A scaffold can be overloaded by [. Scaffolding means a convenient platform for persons to work at height. Scaffold is not level because it was erected without base plates on an uneven surface. The technical storage or access is required to create user profiles to send advertising, or to track the user on a website or across several websites for similar marketing purposes. Avoid propping the scaffolding frames up on the side of the bed. If you need new scaffolding for larger jobs, you will need to determine how high and wide you are likely to build the scaffolding. 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. All joints must be The scaffold was not secured to wooden footing supports, nor was it tied to the building. One exception is when the scaffold platform is within 14 inches of the face of the work. Is secured to prevent lateral movement. Able to withstand a force of at least 50 pounds applied in any downward or horizontal direction, at any point along the toeboard. (Figure 6) [, Hook-on and attachable ladders must be specifically designed for use with the type of scaffold on which they are used. 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. 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 . Supported scaffold poles, legs . (www.scaffoldframe.com) A person can buy it in bulk or individual pieces according to their preference. Tip: A level may be used frequently during assembly to guarantee that new structural components remain in line. Prepares layout, using rule, framing square, and calipers. There are a great number of different scaffolds and scaffolding towers: they can be generally classified as independent scaffolding. Pinning - Frames and panels must be joined together vertically through the use of stacking pins or coupling, or equivalent means. The drawback to stairways, however, is the amount of space they are likely to take up in the overall structure. Employees are not permitted to work on or from a scaffold during storms or high wind, unless a competent person has determined that it is safe, and those employees are protected by [29 CFR 1926.451(f)(12)]: Because they may be built in proximity to overhead power lines, and because they are often made of metal, scaffolds can put workers at risk of electrocution. Suspension scaffold rigging must at least 6 times the intended load. [, Ends of stair rails and handrails constructed so that they do not constitute a projection hazard. [, Fall protection consists of either personal fall arrest systems or guardrail systems meeting OSHA requirements. This risk can be removed through proper clearance and maintenance. Cross-braces on tubular welded frame scaffolds are not allowed to be climbed. must be plumb and braced to prevent swaying and displacement. Next, select the appropriate-sized scaffold for each job. The legs, poles, frames, and uprights must bear on base plates and mud sills. 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. At Virginia Tech, a fall protection system (i.e. 22.B.12 Scaffolds shall be plumb and level unless engineered and designed to contour as the structure does. 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. [, Have uniform spacing between rungs of a maximum 16 inches. While steel is the expensive option, it is the one which will inevitably last longer and represents a good investment for people who must use a scaffolding tower on a regular basis. [, Nothing that could cause a slip, trip or fall (i.e. [, Guardrails must be surfaced to prevent punctures or lacerations to employees and to prevent snagging of clothing, which may cause employees to lose their balance. A scaffold must be erected "plumb, square, and level," because: - Ans-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. Call us today 1-888-991-2929! Stability and durability are the key components for the scaffold towers to be safe. It's best to have everything as low as possible so parts don't get blown or bounced out. Fasten all couplers and/or connections . The nature of any electrical hazards, fall hazards, and falling object hazards in the work area. You can measure if something is plumb by using a plumb bob or a spirit or laser level. (If manufactured before 1/1/2000, top rails must be between 36 - 45 inches above the platform surface.) He fell to the ground, sustaining a fatal blow to his head. To check a scaffold for being plumb, use a level on two opposite uprights. 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. The height of the scaffold in relation to the minimum base width, wind loads, the use of brackets or cantilevered platforms, and must be plumb and braced to prevent swaying and displacement. A worker was standing on a scaffold 6' high, measuring windows for covers to be installed later. He fell 16 feet to the ground, sustaining facial fractures and other injuries. [, A landing platform at least 18 inches wide by 18 inches long at each level. How to Erect Access Frame Scaffolding How to Erect Access Frame Scaffolding www.worksafebc.com Select . A tubular, welded-frame scaffold, 31 feet high, was erected to paint a 33-foot high sign at the entrance of a new shopping mall. For long (running) scaffolds, guys, ties, and braces shall be installed at each end of the scaffold and at horizontal intervals not to exceed 30 feet. Fasten the levelling jack to the sills with either nails or screws. Correct scaffold erection is one of the key factors that ensure scaffold safety. 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. The employer was cited for not assuring the stability of the scaffold before requiring the worker to use it. Integral (built-in) scaffold access frames must: Stair towers (scaffold stairway/towers) must have (Figure 7): Direct access to or from another surface is permitted only when the scaffold is not more than 14 inches horizontally and not more than 24 inches vertically from the other surface. An access ladder or equivalent safe access must be provided. Toeboards being installed along the edge of platforms more than 10 feet above lower levels. PLUMB/LEVEL/SQUARE. Such a scaffold can be set up on either side of the building, and offers a great level of flexibility.

