    • INTRODUCTION1. Compatibility of Excel Modular scaffold Excel scaffold is designed and Engineered to be compatible with standard tube and clamp components (i.e.: Clamps, poles, ladders and ladder brackets) that are currently available within the scaffold industry. These tube and clamp components are generally used for:* Tube and Clamp for tie offs when needed for Seismic Considerations* When needed to transition Horizontally to get around obstacles* When needed to transition Vertically to get around interference* Ladders and ladder brackets for access to work platforms* As needed for structural bracing and reinforcement2. General Erection Criteria Excel was designed and Engineered to be constructed using the same requirements, specified by OSHA and CAL-OSHA, that have been historically used with tube and clamp and other system type scaffolds. Excel expects all users to be familiar with all Federal, State and local regulations governing scaffold construction and use. Excel expects all users to erect, modify or dismantle scaffolding using only qualified and competent personal, with adequate supervision. Excel expects all users to provide supervision that is competent and qualified, that can inspect and sign off on each scaffold before authorization is given for general use. Excel expects all users to follow all common safety guidelines including; pre job briefings, procedure compliance, tagging, flagging, wearing proper PPE, weight loading restrictions, vertical leg placement, use of diagonal bracing, horizontal wraps, proper use of hand rails, midrails, toe boards, safety netting, screw jacks, ladders, metal or wood decking, etc. Excel expects all users to utilize a registered professional engineer (licensed PE) to design and approve drawings as required by OSHA, CAL-OSHA or any other regulatory agency.3. Special Considerations Be extra careful when working with components that telescope. Telescoping components can move/slide while being transported, handled and passed to other workers. Many Excel Scaffold Components swivel, slide or hinge. Use caution when passing to other workers, transporting and installing these items. Insure that all items containing locks or pins are secured before handling, transporting or passing these items to another worker. All material must be inspected prior to use! See Section R for inspection guidelines.
    • Intended Use of Excel Modular scaffold1) Unless otherwise stated all load data presented in this manual includes the OSHA (4:1) Safety Factor.2) Unless otherwise stated all load data presented in this manual is only for downward or compressive loading.3) Excels scaffold material when constructed for normal use is not designed to be up or side loaded in excess of OSHA and ANSI requirements. When conditions require special loading, extra design features must be added to insure proper stability.4) Once installed and completed scaffold should be considered part of the customers plant equipment. Abuse or mistreatment of the scaffold material should not be tolerated.5) The scaffold material should be inspected for damage and repaired after any incident which could affect the integrity of the scaffold material such as: a. ) The scaffold comes into contact with any moving equipment, forklifts, trucks or trailers and other types of mobile equipment. b. ) The scaffold is affected by an unintended load; flanges or piping attached to a crane or come along, objects dropped from above or swung in from the side, etc. c. ) Excessive force is applied to the scaffold from abuse or accidental contact. d. ) The material is modified in any way with a torch, saw or other equipment. e. ) The material is affected from corrosive chemicals that remove the coating and/or damage the base metal. f. ) The material is bent or otherwise damaged.6) The end user should insure that their competent qualified individuals and scaffold erection personnel are trained and fully understand the above requirements.7) When testing of material is required it should be conducted by qualified personnel in a testing environment. Field testing of scaffold components should not be conducted without a formal test plan approved by the manufacturer. 8) All end users must be trained in the proper use of Excel Modular Scaffold. The tech manual is provided as a reference for training. New users should examine the Thumb Rules at the end of the Manual. 9) OSHA requires that inspections must be made by the scaffold builder and end user.10) All material must be inspected prior to use! See Section R for inspection guidelines.

    • Excel Modular Horizontal Bar with Trigger Guard & Lacking Latch Excels newest end connectors function exactly the same as the current end connectors. The enhanced design provides a straighter more aligned horizontal that has a better fit to the cup. All loading and performance remains the same. The new end connectors can be used with the existing horizontals. The new end connectors provide several enhanced features which improve scaffold construction and safety. The main feature is the new safety latch which prevents the horizontal from being accidently disconnected. It provides a new level of safety and security. The horizontal is unlatched by raising thebottom trigger to free the latch and pressing down on both triggers to unhook from the cup.The new end connector design allows metal scaffold boards to be placed the full length of thehorizontal.The new horizontals are capped on the top to prevent debris from entering into the trigger lockingmechanism.In seismic or high vibration areas the bottom latching trigger can optionally be fitted with a spring fora double positive locking system. Also a hole is provided below the top trigger where a bolt canbe added that will prevent the end connector from unlatching.EMSLC-TSM-1001 Section: B-1A Revised: 10/22/10

Ithas standard swivel clamps on each end so it can be fastened to any scaffoldvertical or horizontal. It also is drilled and fitted so a standard vertical pin (LP1) canbe used to connect two or more braces together. This may be desirable when thereis a need to brace longer structures, up to fourteen feet. These braces are designed to be pinned together using standard vertical locking pins to create longer braces where needed. 14 ft Truss When more than one brace is used, the brace Wire Tie should be tied when possible, in the middle with #9 wire or equivalent to a horizontal, vertical or another diagonal.

