Toeboards must be installed on work platforms where materials or tools will be in use. Employers must provide fall protection for each employee on a scaffold more than 10 feet (3.1 meters) above a lower level. 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. By far, the most forgotten term of a door installation. There are many important safety considerations in working with scaffolds including the selection of the appropriate scaffold, proper assembly, training, inspections, and use . 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. 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. Some people would like their own customized scaffold towers. Hardware should be included to fasten the planks into place. The amount of time needed to erect and dismantle the scaffold. Canopy structures made of solid materials. Therefore, assessing personnel abilities should be a part of all phases of the scaffolding inspection. 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). 1. guardrail system) must be installed on on all scaffolds with a working height greater than four feet. The entire platform is attached to the fork. Secure scaffolds to the structure during erection and dismantling. You can measure if something is plumb by using a plumb bob or a spirit or laser level. This risk can be removed through proper clearance and maintenance. Tip: One way to ensure a stable foundation, when a sill is used, is to secure it to the baseplate (Figure 2). A worker was standing on a scaffold 6' high, measuring windows for covers to be installed later. Cross-bracing is required on both front and back sides of each scaffold buck or frame. Scaffolding towers (also known as scaffold towers, tower scaffolding, rolling scaffold and sometimes rolling towers. Install guys, ties and braces according to the manufacturers recommendations. 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. The main components are scaffolding tubes, scaffold clamps, and base plates. 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.

Plumb and level all scaffolds as the erection proceeds. Top rails must be capable of supporting at least 200 pounds applied in a downward or outward direction. 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. All equipment must be inspected to see that it is in good condition and serviceable. (k) The poles, legs, or uprights of scaffolds must be plumb, and securely and rigidly braced to prevent swaying and displacement. Uplift is the separation of a frame from the frame below it. Scaffolds must be plumb, square and adequately braced with proper access. Employees involved with set up (or near) the scaffold must wear hard hats. 2. Do not force frames or braces to fit - level the scaffold until proper fit can easily be made. Support scaffold footings must be level and capable of supporting the loaded scaffold. from the top of the sill, depending on the slope. Scaffolding is naturally unstable because it is usually a tall structure with a narrow base. Proper access must be provided to access the work platform of the scaffold. tools, scrap material, chemicals, snow, ice, etc.) (. The hazards of type of scaffold being used.

Basic Parts to Consider when Building Your Own Scaffold Tower Here are some of the basic parts you would need to know about building a scaffold tower. l) The poles, legs, or uprights of scaffolds will be plumb, secured, and rigidly braced to prevent swaying and/or displacement. To check a scaffold for being plumb, use a level on two opposite uprights. (Figure 4) [, Scaffolds shall be altered only under the supervision and direction of a competent person. the type of scaffold in question. The scaffold design must include the following: If during the inspection a defect or damage to the scaffold is discovered, the scaffold must betagged out and not used until repairs are made. 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. (For mobile scaffolds, the maximum height of the screw jack is 12 inches.). 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. Greater variations in riser height are allowed for the top and bottom steps of the entire system (not for each flight of stairs). For lathing and plastering, a gap of 18 inches is permitted. [, 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. We need to follow scaffolding safety procedures. Fasten all couplers and/or connections . Frames and panels shall be braced by cross, horizontal, or diagonal braces, or combination thereof, which secure vertical members together laterally. Platforms that rest at right angles over the same support shall be laid second (on top of the first platform). Fasten the screw jack to the sills with either nails or screws. How to use a plumb bob. 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. Chicken Ladder. (, Midrails, screens, mesh, intermediate vertical members, solid panels, etc., must be able to withstand a force of at least 150 pounds applied in any downward or horizontal direction, at any point along the midrail or other member. [, Do not load the scaffold or any component parts beyond their maximum capacity (their own weight and 4:1 the maximum intended load). Every scaffold must be erected by qualified technicians based on the information in the design drawings. The face of the work (ex. 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. Barricades to keep personnel out of a hazardous area. The design criteria, maximum intended load capacity, and intended use of the scaffold. [, Each employee on a scaffold more than 10 feet above a lower level must be protected from falling to that lower level. Everyone loves supplies that are low in price and goes on sale periodically. 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 maximum intended load and the load-carrying capacity of the scaffold. When the other end of the 2x4 slipped off the bucket, the employee did not let go of his end, and was pulled off the deck. Scaffolds must be fully planked or decked whenever possible. In addition, the scaffold and its components must support, without failure, its own weight and at least four times its maximum intended load. This is one more reason for always using fall protection.

