When safety devices are provided, the maximum clearance distance between side rail extensions must not exceed 36 inches (91 cm). (1910.25(b)(3)), The minimum tread depth is 9.5 inches. Handrails must provide an adequate handhold for employees to grasp to prevent falls. Stairs ≥ 2200mm (87 inches) require an intermediate handrail such that a user is no more than 825mm (32 inches) from a handrail. (If installed before March 15, 1991, not less than 30 inches [76 cm]). Handrail and Stair Rail Systems • If a stair has a minimum of four risers, a handrail is required. (If installed before March 15, 1991, not less than 30 inches [76 cm]). Minimum perpendicular clearance between the centerline of fixed ladder rungs, cleats and steps, and any obstruction on the climbing side of the ladder must be 30 inches (76 cm). Guardrail systems that exceed 45 inches in height are compliant if the openings are less than 19 inches and they meet the other requirements. U.S. Department of Labor | Occupational Safety & Health Administration | 200 Constitution Ave., NW, Washington, DC 20210. Wells must completely encircle the ladder. In the U.S., the I-Codes require handrail placed between 34 and 38 inches. Stair Rails and Handrails. The building code requirement for stair railings typically requires handrailings on stairs that have a total rise of three feet or more. But stepping off the bottom step (or preparing to step up on it) is actually when someone is the most off balance and likely to fall. Requirements for handrails are as follows: Handrails and top rails of the stair rail systems must be able to withstand, without failure, least 200 pounds (890 n) of weight applied within 2 inches (5 cm) of the top edge in any downward or outward direction, at any point along the top edge. Bottoms of cages must be between 7 feet (2.1 m) and 8 feet (2.4 m) above the point of access to the bottom of the ladder. (1910.29(b)(1)), Platform Midrail Height: A system must be put between the steps and the top guardrail to prevent an employee from falling through. Use at least one hand to grasp the ladder when climbing. Mountings for flexible carriers must be attached at each end of the carrier. Use ladders only for their designed purpose. Side rails of through or side-step fixed ladders must extend 42 inches (1.1 m) above the top level or landing platform served by the ladder. A landing platform must be provided if the step-across distance exceeds 12 inches (30 cm). By contrast, deck code is truly a matter of life and death and preventing serious injury. Or use a barricade to keep traffic or activity away from the ladder. Side rails and steps or rungs for side-step fixed ladders must be continuous in extension. As an employer, there is a duty to have a fall-protection system in place when there is an unprotected edge that is 4 or more feet from a lower level; guardrails are the most common fall-protection system used for stairs. Safety Handrails: A Showerhead Grab Bar is a Big Help. (1910.25(c)(3)), The minimum tread width is 22 inches between the stringers. Tops of cages must be a minimum of 42 inches (1.1 m) above the top of the platform or the point of access at the top of the ladder. For example, stairs manufactured with a 45-degree stairway rise must have a minimum rise and tread of 8.75 inches each. GENERAL stairs ≥ 4’ H or w/3 treads and 4 risers require a stair rail/stair rail system Inside faces of wells on the climbing side of the ladder must extend between 27 inches (68 cm) and 30 inches (76 cm) from the centerline of the step or rung. Maintain ladders free of oil, grease and other slipping hazards. The height is measured vertically from the line connecting the nosing. All treads and landings must be replaced when worn below the top edge of the pan. Use ladders only on stable and level surfaces unless secured to prevent accidental movement. Guardrails with a top-edge height less than 39 inches are not permitted. Minimum perpendicular clearance between fixed ladder rungs, cleats, and steps and any obstruction behind the ladder must be 7 inches (18 cm), except that the clearance for an elevator pit ladder must be 4.5 inches (11 cm). Cable guides for flexible carriers must be installed with a spacing between 25 feet (7.6 m) and 40 feet (12.2 m) along the entire length of the carrier, to prevent wind damage to the system.Design and installation of mountings and cable guides must not reduce the strength of the ladder. When there is a break in elevation of 19 inches (48 cm) or more and no ramp, runway, embankment or personnel hoist is available, employers must provide a stairway or ladder at all worker points of access. States with approved programs must have a standard that is identical to, or at least as effective as, the federal standard. (a) Stairways shall have handrails or stair railings on each side, and every stairway required to be more than 88 inches in width shall be provided with not less than one intermediate stair railing for each 88 inches of required width. Ship, spiral, and alternating tread-type stairs are not considered standard stairs. STAIRS – OSHA Requirements Standard stair means a fixed or permanently installed stairway. The requirements for stair and ramp handrails in this document are for adults. Screens or mesh, when used, must extend from the top rail to the stairway step and along the opening between top rail supports. (1910.25(b)(4)), Depth: Platforms must be at least 30 inches deep, as measured in the direction of travel. surfaces. OSHA stairs are required to be a minimum of 22 inches wide. 4.2 Railing that meets the requirements of this Practice is designed to withstand a concentrated load of 200 pounds (890 N) applied in any direction at any point along the top rail, in accordance with OSHA requirements. Standard railings shall be provided on the open sides of all exposed stairways and stair platforms. According to OSHA requirements for stairs, employers must install stair rails on stairs with four or more risers or a height higher than 30 inches, whichever is less. Handrails, stair rail systems, and guardrail systems are provided in accordance with § … All safety devices must be activated within 2 feet (.61 m) after a fall occurs and limit the descending velocity of an employee to 7 feet/second (2.1 m/sec) or less. Ladder repairs must restore the ladder to a condition meeting its original design criteria before the ladder is returned to use. *These states and territories operate their own OSHA-approved job safety and health programs (Connecticut, New Jersey and New York plans cover public employees only). Ladder components must be surfaced to prevent snagging of clothing and injury from punctures or lacerations. Footplates are bolted into the ground to secure the stair system. In addition, employers must install all stairway and ladder fall protection systems required by these rules and ensure that their worksite meets all requirements of the stairway and ladder rules before employees use stairways or ladders. Cages must not extend less than 27 inches (68 cm), or more than 30 inches (76 cm) from the centerline of the step or rung and must not be less than 27 inches (68 cm) wide. Metal spreader or locking devices must be provided on stepladders to hold the front and back sections in an open position when ladders are being used. Handrail Height. Stairways that will not be a permanent part of the building under construction must have landings at least 30 inches deep and 22 inches wide (76 x 56 cm) at every 12 feet (3.7 m) or less of vertical rise. Inside widths of wells must be at least 30 inches (76 cm). Ends of stair rail systems and handrails must be built to prevent dangerous projections, such as rails protruding beyond the end posts of the system. Intermediate stair railings shall be spaced approximately equal within the entire width of the stairway. Under 1910.24, OSHA prescribes the use of handrails and railings as fall protection. Rungs of individual rung/step ladders must be shaped to prevent slipping off the end of the rungs. The midrail must be installed at a height midway between the top edge of the guardrail and the walking surface. Winding or spiral stairways must have a handrail to prevent use of areas where the tread width is less than 6 inches (15 cm). In addition to paragraph (b) of this section, the employer must ensure standard stairs: 1910.25 (c) (1) Are installed at angles between 30 to 50 degrees from the horizontal; 1910.25 (c) (2) Have a maximum riser height of 9.5 inches (24 cm); 1910.25 (c) (3) Have a minimum tread depth of 9.5 inches (24 cm); and. Temporary handrails must have a minimum clearance of 3 inches (8 cm) between the handrail and walls, stair rail systems and other objects. Stairways shall have a minimum of one.