    • Excel Modular General Guidelines for Bracing The following bracing recommendations are for all, non-seismic scaffolding, built using Excel scaffold components.Bracing and / or tying should be applied to any scaffold where the top of the scaffold has a movement of morethan 6 inches in any direction. The bracing should be placed to run in opposite directions on opposing sides. Itmay be zig-zagged or run all in the same direction. (See Normal Bracing diagram below.) Bracing under the board deck, attached diagonally from vertical to vertical, should be placed every third deck when possible. Normal Bracing (Plain or zig-Zag) Heavy Duty BracingSingle bay scaffolds should be braced on a minimum of two sides and when feasible on all four sides, startingat the bottom and continuing to a minimum of 10 feet from the top of the scaffold.All other bay configurations require bracing placed on one bay for every 30 feet length of scaffold (Generallyevery 4th bay). At a minimum, bracing should be placed on the inside and outside row of the scaffoldingverticals, starting at the bottom and continuing to a minimum of 10 feet from the top of the scaffold.Scaffolds that contain side brackets or outriggers , where there is a possibility of tipping, must also be bracedor tied, with tube and clamp, a min of 2 strands of #9 wire or equivalent, to plant approved structural steelcomponents (i.e.: I-Beams, Handrails, Grating, etc.) The following additional bracing recommendations are for light duty, non-seismic scaffolding, built using Excel scaffold components.Bay widths of 42 inch and less, that are less than 20 feet tall may not require Bracing. The special truss designof Excel Horizontals provides the necessary bracing. Scaffolds above 20 feet tall should be braced usingclamp braces or tube and clamp applied to the bottom of the scaffold leaving an unbraced height of 20 feet orless. (Bracing should always be added if there is excesive movement of the scaffold structure.)Scaffolds with a deck height less than 10 ft. do not require bracing provided they are tied off, with tube andclamp, 2 strands of #9 wire or equivalent, to plant approved structural steel components (i.e.: I-Beams,Handrails, Grating, etc.). The following additional bracing recommendations are for medium and heavy duty, non-seismic scaffolding, built using Excel scaffold components.Heavy duty scaffolds should have as much bracing as required to meet the desired loading. Bracing and / ortying should be placed on all sides of the scaffold. Multibay scaffolds should have bracing on every other bay,front middle and back rows. (see Heavy duty bracing diagram above.)

