Check to see if scaffold has been structurally altered in any way that would make it unsafe; and, if so, reconstruct where necessary before commencing with the dismantling procedures. 3. Dismantle scaffold from the top down. Begin by removing all accessories from that section being dismantled at the time. 4. On stacked scaffolds do not remove ties and braces until dismantling has reached the section to which they are attached. 5. Always work within the inside of the scaffolding. 6. When moving up or down the scaffold do NOT climb on ties, braces or un-braced components. Climb over the top of the frame. Do not swing around outside of the frame. 7. Be sure that area below is clear of individuals not involved in the dismantling and is secured against unauthorized access. 8. Lower scaffold components in a safe manner as they are dismantled. Avoid dropping or throwing the components as this could result in injury or damage to the equipment. 9. Use energy absorbing lanyards and full body harness when feasible 4 TOWERINT3 Scaffold Tower Assembly & Operating Instructions SCAFFOLDING SAFETY RULES SERIOUS INJURY OR DEATH MAY RESULT FROM IMPROPER ERECTION OR USE of scaffolding equipment. Erectors and users must be familiar with and follow safe practice and the Safety Rules contained herein. These Safety Rules cover generalized situations only and should not be used to replace any other additional safety and precautionary measures that may be necessary to cover the many usual or unusual conditions encountered during installation or dismantling. The Rules are not intended to conflict with, or supersede the requirements of OSHA or any other governmental regulations, codes and ordinances; the user must refer to and comply with all such specific provisions of law. A. FOLLOW SAFE PRACTICE OF THE SAFETY RULES AND COMPLY WITH OSHA and all other federal, state and local regulations, codes and ordinances pertaining to scaffolding during any use of the equipment. B. THE POTENTIALLY HAZARDOUS NATURE OF SCAFFOLDING ERECTION WORK makes it important that all personnel assigned to this work be instructed in these Safety Rules, safe practices and procedures and be under the supervision of an experienced and knowledgeable person. Assure that these Safety Rules are posted and that all persons erecting and using the scaffold are aware of and follow them. C. REPORT ANY UNSAFE CONDITIONS TO SUPERVISORS. Do not work or allow persons to work on scaffolds when sick or suffering from dizziness, unsteadiness or other physical symptoms which could affect their ability to work safely. D. INSPECT ALL EQUIPMENT BEFORE USING. Never use any equipment which is damaged, defective or deteriorated in any way. E. INSPECT ERECTED SCAFFOLD FREQUENTLY and be sure that they are maintained in safe condition, that scaffold connections have not become loose and that components have not been improperly released or removed. F. MAINTAIN ALL EQUIPMENT IN GOOD REPAIR. Never use corroded or excessively rusted equipment; the strength of such equipment is not known. G. CONSULT YOUR SCAFFOLDING SUPPLIER WHEN IN DOUBT. NEVER TAKE CHANCES. H. ALWAYS READ THESE SAFETY RULES in conjunction with the safety packet. I. ALWAYS SUPPORT SCAFFOLDS FROM A SOUND, STABLE SURFACE and assure that it is adequate to support the intended scaffold loads. Never support scaffolds on unstable, loose objects which could tip, break or become dislodged. J. LIFT AND LOWER COMPONENTS CAREFULLY AND SAFELY; use tag lines when appropriate to the handling method. Never allow excessive quantities of components to be stockpiled on partially complete scaffolds. Stock only sufficient components consistent with the progress of the work. Lower dismantled components as soon as possible. Never drop components deliberately. Scaffold Tower Assembly & Operating Instructions 5 K. TIEING THE SCAFFOLD TO THE STRUCTURE IS OF GREAT IMPORTANCE to the stability and safety of the scaffold. Assure that the structure to which the scaffold is tied or anchored is capable of safely supporting all loads imposed by the scaffold. L. FREE STANDING SCAFFOLDS other than wall scaffolds must be restrained from tipping by guying or other means, recognizing that stability is essential to the safety of the scaffold. M. INSTALL GUARDRAILS, MIDRAILS, AND TOEBOARDS at all openings, open sides and ends of every work platform when recommended or required. N. NEVER USE LADDERS OR MAKESHIFT DEVICES on top of scaffold to increase the height. Never place plank on or stand on guardrails and mid-rails. O. POWER LINES NEAR SCAFFOLDS ARE DANGEROUS. Use extreme caution and consult the power service company to have the lines