Intermediate vertical members, such as balusters used as guardrails, must not be more than 19 inches (48 cm) apart. b. Handrails. When it comes to residential stair standards, the International Residential Code (IRC) establishes minimum requirements for stairs to insure a level of safety to the public. (7) All parts of stairways shall be free of hazardous projections, such as protruding nails. Workers must not use spiral stairways that will not be a permanent part of the structure. OSHA does not require solid risers, so most companies choose to have open-back risers because that style is typically less expensive. Minimum clear distance between the sides of individual rung/step ladders and between the side rails of other fixed ladders must be 16 inches (41 cm). • Stair rail system: • Top rail may also serve as handrail if height of … (See Section 3214 for stair rail and handrail specifications and Section 3234 for industrial stairways). Rungs, cleats and steps at the base section of. Step Guardrail Height: Unlike ADA guidelines, the guardrails in OSHA steps also act as the handrails when the top edge of the guardrail is between 36 and 38 inches above the leading edge of the stair tread. Fixed ladders must be able to support at least two loads of 250 pounds (114 kg) each, concentrated between any two consecutive attachments. 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. Slippery conditions on stairways must be corrected. • Handrails must be between 30 and 38 inches as measured from the leading edge of the stair tread. Dimensional details of railing members of a few types of construction which comply with this strength requirement are given hereinafter in subsection (c). Use ladders equipped with nonconductive side rails if the worker or the ladder could contact exposed energized electrical equipment. Defective fixed ladders are considered withdrawn from use when they are immediately tagged with "Do Not Use" or similar language, or marked in a manner that identifies them as defective, or blocked- such as with a plywood attachment that spans several rungs. Stair rails installed after March … Vertical bars must be spaced at intervals not more than 9.5 inches (24 cm), measured centerline to centerline. The bottom of the cage must be flared not less than 4 inches (10 cm) between the bottom horizontal band and the next higher band. Do not use slipresistant feet as a substitute for exercising care when placing, lashing or holding a ladder upon slippery surfaces.

