Stephenson, [11] The Stairway Manufacturers' Association, (877) 500-5759, provides a pictorial guide to the stair and railing portion of the International Residential Code. even where disabled individuals are not the design target. The reach for a secure hand-hold in in such moments is rapid and the opportunity to obtain a secure grasp to stop a stair fall is brief, giving import to the term readily graspable handrails. A beautiful complement to your railing system is a hardwood handrail. Thanks to reader M.S. 505.7.2 Non-Circular Cross Sections [handrailings].Handrail gripping surfaces with a non-circular cross section shall have a perimeter dimension of 4 inches (100 mm) minimum and 6 1/4inches (160 mm) maximum, and a cross-section dimension of 2 1/ Standard Specifications, Section 3214. Below are additional excerpts from the IRC, IBC, and Florida handrail codes: The non-circular handrail profile shown above is illustrated in the Florida Handrail code at 505.7.2. where the additional details are specified: 505.7.1 Circular Cross Section [handrailings].Handrail gripping surfaces with a circular cross section shall have an outside diameter of 1 1/4 inches (32 mm) minimum and 2 inches (51 mm) maximum. RDI 104 in. However in these larger sizes, the handrail must have a thumb and finger groove; Some older codes may permit the 2x6 handrail profile at far left in the illustration below, but as of 2009 the handrail needs a groove on both sides. Many years ago the handrail height … When we first climbed these stairs in 1960 there were still no handrailings. The railing height was 36″ net and the dimensions of the top rail member were 1.5″ x 1.75″. Conditions that may make a railing unsafe include termite damage, lead paint that no longer meets safety standards, railings on only one side of an open staircase, or railings too rickety to serve the intended purpose. This study aimed to perform a descriptive biomechanical analysis of maximal stair ascent in elderly women and to examine the relationship between mechanical muscle function and maximal stair ascending velocity (MAV). Thanks to reader M.S. The "stair rail" above is not just too big, not graspable, it's also too low. H. Sørensen, 505.9 Fittings: handrails shall not rotate within their fittings. A handrail made out of a 2x6 set flat and run along a stairway cannot be grasped. Group 1. There is no handrail, and when we have previously consulted regarding provision of a rope, it seems that we have to insert special cast iron bolts in the mortar (not the stonework) and the rope has to be fixed on the inside surface where the tread of the stair is at its narrowest. A 2x6" shape on edge, is also not readily graspable. We supply AC174 and IRC 311.5 compliant graspable handrail accessories. If the handrail is not circular, it shall have a perimeter dimension of at least 4 inches (102 mm) and not greater than 6.25 inches (160 mm) with a maximum cross-section dimension of 2.25 inches (57 mm). even where disabled individuals are not the design target. 7/26/90 is very often cited by other sources for good design of stairs and ramps etc. The most common dimension is 1.5″x 1.5″ for square members or 1.5″ diameter for round members. So while the diameter of the pipe may be fine, unless the piping is supported at intervals sufficiently close to keep it rigid and straight it may not form a good railing. used on stairs, balconies, decks, ramps, walks. It's funny until somebody trips or steps backwards and falls over such a psuedo-guardrail such as the one shown in my photo. 505.9 Fittings: handrails shall not rotate within their fittings.

Washington, DC 20210 These two sketches (above and below) are found in the California Building Code for stairs and railings [37]. Recapping from our article above in which we describe the shape and size parameters for stair handrails: That last item in our bulleted list means that code inspectors may approve a 2x6 or 2x4 hand railing placed in the vertical position (narrow dimension facing up - a width that can be readily grasped during a fall, while on flat it cannot - but the design needs to include a finger recess to permit a secure grip. The intent of the finger and thumb groove is to provide equivalent graspability as might be obtained on a round 2-inch handrail. All subjects showed a strong linear dependence on handrail height in generating stabilizing forces and moments. [9] "The Elimination of Unsafe Guardrails, a Progress Report," Elliott O. Stephenson, [11] The Stairway Manufacturers' Association, (877) 500-5759, provides a pictorial guide to the stair and railing portion of the International Residential Code. In our OPINION this remains an over-sized handrailing and even if approved by some inspectors, it is not as safe as one that can be grasped securely by wrapping the hand and fingers around the railing. fax to (202) 693-2498.