    • Code of Safe PracticesExcel recognizes that the scaffold industry is considered "inherently dangerous". It is the intent of this section ofthe procedures manual to provide pertinent guidelines for the proper, safe use, and maintenance of scaffoldcomponents and structures. These guidelines are generalities and do not intend to cover every specific situationor component; they do not purport to be all inclusive nor to supplant other regulatory and precautionary measuresfor the safe use of scaffold in usual or unusual conditions. The primary codes or regulations are those promulgatedby OSHA. They are Federal Laws intended to provide a safe workplace by providing minimum referenceguidelines upon which related activities should be carried out. It shall be the responsibility of all users / erectors toavail himself and to comply with all applicable codes, regulations, standard and common sense practices designedto proport safety in the erection, use and dismantling of scaffold. General Guidelines Prior To Use Of Scaffolding1.) Jobsite conditions within the boundaries of a refinery, chemical plant, manufacturing plant, paper and pulp mill,power plant, or construction site may vary, and each presents unique circumstances. Efficient and proper planningof each job must be done by a competent, qualified person: OSHA 1926.451 (a) (3) no scaffold shall be erected,moved, dismantled or altered except under the supervision of competent persons.2.) The jobsite should be inspected and supervision be familiarized with proper access, proximity of power orprocess lines, obstructions, ground conditions, openings or pits, strength of supporting structure, interference withother workers, overhead protection, wind / weather protection and environmental hazards. These conditions mustbe evaluated and adequately provided for. Also, consider the protection of people who will be passing or workingbeneath or around scaffold structures.3.) The work to be done and the number of persons involved must be determined to properly calculate theloading; the total loads and the supporting ground or structure must be considered when designing scaffoldstructure - leg spacing, adequate sills, horizontal bracing, etc.4.) Stationary scaffolds over 125 ft. in height and rolling towers over 60 ft. in height must be designed by aprofessional engineer.5.) All equipment must be inspected to insure that it is in good condition. Damaged or deteriorated equipmentshould not be used and must be removed from service.6.) Scaffolds must be designed and used in accordance with the manufacturers specifications andrecommendations. Do not intermix different brands of scaffold, unless authorized by the manufacturer, or plan touse materials in any manner other than what the manufacturer intended their design to accommodate.7.) When planning the job, remember to use common sense, sound judgment and qualified reasoning for thefollowing: A. provide adequate foundations B. provide proper access C. provide proper bracing D. provide proper handrails and toe boards E. provide adequate decking materials F. design scaffold structure on components to adequately compensate for all intended loads G. use only qualified personnel who are in good shape - emotionally and physically8.) Read, understand and comply with all Federal (OSHA) State and local codes and regulations pertaining toscaffold erection and removal.9) When covering scaffold with plastic, tarps or other types of solid material the user must considerall wind and/or snow loading. Excel recommends that all users consult with an Engineer to insurethe proper bracing for the maximum expected wind or snow loads.EMSLC-TSM-1001 Section R-1 Revised: 12/31/05
    • GIVE TO SCAFFOLD ERECTOR & USER OR POST ON JOB CODE OF SAFE PRACTICES FOR FRAME SCAFFOLDS, SYSTEM SCAFFOLDS, TUBE AND CLAMP SCAFFOLDS & ROLLING SCAFFOLDS DEVELOPED FOR INDUSTRY BY SCAFFOLD INDUSTRY ASSOCIATION, INC.It shall be the responsibility of all users to read and comply with the following common sense guidelines which aredesigned to promote safety in the erecting, dismantling and use of scaffolds. These guidelines do not purport to beall-inclusive nor to supplant or replace other additional safety and precautionary measures to cover usual orunusual conditions. If these guidelines in any way conflict with any state, local, federal or other governmentstatute or regulation, said statue or regulation shall supersede these guidelines and it shall be the responsibility ofeach user to comply therewith. 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. 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 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. 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 qualified 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. II. GUIDELINES FOR ERECTION AND USE OF SCAFFOLDS A. SCAFFOLD BASE MUST BE SET ON 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 instead of blocking to adjust to uneven grade conditions. C. BRACING, LEVELING & PLUMBING OF FRAME SCAFFOLDS - 1 Plumb and level all scaffolds as the erection proceeds. Do not force frames or braces to fit - level the scaffold until proper fit can easily be made.EMSLC-TSM-1001 Section R-2 Revised: 12/31/05
