ALUMINUM I-BEAM Its strength and lightweight properties provide an optimal working combination. Aluminum minimizes the number of total horizontal and vertical members required on the job, compared to wood. Since it is lightweight compared to steel, the contractor realizes labor productivity through ease of use. The beam contains a 2" x 2" plastic nailer strip which is formulated to provide nail gripping properties comparable to wood, and will not become soft in hot weather, nor brittle, nor crack in extreme cold. Plastic nailers are much more durable than wood and will withstand repeated use as plastic is apt to self-heal upon fastener removal. The beam has a T-Head Bolt slot in its base for fastening stringers, strongbacks or I-Beams with the easy-to-use self-locking A-Clamp. CODE SIZES WEIGHT AB--- From 1 21 4 lbs /ft A- CLAMP ASSEMBLY A-Clamps secure beam to beam, beam to stringer, or stringer to stringer.

CODE OF SAFE PRACTICES FOR FRAME SCAFFOLDS, SYSTEM SCAFFOLDS, TUBE AND CLAMP SCAFFOLDS & ROLLING SCAFFOLDS DEVELOPED FOR INDUSTRY BY SCAFFOLDING, SHORING & FORMING INSTITUTE (SSFI) and SCAFFOLD INDUSTRY ASSOCIATION, INC. (SIA) It shall be the responsibility of all users to read and comply with the following common sense guidelines which are designed to promote safety in the erecting, dismantling and use of Scaffolds. These guidelines do not purport to be all inclusive nor to supplant or replace other additional safety and precautionary measures to cover usual or unusual conditions. If these guidelines in any way conflict with any state, local, provincial, federal or other government statute or regulation, said statute or regulation shall supersede these guidelines and it shall be the responsibility of each user to comply wherewith. I. GENERAL GUIDELINES A. POST THESE SCAFFOLDING SAFETY GUIDELINES in a conspicuous place and be sure that all persons who erect, dismantle, or use scaffolding are aware of them, and also use them in tool box safety meetings. B. FOLLOW ALL STATE, LOCAL AND FEDERAL CODES, ORDINANCES AND REGULATIONS pertaining to scaffolding. C. SURVEY THE JOB SITE. A survey shall be made of the job site by a competent person for hazards, such as untamped earth fills, ditches, debris, high tension wires, unguarded openings, and other hazardous conditions created by other trades. These conditions should be corrected or avoided as noted in the following sections. D. INSPECT ALL EQUIPMENT BEFORE USING. Never use any equipment that is damaged or defective in any way. Mark it or tag it as defective. Remove it from the job site. E. SCAFFOLDS MUST BE ERECTED IN ACCORDANCE WITH DESIGN AND/OR MANUFACTURERS RECOMMENDATIONS. F. DO NOT ERECT, DISMANTLE OR ALTER A SCAFFOLD unless under the supervision of a competent person. G. DO NOT ABUSE OR MISUSE THE SCAFFOLD EQUIPMENT. H. ERECTED SCAFFOLDS SHOULD BE CONTINUALLY INSPECTED by users to be sure that they are maintained in safe condition. Report any unsafe condition to your supervisor. I. NEVER TAKE CHANCES! IF IN DOUBT REGARDING THE SAFETY OR USE OF THE SCAFFOLD, CONSULT YOUR SCAFFOLD SUPPLIER. J. NEVER USE EQUIPMENT FOR PURPOSES OR IN WAYS FOR WHICH IT WAS NOT INTENDED. K. DO NOT WORK ON SCAFFOLDS if your physical condition is such that you feel dizzy or unsteady in any way. L. DO NOT WORK UNDER THE INFLUENCE of alcohol or illegal drugs. II. GUIDELINES FOR ERECTION AND USE OF SCAFFOLDS A. SCAFFOLD BASE MUST BE SET ON BASE PLATES AND AN ADEQUATE SILL OR PAD to prevent slipping or sinking and fixed thereto where required. Any part of a building or structure used to support the scaffold shall be capable of supporting the maximum intended load to be applied. B. USE ADJUSTING SCREWS or other approved methods to adjust to uneven grade conditions. C. BRACING, LEVELING & PLUMBING OF FRAME SCAFFOLDS- 1. Plumb and level all scaffolds as erection proceeds. Do not force frames or braces to fit. Level the scaffold until proper fit can be easily made. 2. Each frame or panel shall be braced by horizontal bracing, cross bracing, diagonal bracing or any combination thereof for securing vertical members together laterally. All brace connections shall be made secure, in accordance with the manufacturer s recommendations. D. BRACING, LEVELING & PLUMBING OF TUBE & CLAMP AND SYSTEM SCAFFOLDS- 1. Posts shall be erected plumb in all directions, with the first level of runners and bearers positioned as close to the base as feasible. The distance between bearers and runners shall not exceed manufacturer s recommendations. 2. Plumb and level all scaffolds as erection proceeds. 3. Fasten all couplers and/or connections securely before assembly of next level. 4. Vertical and/or horizontal diagonal bracing must be installed according to manufacturer s recommendations. E. WHEN FREE STANDING SCAFFOLD TOWERS exceed a height of four (4) times their minimum base dimension, they must be restrained from tipping. (CAL/OSHA and some government agencies require stricter ratio of 3 to 1.) F. TIE CONTINUOUS (RUNNING) SCAFFOLDS TO THE WALL OR STRUCTURE at each end and at least every30 feet of length in between when scaffold height exceeds the maximum allowable free standing dimension. Install additional ties on taller scaffolds as follows: On scaffolds 3 feet or narrower in width, subsequent vertical ties shall be repeated at intervals no greater than every 20 feet. On scaffolds wider than 3 feet, subsequent vertical ties shall be repeated at intervals not greater than 26 feet. The top tie shall be installed as close to the top of the platform as possible; however, no lower from the top than 4 times the scaffold s minimum base dimension. Ties must prevent the scaffold from tipping either into or away from the structure. Stabilize circular or irregular scaffolds in such a manner that the completed scaffold is secure from tipping. Place ties near horizontal members. When scaffolds are fully or partially enclosed, or when scaffolds are subjected to overturning loads, additional ties may be required. Consult a qualified person. G. DO NOT ERECT SCAFFOLDS NEAR ELECTRICAL POWER LINES. Consult a qualified person for advice. H. ACCESS SHALL BE PROVIDED TO ALL PLATFORMS. Do not climb crossbraces or diagonal braces. I. PROVIDE A GUARDRAIL SYSTEM, FALL PROTECTION AND TOEBOARDS WHERE REQUIRED BY THE PREVAILING CODE. ARMOUR EQUIPMENT www.armourscaffold.ca 25

