accessing roof-tops to maintain equipment frequently meet accessibility challenges and obstacles such as pipes, skylights, ducts, and parapets, not to mention abundant trip and fall hazards. For rooftop accessibility and the ability to safely crossover over obstacles over 12″ height, an OSHA-compliant fixed non-penetrating rooftop stair or work platform is required.

When adding stair accessibility to roof-tops, a licensed Professional Engineer (P.E.) is required to ensure all conditions and contingencies are considered in the design, which includes not voiding any roof warranties and meeting International Building Code (IBC), OSHA, and any additional local compliance requirements. An engineer will ensure that structural considerations such as weight distribution, ongoing wear (e.g., wind displacement), and long-term maintenance are factored in. Cutting corners to get the job done should never be considered. Not only can this be costly, but certified contractors and installers are always recommended. For example, a leak in a multi-story office building due to an improperly mounted stair unit and mechanical equipment will never be worth the perceived savings of getting the job done quickly by less capable installers.

Most commercial roofs are TPO Membrane or Built-Up Roof Membrane (BUR). All roof-top stair installations should use non-penetrating mounting solutions to be effective. Roof curbs and equipment rails (see below for more info) are raised structural elements located under the roof membrane and installed when the roof is installed or redone. If your roof-top project requires these solutions, adding them can be costly and time-consuming. For lighter equipment, such as stairs, a less expensive base plate is needed to be safe and effective.

What is a TPO Membrane Roof?

TPO is a one-ply thermoplastic polyolefin membrane with a reinforcing scrim layer used on roofs to protect commercial and residential buildings from the elements. TPO Membrane Roof install

Common non-penetrating base plate installation options

If a curb isn’t possible when mounting roof-top stairs, a metal base plate solution is an easy and cost-effective alternative. In standard non-penetrating installations, the stair is anchored with countersunk bolts to a flat metal plate. The flat plate is rigid enough to distribute the weight over a wide surface area to prevent damage from point load and leaks. A thick neoprene pad is glued between the metal base plate and the roof, protecting the roof from the abrasive metal. Often the neoprene pad floats on the roof surface. Local codes may require the stair unit to be anchored to the roof.

  • Stair base plate on non-penetrating isolator pads helps mitigate leaks 
  • Flexible enough to be moved or adjusted. This includes leveling the roof-top stair.
  • Weight distribution–distribute the load (point load) over a bigger area to prevent the stair weight from creating depressions that create pooling or ponding of water. It also protects the unit from penetrating the roof surface or creating structural damage.
    • With styrofoam-insulated roofs, weight distribution is especially important.
    • When a roof heats up, it can become soft and create depression.
  • Using neoprene pads or vibration isolator pads between the flat plate and roof surface prevents abrasion from movement or wind, causing wear through the roof membrane.
  • Base plates or mounts raise stairs out of standing water after rain/snow.
  • Base plates are easier and less expensive to install.
Vibration and Movement damage from non-penetrating support

Common reasons for rooftop stair, catwalk, or crossover installations

  • To be OSHA compliant, obstacles such as pipes, ducts, or walls over 12” that workers must cross over during ongoing maintenance, require a crossover stair or a catwalk system.
  • A permanent roof-top stair or ladder is required to access the roof or crossover a parapet or wall.
  • Safe access to solar panels, roof-top units, and mechanical equipment 
  • Stair crossovers over skylights
  • Safe access to work platforms for HVAC maintenance
  • Filter changes and maintenance for air handlers and evaporator coils
  • Roof-top access for the maintenance of power vents and roof centrifugal exhaust system

Curbs or equipment rails.

What is a curb or equipment rail?

A roof-top curb is used to mount mechanical units (such as air conditioning or exhaust fans), stairs, stair crossovers, or skylights on a roof.

A curb used on commercial roofs is typically a raised structural element made from wood or concrete located under the roof membrane. Flashing and a cant strip are used to transition from the roof to the curb. Flashing is usually a thin piece of galvanized steel used where the roof plane meets a vertical surface, the curb in this instance. A cant strip creates a smooth transition from the roof deck to the curb.

Rooftop Curb or Rail – A structural element under the roof membrane the unit is mounted to.

Because the curb is raised under the roof membrane, stairs and mechanical equipment can be anchored directly to the curb. Similar to curbs, equipment rails are long structural galvanized steel units designed to mount roof-top equipment, pipe roller supports, and duct pedestals, which do not penetrate the roof and are anchored using treated wood.


Common Rooftop Stair Configurations


Rooftop Stair Compliance

In addition to OSHA and IBC compliances, occasionally, additional codes must be followed to meet local industry compliance standards. In these cases, an engineer experienced with roof-top installations must be consulted. Aside from worker safety and building codes, wind events and seismic activity often need to be factored in when designing safe and effective solutions.

