Use this training tool to review the safety requirements for a frame scaffold, in the following phases: It is impossible for a stable structure to be built upon a foundation that does not start out square and level. (True or False) _____ 2. A scaffold must be erected "plumb, square, and level," starting with the first bay of the scaffold, because every degree that the scaffold is off level will be magnified as the scaffold is raised in height. In such cases, the platforms must be as wide as feasible, and fall protection must be provided. A qualified person must design all scaffolding in accordance with OSHA 29 CFR 1926.451 "General Requirements for Scaffolds" and 29 CFR 1926.452 "Additional . Duty level of scaffold is based on the chart below. d. Scaffold legs shall be set on adjustable bases or plain bases placed on mud sills or other foundations adequate to support the maximum intended load. Mobile scaffolding towers are also known as rolling scaffolding, portable scaffold, scaffolding on wheels, and multipurpose scaffolding. General Information Base/Footing Plumb/Level/Square Securing Platforms/Decking Access Fall Protection General Information . One exception is when the scaffold platform is within 14 inches of the face of the work. NOTE: Except where indicated, these requirements also apply to manually propelled, pump jack, ladder jack, tube and coupler, and pole scaffolds as well as the specialty scaffolds described in the Supported Scaffolds module. Light-duty scaffolds can support 25 pounds per square foot. This individual must supervise all scaffold assemblies, changes, movement, or dismantling. Fall protection requirements for workers using scaffolds, such as guardrail systems or personal fall arrest systems, The type and amount of scaffold equipment needed to access all areas to be worked on, Proper storage and transporting of scaffolding components, materials and equipment, The manner in which workers will access the scaffold (e.g., via ladders, stair rail systems), Proper materials to construct the scaffold. In general, a level is the easiest way to achieve the desired right angles. Scaffolds need to be erected plumb, level, squared and braced to . Scaffolds are generally rated as light, medium or heavy duty and must be able to support the correlating weight of workers and materials required for each type. [, Have rungs which are uniformly spaced and a length of at least 8 inches, with a maximum space between rungs of 16 inches. Improper Access Leads to Serious Injuries. [, Portable, hook-on, and attachable ladders must be positioned so as not to tip the scaffold. Canopy structures made of solid materials. A scaffold can be overloaded by [. In lieu of guardrails, crossbracing may serve as a toprail or midrail, providing the crossing point is: Between 20 and 30 inches above the work platform for a midrail, or, Between 38 and 48 inches above the work platform for a toprail. Guardrails must be installed on scaffolding over 10'. Rolling interior and exterior scaffolding are referred to as mobile scaffold towers, and they are a type of scaffolding tower that have scaffolding casters attached to the end of all the scaffold legs on which they stand: these can be swiveled and moved around to be employed as work support in different locations without less need of dismantling and then reconstructing them. Install guys, ties and braces according to the manufacturers recommendations. Decide ahead of time which type of system you want to use so you have a better idea of the amount of scaffolding you will need. [, Nothing that could cause a slip, trip or fall (i.e. [, Scaffold components made of dissimilar metals must not be used together unless a competent person has determined that galvanic action will not reduce the strength of any component below OSHA standards. Workers building scaffolds risk serious injury from falls and tip-overs, being struck by falling tools and other hazards and electrocution from energized power lines. Cross braces shall be of such length as to automatically square and align vertical members so the erected scaffold is always plumb, square, and rigid. [, Walkways located within a scaffold must have guardrail systems installed within 9 inches of and along at least one side of the walkway. Tube and coupler scaffold design must comply with 29 CFR 1926.451-.452. Therefore, an inspection of a scaffold platform requires safety checks of both the platform structure and how the platform is used by the workers. Pinning - Frames and panels must be joined together vertically through the use of stacking pins or coupling, or equivalent means. Guys, ties and braces shall be installed where horizontal members support both inner and outer legs. He fell 16 feet to the ground, sustaining facial fractures and other injuries. Personal fall arrest systems used on scaffolds are required when the guardrail system is incomplete or does not provide adequate protection. Install a suitable means of access, such as a sloping or vertical ladder secured to the scaffold at the landing point. fold must be erected "plumb, square, and level," starting with the first bay because every degree that the scaffold is off level at the lower level is magnified as it