J. BRACKETS AND CANTILEVERED PLATFORMS- 1. Brackets for system scaffolds shall be installed and used in accordance with manufacturer s recommendations. 2. Brackets for frame scaffolds shall be seated correctly with side bracket parallel to the frames and end brackets at 90 degrees to the frames. Brackets shall not be bent or twisted from normal position. Brackets (except mobile brackets designed to carry materials) are to be used as work platforms only and shall not be used for storage of material or equipment. 3. Cantilevered platforms shall be designed, installed and used in accordance with manufacturers recommendations. K. ALL SCAFFOLDING COMPONENTS shall be installed and used in accordance with the manufacturers recommended procedure. L. Components shall not be altered. Scaffold frames and their components manufactured by different companies shall not be intermixed, unless the component parts readily fit together and the resulting scaffold s structural integrity is maintained by the user. M. PLANKING- 1. Working platforms shall cover scaffold bearer as completely as possible. Only scaffold grade wood planking, or fabricated planking and decking meeting scaffold use requirements shall be used. Planks and platforms should rest on bearers only. 2. Check each plank prior to use to be sure plank is not warped, damaged, or otherwise unsafe. 3. Planking shall have at least 12" overlap and extend 6" beyond center of support, or be cleated or restrained at both ends to prevent sliding off supports. 4. Solid sawn lumber, LVL (laminated veneer lumber) or fabricated scaffold planks and platforms (unless cleated or restrained) shall extend over their end supports not less than 6" nor more than 18". This overhang should be guardrailed to prevent access. N. FOR PUTLOGS AND TRUSSES THE FOLLOWING ADDITIONAL GUIDELINES APPLY: 1. Do not cantilever or extend putlogs/trusses as side brackets without thorough consideration of loads to be applied. 2. Install and brace putlogs and trusses in accordance with manufacturer s instructions. O. FOR ROLLING SCAFFOLDS THE FOLLOWING ADDITIONAL GUIDELINES APPLY: 1. RIDING A ROLLING SCAFFOLD IS VERY HAZARDOUS. The SSFI and the SIA do not recommend nor encourage this practice. 2. Casters with plain stems shall be attached to the frames or adjustment screws by pins or other suitable means. 3. No more than 12 inches of the screw jack shall extend between the bottom of the adjusting nut and the top of the caster. 4. Wheels or casters shall be locked to prevent caster rotation and scaffold movement when scaffold is in use. 5. Joints shall be restrained from separation. 6. Use horizontal diagonal bracing near the bottom and at 20 foot intervals measured from the rolling surface. 7. Do not use brackets or other platform extensions without compensating for the overturning effect. 8. The top platform height as measured from the rolling surface of a rolling scaffold must not exceed four (4) times the smallest base dimension (CAL/OSHA and some government agencies require a stricter ratio of 3:1). 9. Cleat or secure all plank. 10. Secure or remove all materials and equipment from platform before moving. 11. Do not attempt to move a rolling scaffold without sufficient help - watch out for holes in floor and overhead obstructions - stabilize against tipping. P. SAFE USE OF SCAFFOLD- 1. Prior to use, inspect scaffold to insure it has not been altered and is in safe working condition. 2. Erected scaffolds and platforms should be inspected continuously by those using them. 3. Exercise caution when entering or leaving a work platform. 4. Do not overload scaffold. Follow manufacturer s safe working load recommendations. 5. Do not jump onto planks or platforms. 6. DO NOT USE ladders or makeshift devices to increase the working height of a scaffold. Do not plank guardrails to increase the height of a scaffold. 7. Climb in access areas only and use both hands. III. WHEN DISMANTLING SCAFFOLDING THE FOLLOWING ADDITIONAL GUIDELINES APPLY: A. Check to assure scaffolding has not been structurally altered in a way which would make it unsafe and, if it has, reconstruct and/or stabilize where necessary before commencing with dismantling procedures. This includes all scaffold ties. B. Visually inspect planks prior to dismantling to be sure they are safe. C. Do not remove a scaffold component without considering the effect of that removal. D. Do not accumulate excess components or equipment on the level being dismantled. E. Do not remove ties until scaffold above has been dismantled to that level. F. Lower dismantled components in an orderly manner. Do not throw off of scaffold. G. Dismantled equipment should be stockpiled in an orderly manner. Since field conditions vary and are beyond the control of the SSFI and the SIA, safe and proper use of scaffolding is the sole responsibility of the user. ARMOUR EQUIPMENT www.armourscaffold.ca 26