Two or more separate ladders used to reach an elevated work area must be offset with a platform or landing between the ladders, except when portable ladders are used to gain access to fixed ladders. Stair rail systems and handrails must be surfaced to prevent injuries such as punctures or lacerations and to keep clothing from snagging. Keep areas clear around the top and bottom of ladders. Do not carry objects or loads that could cause loss of balance and falling. Parapet ladders must have an access level at the roof if the parapet is cut to permit passage through it. Step-across distance between the center of the steps or rungs of fixed ladders and the nearest edge of a landing area must be no less than 7 inches (18 cm) and no more than 12 inches (30 cm). railing for regular operational use, special fabrication details, and any changes to the requirements of this Practice. Do not use cross bracing on the rear section of stepladders for climbing unless the ladders are designed and provided with steps for climbing on both front and rear sections. Horizontal bands must be fastened to the side rails of rail ladders or directly to the structure, building or equipment for individual-rung ladders. The handrails for exterior stairs typically end at the bottom step. (1910.29(b)(2)), Tread depths must be the same between each landing platform. A handrail must be between 865mm and 1070mm (34 and 42 inches) above the nosing. (1910.25(c)(4)), Riser heights must be the same between each landing platform. When the top edge of a stair rail system also serves as a handrail, the height of the top edge must be no more than 37 inches (94 cm) nor less than 36 inches (91.5 cm) from the upper surface of the stair rail to the surface of the tread. If obstructions are unavoidable, clearance may be reduced to 24 inches (61 cm), provided a deflection device is installed to guide workers around the obstruction. Risers make up the vertical area between step treads. Fixed ladders must be provided with cages, wells, ladder safety devices or self-retracting lifelines where the length of climb is less than 24 feet (7.3 m) but the top of the ladder is at a distance greater than 24 feet (7.3 m) above lower levels.

Stairways with four or more risers, or that rise more than 30 inches (76 cm) in height- whichever is less- must have at least one handrail. continuous handrail mounted between 30 inches and 36. inches above the floor or tread. 1. Mountings for rigid carriers must be attached at each end of the carrier, with intermediate mountings spaced along the entire length of the carrier, to provide the necessary strength to stop workers' falls. Secure ladders placed in areas such as passageways, doorways or driveways, or where they can be displaced by workplace activities or traffic to prevent accidental movement. All safety devices must permit the worker to ascend or descend without continually having to hold, push or pull any part of the device, leaving both hands free for climbing. wider than 88 inches shall additionally have an. Basic Handrail Spacing & … If free passage becomes restricted, employers must provide a second point of access and ensure that workers use it. Just because a railing exists doesn't mean it will pass FHA standards. Bottoms of wells above the point of access to the bottom of the ladder must be between 7 feet (2.1 m) and 8 feet (2.4 m). Vertical bars must be on the inside of the horizontal bands and must be fastened to them. As for guards along a set of stairs that serve as a handrail as well, they are allowed to be at a height of no less than 34 inches but no more than 38 inches. Stair rails installed after March 15,1991, must be not less than 36 inches (91.5 cm) in height. It can be made from a multitude of decking materials that offer various degrees of traction.

Guardrails do not have a height limitation, except for when they serve as a handrail in addition to a guardrail. (6) Metal pan landings and metal pan treads, when used, shall be secured in place before filling with concrete or other material. OSHA 1910.29 (b) contains system requirements that employers must follow to ensure guardrail systems will protect workers from falling to lower levels: 1910.29 (b) (1) The top edge height of top rails, or equivalent guardrail system members, are 42 inches (107 cm), plus or minus 3 inches (8 cm), above the walking working surface. The top-edge height of a guardrail may exceed 45 inches if it … (1910.25(b)(5)(i) & 1910.25(b)(5)(ii)), Step Guardrail Height: Unlike ADA guidelines, the guardrails in OSHA steps also act as the handrails when the top edge of the guardrail is between 36 and 38 inches above the leading edge of the stair tread. Several components are looked at such as stair width, headroom, riser and tread heights. Stair treads shall have non-slip. The preamble to the final rule states: Risers can be solid or open-back depending on the required compliance code. Fixed ladders without cages or wells must have at least a 15-inch (38 cm) clearance width to the nearest permanent object on each side of the centerline of the ladder.

OSHA regulates every factor about a workplace, and below you will find the code that we follow for our fixed, industrial stairs. References (a) Every flight of stairs having four or more risers or rising thirty inches, whichever is less, shall be equipped with stair railings or handrails as specified in paragraphs (F)(6)(a)(i) to (F)(6)(a)(i)(v) of this rule, the width of the stair to be measured clear of all obstructions except handrails. Midrails are commonly used in conjunction with the top guard rail. Building code requirements for exterior decking railings and stairways are especially stringent because decks fall into the category of critical health and safety matters. When children are the principal users in a building or facility (e.g., elementary schools), a second set of handrails at an appropriate height can assist them and aid in preventing accidents. Fixed ladders with structural defects- such as broken or missing rungs, cleats or steps, broken or split rails or corroded components- must be withdrawn from service until repaired. Do not move, shift or extend ladders while in use. Each step or rung of a fixed ladder must be able to support a load of at least 250 pounds (114 kg) applied in the middle of the step or rung. Handrails shall be provided on at least one side of closed stairways preferably on the right side descending.