is raised in height. [, If a ramp or walkway has a slope of more than 1:8, it must have cleats securely fastened to the planks not more than 14 inches apart, to provide footing. [, Forklifts shall not be used to support scaffold platforms unless [. [, Any part of a scaffold that has been damaged or weakened so that it no longer meets OSHA strength requirements must either be repaired, replaced, braced, or removed from service. [, Have rest platforms provided at a maximum of 35-foot vertical intervals. [29 CFR 1926.451(e)(9)(i)]. Each section of the framework measured 6'5" high. Each frame or panel shall be braced by horizontal bracing, cross bracing, diagonal bracing or any combination thereof for securing vertical members together laterally. (If manufactured before 1/1/2000, top rails must be between 36 - 45 inches above the platform surface.) Check the level again and plumb if necessary. Place the planks. Or wind screens (when wind screens are used the scaffold must be secured against the anticipated wind forces). or more per square foot. The space between planks cannot exceed 1 inch, except where necessary for obstructions. Safe points of anchorage include structural members of buildings, but not standpipes, vents, electrical conduit, etc., which may give way under the force of a fall. Ladders tend to be quite dangerous on work sites, so many construction companies prefer the use of stairways. perfectly vertical) and braced to prevent swaying and displacement. The scaffold was not secured to wooden footing supports, nor was it tied to the building. It is not all-inclusive and should be used as a starting point for the competent person to develop a checklist specific to the type of scaffold and jobsite conditions encountered. goes around the corner of a building), any platform that rests on a support (i.e. Each frame or panel shall be braced by horizontal bracing, cross bracing, diagonal bracing or any combination thereof for securing vertical members together laterally. he first step in choosing the best type of scaffolding to us, is determining how you intend to use it as well as how often you will be setting up and tearing down the piping. . Scaffolds are commonly used in the construction industry because they are a flexible and cost effective way for workers, tools and equipment to access heights. (. [, Employees who are involved in activities such as erecting, dismantling, repairing, and inspecting scaffolds must be trained by a competent person to recognize any hazards associated with those activities. The size of the mud sill shall be based on the type of soil the scaffold will be erected upon. Catenary Scoffold. Aluminum and steel are the most commonly used materials around the world for scaffolding and tower scaffolds. Even if they are "in the way," braces should not be removed while work is being performed on a scaffold! Fasten all couplers and/or connections . Footing. Check out our special shipping rates! Tube and coupler scaffolds over 125 feet in height must be designed by a registered professional engineer. [29 CFR 1926.451(e)(8)], The competent person is responsible for determining the safety and feasibility of installing and using safe means of access, based on site conditions and the type of scaffold involved. Employees must not work on platforms covered with snow, ice or other slippery material. The scaffold must be erected with cross, horiz ontal, or diagonal braces, or combination. 2. This risk can be removed through proper clearance and maintenance. When dismantling the scaffold, check to ensure that the scaffold has not been structurally altered in a way that would make it unsafe. In addition, the scaffold and its components must support, without failure, its own weight and at least four times its maximum intended load. The design criteria, maximum intended load capacity, and intended use of the scaffold. Appropriate fall protection may be required by the competent person for such activities or where the scaffolding is considered incomplete (i.e. Unsafe scaffolding has the potential to result in death or serious . Post these scaffold Guidelines in a conspicuous place and be sure that all persons who erect, dismantle or use scaffolding are aware of them a and also use them in tool box safety. Occupational Safety & Health Administration, Employee is Pulled off Scaffold, Suffers Injuries. They are frequently used in one or two tiers by residential contractors, painters, etc., but their modular frames can also be stacked several stories high for use on large-scale construction jobs. Such retraining is required in at least the following situations [. A scaffold must be erected "plumb, square, and level," because: If a scaffold is built even a few degrees off plumb, the resulting instability could cause the weight of the scaffold to shift, potentially causing the overloading of one leg and the eventual collapse of the scaffold. Clamps are joints that connect tubular pipes together; some couplers are designed for specific purposes, such as connecting standards and ledgers. [, Fall protection consists of either personal fall arrest systems or guardrail systems meeting OSHA requirements. For lathing and plastering, a gap of 18 inches