Each suspension rope, including connecting hardware, used on adjustable suspension scaffolds shall be capable of supporting, without failure, at least 6 times the maximum intended load applied or transmitted to that rope with the scaffold operating at either the rated load of the hoist, or 2 (minimum) times the stall load of the hoist, whichever is greater. Scaffolds shall be erected, moved, dismantled, or altered only under the supervision and direction of a competent person qualified in scaffold erection, moving, dismantling or alteration. OSHA’s scaffolding standards lay out safe and proper methods for scaffolding used in construction jobs. In these situations, only the planking that the employer establishes is necessary to provide safe working conditions is required. Guardrail systems installed to meet the requirements of this section shall comply with the following provisions (guardrail systems built in accordance with Appendix A to this subpart will be deemed to meet the requirements of paragraphs (g)(4)(vii), (viii), and (ix) of this section): Guardrail systems shall be installed along all open sides and ends of platforms. This provision does not preclude the use of systems which are designed to function both as suspension scaffolds and emergency systems. A tower scaffold is an independent scaffold that has four vertical standards connected longitudinally and transversely, or two frames in plan connected transversely to create a scaffold of one bay. Midrails must be installed approximately halfway between the toprail and the platform surface. She's a HUGE sugar junkie...and usually starts wandering the halls looking for cookies around 3pm daily. Greater variations in riser height are allowed for the top and bottom steps of the entire system, not for each flight of stairs. The height of the toprail for scaffolds manufactured and placed in service before January 1, 2000 can be between 36 inches (0.9 meters) and 45 inches (1.2 meters). OSHA categorizes scaffolds into three basic types: Supported scaffolds, which consist of one or more platforms supported by rigid, load- bearing members, such as poles, legs, frames, and outriggers. All- in- one system designed to engage your employees, instill a culture of safety, and enable regulatory compliance. When the loads specified in paragraph (g)(4)(vii) of this section are applied in a downward direction, the top edge shall not drop below the height above the platform surface that is prescribed in paragraph (g)(4)(ii) of this section. Paragraph (g)(2) of this section addresses fall protection for scaffold erectors and dismantlers. Before the scaffold is used, direct connections shall be evaluated by a competent person who shall confirm, based on the evaluation, that the supporting surfaces are capable of supporting the loads to be imposed. Abrasion, corrosion, scrubbing, flattening or peening causing loss of more than one-third of the original diameter of the outside wires. Swaged attachments or spliced eyes on wire suspension ropes shall not be used unless they are made by the wire rope manufacturer or a qualified person. You work in construction: Scaffolds are commonplace in the construction industry. The use of repaired wire rope as suspension rope is prohibited. Toeboards shall be solid or with openings not over one inch (2.5 cm) in the greatest dimension. Millions of construction workers across the US work on scaffolds every year. Employers are required to provide fall protection for employees erecting or dismantling supported scaffolds where the installation and use of such protection is feasible and does not create a greater hazard. As discussed above, faulty and badly-maintained equipment is a leading cause of scaffolding accidents. Supported scaffold poles, legs, posts, frames, and uprights shall bear on base plates and mud sills (or other adequate firm foundation). consist of one or more platforms held up by rigid structural elements such as. Except as provided in paragraphs (b) (2) (i) and (b) (2) (ii) of this section, each scaffold platform and walkway shall be at least 18 inches (46 cm) wide. Available sizes for Scaffolding Standards : 3.0m, 2.5m, 2.0m, 1.80m, 1.50m,1.30m & 1.0m Makeshift devices, such as but not limited to boxes and barrels, shall not be used on top of scaffold platforms to increase the working level height of employees. Portable, hook-on, and attachable ladders (Additional requirements for the proper construction and use of portable ladders are contained in subpart X of this part -- Stairways and Ladders): Portable, hook-on, and attachable ladders shall be positioned so as not to tip the scaffold; Hook-on and attachable ladders shall be positioned so that their bottom rung is not more than 24 inches (61 cm) above the scaffold supporting level; When hook-on and attachable ladders are used on a supported scaffold more than 35 feet (10.7 m) high, they shall have rest platforms at 35-foot (10.7 m) maximum vertical intervals. Guys, ties, and braces shall be installed according to the scaffold manufacturer's recommendations or at the closest horizontal member to the 4:1 height and be repeated vertically at locations of horizontal members every 20 feet (6.1 m) or less thereafter for scaffolds 3 feet (0.91 m) wide or less, and every 26 feet (7.9 m) or less thereafter for scaffolds greater than 3 feet (0.91 m) wide. Excess suspension wire rope and any additional independent lines from grounding shall be insulated; The suspension wire rope shall be covered with insulating material extending at least 4 feet (1.2 m) above the hoist. Any object resting on or above a scaffold can fall and become deadly. Employee complaints are the number 1 reason why OSHA decides to investigate employers. Scaffolding is riskier during storms and periods of high wind, as well as immediately after rain or snowfall. In this series, we’re exploring the most common OSHA violations, one by one. Treads and