When it comes to maintaining the productivity of your workplace, there`s nothing more important than safety. That`s why we`ve put together this guide to OSHA stair requirements. This information is useful across industries and helps you determine what is needed to keep your employees safe and your facility productive. The stair railing or ramp system is a barrier erected along the exposed or open side of stairs to prevent employees from falling to a lower level. PLATFORMS must have ≥ stair width and ≥GENERAL stairs 30″ deep ≥ 4` H or with 3 steps and 4 risers require a ramp/ramp system The step is the part of the staircase you are walking on. It can be made from a variety of patio materials that offer different traction. Have a minimum tread width of 7 inches (18 cm), measured at the leading edge of the tread (i.e. nose). BOAT STAIRS may only be used when standard stairs are impractical, 50-70 degrees, elevation 6.5″ « -11″, profile ≥ 4″, width ≥ 18 » 1910.25 (b) (2) The vertical distance above each stair step to an aerial obstacle is at least 6 feet, 8 inches (203 cm), measured from the leading edge of the tread. Spiral staircases shall comply with the headroom requirements set out in point (d)(3) of this Section. Answer #1: No.
Fixed stairs with a horizontal angle of 40 degrees with an 8-inch profile would not be acceptable. Fixed stairs with an 8-inch tread barrel with an elevation of 9.50 inches would be acceptable as they would create a horizontal angle of 49 degrees and 54 minutes, which is within the allowable range of 30 degrees to 50 degrees according to 29 CFR 1910.24 (e). OSHA`s specific stair requirements, including climb height, tread depth, profile nose, and landings, can be found in this article: OSHA Compliant Stairs: ErectaStep Industrial and Commercial Stairs. You can also read more about the difference between IBC and OSHA security codes here. For more information on OSHA compliance for stairs and walkways, visit the OSHA website. Definition. « Fixed stairs » means internal and external stairs for machinery, tanks and equipment, as well as stairs leading to or from floors, platforms or pits. This term does not apply to stairs intended solely for emergency exits, articulated stairs (whose angle changes with the rise and fall of the base support) or stairs that are an integral part of machinery. Answer #2: Yes. Fixed stairs comply with the standard if the climbing and profile dimensions result in a staircase with a horizontal angle of between 30 and 50 degrees.
Standard staircase. In addition to paragraph (b) of this section, the employer shall provide standard stairs: Restricted areas. If the physical characteristics require stairs steeper than those set out in paragraph (b)(1) of this section, stairs may be used at an angle of 50° to 75° to the horizontal if they are landings and platforms 1910.25(b)(4) at least the width of the staircase and at least 30 inches (76 cm) deep; measured in the direction of travel; Foot plates are screwed into the floor to secure the stair system. Question #1: However, would a fixed staircase with any angle to the 40-degree horizontal be acceptable for this question with an 8-inch profile barrel? 1910.25(b)(7) Standard stairs are used to provide access from one running work surface to another when operation requires regular and routine movement between levels, including access to equipment control platforms. Spiral stairs may be used on tanks and similar round structures if the diameter of the tank or structure is at least 5 feet (1.5 m). The employer is responsible for the safety of employees on fixed stairs such as roof access stairs, through stairs, loading ramp stairs, internal office stairs are all common workplace stairs. You must follow the rules described below. Have a minimum headroom above spiral stair steps of at least 6 feet, 6 inches (2 m), measured from the leading edge of the tread; Question #3: Would fixed stairs with an angle between 38 degrees and 42 degrees match 29 CFR 1910.24(e) if they have an elevation of 7.07 to 8.15 inches and a tread barrel of 9.05 inches? Example #1: Fixed staircase with an angle of 39 degrees and a climb of 7.08 inches with a stroke of 9.05 inches. Example #2: Fixed staircase with an angle of 42 degrees and a climb of 8.15 inches with a stroke of 9.05 inches. Derogation from paragraphs (c) (2) and (3) of this section. The requirements of paragraphs (c)(2) and (3) do not apply to standard stairs installed before January 17, 2017.
OSHA considers these stairs to be compliant if they meet the dimensional requirements set out in Table D-1 of this section or use a combination that meets the angular requirements of paragraph (c)(1) of this section. Application. This section includes all stairs (including standard, spiral, boat and alternate tread stairs), except articulated stairs (stairs that change inclination due to changes in height at the mounting point), such as stairs for floating roof tanks, stairs on scaffolding, stairs designed for machinery or equipment, and stairs for self-propelled motorized equipment. have handrails that meet the requirements of Section 1917.112(c)(1) on both sides and are at least 30 inches (76.2 cm) from the tread on the riser. Climb height – 9.5 inches (24 cm) – 1910.25 (d) (2) Stair width of at least 22 inches (55 cm) – 1910.25 (c) (4) Tread depth of at least 9.5 inches (24 cm) – 1910.25 (c) (3) Landings at least the width of stairs. 1910.25(b)(4) ErectaStep`s modular metal stairs and industrial maintenance access platforms feature modular and lightweight metal staircase components that are as easy to reconfigure as they are to assemble. One of the components of ErectaStep is the screwing of aluminum ladders. ErectaStep also has a range of commercial stairs with OSHA or IBC compliance options If paragraph (b)(8) of this section permits the use of spiral, ship, or interchangeable stairs, they must be installed, operated, and maintained in accordance with the manufacturer`s instructions. To find out if your tread is compliant, answer the following questions: As an employer, it is mandatory to have a fall protection system if there is an unprotected edge that is 4 feet or more away from a lower level. Guardrails are the most commonly used fall protection system for stairs. 1910.25(b)(6) Each staircase may carry at least five times the normal intended payload, but not less than a concentrated load of 1,000 pounds (454 kg) at any given point; Spiral, boat or exchange stairs are only used if the employer can demonstrate that it is not possible to provide standard stairs.
1910.25(b) General Requirements. The employer must ensure: 1910.25 f) Alternating walking. In addition to clause (b) of this section, the employer shall ensure that stairs are staggered alternately, 1910.25 (f) (1) Have a series of steps installed on a slope of 50 to 70 degrees from the horizontal; 1910.25(b)(5) Where a door or gate opens directly onto a staircase, a platform shall be provided and the flapping of the door or gate shall not reduce the effective useful depth of the platform to To ensure that the nose is visible (color), to the dimensions of the actual staircase, landing and ramp that are built in connection. In Subdivision D of Part 1910 of the Occupational Health and Safety Standards, accessible work surfaces for stationary industrial stairs are discussed. Thank you for your letter dated October 11, 2011 to the Occupational Safety and Health Administration (OSHA) to clarify the OSHA Standard for Fixed Industrial Stairs, 29 CFR 1910.24. This is OSHA`s interpretation of the requirements discussed only and may not apply to matters not described in your original correspondence. Note: If the top edge of a stair railing system is also used as a handrail, paragraph (c)(7) of this section applies. RAILINGS open stairs 44″ require 1 ramp and 1 separate handrail / Page 1910.25 (b) (1) Handrails, stair railings and guardrail systems are provided in accordance with § 1910.28; Platforms can be placed at the top, center or bottom of a metal staircase.
