Putlog scaffolds are erected as the external wall is constructed. In such works the blade may also be placed vertically. Close boarding, netting and sheeting must be used to prevent objects from falling onto anyone below. Standards: The vertical posts (also called uprights). Transoms: Putlogs whose both ends are supported on ledgers in double scaffolding. The use of shore or lean-to scaffolds is prohibited. When laying bricks, the scaffold platform should be at least five boards wide (1150mm). Stair tower (Scaffold stairway/tower)--a tower comprised of scaffold components and which contains internal stairway units and rest platforms. Braces: The bracing system. Subsequently the structure must be checked on a regular basis to ensure it remains safe throughout its use. Decks are also referred as planks and they are available in aluminium, aluminium frame with plywood board and hot-dip galvanised steel. Thawing soil can become water-soaked and lose its ability to bear weight. Audience. Any damaged component must be removed, repaired or replaced. For small scaffolds, bracing may not be required across the width of the scaffold since the frame is very rigid. Any damaged component must be removed, repaired or replaced. To render additional support for the boards, intermediate transoms are placed between the main transoms. The use of shore or lean-to scaffolds is prohibited. Toe boards must be used at the end of the scaffolding to ensure that materials and tools do not fall off the scaffold. * Patented scaffolding. WAC 296-874-40002: Supported scaffolds and scaffold components must meet strength requirements: Make sure each supported scaffold and scaffold component can support, without failure, the total of its own weight plus at least 4 times the maximum intended load applied or transmitted to it. Supported scaffolding – as its name suggests, this type consists of one or more wood or metal platforms that are supported by poles, outriggers, … When using hop-up brackets, care must be taken not to overload the scaffold. At one time, bricklaying gangs would have a labourer who could also erect the scaffold as the brickwork progressed. Supported scaffold user training and refresher training program provides a basic explanation of supported scaffolds and supported scaffold components. Tower scaffold 228. Plan bracing and ledger bracing should be used where specified. Lateral bracing is also applied across the ledgers. When scaffolding is positioned in areas accessed by pedestrians it is necessary to use high visibility warning tape and lighting. Rest platforms must be installed every 35 vertical feet. The blade end of the putlog is usually placed horizontally and inserted fully into the brickwork joint, ensuring a full bearing is achieved. The scaffold lifts must progress at the same speed as the masonry work.

Course Description: Supported scaffold user training and refresher training program provides a basic explanation of supported scaffolds and supported scaffold components.The course will introduce the elements of supported scaffold safety and common supported scaffolds hazards while placing an emphasis on hazard reduction and prevention which includes fall protection, scaffold … It is also known as putlog scaffolding.. Prerequisites Per federal regulation 29 CFR 1926.451, each scaffold and scaffold component must support its own weight and a minimum of four times its maximum intended load. SCAFFOLDING. A competent person must inspect the whole of the scaffolding and associated temporary supports, including the tying in and sections that are welded, bolted and fabricated off site, prior to use. These towers are used to provide access to scaffold platforms and other elevated points such as floors and roofs. Supported Scaffolding Tube and Coupler. Temporary support required to provide a safe and convenient working surface is known as scaffold or scaffolding. Where loads are increased or hop-ups are used, additional bracing is required. This 4X minimum safety factor for all supported scaffold systems and components was established by the American National Standards Institute’s Scaffolding Safety Requirements (ANSI/ASSE A10.8-2011) and is intended to account for, among other items, the scaffold’s age, environmental exposure, and extent of use (or abuse) over its lifetime. It can either run across the face of the scaffold to its full height at an angle of 45° or run in a zig-zag fashion to its full height. Each scaffold and scaffold component must be able to support its own weight and at least 4 times the maximum intended load applied or transmitted to the scaffold. Lagging and padding can be placed around the standards to reduce the risk of injury from accidental impact with the scaffold. Don’t load the scaffold with more weight than it can safely handle. Every type of scaffold has its own advantages and limitations. The scaffolding uses the external wall as part of the support system . All components that are made from metal can be painted but items that are wooden should never be painted as this could hide defects. Each proprietary system varies with manufacturer and system, and the manufacturer’s instructions must be carefully followed to ensure that the scaffold is erected safely. Supported scaffolds with a height-to-base ratio of 4:1 must be tied off or restrained by guying or bracing to eliminate any tipping. On supported scaffolds, working platforms/decks must be planked close to the Each scaffold and scaffold component must support without failure its own weight and at least four times the maximum intended load applied or transmitted to it. The height to base ratio for a supported scaffold must be 4:1 (state plans may vary). In general, a scaffold must be able to support its own weight, plus four times the maximum intended load. Don’t load the scaffold … Let’s take a look at the basic components that are used in scaffolding. 1.3.1. 6. These can be used between the standards or can be used between the internal standard and wall, providing a platform that is closer to the area of work and not reducing the width of the standard platform. The bracing prevents distortion to the rectangular grids. SCAFFOLDING CLAMP LOAD CAPACITY. Supported scaffold--one or more platforms supported by outrigger beams, brackets, poles, The standards often come with spigot ends, which allow the next standard to be located over the locating spigot very quickly.