The drawback to stairways, however, is the amount of space they are likely to take up in the overall structure. If solid sawn wood is used, it must be scaffold grade. Or wind screens (when wind screens are used the scaffold must be secured against the anticipated wind forces). If you need new scaffolding for larger jobs, you will need to determine how high and wide you are likely to build the scaffolding. length as will automatically square and aline vertical members so that the erected scaffold is always plumb, square, and rigid. Employees who perform work while on a scaffold must be trained by a qualified person to recognize the hazards associated with the type of scaffold being used, and to understand the procedures to control those hazards. Do not use makeshift methods to increase the working height of the scaffold platform, such as with ladders, buckets or blocks. Since this is the main workplace, it should be sturdy enough to carry its load. Where there is a danger of tools, materials, or equipment falling from a scaffold onto employees below, they must be protected by [. 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. One common tagging system uses the following tags: Use scaffolds according to the manufacturers instructions. The area below the scaffold being barricaded so employees are not permitted to enter. Plumb and level scaffold. Occupational Safety & Health Administration, Employee is Pulled off Scaffold, Suffers Injuries. . The competent person should use this checklist for daily inspections of the scaffold. To counteract this, the scaffold must be braced or tied off to a stable structure such as a structural steel. One must also consider all the necessary components and hardware needed in order to have the safest most accessible construction work platform. 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. Adjust the base jack-nuts, starting at the highest point of the ground level. Medium-duty scaffolds can support 50 pounds per square foot. Crossbracing is required on both front and back sides of each scaffold buck or frame. [, 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. [, Be seated with side-brackets parallel to the frames, and end-brackets at 90 degrees to the frames. [, 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. Midrails must be installed at a height approximately midway between the toprail and the platform surface. As one of the fastest growing agencies in California, GDI Insurance Agency, Inc. is able to provide its clients with the latest and greatest of what the insurance industry has to offer and much, much more. Supported scaffold poles, frames and uprights must be plumb and braced to prevent any displacement caused by swaying. Due to their strength, these scaffolds are frequently used where heavy loads need to be carried, or where multiple platforms must reach several stories high. Such retraining is required in at least the following situations [. Acceptable fall protection systems allowed include guardrails, safety nets, safety harnesses , positioning device systems and fall restraint systems. 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. The safe use of a scaffold is the responsibility of all people involved with the scaffold. When toeboards are used for falling object protection, they must be [. 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.

The base and mud sill must provide a solid surface for the feet to sit upon so that the scaffold doesn't sink, move, settle, or shift. Specific requirements are described below. Check the level again and plumb if necessary. is allowed to accumulate on the platform. Tip: A scaffold can be overloaded by removing the braces, which causes the weight on the scaffold to be distributed to fewer structural members. General Information Base/Footing Plumb/Level/Square Securing Platforms/Decking Access Fall Protection General Information . [, 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. The technical storage or access that is used exclusively for anonymous statistical purposes. Therefore, employers are required to provide safe scaffold access. For most activities, there must be no more than a 14-inch gap between the scaffold platform and the structure being worked on. A scaffold must be erected "plumb, square, and level," because: Answer: 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. The scaffold was constructed on a poured concrete floor and had been leveled. [, Guys, ties, and braces must be installed according to the scaffold manufacturer's recommendations or at the closest horizontal member to the 4:1 height ratio and be repeated every 20 vertical feet for narrow scaffolds (3 feet or less in width), and every 26 vertical feet for scaffolds greater than 3 feet in width.
