Note: Proprietary temporary edge protection systems such as that illustrated above require a safe work method statement and the scaffolders to undertake training to use the system safely. Note: Follow the below dismantling sequence if you are using erection platforms. 1 Scaffolds are commonly used for working at heights and there is the potential risk for a scaffolder (person working on a scaffold) to fall from an incomplete scaffold during the erection and dismantling of a scaffold. Table 1 applies to all scaffolds that fit within the below design assumptions. Scaffolding work is erecting, altering or dismantling a temporary structure erected to support a platform and from which a person or object could fall more than 4 metres from the platform or the structure. The manufacturer should provide operating instructions. For scaffolds with greater structural capacity or that otherwise do not comply with the design assumptions, a revised version of table 1 may be developed based on an engineering review of the specific scaffold system. Is the bay size 2.4 m x 1.3 m or less (approximately)? Sufficient time should be allowed for the dismantling work to be conducted safely. 2.2 All scaffolds shall be designed by a qualified person. Where you answer ‘no’ to any item, you should ensure that the item is still addressed to meet your legal obligations. Dismantling of metal scaffolds The dismantling work shall be done by trained workmen under the immediate supervision of a competent person. Inspections of scaffolds must be conducted: a. In such instances alternative safe work methods must be developed to provide an equivalent level of safety. secure objects or remove unsecured objects from the scaffold, repeat erection sequence as per previous task, access the scaffold platform from a ladder or stair access – do not climb the standards, ledgers and transoms, do not overload the scaffold bays – progressively remove scaffolding equipment from platforms and stack it neatly on the ground, do not leave loose materials on platforms, do not throw down any materials or scaffolding equipment, remove chain wire mesh and shade cloth while working from a fully planked platform, work with a guardrail in place when removing and passing mesh panels down, work from a fully planked platform below when dismantling hop-up brackets, tie bars and planks, do not allow an unsheeted scaffold to free stand more than 4 m or a sheeted scaffold more than 2 m above the highest tie remaining in place, before lifting a toeboard, ensure the adjacent plank is held in place, access the top platform by stairway or ladder, remove chain wire mesh and shade cloth, or mesh panels, from the level to be dismantled or from the whole scaffold if not required during the dismantling process, working from an erection platform on the fully planked platform, dismantle guardrails, mid-rails, ledgers, transoms and standards from the level above, dismantle the hop-up platform above, if in place, remove not more than three planks (ensure at least two planks remain) to enable the dismantled materials to be passed down to the next level (where they are to be temporarily stacked or removed from the scaffold), if removing dismantled materials progressively down through the scaffold, ensure that the gaps created are not directly below each other and that planks are replaced when a gap is not being used to lower materials, remove ties progressively as the scaffold is dismantled, progressively repeat this procedure until dismantling can be completed from the ground, standing within the scaffold bay and behind the temporary edge protection, install the mid-rail and guardrail for the platform above, if mesh guard is being used, raise the mesh guard to its new location for the 1 m work platform. The scaffold competent person must be present when building, moving or dismantling the scaffold and must inspect it daily. indicates a legal requirement under the work health and safety legislation exists and must be complied with, a person conducting a business or undertaking who under Clause 293 of the WHS Regulation is, or is engaged as, the principal contractor for the construction project, a vertical structural member of the scaffold that transmits a load to a supporting structure, a surface with adequate stiffness and strength to sustain imposed loads from the scaffold, a guardrail and midrail or proprietary system installed to provide fall protection for scaffolders in advance of the placement (or after removal) of the permanent edge protection, a member fixed to the cantilevered end of a pair of hop-up brackets to prevent the brackets from spreading and the planks from becoming dislodged, a scaffold plank or purpose-designed component fixed at the edge of a platform to prevent material from falling off the platform, the face of a building or structure at which the scaffold has been erected to enable work to be carried out at some stage of the project, a platform on a scaffold, positioned at a work location for supporting personnel, equipment and materials, and used to provide a working area. This guide has been developed in consultation with industry and provides practical guidance for those erecting, altering and dismantling scaffolding, and for principal contractors, employers, suppliers of scaffolds and others involved in using prefabricated steel modular scaffolding. Legislative requirements and guidance materials Have joints in the standards been staggered, as far as reasonably practicable? (The sections below provide design criteria for temporary edge protection and erection platforms). Qualified Person-Design scaffolds-Train employees who work on scaffolding to recognizing hazards and understand procedures to control hazards. DISMANTLING OF SCAFFOLDS Refer to Technical Advisory for Scaffolds1 No. False the start of each shift. The purpose of this procedure is to ensure scaffoldingis adequate for the work to be performed and properly erected and dismantled. Scaffolds over _____ feet in height must be designed by a registered professional engineer. Safety harnesses to be worn a all times by scaffolders and fitted with a 1.75m length lanyard and a 55m opening scaffold hook or simil… (f) (7) - Scaffolds shall be erected, moved, dismantled, or altered only under the supervision and direction of a competent person qualified in scaffold erection, moving, dismantling or alteration. erect mesh panels when working from a fully planked platform with edge protection, gaps between adjoining mesh panels and standards must not be greater than 25 mm, measured horizontally, fill any larger gaps between panels with similar material, do not allow any scaffold fitted with mesh panels to free stand more than 2 m above the highest tie remaining in place, erection in high wind areas, eg coastal or cliff edges, standards are manufactured from tube 48.3 mm od x 4 mm wall thickness and minimum steel grade c250 (minimum yield strength), scaffold is erected nominally plumb and standards are free of bends and damage, maximum height to the top working platform is no more than 20 m, bay size is not exceeding 2.4 m x 1.3 m approximately, number of fully planked platform levels is not more than 10, number of hop-up platforms is not more than 10 – hop-up platforms may be capable of supporting one or two planks wide (about 450 mm), live load (duty rating), uniformly distributed over the working platform, does not exceed permissible duty rating as outlined in table 1, working platforms supported by hop-up brackets are not loaded to more than light duty, regardless of the duty rating of the working platform in the adjoining scaffold bay, number of permitted loaded working platforms and platforms supported by hop-up brackets are not greater than those shown in table 1, where specified, scaffold is sheeted with chain-wire mesh and 20 per cent porosity (minimum) shade cloth, the maximum vertical extension of a clad scaffold above the highest tie does not exceed 2 m, with all standards above the tie being full standards without any joints, wind load is imposed by a wind speed not exceeding 60 kph (16 m/s) acting at 90 degrees directly onto the scaffold face – this design assumption does not allow a scaffold to be erected near a cliff edge or any other area where high winds are likely to occur during the time the scaffold is being erected, used or dismantled (this assumption also applies to incomplete scaffolds), every second standard is tied to a supporting structure of adequate strength, at 4 (maximum) vertical intervals, or scaffolds with a fully planked platform above 14 m, additional ties are placed as per figure 6, the foundation or footing has adequate bearing capacity to support the imposed load from the scaffold (refer to Australian Standard AS4576: Guidelines for Scaffolding), read across the table for each variation of permitted number of loaded platforms and hop-up platforms (eg see the bold figures), platforms within the bay must not be loaded to greater duty loading than shown in the table, load on hop-up platforms must not be greater than light duty loading, for technical specifications on scaffold, contact your local manufacturer. Erection, alteration and dismantling of all scaffolding structures (basic or complex) should be done under the direct supervision of a competent person. Workers must keep safe distances between energized lines and conductive material that’s handled on (or is part of) the scaffold. Erection platform area: minimum 500 mm x 600 mm. Your walkways should also be completely free from waste. Is there adequate supervision to ensure that the control measures are monitored for effectiveness and modifications are recommended when appropriate? Injuries and fatalities are all too common when working on scaffolds that are not properly erected or inspected. On scaffolding edge sides, incorporate a built-in mid-rail. Is the maximum height to the top working platform no more than 20 m? Safety Tips | Working on Scaffolds. Duty holders have responsibilities under the Health and Safety at Work Act 2015. For the purpose of this guide, the following definitions apply: a document published by Standards Australia, the first level of transoms and ledgers above the jacks, a platform that is constructed and that is capable of functioning as a working platform, but is temporarily closed to any loading or access, in accordance with table 1, a bracket that is attached to a scaffold to enable a platform to be placed adjacent to a bay of an independent scaffold. Access ladder and toeboards omitted for clarity. If your scaffolding is going to be erected at least 10 feet above ground, guardrails must be installed on all sides that don't face the building. Employees may not climb a ladder with anything in their hands. Scaffolding is defined as the erection, alteration or dismantling of a temporary structure, specifically erected to support platforms. Secondly, any potential scaffolding obstructions such as trees, bushes, wires, or vehicles should be cleared wherever possible. Strong and secure headgear should always be a given when you're working in construction in any capacity, but also consider anti-slip shoes (particularly if rain is forecast) and scaffolding harnesses where necessary. The following checklist can be used by a person in control of preparing for the erection, alteration and dismantling of a scaffold to ensure the important safety features and procedures specified in this guide are in place. Scaffolding work must be undertaken by a person holding the appropriate class of high risk work licence. Are ties staggered, as far as reasonably practicable? Before erecting scaffolding in either a commercial or residential capacity, check if you need to obtain street closure permission and if you need to work during certain hours in order to protect members of the public. A. Scaffolds should be designed, erected, altered and dismantled only by competent people and the work should always be carried out under the direction of a competent supervisor. 