Alteration   

All modifications to existing scaffolding shall be carried out in such a way that the stability of the scaffolding is not impaired. Supplementary components shall be added before those which have to be removed are taken away. If standards are to be removed in order to provide access, additional standards shall first be fixed to both sides of the proposed opening so that the total number of standards in the scaffold is never reduced.

Dismantling  



Prior to dismantling a scaffold, the scaffold shall be inspected and a safe procedure for dismantling is established by the Foreman Scaffolder. During dismantling, no component, the removal of which would endanger the scaffold, shall be removed until steps have been taken to compensate for its removal. No items shall be thrown to the ground - lowering by hand only. If dismantling has reached the stage at which a critical member has to be removed, the stability of the scaffold shall be ensured by fixing a similar component in place lower down the scaffold.

5.8 Firm Foundation  All scaffolds shall be erected on a firm level and consolidated base. No excavation should be carried out near to any scaffolding supports.  Base plates shall be used below each standard on surfaces where there is the possibility of standards deforming the surface.  On surfaces which shall be penetrated by base plates which support standards, sole plates of timber shall be used beneath the base plates in order to achieve a greater distribution of the load.  Sole plates shall be at least 35mm thick and 219 mm wide. The sole plate area beneath any one standard shall be at least 1000 cm2 but, if the ground is soft or has been disturbed, this area shall be increased to 1700cm2.

5.9 SPECIAL SCAFFOLDS All scaffolds over 50m high and all sheeted scaffolds over 25m high, together with Hanging, Bridging, Birdcage, Truss-out, Slung, Cantilever Scaffolds, Hoist Towers, Loading Bays and Protection Fans, shall be designed by a competent Civil Engineer in accordance with the requirements of British Standard Specification No. BS 5973 or acceptable equivalent. The Engineer shall provide a written erection and dismantling procedure together with the scaffold drawing and his design calculations. After erection and prior to work commencing upon the scaffold, the Engineer shall inspect the scaffold with the Foreman Scaffolder and the Qualified Inspector who shall approve the scaffold and record his inspection in the "Scaffold Inspection Register" and "tag" the scaffold.

Scaffold towers shall only be erected and used on firm level ground. Static towers shall have metal base plates under the standards, and, unless the foundation is concrete, the load shall be spread by timber sole plates. Wheels, or castors, on mobile towers shall not be less than 125 mm in diameter. Castors shall be fixed into the base of the standards and be fitted with brakes that cannot accidentally be released. Where joints in standards are necessary, they shall be made with sleeve or parallel couplers. Ledgers and transoms, at right angles to the standards, shall commence not more than 150 mm from the bottom to provide a firm base clear of the castors. Lifts shall not exceed 2.7m on static or mobile towers. Bracing shall be fixed to ledgers and transoms with right angle couplers in the form of plan bracing, i.e. diagonally at the base and working platform, and also at alternative lifts; diagonal bracing in zigzag fashion to the full height of the tower on all four sides.

The maximum height to which a static or mobile tower shall be erected is calculated below. The second figure is each ratio represents the smaller of the two base dimensions of the tower.



The maximum height established shall be the height to the working platform, not to the guardrail. The maximum freestanding height for mobile towers shall be 9.6m and, for static towers, 12m. Where the maximum free-standing height or the maximum recommended height to the base ratio requires to be exceeded or the tower is likely to be exposed to appreciable wind loading, the scaffold shall be tied to the structure it is serving, or designed to ensure stability by means of ground anchors, guys or Kent ledge. A ladder for access purposes shall be lashed vertically to one of the narrow sides inside the base area, with the foot resting on an additional transom.

A ladder or trestle shall not be placed on the top platform to extend the height of the tower. Mobile towers shall have their castors turned outwards to provide maximum base dimensions and the brakes locked "on" when the scaffold is in use. Mobile towers shall be moved only by pulling or pushing at the base. No one should be on any part of the scaffold whilst it is being moved. Working platforms shall be clear of persons and materials before towers are moved.

Overhead protection shall be provided for personnel on a scaffold exposed to overhead hazards. Tools, materials, and debris shall not be allowed to accumulate in quantities to cause a hazard. Standard planking shall be scaffold grades or equivalent as recognized by approved grading rules for the type of wood used. Toe boards should be at least 15cm tall. Standard scaffold planks shall extend over there supports at least 15cm and not more than 30cm. All standard platform planking, when overlapped, shall be overlapped a minimum of 30cm and secured from movement with wire or nails. Do not use duplex type nails. Scaffolds shall be provided with a screen, between the toe board and the guardrail extending along the entire opening and consisting of 1cm mesh, when placed where pedestrian traffic must pass underneath. Scaffolds shall not be loaded in excess of the working load for which they are intended. Survey the Project site for hazards before scaffold erection begins for hazards or other hazardous conditions created by other crafts and work environment. Inspect all scaffold components before erecting scaffolds. Never use any scaffolding that is damaged or defective in any way. Defective scaffolding including planks will be returned to the scaffold yard and removed from the project. Do not work on scaffolds if one's physical condition is such that one feels dizzy or unsteady. NOTIFY THE SUPERVISOR OF ACTUAL CONDITION. Scaffolding components shall be used ONLY for the purposes for which it was intended. Before climbing any scaffold, clean mud build-up from work boots to prevent slipping. Scaffolding must not be carried or erected near live overhead cables or equipment due the potential for making accidental contact. Obtain approval from the project electrical and safety representative prior to erecting scaffolds adjacent to electrical power lines. Special precautions shall be taken to protect scaffold elements when using a heat-producing element (e.g. thermocouples for heat-treatments). Retractable lifelines shall be used while ascending or descending access ladders with a fall exposure greater than 15 feet (4.5m). No scaffold may be erected which impedes normal access or can be accidentally struck by moving plant without prior consultation with the Construction Manager so that a safe system of work can be agreed.