de-energized, insulated or otherwise rendered safe. Never allow any installation or use of scaffolds until this is done. P. WHEN ANY CANTILEVERS ARE USED, such as brackets, etc., proper care and precautions must be taken to prevent tipping of the scaffold. Q. FOR ROLLING SCAFFOLDS, FOLLOW THESE ADDITIONAL SAFETY RULES: a. Never ride rolling scaffolds. b. Remove all material and equipment from the scaffold before moving. c. Lock caster brakes at all times the scaffold is not being moved. d. Do not attempt to move rolling scaffolds without sufficient help and roll on level surfaces only. Watch out for holes or floor obstructions and for overhead obstructions, including power lines, energized craneways, and other hazards. e. The maximum platform height of a rolling scaffold must not exceed four (4) times the narrowest dimension. Check local state/OSHA Regulations for other height/base limitations such as 3:1 in CA, OH, OR, MT and ME; 3.5:1 in WA. Comply with these regulations by appropriately widening and /or lengthening the scaffold at the lower levels so that the above proportions are not exceeded. If the base dimensions cannot be increased, extreme care must be taken to secure the scaffold from tipping; it must be guyed, or tied to a solid structure and maintained in a stabilized condition at all times so that it cannot tip over while supporting persons, while being moved or while being erected or dismantled. f. Apply pulling or pushing forces at the bottom frames and as close to the scaffold base as possible. Never attempt to move scaffold from on top. g. If rolling scaffolds are used outdoors, care must be taken to assure that they cannot become unstable due to wind or other conditions. R. DO NOT OVERLOAD SCAFFOLD. Refer to and do not exceed the scaffold load capacities. 6 TOWERINT3 Scaffold Tower Assembly & Operating Instructions ASSEMBLE THREE SCAFFOLD UNITS TO BUILD ONE SCAFFOLD TOWER (A) 1-Piece Guard Rail System Set For interior or exterior use.

Inspection of Scaffolding Equipment Prior to Erection Three main areas of inspection are for corrosion, straightness of members and welds. This applies to all components of a scaffolding system. 1. Corrosion- Heavily rusted or eroded scaffolding equipment is a telltale sign of abuse or neglect. 2. Straightness of Members- Mishandling, trucking and storing may cause damage to scaffolding equipment. All scaffolding components should be straight and free from bends, kinks or dents. 3. Welds- Equipment should be checked before use for damage of welds and any piece of equipment showing damaged welds or rewelding beyond the original factory welds should not be used. The factory weld reference pertains to location and quality of welds. While corrosion, straightness of members, and welds are of primary concern other component parts should be checked. 4. Locking devices on frames and braces shall be in good working order, and if not, must be repaired or replaced prior to use. 5. Coupling pins must effectively align the frame or panel legs. 6. Pivoted cross braces must have the center pivot securely in place. 7. Caster Brakes shall be in good working order and if not must be repaired or replaced prior to use. Safe Bearing Loads For Soils Considering that the allowable loads (bearing) on various soils and rock range from less that 1,000 p.s.f. to more than 50,000 p.s.f. care should be exercised in determining the capacity of the soil for every scaffolding job, realizing that weather conditions can turn an otherwise suitable ground condition into a hazardous situation. As an example, dry clay with an allowable bearing capacity of 8,000 p.s.f. could become very plastic after a rainfall and drop to less than 2,000 p.s.f. Care should also be taken not to excessively disturb the soil. If fill is required in areas where scaffolding is used, a qualified engineer should be consulted as to materials and compaction. Foundations The purpose of a good foundation or mud sill is to distribute the scaffolding load over a suitable ground area. The size of the footing or sill is determined be the total load carried over a particular ground area, and by the nature of the soil supporting these sills. The total load should be computed and the sills designed accordingly. When scaffolding from earth fill, the areas should be leveled and the sills spaced in a pattern assuring adequate stability for all scaffolding legs. Erection of Frames The work of erecting the scaffolding should be under the supervision of a person with proper experience and aptitude for securing a safe installation and who is familiar with all Local, State and Federal Regulations concerning