OSHA

Workers maintaining roof-top equipment at heights of 6 feet or more require access to stair platforms or conventional fall protection such as guardrail systems, safety net systems, or personal fall arrest systems. §1926.501(b)(1)

OSHA requires a crossover stair for obstacles over 12″

IMC-2003 306.5 Equipment and appliances on roofs or elevated structures.

Summary of IBC codes for stairs 

  • A permanent stair access solution is required for equipment and appliances installed on a roof that exceeds 16’ in height.
  • Roof obstacles and obstructions over 30″ high require a permanent method of access, such as a crossover stair.
  • A roof with a slope of 33% slope or greater requires a permanent stair solution.
  • Permanent ladders and stairs installed to or on a roof shall comply with the following minimum design criteria:
    • The side railing shall extend above the parapet or roof edge at least 30”.
    • The space between the ladder rung should not exceed 18”.
    • Ladders must have at least 6” of toe space.
    • 18” minimum spacing between rails
    • Ladder rungs must be no less than 0.75” in diameter and capable of withstanding a load of 300 lbs.
    • Ladders over 30’ in height need a landing rate to withstand 100 lbs. per sq. ft.
    • Ladders must be corrosion-resistant.
  • Roof-top catwalks need to be as least 24” wide and require railings.

Considerations for severe winds and seismic activity

Roof-top stairs and equipment must be engineered and mounted to withstand the forces of nature, such as high winds and seismic activity. Anchoring is required to secure the curb to the roof and the roof-top air-handling equipment or stairs to the curb. To meet certain local code compliances, a spring isolation system may be required. An engineer will need to evaluate your application and recommend the appropriate solution that meets the requirements of your project’s applicable building codes. Compliance verification and calculations can be provided and are performed by a licensed professional engineer for the seismic zone in which they are to be installed.

Rise and Run for Stairs

Following building codes specific to stairs is essential in any new construction or remodeling project to ensure safety for everyone. This article outlines stair code requirements to make it easy for builders to meet relevant regulations and safety standards.

Building Codes for Stair Tread Depth

The depth of a stair tread is the horizontal distance from the vertical planes of the foremost projection to adjacent stair treads, as seen from a 90-degree angle to the leading edge of a tread. It measures the available surface area for a person’s foot to rest when ascending or descending the stairway.

Utility and Miscellaneous – General Buildings and structures of an accessory character and miscellaneous structures not classified in any specific occupancy shall be constructed, equipped, and maintained to conform to the requirements of this code commensurate with the fire and life hazard incidental to their occupancy.U

Standard Stair Tread Depth

The Industrial Building Code (IBC) and the Occupational Safety and Health Administration (OSHA) have varying tread depth specifications for various stair types. In its 2017 revision to the required walking-working surfaces, OSHA added minimum tread depths. On the other hand, IBC has long mandated a minimum tread depth.

OSHA and IBC use research on stairways with varying tread and riser dimensions to determine the minimum tread depths and maximum riser heights.

According to OSHA, a standard stair refers to any fixed or permanent stairway aside from alternating tread stairs, ship stairs, or spiral stairs. Standard stairs must, at minimum, maintain a tread depth of 9.5 inches, or 24 cm, under OSHA 1910.25(c)(3).

IBC 1011.5.2, on the other hand, stipulates that stair treads must be at least 11 inches (27.94 cm) deep, measured horizontally between the vertical planes of the foremost projection of consecutive treads and perpendicular to the leading edge of the treads.

The minimum tread depth must be 10 inches in all group R-3 occupancies, all dwelling units in R-2 occupancies, and all group U occupancies supplementary to either group R-3 occupancies or individual dwelling units in R-2 occupancies. Most multi-family dwellings intended to get occupied permanently must adhere to the standard of a minimum tread depth of 10 inches (25.4 cm).


Building Codes for Stair Riser Height

The upright (vertical) or inclined element of a stair that gets positioned at the rear of a stair tread or platform and links near the front edge of the next higher tread, platform, or landing is referred to as the stair riser height.

Standard Stair Riser Height

Depending on the type of stairway, OSHA and IBC also have varying maximum stair riser height regulations.

Standard stairs must have a maximum riser height of 9.5 inches (24 cm) following OSHA 1910.25(c)(2). IBC 1011.5.2 stipulates that the minimum and maximum stair riser heights must be 4 inches (10.16 cm) and 7 inches (17.78 cm), respectively.

In groups R-3, R-2, and U auxiliary occupancies, the maximum riser height is 7-3/4 inches.

Conclusion

The purpose of building codes for metal stairs is to ensure the safety of everyone who uses them. Any safety risk will significantly decrease if all steps and stairs have the same tread depth and riser height parameters.

For more than 13 years, Upside Innovations has been creating modular metal stairs and platforms. When it comes to design and innovation for a variety of prefabricated metal stair kits as well as custom solutions, Upside Innovations is unmatched in the industry.