landings shall have slip-resistant surfaces. Scaffold-related fatalities account for a significant number of fatalities in the construction workplace.” (Source). General Industry. Toeboards shall be securely fastened in place at the outermost edge of the platform and have not more than 1/4 inch (0.7 cm) clearance above the walking/working surface. Note to paragraph (b)(2)(i): Pursuant to an administrative stay effective November 29, 1996 and published in the Federal Register on November 25, 1996, the requirement in paragraph (b)(2)(i) that roof bracket scaffolds be at least 12 inches wide is stayed until November 25, 1997 or until rulemaking reguarding the minimum width of roof bracket scaffolds has been completed, whichever is later. Steel or plastic banding shall not be used as a toprail or midrail. Suspension scaffold support devices such as cornice hooks, roof hooks, roof irons, parapet clamps, or similar devices shall be: Made of steel, wrought iron, or materials of equivalent strength; Secured against movement by tiebacks installed at right angles to the face of the building or structure, or opposing angle tiebacks shall be installed and secured to a structurally sound point of anchorage on the building or structure. OSHA’s “Safety Standards for Scaffolds Use in the Construction Industry” has several key provisions. Ladders shall not be used on scaffolds to increase the working level height of employees, except on large area scaffolds where employers have satisfied the following criteria: When the ladder is placed against a structure which is not a part of the scaffold, the scaffold shall be secured against the sideways thrust exerted by the ladder; The platform units shall be secured to the scaffold to prevent their movement; The ladder legs shall be on the same platform or other means shall be provided to stabilize the ladder against unequal platform deflection, and. The end points at each upright shall be no more than 48 inches (1.3 m) apart. Debris shall not be allowed to accumulate on platforms. Non-mandatory Appendix A to this subpart contains examples of criteria that will enable an employer to comply with paragraph (a) of this section. Wind screens shall not be used unless the scaffold is secured against the anticipated wind forces imposed. Our experienced Safety Compliance Specialists are knowledgeable of scaffolding safety compliance requirements and can help your company ensure compliance with OSHA’s scaffold related standards, 1910 Subpart D for general industry, and 1926 Subpart L for construction. Any part of a scaffold damaged or weakened such that its strength is less than that required by paragraph (a) of this section shall be immediately repaired or replaced, braced to meet those provisions, or removed from service until repaired. Inspectors will also be working with scaffold suppliers and installers to ensure scaffolds are built to standard and are safe. However, the alternative methods must provide equivalent safety to those specified in this standard. Unstable objects shall not be used as working platforms. Hook-on or attachable ladders shall be installed as soon as scaffold erection has progressed to a point that permits safe installation and use. Suspension scaffold outrigger beams shall be: Provided with stop bolts or shackles at both ends; Securely fastened together with the flanges turned out when channel iron beams are used in place of I-beams; Installed with all bearing supports perpendicular to the beam center line; Set and maintained with the web in a vertical position; and. OSHA 1926.454(c) states: When an employer has reason to believe that an employee lacks the skill or understanding needed for safe work involving the erection, use or dismantling of scaffolds… The size of this conductor shall be at least the size of the welding process work lead, and this conductor shall not be in series with the welding process or the work piece; If the scaffold grounding lead is disconnected at any time, the welding machine shall be shut off; and. Fall protection or fall arrest systems.

Each employee more than 10 feet above a lower level must be protected from falls by guardrails or a fall arrest system, except those on single-point and two-point adjustable suspension scaffolds. Toby manages the marketing communications team here at KPA. Tread depth shall be uniform, within 1/4 inch, for each flight of stairs. No more than two workers may occupy a platform at any one time. Scaffold components manufactured by different manufacturers shall not be intermixed unless the components fit together without force and the scaffold's structural integrity is maintained by the user. Your business is subject to many operational, regulatory, and compliance risks. When screens and mesh are used, they shall extend from the top edge of the guardrail system to the scaffold platform, and along the entire opening between the supports. Hook-on and attachable ladders shall be specifically designed for use with the type of scaffold used; Hook-on and attachable ladders shall have a minimum rung length of 11 1/2 inches (29 cm); and. Scaffolding is riskier during storms and periods of high wind, as well as immediately after rain or snowfall. Suspension scaffold outrigger beams, when used, shall be made of structural metal or equivalent strength material, and shall be restrained to prevent movement. The toprail of each stairrail system shall also be capable of serving as a handrail, unless a separate handrail is provided. Such activities shall be performed only by experienced and trained employees selected for such work by the competent person. Each platform greater than 10 feet in length shall not extend over its support more than 18 inches (46 cm), unless it is designed and installed so that the cantilevered portion of the platform is able to support employees without tipping, or has guardrails which block employee access to the cantilevered end.