    • 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 manufacturers 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 manufacturers recommended procedures. 2 PLUMB, LEVEL AND TIE 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 manufacturers recommendations. E. TIE CONTINUOUS (RUNNING) SCAFFOLDS TO THE WALL OR STRUCTURE at each end and at least every 30 feet of length when scaffold height exceeds the maximum allowable free standing dimension. Begin ties or stabilizers when the scaffold height exceeds that dimension, and repeat at vertical intervals not greater than 26 feet. The top anchor shall be placed no lower than four (4) times the base dimension from the top of the completed scaffold. Anchors must prevent scaffold from tipping into or away from wall or structure. Stabilize circular or irregular scaffolds in such a manner that completed scaffold is secure and restrained from tipping. When scaffolds are partially or fully enclosed or subjected to overturning loads, specific precautions shall be taken to insure the frequency and accuracy of ties to the wall and structure. Due to increased loads resulting from wind or overturning loads the scaffolding component to which ties are subjected shall be checked for additional loads. F. WHEN FREE STANDING SCAFFOLD TOWERS exceed four (4) times their minimum base dimension vertically, they must be restrained from tipping. (CAL/OSHA and some government agencies require stricter ratio of 3 to 1.) G. DO NOT ERECT SCAFFOLDS NEAR ELECTRICAL POWER LINES UNLESS PROPER PRECAUTIONS ARE TAKEN. Consult the power service company for advice. H. A MEANS OF ACCESS TO ALL PLATFORMS SHALL BE PROVIDED. I. DO NOT USE ladders or makeshift devices on top of scaffolds to increase the height. J. PROVIDE GUARDRAILS AND MID-RAILS AT EACH WORKING PLATFORM LEVEL where open sides and ends exist, and toe boards where required by code. K. BRACKETS AND CANTILEVERED PLATFORMS - 1 Brackets for SYSTEM SCAFFOLDS shall be installed and used in accordance with manufacturers 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. L. ALL SCAFFOLDING COMPONENTS shall be installed and used in accordance with the manufacturers recommended procedure. Components shall not be altered in the field. Scaffold frames and their components manufactured by different companies shall not be intermixed, unless the component parts readily fit together and the resulting scaffolds structural integrity is maintained by the user.EMSLC-TSM-1001 Section R-3 Revised: 12/31/05
    • 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. 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 not be used as a work platform. N. FOR "PUTLOGS" AND "TRUSSES" THE FOLLOWING ADDITIONAL GUIDELINES APPLY: 1 Do not cantilever or extend putlogs / trusses as side brackets without thorough consideration for loads to be applied. 2 Putlogs / trusses should be extended at least 6" beyond point of support. 3 Place recommended bracing between putlogs / trusses when the span of putlog / truss is more than 12 feet. O. FOR ROLLING SCAFFOLDS THE FOLLOWING ADDITIONAL GUIDELINES APPLY: 1 RIDING A ROLLING SCAFFOLD IS VERY HAZARDOUS. The Scaffold Industry Association does not recommend nor encourage this practice. However, if you choose to do so, be sure to follow all state, federal or other governmental guidelines. 2 Casters with plain stems shall be attached to the panel or adjustment screw 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 provided with a locking means to prevent caster rotation and scaffold movement and kept locked. 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 platform height of a Rolling Scaffold must not exceed four (4) times the smallest base Government agencies require a stricter ratio or 3 to 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 manufacturers safe working load recommendations. 5 Do not jump onto planks or platforms. 6 Do not use ladders or makeshift devices on top of working platforms to increase the height or provide access from above. 7 Climb in access areas only and USE BOTH HANDS.EMSLC-TSM-1001 Section R-4 Revised: 12/31/05
    • III. WHEN DISMANTLING SCAFFOLDING THE FOLLOWING ADDITIONAL GUIDELINES APPLY: A. Check to insure scaffolding has not been structurally altered in a way which would make it unsafe and, if it has, reconstruct where necessary before commencing with dismantling procedures. This includes all scaffold ties. B. Visually inspect plank prior to dismantling to be sure they are safe. C. Consideration must be given as to the effect removal of a component will have on the rest of the scaffold prior to that components removal. D. Do not accumulate excess components or equipment on the level being dismantled. E. Do not remove ties until scaffold above has been removed (dismantled). F. Lower dismantled components in an orderly manner. Do not throw off of scaffold. G. Dismantled equipment should be stockpiled in an orderly manner. H. FOLLOW ERECTION PROCEDURES AND USER MANUALS.These safety guidelines (Codes of Safe Practice) set forth common sense procedures for safely erecting,dismantling and using scaffolding equipment. However, equipment and scaffolding systems differ, andaccordingly, reference must always be made to the instructions and procedures of the supplier and / ormanufacturer of the equipment.Since field conditions vary and are beyond the control of the Scaffold Industry Association, safe and proper use ofscaffolding is the sole responsibility of the user.EMSLC-TSM-1001 Section R-5 Revised: 12/31/05
    • OSHA Compliance ofExcel Modular Scaffold.All Excel Modular Scaffold equipment can be used to construct scaffoldsthat are 100% compliant with OSHA regulations.It is important to understand that OSHA does not regulate how scaffoldmaterial is manufactured. The manufacture of scaffold material is coveredby ANSI and ASTM specifications. OSHA 1926.450-453,1053 governs theconstruction of scaffolds using different types of scaffold material. The onlyrestrictions that OSHA places on scaffold material are a 4:1 safety factor andloading values for decks, handrails and ladders.When Excel Modular Scaffold material is assembled according to theloading and assembly requirements in Excel Technical Manual thecompleted scaffold will meet the OSHA regulations.This document is an explanation of how Excel Modular Scaffold Materialmeets the OSHA 1926.450-453,1053 documents.Ultimate Load:The load values listed in our technical manual reflect that all Excel ScaffoldComponents have been tested to a minimum safety factor of 4:1.1.A.) OSHA Standard requires a 4:1 safety factor for scaffold material thatdoes not contain suspension rope. 1926.451 (a)(1) Except as provided in paragraphs (a)(2), (a)(3), (a)(4), (a)(5) and (g) of this section, each scaffold and scaffold component shall be capableEMSLC-TSM-1001 R-6 Revised: 12/31/05