Safe access must be provided for all scaffold platforms that are more than 2 feet above or below the point of access. Use. Each putlog has one flat end that rests on the bed or perpendicular joints in the brick or blockwork. Features and Benefits. The scaffold and its components should also be checked by a competent person and properly tagged before the start of the shift to ensure its integrity and safety. Every supported scaffold and its components must support, without failure, its own weight and at least four times the intended load . The intended load is the sum of the weights of all personnel, tools and materials you will place on the scaffold. Single scaffolding is constructed parallel to the wall at a distance of about 1.2 m and generally consists of a single framework of standards, putlogs and ledgers etc. Major transoms are positioned next to the standards; they support the standards that are in place and give support for the boards. Gear for suspension of scaffold 229. 1910.28(a)(5) Scaffolds and other devices mentioned or described in this section shallbe maintained in safe condition.

The Aluminum mobile scaffold access tower system is set on castors or wheels to make it easy to move, and is normally used for tasks such as plastering, changing light bulbs, painting and any other overhead work. A scaffold and its components must not be loaded beyond their capacity. * Steel scaffolding. Despite the … There are eight types of suspended scaffolds including catenary, float, multi level, Botswain’s Chair, and swing scaffold which is … If the scaffolding is assembled along an external wall, adjustable leveling jacks nailed on beams are advised. Scaffolds more than 10 m height should be secured for stability at first utilising the fixed structure and for every 8 m height should be provided. In the western world they are now made of metal.. Install scaffold with jackscrews (adjusting screws). Types of Scaffolding: * Single scaffolding. Components, such as ledgers and transoms, are designed so that they can be interchangeable. Training Requirements for 4 Hour Supported Scaffold User & Refresher Course. The intended load is the sum of the weights of all personnel, tools and materials that will be placed on the scaffold. Bracing will be fixed to extended transoms with right angle couplers or to standards with swivel couplers. BOCW ACT 1996 224. When materials are loaded onto the platform, the clear passage for workers should be at least 430mm. While the system uses less scaffolding and is less expensive than independent scaffolding, it is essential that the erection of the scaffold is coordinated with the sequencing of brickwork. 5. 2. Supported scaffold user training online and refresher training program provides a basic explanation of supported scaffolds and supported scaffold components. Do not load scaffolds or scaffold components in excess of their maximum intended loads or rated capacities, whichever is less. Each employer’s safety management system will be different. LEDGER: “A lengthwise horizontal scaffold tube that extends from standard to standard, that supports the transoms and that forms a tie between the standards”. To render additional support for the boards, intermediate transoms are placed between the main transoms. The use of shore or lean-to scaffolds is prohibited. Toe boards are obtainable in aluminium, steel or wood. Any damaged component must be removed, repaired or replaced. They allow for minor adjustments to help keep scaffold plumb and level.
