A guardrail, or guard rail, is a stationary, fixed fall protection system designed to prevent workers from stepping over the edge of a walking-working surface. OSHA 1910.29(b) is the portion of the regulations that contains system requirements that employers must follow to ensure guardrail systems will protect workers from falling to lower levels.
There are three main parts of a guardrail: The top rails, the midrails, and the vertical posts. Each part of the guardrail must comply with OSHA’s rules, including material type, size, height, and location. We explain each of these below.
Diversified Fall Protection provides turnkey guardrail systems that comply with all of the following OSHA requirements for guard rail.
According to OSHA, top rails (or equivalent guardrail system members) must be 42 inches (107 cm), plus or minus 3 inches (8 cm), above the walking-working surface. The top edge height may exceed 45 inches (114 cm), as long as the guardrail system meets all other criteria.
Guardrail is required for any platform 4 feet or higher above a lower floor or the ground. Guardrails are required have vertical heights of 42 inches from the upper surface of the top rail to floor, platform, runway, or ramp level.
If there is not a wall or parapet at least 21 inches (53 cm) high, then midrails must be installed halfway between the top edge of the guardrail and the walking-working surface. Screens, mesh, intermediate vertical members, solid panels, or other equivalents can be considered “midrails” for this purpose.
If screens and mesh are used, they must extend from the walking-working surface to the top rail and along the entire opening between top rail supports.
Intermediate vertical members (such as balusters) must be installed no more than 19 inches (48 cm) apart. Other equivalent intermediate members (such as additional midrails and architectural panels) should be installed so that the openings are not more than 19 inches (48 cm) wide.
OSHA requires guardrail be strong enough to withstand force both outward and downward along the top rail and at the midrail section.
Guardrail systems need to be capable of withstanding a force of at least 200 pounds (890 N) at any point along the top rail. This force is applied in a downward or outward direction within 2 inches (5 cm) of the top edge. When tested in a downward direction, the top rail of the guardrail system must remain at least 39 inches (99 cm) above the walking-working surface.
Midrails, screens, mesh, solid panels, and other equivalent intermediate members must be capable of withstanding, without failure, a force of at least 150 pounds (667 N) applied in any downward or outward direction at any point along the intermediate member.
Guardrail systems need to be smooth-surfaced. This is to protect employees from injury, such as punctures or lacerations, and to prevent catching or snagging of clothing. Our railings have a powder-coated finish to meet this requirement.
OSHA also requires that the ends of top rails and midrails do not overhang the terminal posts, which are the posts at each end. The only exception is if the overhang does not pose a projection hazard.
Similarly, steel and plastic banding are not permitted to be used for top rails or midrails, and guard rails must be at least 0.25-inches (0.6 cm) in diameter or in thickness. These requirements also protect workers from injury caused by too much force applied at these points.
OSHA says that when guardrail systems are used at hoist areas, there needs to be a removable guardrail section placed across the access opening when employees are not performing hoisting operations. This section must have a top rail and midrail. You may use chains or gates instead of a removable guardrail section if you show they provide the same level of protection as guard rails.
Guardrail systems used around holes must be installed on all unprotected sides or edges of the hole. If materials will be passed through the hole, no more than two sides of the guardrail system can be removed at a time. When materials are not being passed through the hole, the hole must be guarded by a guardrail system along all unprotected sides or edges or closed over with a cover.
When used around holes that serve as points of access (such as ladderways), the guardrail system opening needs to have a self-closing gate that slides or swings away from the hole. The gate must have a top rail and midrail (or equivalent intermediate member) that meets the requirements for guardrail above. The other option is to offset it to prevent an employee from walking or falling into the hole.
For ramps and runways, guard rail must be installed along each unprotected side or edge. You can use Manila or synthetic rope for top rails or midrails if it is inspected as necessary to ensure that the rope continues to meet OSHA strength requirements described above (the 200-pound and 150-pound tests).
Diversified Fall Protection provides a range of OSHA-compliant guard rail and safety railing to protect your team, including LORGUARD.
The Occupational Safety and Health Administration (OSHA) provided new fall protection standards back in Fall of 2016. These updates became effective in January 2017 and many of them align general industry regulations for OSHA guardrail height, ladders, and stairways with construction standards.
Organizations continue to work toward understanding and implementing the required changes and complying with OSHA regulations. Although the updated standards have been in place, many employers remain confused or have questions about the changes required of their fall protection and guard rail system.
Areas of confusion often arise with fall protection railing requirements, OSHA guardrail height, handrail requirements, and safety railings / temporary guardrails. This is especially true when differences arise in Cal-OSHA guardrail regulations.