1926.451(b)(2) Are guardrails required on all open sides of scaffolding? Fall hazards are the leading cause of construction worker deaths in the UK, so it’s imperative to follow best practice guidelines. Step Person Action All employees who work on a scaffold must be trained by a person qualified to gain adequate knowledge, skills, and abilities (KSAs) to recognize and control and minimize the hazards associated with the type of scaffold used. While steel is the dominant material used in the manufacture of prefabricated modular scaffolding, the concepts and procedures in this guide also apply to prefabricated modular scaffolds manufactured from other materials. a temporary platform that is placed on the scaffold or temporarily constructed as part of the scaffold to assist with the installation (or removal) of the standards, transoms, ledgers, guardrails and mid-rails for the platform above. This is supported from above and is also perfectly acceptable. However, their equipment is often poorly maintained and they are often untrained. There should be a system in place to limit the number of platforms permitted as working platforms, and to limit the respective platform ratings, to prevent the scaffold being overloaded. OSHA 10-Hour … do not allow any sheeted scaffold to free stand more than 2 m above the highest tie remaining in place. Erection, alteration and dismantling of all scaffolding structures (basic or complex) should be done under the direct supervision of a competent person. Toeboards omitted for clarity. 2 … Are site-specific hazards, eg proximity to powerlines – and control measures included in the scaffolding safe work method statement? If you want to stay safe and get the job done properly without hurting yourself, your workers or any unfortunate members of the public, please read on. erection and dismantling of scaffolding and not just for the work to be carried out by their operatives on the completed scaffold. Scaffolding inspection should be conducted by a scaffold competent person who possesses the minimum qualifications prescribed in their country of work. It applies to workers, supervisors, scaffold qualified persons, scaffold custodians, and Facilities. Are fully planked platforms at every 2–3 m apart vertically? Trained workmen must have formal training in, and possess at least 3 years of experience of, bamboo scaffolding work. (e)(9)(i) - The employer shall provide safe means of access for each employee erecting or dismantling a scaffold where the provision of safe access is feasible and does not create a greater hazard. If a ladder is found to be defective on the jobsite, you should: a. A need of scaffolding contractor has come up to work at elevated height. Work health and safety regulations require the control of risk to health and safety. Scaffold planks supported on temporary transoms (suitable for scaffolding platform spacing of up to 2 m). repeat sequentially until the last two planks remain, another scaffolder, working from the fully planked platform below passes the remaining two planks to the scaffolder above, the scaffolder places the planks on the transoms, completing the raised platform, install toeboards (or other systems to prevent objects falling), install ties from a fully planked platform, check with site management that the supporting structure has sufficient strength to withstand the forces imposed by the scaffold when the tie is connected – ie minimum 615 kg push in or pull out per tie, check the structure and material to which the drilled-in anchors are to be applied, to confirm its suitability for the application, install anchors in accordance with the manufacturer’s instructions, erect or move hop-up brackets, tie bars and planks from the fully planked platform below, erect stairways and ladders progressively from the base of the scaffold, ensure that the top of any ladder extends not less than 900 mm above the highest platform served by the ladder - otherwise provide a suitable handhold to this height, ensure that suitable edge protection is fitted at the opening in each platform served by the ladder within the scaffold bay. Check if any updates or additions to the Australian Standards have been made to: Catalogue No. The concepts within this guide differ from traditional scaffold erection methods, which are no longer considered acceptable. If it's not braced against a building, your scaffolding will more than likely be a wobbly mess that could easily become dislodged. Competence of a worker can be assessed under CISRS or PASMA but there are exceptions when an individual has undergone sufficient training. For scaffolds with greater structural capacity than given by the design limitations in appendix A, the supplier may provide a revised version of table 1 based on an engineering review of their specific scaffold. the scaffolder should be supported on a fully planked platform when installing the platform immediately above, except for platform spacings above 2 m where another purpose-made erection platform may be required for platform installation, the fully planked platforms should be nominally 2 m apart, vertically, and remain in place until the scaffold is dismantled, the first platform can be up to 3 m above the ground or supporting surface, except for the access bay, safe access must be provided up to the first platform and between platforms on the scaffold, risks from overhead power lines must be assessed and controlled – see the, prevent unauthorised access to scaffold area, one scaffolder holds standards, while another places transoms and ledgers, erect transoms and ledgers for the first lift, erect planks from below for the first lift, install access stairway or ladder to platform for the first lift, if access is by stairway, ensure the stair access bay is erected with the run of the scaffold, install edge protection comprising guardrail, mid-rail and toeboard or mesh panels to first lift, place an erection