RECCOMENDED SCAFFOLDING ERECTION PROCEDURES Introduction This guide has been prepared by the Scaffolding, Shoring & Forming Institute to assist contractors, architects, engineers, dealers, erectors, and users, etc., for the proper use of scaffolding equipment. Scaffolding Safety Rules published by the Institute should be used in conjunction with this publication, as well as the instructions for the use of scaffolding provided by the manufacturer. Safety precautions and requirements prescribed by local, state, and federal agencies, including OSHA, must be followed at all times and persons working with scaffolding systems should be equipped with requisite safety devices. Nomenclature 1. Accessories Those items other than frames and braces used to facilitate the construction of scaffolding towers and structures 2.

Ultimate Load The maximum load which may be placed on the scaffolding causing failure by buckling of column members or yielding of some component. *These terms can be used synonymously. Inspection of Scaffolding Equipment Prior to Erection The 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 damaged welds and any piece of equipment showing damaged welds or rewelding beyond the original factory weld should not be used. The factory weld reference pertains to location and quality of rewelds. While CORROSION, STRAIGHTNESS, 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 than 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. ARMOUR EQUIPMENT www.armourscaffold.ca 27

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 by 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 or 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, workmen shall not be allowed on same until the damaged items have been repaired or replaced. Advanced 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. Adjustment screws should be set to their approximate final adjustment before setting up the scaffolding. At this time, a person should check to see that all panels which require coupling pins have them. 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* 4 times the minimum base dimension. Free standing 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 placed 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 at least 6" beyond the point of support. Also, make sure that the proper bracing is placed between putlogs (trusses). When the span between supporting members is more than 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 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 of 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 end 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 the frame is out of square and should be replaced. 5. Each leg of each 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 Section of Erection. Recheck periodically ties, clamps, etc., for movement. 11. Insure that safe access to work platform(s) is provided. ARMOUR EQUIPMENT www.armourscaffold.ca 28

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 procedures. 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 plank 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. 2. Casters with plain stems shall be attached to the panel or adjustment screw by pins or other suitable means. 3. Do not extend adjusting screws on rolling towers more than 12". 4. The platform height shall not exceed* four (4) times the smallest base dimension unless guyed or otherwise stabilized. 5. Horizontal diagonal braces should be used near the bottom, top and at 20' intervals measured from the rolling surface. 6. When side brackets are used, consideration should be given to the overturning effect these brackets will have upon the stability of the tower. 7. Cross brace every lift-both sides. 8. Install guardrails. ARMOUR EQUIPMENT www.armourscaffold.ca 29