There are many places in a facility or on a rooftop that pose a hazard for workplace injuries and fatalities. Many rooftops include elevated pipes, ducts, HVAC equipment. Technicians need to access these structures from an elevated position and may need safety railings. A roof handrail can also provide a physical barrier and help prevent falls from the edge, and is an important measure to be taken along with standard roof hatch guardrails.
A safety handrail helps to provide stability for a handhold whether on a walkway, steps, or platform. Fall protection guardrails are a system of railings to prevent workers from falling off a landing, platform, or walkway.
Common applications include standing seam or metal roof fall protection installations and the popular Accufit system for flat roof railings. Including guardrails and safety rail systems is an important consideration in fall prevention systems. Further, complying with OSHA’s safety railing and requirements can reduce falls and citations.
Are you curious about OSHA handrail requirements or what OSHA railing height is appropriate for your facility? First of all, here are some applicable requirements for guardrails and safety railings included in OSHA’s Walking-Working Surfaces standard for general industry to help prevent fall hazard, 29 CFR 1910.29:
OSHA 1910.29(b)(1):
To meet OSHA’s guardrail height requirements, the top rail needs to be 42 inches plus or minus 3 inches above the walking-working surface. This is the first OSHA requirement to be aware of. We will now cover some additional areas.
OSHA 1910.29(b)(2)(i-iv):
If the vertical opening in the rail is more than 19 inches, then there must be a mid rail / intermediate rail. Install the mid rail halfway between the top rail and the walking surface. The distance between intermediate vertical members (such as balusters) is no more than 19 inches. Openings are no more than 19 inches wide for other intermediate members (such as additional mid rails and architectural panels). (This is where the measurement of an equivalent intermediate member comes into play.)
OSHA 1910.29(b)(3),(5):
This fall protection requirement deals with the strength of the railing. They are to withstand a force of at least 200 pounds applied in a downward or outward direction within 2 inches of the top edge at any point along the top rail. Mid rails (and each intermediate member) are to withstand a force of at least 150 pounds applied in any downward or outward direction.
Also, OSHA standard 29 CFR 1910.28 includes information that employers need to ensure that a fall protection plan is incorporated when employees are exposed to a fall of 4 feet or more to a lower level. Keep in mind that even temporary work situations such as scaffolds should be addressed. (Solutions such as a personal fall arrest system can aid these arrangements.)
As you can see, there are various OSHA provisions detailing when guardrails and railings should be used and how they should be constructed. And yet there are more provisions depending upon the application. It gets confusing for many people charged with locating and installing the right solution.
OSHA 29 CFR 1910.23 includes requirements for ladders, where OSHA defines handrail requirements on platforms and how high safety railings must be. Handrails are required when there is a top step height of 4 feet or more and a railing needs to be 29.5 inches for stands with a top height of 4 feet or more, 36 inches for stands with a top step of 10 feet or more.
There’s also confusion about the need for gates around ladders. There’s a misconception that a safety chain can be used to protect a ladder entrance. According to OSHA, a gate is required at the top of all ladders. In fact, OSHA requires a guardrail system and toe boards on all exposed sides (except at the entrance) of a ladder way floor hole or ladder way platform hole (29 CFR 1910.28(b)(3)(iv)).
To meet OSHA requirements in the construction industry, if workers are six feet or more above a lower level, there must be protection from falling by the use of guard rail systems, safety net systems, or personal fall arrest systems (29 CFR 1926.501(b)(1)).
OSHA guardrail requirements also include that safety railing systems be required even when occasional or temporary work is performed on the roof, whether for repair or for maintenance. In addition, a roof handrail must be able to withstand 200 pounds of force without falling.
Safety railings can also be used commercially to protect workers and pedestrians from falls off steps, walkways, platforms or other raised areas. These guard rail systems provide safety for various applications including protection over a stair rail system, culverts, ramps, service platforms, loading bays, mezzanines, and pedestrian pathways.
In addition to creating a barrier to prevent falls off a raised area, they also provide a handhold when ascending or descending. And in situations where a more temporary or less penetrating solution is required, parapet railings (wall clamps) are worth exploring.
Bottom line: railings provide a needed barrier and help protect people from falls. Yes, it may seem like there are so many rules (OSHA and more) to understand and follow, but the whole point of these rules is workplace safety. It is important to keep workers safe, to prevent falls, and maintain a culture of safety. The number of workplace fatal falls is growing. In fact, in 2017 the Bureau of Labor Statistics reported that fatal falls reached their highest levels, 887 worker deaths. This is one reason why installing both passive and active fall protection solutions is so critical.