The OSHA standard for handrails is 200 lbs. 1926.451(g)(1)(iv) Each employee on a self-contained adjustable scaffold shall be protected by a guardrail system (with minimum 200 pound toprail capacity) when the platform is supported by the frame structure, and by both a personal fall arrest system and a guardrail system (with minimum 200 pound toprail capacity) when the platform is supported by ropes; All Excel Scaffold Handrails exceed this value.3.A.) OSHA provides for three deck-loading values 25-lb/sq ft, 50-lb/sq ftand 75-lb/sq ft. Index to Appendix A for Subpart L 1. (c) Fabricated planks and platforms may be used in lieu of solid sawn wood planks. Maximum spans for such units shall be as recommended by the manufacturer based on the maximum intended load being calculated as follows:_____________________________________________________________ Rated load capacity | Intended load_____________________________________________________________ | Light-duty....... | * 25 pounds per square foot applied | uniformly over the entire span area. Medium-duty. .| * 50 pounds per square foot applied | uniformly over the entire span area. Heavy-duty.... .| * 75 pounds per square foot applied | uniformly over the entire span area.EMSLC-TSM-1001 R-7 Revised: 12/31/05

    • Scaffold inspection guidelinesDuring manufacture Excel Modular Scaffold goes through a very intensive inspection program.Each part is handled and inspected two times. Items are then randomly selected fornondestructive testing and a final inspection is performed. Further visual inspection isperformed as the material is loaded for shipment to any jobsite.Even with this intensive inspection system it is still the responsibility of the end user to insurethat each piece of scaffold material installed is free of defects.Scaffolds are usually built by one craft group and then work is performed on and around thescaffold by many different craft groups. During normal use it is possible that scaffoldcomponents will become damaged. The following are general guidelines to aid the end user inidentifying potential problems with Excel Modular Scaffold material. This list is by no meansall inclusive and is provided only as a general guide.All components must be checked every time they are used, prior to installation or removal forany visible damage, missing or broken welds, deformed or dented parts that may affect thestrength of the item, saw marks, welding burn marks, excessive rust or chemical damage.Material must be removed from service any time rust or chemical damage has affected thestrength or fit of the material, this is especially critical with the trigger and spring assembly.End users should immediately contact Excel Modular Scaffold & Leasing Company (877)668-6657 or (225) 777-4157 regarding any abnormal issues or concerns.For all items with End connectors:The end connector must be undamaged and the trigger unbroken.

    • Design of Seismic ScaffoldingDesign and construction of scaffolding in safety related areas (near rotating equipment, instrumenttubing, trip sensitive equipment, control panels, etc.) does require additional precautions. Theseguidelines are not intended to be all inclusive. The clients engineering department should beconsulted for exact guidelines and any site specific requirements.The primary concern associated with scaffold installation in Safety Related areas involves thedamage that could be caused to delicate equipment if the scaffold should slide, change shape,collapse or overturn. In order to prevent any scaffold material from coming into contact with safetyrelated system equipment the following guidelines should be observed:Where existing plant guidelines exist for tube and clamp or other system scaffold that are morestringent, the most stringent guidelines should always be used.1) The scaffold should be designed to meet all federal, state, local and plant safety regulations.2) The height of the scaffold should not exceed three (3) times the smallest base dimension.3) The scaffold should be fastened, at the verticals or horizontals, with tube and clamp orequivalent to plant approved structural steel components (i.e.: I-Beams, Handrails, Grating, etc.) atthe top, the middle and the base of the scaffold. Whenever possible Excel Click Lock connectionsshould be used. Securing the scaffold jacks to the floor will be effective for securing the base ofthe scaffold. Diagonal braces and side brackets must not be used to secure the scaffold.4) To prevent movement, the scaffold should be secured at two (2) separate locations, on oppositecorners, (see sample bracing diagrams). Scaffolds with more than one bay should be secured atas many outside verticals as possible, (see sample multi-bay scaffold diagram).5) All scaffolds installed near or around safety related equipment must be secured at as manyoutside verticals as possible.6) The scaffold must have an installed board deck or should be braced or tied to prevent thescaffold from changing shape, (see sample bracing diagrams).7) All pins connecting verticals and all horizontals must be securely fastened.8) No unnecessary items or scaffold material should be left unsecured on the scaffold at any time.9) The scaffold should not be left unattended, at any time, until it is braced and/or tied adequatelyand any loose tools are secured prior to leaving it.10) The scaffold should be provided with screens, mesh or other suitable means to preventmaterials from being dropped on safety related equipment. Tying off equipment and tools isacceptable.11) Material or equipment should not be left unattended on any scaffold when the scaffold is not inuse.EMSLC-TSM-1001 Section S-1 Revised: 12/31/05
    • Design of Seismic Scaffolding12) Diagonal braces must be installed on all possible sides. Diagonal braces with Excel endconnectors must be wire tied (with 1 strand of #9 wire or equivalent) at the ends. When possible allbraces should be wire tied (with 1 strand of #9 wire or equivalent) in the center.13) Horizontal wraps should be placed at 3.5 feet intervals.14) A scaffold with wooden parts, including decking, should be free from holes, saw cuts, splitsand gaps.15) Decking should be completely placed, with no holes or missing boards, to help maintain asquare and ridged scaffold.16) All platform decking must be secured (i.e.: wire tied) to the horizontal ledgers that are used forsupport.17) The scaffold must be designed to allow access to safety related equipment at all times.18) The scaffold should be removed immediately upon job completion.EMSLC-TSM-1001 Section S-2 Revised: 12/31/05