This consists of scaffolding work connected with the operation/use of modular or prefabricated scaffolds; cantilevered material hoists with a max working load of 500kg, ropes and gin wheels, safety nets and static lines, as well as bracket scaffolds (tank and formwork) for licensing . 1926.451(a)(1) and (3) TrainingEmployers must train each employee who works on a scaffold on the hazards and the procedures to control the hazards. The technical storage or access that is used exclusively for anonymous statistical purposes. [, Ends of rails may not extend beyond their terminal posts, unless they do not constitute a projection hazard to employees. Crawling Board. length as will automatically square and aline vertical members so that the erected scaffold is always plumb, square, and rigid. [, Be specifically designed and constructed for use as ladder rungs. Supported scaffold poles, legs, posts, frames, and uprights shall be plumb (i.e. He fell approximately 12 feet to a concrete dock. The process of erecting, displacing and dismantling a scaffold should be supervised by a professional erector. Others, such as swivel couplers, can be used for a variety of purposes; they can be positioned to allow various angles and crosses among the types of piping. bearer) at an angle other than a right angle, shall be laid first. Learn how your comment data is processed. [, Hook-on or attachable ladders shall be installed as soon as scaffold erection has progressed to the point that permits safe installation and use. Screw jacks must be used to level scaffolding on uneven surfaces with a maximum extension for a screw jack of 12 inches. Platforms may be coated periodically with wood preservatives, fire retardants, and slip-resistant finishes, provided they do not obscure the top or bottom wood surfaces. 3. Personal Fall Arrest System. Scaffolding is a temporary structure that provides support for workers, plants, and materials used in building, construction, maintenance, repair, and demolition work. Install guys, ties and braces according to the manufacturers recommendations. Top rails must be capable of supporting at least 200 pounds applied in a downward or outward direction. Construction and loading must comply with engineered designs and manufacturers requirements. Bracing Connect panels and frames with diagonal, horizontal, or cross braces along or as a combination, in order to laterally secure the vertical members. the side of a building) basically serves as the fall protection system. Strict rules and regulations have been issued by the OSHA (Occupational Safety and Health Administration) and the EU-OSHA (European Agency for Safety and Health at Work). Some people would like their own customized scaffold towers. Do not force frames or braces to fit - level the scaffold until proper fit can easily be made. Reaching 5 foot high all the way up to 30 feet tall. (l) Use a tag line when hoisting materials onto a scaffold. Tube and coupler scaffolds over 125 feet in height must be designed by a registered professional engineer. For lathing and plastering, a gap of 18 inches is permitted. Something that is "plumb" runs perpendicular to the horizonmeaning that when it intersects the horizon, it makes a right (90 degree) angle. [, Stair rails and handrails surfaced to prevent punctures or lacerations to employees, and to prevent snagging of clothing. NOTE: Except where indicated, the same basic scaffold requirements that appear in this module also apply to manually propelled, pump jack, ladder jack, tube and coupler, and pole scaffolds, as well as the specialty scaffolds described in Supported Scaffolds. Tube and coupler scaffold design must comply with 29 CFR 1926.451-.452. 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. In general, a level is the easiest way to achieve the desired right angles. Guys, ties, and braces must be installed at locations where horizontal scaffold components support both inner and outer legs. Personal Fall Arrest System, Guardrail System, or 3/4 inch (1.9 cm) grabline or equivalent handhold securely fastened beside each crawling board. In Asia, bamboo is used as a construction material. [, Employers are required to provide safe access for employees erecting or dismantling supported scaffolds where it is feasible, and where it does not create a greater hazard. Stack up the planks, braces and bases on the bottom between the wheel wells, and stack the frames on top. 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. Basically this is referring to a stand alone structure with platform. Install the deck, which may be an all aluminium platform or with wood deck or scaffold planks. Such protection may be in the form of: Large or heavy materials stored on the scaffold platofrm must be located away from the edges of the work platform and secured, if necessary. The maximum extension for a screw jack is 18 inches high. 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. [, 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.

They may be made of solid material or mesh with openings no greater than 1 inch. The maximum intended load and the load-carrying capacity of the scaffold. Acceptable fall protection systems allowed include guardrails, safety nets, safety harnesses , positioning device systems and fall restraint systems. Fabricated frame scaffolds are the most common type of scaffold because they are versatile, economical, and easy to use. Installed protective coverings to prevent accidental contact with the lines. Cross-bracing is required on both front and back sides of each scaffold buck or frame. One must also consider all the necessary components and hardware needed in order to have the safest most accessible construction work platform. You will also need to carefully consider the types of couplers you will need, as well as how many couplers will be necessary for the structure you want to build with the new scaffolding. Once erected, provide toeboards on all railed sides to prevent falling object hazards. Toeboards must be installed on work platforms where materials or tools will be in use.