scaffolding as well as the SSFI Scaffolding Safety Rules. It shall be the responsibility of the person supervising the erection of the scaffold to see that all components and locking devices are in working order, and no damaged or deteriorated equipment is used in the setup. Should any scaffolding become damaged after the equipment has been erected, Workman shall not be allowed on the same until the damaged items have been repaired or replaced. Advance planning will help the erection of scaffolding to progress smoothly. The equipment should be unloaded as close to the area of use as possible and should be arranged in the order it is to be used in the setup. Adjustment screws should be set to the approximate final adjustment before setting up the scaffolding. Check that all coupling pins are matched with the proper panels. Consult safety rules as recommended by the Institute. After erecting the first tier of scaffold frames, plumb and level (using instruments) all frames so that no matter how high the final scaffolding setup, the additional frames will also be in correct alignment. As erection proceeds, securely tie all scaffolding to the structure at the ends and at least every 30’ horizontally, and at height intervals not to exceed * four (4) times the minimum base dimension. Freestanding scaffold towers must be restrained from tipping by guying or other means. Scaffold frames must be fastened together at coupling pins where there is a possibility of uplift. When scaffolds are to be partially or fully enclosed, specific precautions must be taken to assure frequency adequacy of ties attaching the scaffolding to the building due to increased load conditions resulting from effects of wind and weather. The scaffolding components to which the ties are attached must also be checked for additional loads. When erecting additional lifts, always work from planking within the scaffold structure. Move planking as erection progresses. Planking and Accessories Use only lumber that is properly inspected and graded for use as scaffold plank. Planking shall have at least 12” of overlap and extend 6” beyond center of support or be cleated at both ends to prevent sliding off support. Do not allow unsupported ends of plank to extend beyond supports. Secure plank to scaffolding when necessary. All scaffold accessories shall be used and installed in accordance with the manufacturer’s recommended procedures. Accessories shall not be altered in the field. When installing hanger or clamp supported putlogs (trusses), care should be taken to see that they extend 6” beyond the point of support. Also, make sure that the proper bracing is placed between the putlogs (trusses). When the span between supporting members is more that 12’ additional bracing between the putlogs (trusses) and the supporting member may be required. Do not cantilever or extend putlogs (trusses) as side brackets without thorough consideration for the loads to be applied or transmitted to the scaffold. When clamping putlogs, clamp capacity may control rather than putlog capacity. Consult scaffold manufacturer. All brackets should be seated correctly with side brackets parallel to the frames and the end brackets at 90 degrees to the frame. Brackets shall not be bent or twisted from normal position. Equip all planked or staged areas with proper guard rails and add toeboards when required. Final and Daily Inspection of Erected Scaffolding The following is a list of check points to be covered when making a final and daily inspection of scaffolding prior to use. All points should be carefully checked to insure a safe and accident-free job and be periodically rechecked. 1. Check to see that there is proper support under every leg or every frame on the job. Check also for possible washout due to rain. 2. Check to make certain that all base plates and adjustment screws are in firm contact with their supports. All adjustment nuts should be snug against the legs of the frame. 3. Frames should be checked for plumbness in both directions. 4. If there is a gap between the lower ends of one frame and the upper end of another frame it indicates that one adjustment screw must be adjusted to bring the frames in contact. If this does not help it indicates that frame is out of square and should be replaced. 5. Each leg of the frame should be cross braced to the corresponding leg of the next frame. 6. While checking the cross braces also check the locking devices to assure that they are all in their closed position or that they are all tight. 7. Check to be certain that all planking and accessories are properly installed. 