    • Excel Modular Scaffold encourages users of its scaffold material either through independent testing or with theaid of a Professional Engineer to develop their own tie off guidelines, which may be different from those listedabove.Excel Modular Scaffold may give different guidelines to customers depending on the specific needs of thecustomer and the type of scaffold maintenance program in place.Note:"Rescue considerations." As required by 1926.502(d)(20), when personal fall arrest systems are used, the employer mustinsure that employees can be promptly rescued or can rescue themselves should a fall occur. The availability of rescuepersonnel, ladders or other rescue equipment should be evaluated. In some situations, equipment which allowsemployees to rescue themselves after the fall has been arrested may be desirable, such as devices which have descent"Inspection considerations." As required by 1926.502(d)(21), personal fall arrest systems must be regularly inspected. Anycomponent with any significant defect, such as cuts, tears, abrasions, mold, or undue stretching; alterations or additionswhich might affect its efficiency; damage due to deterioration; contact with fire, acids, or other corrosives; distorted hooksor faulty hook springs; tongues unfitted to the shoulder of buckles; loose or damaged mountings; non-functioning parts; orwearing or internal deterioration in the ropes must be withdrawn from service immediately, and should be tagged ormarked as unusable, or destroyed.Note:Any material that is subjected to a load from a fall must be replaced, even if there is no visible damage to the scaffoldmaterial. This includes verticals which may have been bent from the fall stress.If it is not possible to immediately replace the material because of structural considerations the material must be bracedwith tube & clamp or equivalent means and inspected by a qualified individual to insure it is safe for continued use. Thematerial must be replaced as soon as it is possible.EMSLC-TSM-1001 Section T-4 Revised: 01/15/12 Copyright @ 1997

    • "Key Thumb Rules To Remember When Building Excel Scaffold Towers"8) Do not use a Porta Band Saw mentality when building with Excel, modular materialis typically more expensive than tube & clamp and should only be cut as a last resort, ifyou must cut vertical legs always cut them on the top. Keep in mind there will beinvoices for damaged material.9) Always start tower erection with adjustable screw jacks. You must assume that thefloor is not level. Always place screw jacks in middle of threads or approximately 6" offthe ground.10) Always do a visual inspection of the horizontal bars, as the scaffold is beingconstructed, to make sure the triggers are properly locked in place and that they are inthe up position.11) Light tapping the horizontal bars on top of the end connector is allowed to get thepositive locking trigger assembly properly locked into the cups / node points on thevertical leg12) Random field testing of Excel scaffold components by unqualified personnel is notallowed, any concerns, issues or questions with supplemental testing should always bereferred to the manufacturing facility in Walker LA to the attention of Ken Hensley at225-777-4775 Ext-22313) Must initially use a level to get the tower totally plumb / level at the very beginningon the very first base wrap or you will fight bar placement all the way up.14) Vertical legs post are called "VPs" based on the number of cups: VP-2 is theshortest and VP-20 is the longest, always even numbers, approx. one foot in length forevery two cups. Remember that VP-2s have very limited use and are only used at thevery top of a vertical leg to add the final cups need to attached the top handrail, theyare not used for any other application15) Vertical cups (node point, moment connections) are on 5 3/4" centers all the waythe entire vertical leg assembly for better flexibility.16) Always have two hands on the components at any one time, especially whensetting another set of vertical legs on an existing set of vertical legs.17) When setting a vertical leg on top of an existing leg, one hand shall support theupper leg while the other hand depresses the spring clip, then slowly lower the topvertical leg down. Slightly twist the vertical until the spring clip locks into place. Do notDrop the upper vertical leg onto the lower vertical leg coupling pin.18) To remove vertical legs that are connected, depress spring clip, twist (clockwise orcounter clockwise) the upper vertical leg approximately 20 degrees, and with bothhands, lift to remove from lower vertical leg coupling pin.

