Employees must not work on platforms covered with snow, ice or other slippery material. 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. Uplift is the separation of a frame from the frame below it.

If using wooden planks, they must extend beyond the supporting Employers are required to provide fall protection for employees erecting or dismantling supported scaffolds where it is feasible, and where installing and using it does not create a greater hazard. An employee was constructing the third level of a tubular, welded-frame scaffold while standing on the second level. Unstable objects, such as bricks, cinder blocks, buckets, scrap lumber, etc., shall not be used to support or level scaffolds. They are erected in a manner that creates a usable ladder and provides good hand hold and foot space. 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. Scaffold tower can be erected in all shapes and sizes. 1. Supported scaffold poles, frames, uprights, etc. Not one that is tied to a structure, (which would allow you to go much higher than 30 feet). [, Frames and panels must be connected by cross, horizontal, or diagonal braces, alone or in combination, which secure vertical members together laterally. [, 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.

[, 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. perfectly vertical) and braced to prevent swaying and displacement. At Virginia Tech, a fall protection system (i.e. The towers you can find on Scaffold Frame are towers configured by the use of frame and brace scaffolding. A tube and coupler scaffold has a platform(s) supported by tubing, and is erected with coupling devices connecting uprights, braces, bearers and runners. Do not force frames or braces to fitlevel the scaffold until proper fit can easily be made. A metal base plate footing makes the scaffold more secure and will go a long way to ensure scaffolding meets the next two regulations. 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 . The forklift is not moved horizontally while the platform is occupied. 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 . Plumb and level all scaffolds as the erection proceeds. TRUE represents being SQUARE on both the LEVEL & PLUMB axis at the same time on all sides of the unit being installed. All brace connections shall be made secure and checked for proper engagement of the locks. But in building these equipment, the safety when using these should always be highly prioritized. Faults: Damaged. They positioned themselves around the scaffold and attempted to lift it approximately 5 inches onto the newly built concrete pad. 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.

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. Each frame or panel shall be braced by horizontal bracing, cross bracing, diagonal bracing or any combination thereof for securing vertical members together laterally. 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. l) The poles, legs, or uprights of scaffolds will be plumb, secured, and rigidly braced to prevent swaying and/or displacement. The proper use of the scaffold, and the proper handling of materials on the scaffold. Make sure that a competent person inspects the scaffold before each work shift. 1. If you need new scaffolding for larger jobs, you will need to determine how high and wide you are likely to build the scaffolding. 2. Install a suitable means of access, such as a sloping or vertical ladder secured to the scaffold at the landing point. 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 erected scaffold must support its own weight and at least four times the maximum intended load. The scaffold was constructed on a poured concrete floor and had been leveled. [, Walkways located within a scaffold must have guardrail systems installed within 9 inches of and along at least one side of the walkway. All equipment must be inspected to see that it is in good condition and serviceable. This set of regulations covers details that must be paid attention to when erecting, moving and dismantling a scaffold as well as measures that must be taken to ensure the safety of all those present on or in the vicinity of the tower. [, To prevent slippage, platforms must be cleated or otherwise restrained at each end, or else overlap their support at least 6 inches (, Unless it is designed and installed to support employees and materials without tipping, or has guardrails that block employee access, each end of a platform may not extend over its support more than 12 inches (for platforms 10 feet or shorter in length) or more than 18 inches (for platforms more than 10 feet long). The space between planks cannot exceed 1 inch, except where necessary for obstructions.

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. by Grant Davis | Construction, Insurance, Safety Tips | 0 comments. Since it is an elevated platform, the stability decreases as the height increases. (1) Scaffolds shall be properly braced by diagonal braces for securing vertical members together laterally, and the cross braces shall be of such length as will automatically square and align vertical members so that the erected scaffold is always plumb, square, and rigid. 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. In such cases, the platforms must be as wide as feasible, and fall protection must be provided. Requirements to prevent falls that apply only to these workers are addressed separately below. The space between the last plank and the uprights cannot exceed 9 1/2 inches. And also, there are lots of sites that sell scaffolding spare parts. Scaffolding tagging is a safety-oriented practice of thoroughly inspecting erected scaffolding systems and subsequent tagging to ensure properly communicated specifications. [, 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. [, Scaffold platforms must be able to support their own weight, plus four times the maximum intended load. [, Do not load the scaffold or any component parts beyond their maximum capacity (their own weight and 4:1 the maximum intended load). OSHA has standards that apply specifically to the steps that must be taken to assure a stable scaffold base. Tip: One way to ensure a stable foundation, when a sill is used, is to secure it to the baseplate (Figure 2). There are two kinds of falling object hazards associated with scaffolds. Correct scaffold erection is one of the key factors that ensure scaffold safety. 2. Scaffold Frame keeps only high grade steel scaffolding in inventory, but aluminum scaffold is available on request.