As we cited in OSHA's guidelines above, and as you will read in every expert source on proper stairway railing or "handrail" or "banister" design in our references at the end of this article, to be usable and functional, a handrailing must. M.S. But even when the stair-fall occurs for some other reason, if the falling person cannot maintain a grasp on the railing, that person is likely to suffer more serious injuries than if s/he might have had the opportunity to use a grasp on the handrail to stop the fall or to reduce its extent. We have no relationship with advertisers, products, or services discussed at this website. Functionally, the grooves on each side make the 6004 easy to grip while walking up or down the stairs.

Fernie, "Influence of Stairway Handrail Height on the Ability to Generate Stabilizing Forces and Moments", Human Factors: The Journal of the Human Factors and Ergonomics Society December 1984 vol. As you can see from our model's hand on top of the railing, the width of this particular rail, roughly 6", is too great to be grasped and held on-to should a stair fall occur. In that circumstance, an improper or unsafe railing is in one sense, worse than had there been no handrailing present at all, since in the latter case a stair user will have observed that there was no railing and may have been inclined to move more slowly and with greater care without that security, just as we are not inclined to step to the very edge of a tall balcony if no railings are installed on its perimeter. Above we show photographs of more non-graspable handrails that are unsafe: at Carnegie Hall in New York City, and just above, demonstrated by Asta S. in San Miguel de Allende, Mexico. The following opinions derive the author's experience in building stairs, inspecting stairs in and at buildings, in researching stair construction practices & building codes, and in the occasional assistance in the investigation of stair falls. My OPINION is that I agree emphatically with you that a railing on the inner side of a circular stair is more hazardous than the opposite in that it forces the stair user to walk on the inner and thus smaller portions of the stair treads - a more likely area for falls. Thanks, John [by private email] 2016/03/21. [38] Uniform Building Code Stair Specifications: UBC 1003.3.3.6 1997 or later specify handrail requirements, railing heights, rail widths, baluster spacing, stairway types, and guardrail specifications. Graspable secondary handrails are required by more and more building codes / deck codes in areas across the country.

Was this safety railing up to code in 1991? The non-graspable2x lumber handrail photographs shown above illustrate two more "wide handrailing" hazards: the rail is far too large (a nominal 2x6-inch flat railing) to be grasped by the hand. The California stair codes model the Uniform Building Code UBC 1003.3.3.6 1997 or later. It also will not comply with any of the model or actual building codes we cite above. Handrails should be graspable, continuous and smooth. The two-inch diameter of the PVC pipe is acceptable in terms of graspability as we see in this article. They are great for homes by providing a helping hand for family and friends to maneuver around your outdoor space. Some installers route a "thumb groove" into the sides of a 2x6 to make an attempt at improving graspability. One of my daughters fell down these curved stairs at the Galleria shopping mall (Poughkeepsie, NY) where the triangular tread hazard was combined with a beautiful, architect-designed handrail that was about 8" in diameter (photo at left, red arrow) - she was unable to grasp it as she was falling. Typically codes require a minimum of clearance of 1 1/2 inches between the inner surface of the handrailing and the adjacent wall. The shallow groove along the top of this handrail does not compensate for it being jammed up against the stairway wall. In addition, where the railing abuts a vertical surface (my middle two fingers in the photo) the user cannot even latch fingers around the outside of the "railing" - making it virtually useless.

Or use the SEARCH BOX found below to Ask a Question or Search InspectApedia. In short, as we demonstrate here, a simple 2x4 or 2x6, placed on edge along a stairway is not a graspable railing and so is not safe. Watch out: however in my opinion, long runs of un-supported PVC piping may be too flexible or may sag too much to be safely graspable and safely rigid to support a stairway user in the event of a fall. Some of these include a handrail whose profile is too wide or whose dimensions are too big for the hand to grasp, while others include using 2x lumber, a handrail that is too low or too high, or a handrail that is not spaced properly away from a building wall. 26 no.