8. Check to make certain all ties are secured between the structure and the scaffolding. 9. Check to be certain all guard rails are in place. 10. If scaffolding is enclosed, check to see that additional precautions have been taken as noted in the “Erection of Frame” section. Recheck periodically ties, clamps, etc., for movement. 11. Insure that safe access to work platforms(s) is provided. Dismantling of Scaffolding The work of dismantling scaffolding should be under the supervision of an individual with proper experience and aptitude. The following should be observed while dismantling. 1. Check to see if scaffolding has been structurally altered in any way which would make it unsafe, and if so reconstruct where necessary before commencing with the dismantling procedure. 2. Dismantle scaffold from the top down. Begin by removing all accessories from that lift being dismantled at the time. 3. Always work from a minimum of two planks placed on the tier of frames below those being removed. Move the planking down as dismantling progresses. 4. Do not remove ties until dismantling has reached the tier to which they are attached. 5. Always stay within the inside of the scaffold. Do not climb on the outside for any reason when dismantling. Do not climb on ties, braces or unbraced frames. 6. Only remove fastening devices from bottom of frames being removed. 7. Lower scaffolding components in a safe manner as they are dismantled. Avoid dropping or throwing the components as this could result in damage to the equipment, or injury to personnel below. Erection of Rolling Towers When erecting rolling scaffolding towers, the following additional items apply. These items are in addition to the application portions of the preceding section. 1. Caster should be of adequate load capacity and size in relation to the height of the tower, the surface over which the tower is to be used and in accordance with all government, state, and local codes, ordinances and regulations. Casters with plain stems shall be attached to the panel or adjustment screw by pins or other suitable means. 2. Do not extend adjusting screws on rolling towers more that 12”. 3. The platform height shall not exceed * four (4) times the smallest base dimension unless guyed or otherwise stabilized. 4. Horizontal diagonal braces should be used near the bottom, top and 20’ intervals measured from the rolling surface. 5. When side brackets are used, consideration should be given to the overturning effect these brackets will have upon the stability of the tower. 6. Cross brace both sides of every lift. 7. Install guardrails. 8. Plank according to the “Plank and Accessories” section. * Exceptions: Three times in California, Ohio, Oregon, Montana, Maine; 3.5 times in Washington. Final Inspection of Rolling Towers The following additional points should be checked when making a final inspection of rolling towers prior to their use. These points are in addition to the applicable times covered under the preceding section entitled. “Erection Of Rolling Towers” 1. Check to see that the platform height does not exceed* four (4) times the smallest base dimension unless the tower is properly guyed or otherwise stabilized. 2. Check to see that, if adjusting screws have been used, they are not extended more than 12”. 3. Check to make sure the caster brakes are in good working condition and are applied when tower is not being moved. 4. Inspect to make sure horizontal diagonal bracing has been placed near the bottom, top, and 20’ intervals measured from the rolling surface. A hook on manufactured platform properly attached to the top frame may be equivalent to the top horizontal diagonal brace. 5. Cross bracing had been installed on both sides of every lift. 6. Check the area in which the tower is to be used to insure there are no obstructions either in, on, or above the floor which will interfere with the proper and safe use of the rolling tower. 7. Check for guardrails. 8. Check to see that all planks and fabricated platforms are properly installed. 9. Insure that safe access to work platforms(s) is provided. Refer to “Scaffolding, Shoring & Forming Institute Scaffolding Safety Rules” before using scaffolding. The procedures outlined in this guide described conventional procedures for erecting and dismantling scaffolding systems. However, equipment and systems differ and, accordingly, reference must always be made to the instructions and procedures of the manufacturer or supplier of the equipment. Since field conditions vary and are beyond the control of the Institute and its members, safe and proper use of this equipment is the responsibility of the user and not the Institute or its members.