is permitted. [, Employees performing overhand bricklaying operations from a supported scaffold must be protected from falling from all open sides and ends of the scaffold, except at the side next to the wall being laid. [, A landing platform at least 18 inches wide by 18 inches long at each level. Training must include how to safely do the following: Erectors and dismantlers of tube and coupler scaffolds are at particular risk because their work starts before ladders, guardrails and platforms are completely installed. Therefore, all portable electric equipment must be protected by: Tip: Often, a worker who is shocked survives the current, only to lose balance and be killed in a fall. [, Frames and panels must be locked together to prevent uplift, where uplift can occur. If uplift could cause the components to separate, locking pins must be used and the components secured. To be specific, a "true" surface is as "plumb" or as "level" as the job requires (which, in most cases, is a perfect level of both or either). We will deliver to you the highest quality property and casualty insurance programs and strategic planning consultation services in a manner that is most suitable to achieving your business goals. The scaffold was constructed on a poured concrete floor and had been leveled. Requirements to prevent falls that apply only to these workers are addressed separately below. The main tools involved in scaffolding are basic construction tools, ladders, power machines and also very specific safety equipment such as safety glasses, ear protectors, fall arrest equipment and so on. Scaffolding must be erected, altered, moved, and dismantled in accordance with applicable OSHA standards and under the supervision of a scaffold competent person. The technical storage or access that is used exclusively for anonymous statistical purposes. 3. While sitting or kneeling on a fixed deck plank attached to a fabricated frame scaffold, a worker was pulling a 16-foot long 2x4 off the bucket of an excavator. Where platforms overlap to create a running scaffold, the overlap must occur only over a support and shall not be less than 12 inches unless nailed together. The planking used must be "scaffold grade.". Top rails (manufactured after 1/1/2000) must be 38 - 45 inches above the platform surface. All brace connections shall be made secure. Prepares layout, using rule, framing square, and calipers. Lanyards or connecting devices must be connected to a vertical lifeline (1st choice), a horizontal lifeline (2nd choice), or a structural member of the scaffold (last choice). General Guidelines. The correct procedures for dealing with those hazards. An employee was constructing the third level of a tubular, welded-frame scaffold while standing on the second level. To check a scaffold for being plumb, use a level on two opposite uprights. The hazards of type of scaffold being used. Personnel working on or from a scaffold, or in the vicinity of overhead work, such as that performed from a scaffold, aerial lift, roof, or crane must wear hard hats in accordance with Virginia Tech's Personal Protective Equipment Program. Keep the scaffold level, plumb, and square. In the same vein, a "true" corner would be squared to exactly 90 degrees. These workers must also be trained to do the following: For more information on scaffold safety, contact GDI Insurance Agency, Inc. and visit OSHAs Safety and Health Topics page at www.osha.gov/SLTC/scaffolding/. Plumb and level all scaffolds as the erection proceeds. e. When a supported scaffold reaches a height that is more than four times its minimum base dimension (4:1), it must be restrained by guys, ties, or braces to prevent it from tipping. Be sure scaffold stays plumb and level as . Runners must: Extend over two poles at minimum. [, Uniform riser height, within -inch, for each flight of stairs. You can measure if something is plumb by using a plumb bob or a spirit or laser level. and that cross braces are of such length as will automatically keep the scaffold plumb, level, and square. Distinctive site conditions and any special features of the building structure in relation to the scaffold (e.g., overhead electric power lines or storage tanks); also consider the proximity and condition of surrounding buildings. Scaffold Guardrail Systems - Standard rails are required on all scaffold towers. Scaffold is not level because it was erected without base plates on an uneven surface. When the employee tried to set the third level frame into the pins of the second level, the frame he was trying to position flipped to one side. OSHA 1926.454 (c) states: When an employer has reason to believe . Midrails must be installed at a height approximately midway between the toprail and the platform surface. Faults: Damaged. from the top of the sill, depending on the slope. [, A stair rail consisting of a toprail and a midrail on each side of the stairway. Personal Fall Arrest System. Bracing Connect panels and frames with diagonal, horizontal, or cross braces along or as a combination, in order to laterally secure the vertical members. Ties, guys, bracing and/or outriggers may be needed to assure a safe, stable scaffold assembly. Scaffolding is naturally unstable