U.S. Department of Labor Below is another example of a handrailing too close to the wall and not graspable, this one is in San Miguel de Allende, in Guanajuato. Generally, multi-joint CMJ parameters showed stronger correlations with MAV than single-joint isokinetic/isometric muscle strength parameters. Abstract: An experimental study was performed investigating the influence of handrail height on the ability of stairway users to generate stabilizing forces and moments, with the aim of improving stairway safety by developing better handrail design standards. Shown above/left: a water-filled handrailing along a stairway at the Alhambra in Spain. Handrails must be continuously graspable, with the expectation that the user doesn’t have to release the handrail in order to continue to the next flight of stairs. must be at the proper height above the steps (measured at the tread front nose), must be separated from the side wall (if present) at an adequate distance to permit the hand to grasp the railing, and. A person using stairs often does not think at all about railings and may not even touch them - until a fall begins. The expectation is that the user does not have to release the handrail to continue to the next flight of stairs. Here is a quick list of related guardrail or railing safety SNAFUs: We find a surprising number of handrailings that the installer must himself never have tried to grasp as they are so close to the wall that grasping is impossible. ANSI A117.4 Accessible and Usable buildings and Facilities (earlier version was incorporated into the ADA), ASTM F 1637, Standard Practice for Safe Walking Surfaces, (Similar to the above standard, [22] The Circular Staircase, Mary Roberts Rinehart, [23] Construction Drawings and Details, Rosemary Kilmer. A handrailing may be non-graspable for many reasons but most commonly because of these handrailing safety defects: Opinion: Daniel Friedman. If a railing cannot be securely gripped it is unsafe.

The 6004 Graspable Handrail is designed for both safety and style. Ability to generate forward/backward forces and forward/backward moments increased linearly with increasing handrail height. And as you can see below, my fat fingers don't fit into the space between the handrailing and the wall. One of the most frequent fall hazards we encounter are home-made railings that are too small or too large to grasp, or handrails that do not permit continuous grasping along their length. Seventeen healthy elderly women (age 72.4 ± 6.4) were tested for MAV, maximal multi-joint counter movement jumping (CMJ), and maximal single-joint isokinetic/isometric muscle moment. 6 705-714, Authors are at West Park Research, University of Toronto, Toronto, Canada. Our photo above illustrates a stair railing that is much to large to be securely grasped. General Physical Conditions and Structures Orders, fax to (202) 693-2498. By giving up some stairway width it's easy to fix this problem by adding a round or similarly-profiled handrailing at the proper height and fixed to the sides of the 2x6 by using handrail brackets. Telephone: (212) 777-0062 A handrail with edges, such as the top of a 2×4, can also be used as long as the sides of that 2×4 have indentions that can be considered “graspable” – the indentions must be at least 1 ¾” from the top fo the rail on both sides. It is not graspable. Someone else told me that because it's square it won't pass inspection. 200 Constitution Avenue, NW, N-3101 Above, the thumb is pressed against the vertical side of a 2x6, relying on friction alone for security - there is no mechanically-locking grasp of this railing - it is unsafe. This article illustrates several categories of handrailing graspability defects, all of which make a stairway unsafe. Explore. A graspable rail should not be smaller than 1.25″ or greater than 1.875″ in diameter. H. Sørensen, Telephone (202) 693-1888 or Some installers route a "thumb groove" into the sides of a 2x6 to make an attempt at improving graspability. The height of handrails must be installed 34 inches - 38 inches from the upper surface of the handrail to the surface of the tread. Volume 19, Issue 5, pages 678–686, October 2009. Article 17. And of course the railing must also be secured soundly to the structure. We think it is more dangerous on the central pillar than on the outer wall where the tread is widest. On the other hand if someone IS walking in that area, for sure that's the more hazardous area and so they'd want access to a railing.In general, ropes do no make very safe handrails because of their obvious lack of rigidity - better than nothing but not as secure as a solid material.