Manual chain line) any type of telescoping brace (adjustablehandrail or diagonal brace) insure components are secured together by clip prior toupward or downward movement. This applies to adjustable toe boards as well24) Diagonal Extendable Braces (DEBs) typically require a 12 cup split between thetop connector on one end and the bottom connector on the other end, eight cupsbetween the two ends. Swivel braces (DSBs, DPBs) and Combination Braces (DCBs)may fit differently.25) Do not exceed a maximum of 14 cups (6 6") spacing between horizontal boarddeck wraps from the top of lower horz. bar wrap to the top of the next horz. bar wrap.26) When installing your mid rail and top hand rail you use the following spacing fromthe board deck : skip two cups..hit two cups..skip two cups ..hit two cups and you willbe right in line with OSHA requirements, does not require tape measure.27) Standard hand rail corner posts are always comprised of VP-8 vertical legassemblies (minimum eight cup leg length).28) When installing telescoping toe boards, make sure that you install the toe boardend connector in the unlocked position to the vertical leg and tighten the half clamp justenough so that it wont fall off, after you have all the toe boards installed into the toeboard end connector, then line everything up nice and straight and tighten up the halfclamp as the very last step.29) Clean verticals (cup less) are used to get through very tight places (cable trays,piping runs, etc) where standard vertical legs with cups will not fit. Clean verticals mustnot exceed 69"30) When adding a leg in the middle of thin air (i.e.; in the middle of a horizontal bearerbar using and IHA or on top of a side bracket or cantilever) that does not go all the wayto the ground, you can not exceed 25 lbs per FT2 unless you support it back to aprimary leg with a second diagonal brace.

Additionally, you should always install the vertical ladder with themale end up of the ladder pointed up and the female end pointed down.36) When installing a rope pulley hoists above the top hand rail you must always installanother complete wrap or horizontal bars at least four feet above top hand rail to tie inwith the rest of the tower.37) The approved tie off area for fall protection is above the top hand rail where twohorizontals bars connect to a vertical leg, refer to the tech manual for exactly how touse horizontal bars which are now approved for tie off purposes38) When installing a Yo Yo adapter above the top hand rail you must always installanother entire board deck wrap at least four feet above top hand rail to tie in with therest of tower.39) When building hanging Excel towers insure that you install safety clamp on to thevertical leg directly above the Excel horizontal bar that will be holding the weight of theleg going down.40) Always use handrails and step in the center of the treads. Always walk down thestair tower, do not run, do not skip any steps.41) Clamp Bolts should have between 40 and 65 lbs tension. Over tightening coulddamage the threads, bolt or item the clamp is attached to.42) Never Use RBC (Rigid Beam Clamps) or SBC (Swivel Beam Clamps) to hang orsupport a scaffold with the bolts.

(A weight sheet can be made from our current List Price Sheet.)44) It is a very sound work practice to get the truck driver to go directly to the closestCAT certified weigh scale after they leave the job site and double check the totalloaded weight so that if the truck is over weight the driver can quickly return to the siteto get some material removed to lower the gross vehicle weight so that it is incompliance with the Federal DOT requirements.45) When shipping Excel scaffold material take adequate time upfront and be careful tomake sure that it is always properly racked, stacked, banded prior to loading onto theflat bed trailer to prevent inadvertent shifting during transit46) When shipping Excel scaffold material make sure to always use the proper racksand baskets. Do not make your own temporary racks out of miscellaneous scaffoldparts that could come apart when loaded, unloaded or during transit which could resultin possible injury to personnel or property.47) When loading racks and baskets of Excel scaffold material onto flat bed trailers,take adequate time upfront to make sure that those items are properly secured to theflat bed trailer using multiple ratchet tie down straps for each and every level and row ofbaskets and racks to prevent shifting during transit.48) When unloading racks and baskets of Excel scaffold material off of flat bed trailers,inspect the load to see if any items have shifted during transit prior to removing any ofthe ratchet tie down straps. Insure that personnel do not stand below the rows of racksbeing undone in case any material comes loose and falls off the truck.49) Casters are the easiest item to overload when building a rolling scaffold. Scaffoldsshould be limited to two (2) work decks, 15 ft high when using 8 inch casters and three(3) work decks, 21 ft high when using 12 inch casters.50) Always inspect horizontal bars prior to installation to insure that the trigger andspring are properly installed and functioning correctly. If you find an end connector witha broken trigger or weak spring do not use that component, pull it out of service and tagit for repair. Additionally, when installing ledgers or bearers bars do not let go of the baruntil you verify that it is properly locked into place and that the trigger is resting in theup position.