because it is usually a tall structure with a narrow base. Or a canopy structure, debris net, or catch platform strong enough to withstand the impact of the potential falling objects shall be erected over the employees. [, Ties, guys, braces, or outriggers shall be used to prevent tipping of supported scaffolds bearing eccentric loads, such as cantilevered work platforms. The poles, legs, or uprights of scaffolds must be plumb, and securely and rigidly braced to prevent swaying and displacement. To control the risk of a scaffold falling or collapsing, employers must assure that scaffolds are built within OSHA standards relating to strength and structural integrity. B. Tube and coupler scaffold design must comply with 29 CFR 1926.451.452. [, Guardrail systems must be installed along all open sides and ends of platforms, and must be in place before the scaffold is released for use by employees other than erection/dismantling crews. In addition, there is a lot of information regarding building your own scaffold towers on the Internet. [, Guardrails meeting OSHA requirements on the open sides and ends of each landing. bucks) must be joined together vertically by coupling or stacking pins (or equivalent means). This will determine how many of each component you will need. Where a platform changes direction (ex. Personal fall protection must be required and provided by the employer where the installation and use of such protection is feasible and does not create a greater hazard. The following procedures will cover all scaffolding erected, . Supported scaffold poles, frames, uprights, etc. Move the scaffold into your desired position, and make sure it is level and secure. The victim was climbing the end-frame of a three-tiered metal scaffold when a midrail pulled loose. Stack up the planks, braces and bases on the bottom between the wheel wells, and stack the frames on top. Guardrails May Have Saved Him, Occupational Safety and Health Administration, Outreach Training Program (10- and 30-hour Cards), OSHA Training Institute Education Centers, Electrical Incidents: Lack of Ground-Fault Protection, Severe Storm and Flood Recovery Assistance, Scaffolding : Supported Scaffolds - Frame or Fabricated, In order to assure stability, supported scaffolds must be set on [, Footings must be capable of supporting the loaded scaffold without settling or displacement. If solid sawn wood is used, it must be scaffold grade. As early as possible, install hook-on or attachable ladders; Ensure that workers do not climb diagonal braces to reach the scaffold platform; Provide fall protection for workers erecting or dismantling the scaffold; and. Some people would like their own customized scaffold towers. Toeboards must be capable of withstanding at least 50 pounds applied in a downward or outward direction. Erects scaffolding and ladders for assembling structures above ground level. The scaffold should be plumb, level and square. Therefore, employers are required to provide safe scaffold access. [, Be seated with side-brackets parallel to the frames, and end-brackets at 90 degrees to the frames. the type of scaffold in question. Never load a scaffold beyond its maximum intended load or rated capacity. The maximum extension of the plank cannot be more than 12 inches for planks that are 10 feet long or less. Plumb and brace poles, legs, posts, frames and uprights to prevent swaying and displacement. Fall protection consists of either personal fall-arrest systems or guardrail systems, and must be provided on any scaffold 10 feet or more above a lower level. Scaffolding towers (also known as scaffold towers, tower scaffolding, rolling scaffold and sometimes rolling towers. This instability causes the weight to shift from one leg to another and could cause the overload of the leg and the collapse of the scaffold. Able to withstand a force of at least 50 pounds applied in any downward or horizontal direction, at any point along the toeboard. PLUMB/LEVEL/SQUARE. Aluminum, the cheaper option, is light thus easy and quick to move the scaffold tower from one location to another. Specific requirements are described below. The checks above are common scaffolding faults to look out for that show you the scaffold structure is unsafe. Scaffold tower can be erected in all shapes and sizes. 2. Haul Scaffolding Safely. OSHA has standards that apply specifically to the steps that must be taken to assure a stable scaffold base. Also they can be mobile or stationary. Also, note that the planks are bowing because the bricks are loaded at one point on the platform instead of being evenly distributed. Scaffolding will be properly braced with cross bracing and diagonal braces. When platform units are abutted together to create a long platform, each abutted end must rest on a separate support surface. Plumb and level all scaffolds as the erection proceeds. To accomplish this, the scaffold design must incorporate a realistic . This topic discusses supported scaffolds. Scaffold Frame keeps only high grade steel scaffolding in inventory, but aluminum scaffold is available on request. [. [, Scaffold components manufactured by different manufacturers must not be intermixed, unless they fit together without