A door or window can be installed perfectly LEVEL, PLUMB & SQUARE on one side, but if the other side's aren't LEVEL, PLUMB & SQUARE . Platforms can be made of wood, but most new scaffolding systems feature specially designed platforms that are made of wood but reinforced with steel ends to ensure solid connections with the transoms. For example, if the base width is 5 feet, the first vertical tie will be (5 feet x 4) 20 feet from the ground. [, Ties, guys, braces, or outriggers shall be used to prevent tipping of supported scaffolds bearing eccentric loads, such as cantilevered work platforms. Each section of the framework measured 6'5" high. 6. Also they can be mobile or stationary. Frames and panels shall be braced by cross, horizontal, or diagonal braces, or combination thereof, which secure vertical members together laterally. Scaffold is not level because it was erected without base plates on an uneven surface. They can decide on which material to use and also the desired dimensions. 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 victim was climbing the end-frame of a three-tiered metal scaffold when a midrail pulled loose. Also, note that the planks are bowing because the bricks are loaded at one point on the platform instead of being evenly distributed. [, Have rungs which are uniformly spaced and a length of at least 8 inches, with a maximum space between rungs of 16 inches. 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. The ladder must extend 1 m (3 ft.) above the landing. [, Portable, hook-on, and attachable ladders must be positioned so as not to tip the scaffold. The hazards of type of scaffold being used. 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. 22. [, When moving platforms to the next level, the existing platform must be left undisturbed until the new end frames have been set in place and braced. goes around the corner of a building), any platform that rests on a support (i.e. Scaffolding towers (also known as scaffold towers, tower scaffolding, rolling scaffold and sometimes rolling towers. [, Have rest platforms provided at a maximum of 35 foot vertical intervals. [, 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. Canopy structures made of solid materials. [. Verifies trueness of structure with plumb bob and carpenter's level. Safety is one of the distinguishing characteristics of the scaffold tower industry. That's one of the reasons why we need to keep it inspected - for safety sake! The number one scaffold hazard is worker falls. [, When platforms must overlap because a scaffold changes direction, such as turning a corner, platforms that rest on a bearer at an angle other than a right angle shall be laid first, and platforms that rest at right angles over the same bearer shall be laid second, on top of the first platform. [, When midrails are used, they must be installed at a height approximately midway between the top edge of the guardrail system and the platform surface. Barricades to keep personnel out of a hazardous area. Consider such platforms for added stability and safety. A plumb bob uses gravity to help you align things properly. (Your Answer) 3. Employees must not work on platforms covered with snow, ice or other slippery material. Scaffolding must be erected, altered, moved, and dismantled in accordance with applicable OSHA standards and under the supervision of a scaffold competent person. Platforms and walkways, in general, must be at least 18 inches wide. Scaffolds with a height-to-base width ratio of more than four to one shall be restrained from tipping over by guying, tying, bracing, or equivalent means. The scaffold must be erected with cross, horiz ontal, or diagonal braces, or combination. [, It is dangerous and therefore impermissible for two or more vertical lifelines to be attached to each other, or to the same point of anchorage. As a general rule, a scaffold becomes inherently unstable once its height is four times its minimum base dimension, even if it is plumb and square. This would be in reference to stand alone scaffold towers. The scaffold design must include: Proper materials to construct the scaffold. Personal fall arrest systems used on scaffolds are required when the guardrail system is incomplete or does not provide adequate protection. General Guidelines. [, Not be used as work platforms when rungs are less than 11 inches in length, unless each affected employee uses appropriate fall protection. [, 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. There are two kinds of falling object hazards associated with scaffolds. B. [, Scaffold platforms must be able to support their own weight, plus four times the maximum intended load. [, Have minimum rung length of 11 inches. The correct procedures for dealing with those hazards. Therefore, assessing personnel abilities should be a part of all phases of the scaffolding inspection. Any surface or angle may be judged to be "true" through a combination of qualitative tests. All brace connections must be secured to prevent dislodging. Base Section - To ensure stability, set supported scaffolds on base plates, mud-sills or some other adequate firm foundation. [, OSHA standards specifically forbid climbing cross-braces as a means of access. Extreme weather or damage to structural components can also affect a scaffold's stability. Ladders that are a part of the scaffolding system, such as hook-on and attachable ladders, shall be positioned so that the bottom rung is not more than 24 inches above the supporting level. [. And frames that stick out past the side of the bed can be . 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.