All material must be evenly balanced in the rack. 2.) All material must be secured from sliding. (2 ratchet straps, 2 wraps of banding or other approved method of securing the material shall be used.) 3.) All material must be secured to the rack. (This can be accomplished by the same strapping/banding required above.) 4.) Standard rigging procedures should be used to prevent movement of the straps while lifting the load. (Use of a spreader bar when possible is preferred.)Note:1.) All OSHA and plant safety regulations governing rigging and material handling must be followed.2.) All loose material must be removed or secured before lifting.3.) Spreader beams must be used so that the lifting load on all vertical posts is applied in an upwarddirection.4.) The scaffold must be properly braced to prevent deformation during movement.5.) Scaffold weight loads must be calculated to prevent the overloading of any scaffold or liftingcomponent.6.) All scaffold components, (deck boards, etc.) must be secured to the scaffold.Clamp Bolts should have between 40 and 65 lbs tension. Over tightening could damage the threadsbolt or item the clamp is attached to.All material must be inspected prior to use!

    • Excel Modular Wood PlanksExcel only purchases quality wood planks that meet the OSHA requirments for lumber type and density.The following is the required inspection/storage procedure for boards. The boards should be inspected before they are put into service, for damage and wear. All planks must be inspected routinely for damage and wear, so that they can be replaced as quickly as 1.) necessary. Identification of damage. Employees shall be trained to recognize the following types of wear / 2.) damage: a.) Decay: boards should be examined to determine if age / weathering / wear is excessive. Wood ages and reacts to usage and will begin to show checks, splits and notches. These will vary in degree, depending on the loads a plank has carried, the weather to which it has been exposed, the length of time it has been in use, etc. Planks with splits – that is, cracks that go completely through the wood – for more than a few inches should not remain in service, as they may no longer maintain the necessary load-bearing capacity. Planks with checks – cracks that are on the surface only and do not go completely through the wood – should be watched, as the checks may develop into splits over time. b.) Damage: does the board contain any notches, cuts or other visual damage that would render it unsafe to use? Notched plank can lead to problems since, essentially, a potion of the plank is now missing, thereby weakening the plank at that particular area. If a scaffold plank has been used as a mudsill, it should not be returned to service on a platform. Moisture from standing water as well as point-loading from the scaffold legs may have weakened it, making it unable to bear the weight that will be placed on it. c.) Chemical/Heat damage: Has the board been exposed to excessive chemicals/heat (soaked with oil, scorch marks?) Scaffold planks that have visible chemical or scorch marks must be removed from service. d.) Surface covering: Is the surface free from items that may cause a slip, (oil/tar/etc.) OSHA [1926.451(b)(9)] says that scaffold planks that have accumulated layers of mortar, grout, paint, plaster, etc., are not permitted to remain in service, since it is impossible to determine their conditions. Dangerous splits may be hidden underneath those coatings. e.) Shrinkage: Has the board size decreased past its useful size? f.) Deflection: The flex or “give” of a plank can indicate its condition. OSHA calls for deflection criteria of L/60 (the length of span in inches divided by 60) to get the maximum deflection limit at center span in inches. An example would be a seven-foot (84-inch) span between scaffold frame supports: 84/60 = 1.40 inches. Therefore, you’d never want to allow a plank to deflect more than 1- 3/8 inches at the middle of that length span, regardless of type of plank being used. Only sample testing should be performed since test loading can damage the board.

    • Excel Modular Wood PlanksStorage: When not in use, all wood planks, should be stored above ground on dunnage to keep moisture fromentering the bottom of the boards. Additionally, all boards should have some sort of lath or stickers betweenlayers to allow for air circulation through the boards. Most important, a tarp or something as simple as a sheetof plywood should be placed over the top of the boards to prevent moisture from dropping down through thestack.