being forced and the scaffold's structural integrity is maintained. They should be installed along all open sides and at both ends of platforms, except when used as a walkway, the platform is the main working area of the scaffold. [, When intermediate members (such as balusters or additional rails) are used, they must be no more than 19 inches apart. The Scaffold cross braces should never be used as a means of access. A specific access, such as a mounted ladder, must be used. Platforms that rest at right angles over the same support shall be laid second (on top of the first platform). Critical to scaffolding safety are the use of competent persons for the design, erection/dismantling, and maintenance of scaffolds, and trained workers for their use. The jack-nut at the highest ground level should be set 7.5-15 cm (3-6 in.) Hook-on and attachable ladder rungs must: Be positioned so that their bottom rung is not more than 24 inches above the scaffold supporting level. Extreme weather or damage to structural components can also affect a scaffold's stability. Where the platform will not be more than 14 inches from the face of the work (18 inches for plastering and lathing operations), fall protection is not required. Suspension scaffold rigging must at least 6 times the intended load. (True or False) _____ 3. Don't use bricks, blocks, barrels, or other unstable objects to level a scaffold. Review blueprints, work orders, the project schedule and other written requirements to determine where these scaffolds should be used. Basically this is referring to a stand alone structure with platform. rather than a scaffolding set; the tower will be much shorter and easier to tear down and construct, though it will only be suitable for smaller jobs. This is one more reason for always using fall protection. Frames and panels shall be braced by cross, horizontal, or diagonal braces, or combination thereof, which secure vertical members together laterally. Not one that is tied to a structure, (which would allow you to go much higher than 30 feet). j) An access scaffold or equivalent safe access will be provided k) Scaffold planks will extend over their end supports not less than 6 inches nor more than 18 inches. [, All brace connections must be secured to prevent dislodging. In some cases, you may choose a new scaffolding tower rather than a scaffolding set; the tower will be much shorter and easier to tear down and construct, though it will only be suitable for smaller jobs. Scaffold frames (i.e. Call us today 1-888-991-2929! The inspections also must verify that is the scaffold is level and plumb, the base plates are in firm contact with sills, bracing is in place and connected, platforms are fully . Several days later, a crew of seven workers was instructed to replace the scaffold and finish painting the sign. Scaffolding. Scaffolding must be erected on stable foundation. The distance between beare r s and runners shall not exceed manufacturer's re c o m-m e n d a t i o n s . (k) The poles, legs, or uprights of scaffolds must be plumb, and securely and rigidly braced to prevent swaying and displacement. The top edge height of toprails on supported scaffolds must be between 36 inches and 45 inches. Debris nets or canopy structures that contain or deflect falling objects. Scaffolds and scaffold components must be capable of supporting, without failure, their own weight and at least 4 times their maximum intended load. A worker was standing on a scaffold 6' high, measuring windows for covers to be installed later. [, Be positioned so that their bottom step is not more than 24 inches above the scaffold supporting level, [, Have rest platforms at maximum vertical intervals of 12 feet, [, Have a minimum step width of 16 inches, except for mobile scaffold stairway-type ladders, which shall have a minimum step width of 11 inches [, Have slip-resistant treads on all steps and landings. Step 2. [, Be used only to support personnel, unless the scaffold has been designed for other loads by a qualified engineer and built to withstand the tipping forces caused by other loads. Plumb and level all scaffolds as erection proceeds. Employees involved with set up (or near) the scaffold must wear hard hats. (Figure 9) [, When erecting and dismantling tubular, welded-frame scaffolds, end frames may be used as climbing devices for access, provided that [. Standards are vertical pipes that are connected with clamps or couplers to give the structure its height; ledgers are horizontal braces that steady the structure and give it width. For example, if wrapped with mesh, will the scaffold support expected wind loads? Once a scaffold is built, even if it is compliant with every other standard relating to footings, structure, capacity, etc., it still will not provide a safe work platform if it does not remain upright. Do not force frames or braces to fitlevel the scaffold until proper fit can easily be made. The technical storage or access is strictly necessary for the legitimate purpose of enabling the use of a specific service explicitly requested by the subscriber or user, or for the sole purpose of carrying out the transmission of a communication over an electronic communications network.