platform on the scaffold – see figures 1, 2, 3 and 4 for erection platform options, working from the erection platform, erect standards (where the standard joint is 1 to 1.5 m above the erection platform level), mid-rails and guardrails for the lift above, standing on the working platform (or an erection platform for lifts of 2.5 to 3 m), place planks within the transoms to form the above working platform, install ladder or stairway access to working platform above, install toeboards (or other systems to prevent objects falling), install temporary edge protection for platform above – see figure 5, install transoms and ledgers for platform above. Tools and materials may be carried on their person or hoisted up/down by rope or other devices. Key points. fix containment sheeting securely to the scaffold at every platform level and at the top and bottom of the scaffold. Maintain a minimum of 10 feet between the scaffold and any electrical hazard. Ontario law requires that: all platforms on a scaffold must be at least 18 inches wide It covers selecting, erecting, and dismantling all types of scaffolds. 125. For safe completion of the work, consider the following: Erection platforms should comply with the criteria given below. OSHA Scaffold Inspection Requirements . You'd be surprised how many scaffolding rogue traders are operating in the UK and how professional they can appear at first glance. Figure 3: Diagrammatic illustration of an erection platform option for a five-plank-wide scaffold. 2.3 Competent Person Inspectors and Erectors shall be trained in the type of scaffold being inspected or erected. Safety regulations dictate that anyone working from height on scaffolding is required to be properly trained. The permitted scaffold configurations are intended to assist those erecting less complex scaffolds to do so without having the structural capacity of their scaffolds checked by an engineer. If it's overly wet or icy, it's recommended that all workers steer clear of any scaffolding unless absolutely necessary. 3.2. Note: Scaffold is shown against an existing building, so guardrails only needed on external face. There are risks associated with scaffolders falling through and from the scaffold. There should also be room enough to provide truck access to transport the scaffolding parts to a loading area. The most recent report conducted by the Canadian Centre for Occupational Health and Safety (CCOHS), showed that 251,508 Canadian’s accepted claims for lost time due to work-related injury or disease in just one year. Are the number of fully planked platforms and hop-up platforms, and their associated duty ratings, in accordance with table 1? Fully decked scaffolds over 20 m in height may exceed the design strength of the system and the design should be verified by the manufacturer, supplier or an engineer competent in scaffold design. Finally, when the job is done and you're ready to pack up and go home, make sure you dismantle scaffolding section by section in the same order it was erected. dismantling of a temporary structure, specifically erected to support platforms. This means that all of the parts are secure, in good condition, and regularly maintained. Does the site-specific induction include the names of all persons responsible for implementing control measures in relation to scaffolding? Principal contractors must clearly identify in their written WHS management plan those responsible for implementing the control measures. For standards supporting sheeting, are all the joints below the top working platform? Be aware of your fellow workers at all times. Are there 10 or less available hop-up brackets capable of supporting platforms? Clear a nearby space to set the dismantled pieces of scaffolding down. Depending on the job, your scaffolding is undoubtedly going to be put under some heavy loads with workers and equipment. And only a person holding the appropriate scaffolding safety licenses and permits should undertake it. Printed on Tuesday, 20 October 2015. The scaffold to be dismantled should be checked for its strength & stability beforehand. 3.1. Figure 2: Diagrammatic illustration of erection and dismantling using various erection platform options – two-man operation. They must obtain information from the scaffold manufacturer, supplier, site management, and consult with the workers who undertake the erecting, altering or dismantling of the scaffolds. Permitted number of loaded hop- up platforms, Table 1: Permitted number of loaded platforms and hop-up bracket platforms, Figure 6: Diagrammatic illustration of a typical tie pattern. These guidelines offer advice for keeping workers safe when erecting, dismantling and working on scaffolding. 6. control measures for working platforms 10 7. erecting, altering or dismantling 11 7.1 generic work sequence – scaffold erecting and dismantling 11 7.2 erection platform options 16 appendix a – checklist 20 appendix b – further information 22 Use the ladder to get through your task and be sure to replace it later b. Platform area: minimum 350 mm wide x 300 mm deep, including the ladder rung if it is at the same level as the platform. However, ‘Appendix A – Scaffold design limitations’ only applies to prefabricated steel modular scaffolding. Contact the Customer Service Centre on 13 12 42 or visit saiglobal.com/shop. By reviewing and completing this checklist with all ‘yes’ answers, you will be well on your way to achieving your legal obligations. Dismantling Scaffolds and A bout 2.3 million peopleinthe construction in-dustry, or 65 percent of the total number, work on scaffolds frequently. Note: If in doubt, get expert advice. Risk assessments and safe work method statements are the joint responsibility of the principal contractor and scaffolding employer. SCAFFOLD ERECTION AND DISMANTLING This course is meant for anyone who is involved in practical Hands-On erection and dismantling of several types of basic frame, tube & coupler, and “system” scaffolds.
