INTRODUCTION1. Compatibility of Excel Modular scaffold

Excel scaffold is designed and Engineered to be compatible with standard tube and clampcomponents (i.e.: Clamps, poles, ladders and ladder brackets) that are currently available withinthe scaffold industry. These tube and clamp components are generally used for:

* Tube and Clamp for tie off's 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 reinforcement

2. General Erection Criteria

Excel was designed and Engineered to be constructed using the same requirements, specified byOSHA and CAL-OSHA, that have been historically used with tube and clamp and other systemtype scaffolds.

Excel expects all users to be familiar with all Federal, State and local regulations governingscaffold construction and use.

Excel expects all users to erect, modify or dismantle scaffolding using only qualified andcompetent personal, with adequate supervision.

Excel expects all users to provide supervision that is competent and qualified, that can inspectand 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, verticalleg placement, use of diagonal bracing, horizontal wraps, proper use of hand rails, midrails, toeboards, safety netting, screw jacks, ladders, metal or wood decking, etc.

Excel expects all users to utilize a registered professional engineer (licensed PE) to design andapprove 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.

Page 5: Tech Manual 7162009 Exel Scaffolding

Intended Use of Excel Modular scaffold1) Unless otherwise stated all load data presented in this manual is only for downward or

compressive loading.

2) Excels scaffold material when constructed for normal use is not designed to be up or side loadedin excess of OSHA and ANSI requirements. When conditions require special loading, extradesign features must be added to insure proper stability.

3) Once installed and completed scaffold should be considered part of the customers plantequipment. Abuse or mistreatment of the scaffold material should not be tolerated.

4) The scaffold material should be inspected for damage and repaired after any incident which couldaffect the integrity of the scaffold material such as:a. ) The scaffold comes into contact with any moving equipment, forklifts, trucks or trailers andother types of mobile equipment.b. ) The scaffold is affected by an unintended load; flanges or piping attached to a crane or comealong, 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 thebase metal.f. ) The material is bent or otherwise damaged.

5) The end user should insure that their competent qualified individuals and scaffold erectionpersonnel are trained and fully understand the above requirements.

6) When testing of material is required it should be conducted by qualified personnel in a testingenvironment. Field testing of scaffold components should not be conducted without a formal testplan approved by the manufacturer.

7) All end users must be trained in the proper use of Excel Modular Scaffold. The tech manual isprovided as a reference for training. New users should examine the Thumb Rules at the end ofthe Manual.

8) OSHA requires that inspections must be made by the scaffold builder and end user.9) All material must be inspected prior to use! See Section R for inspection guidelines.

Excel Modular Diagonal Pin BraceThe Excel Modular Diagonal Pin Brace is designed to be a multipurpose brace. Ithas standard swivel clamps on each end so it can be fastened to any scaffold vertical 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 pinnedtogether using standard vertical lockingpins to create longer braces where needed.

When more than one brace is used, the braceshould be tied when possible, in the middlewith #9 wire or equivalent to a horizontal,vertical or another diagonal.When braces are connected together themiddle clamps may or may not be used.

Excel Modular General Guidelines for Bracing

Normal Bracing (Plain or zig-Zag) Heavy Duty 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.)

Single 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.

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.)

EMSLC-TSM-1001 Section: C-6 Revised: 12/31/05

Bracing under the board deck, attached diagonally from vertical to vertical, should be placed every third deck when possible.

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 minimum requirement for tying is two (2) pieces of tube & clamp secured to the structure with beam clamps from a vertical on the opposite side of the scaffold to a permanent structure. This is in addition to tying required by Federal, State or Local regulations. The scaffold must be secured before the side brackets are installed. There is no width requirment of the scaffold the folding side bracket is being attached to because the scaffold MUST be secured to a permanent structure to prevent tipping.

The scaffold supporting a folding side bracket must be properly braced and secured. Horizontal bars must be placed at the deck location and a support bar must be placed at the diagonal

connection.

Unfold the side bracket and let all of thebracket except the top end connector swing toward the ground.

Connect the top end connector to the desired point on the scaffold.

Have the person on a lower location, or if requiredmove to the lower location and raise the side bracket,using the bottom end connector, until the top baris level. Connect the bottom end connector.

Repeat the installation procedurewith a second folding side bracketof the same size.

Always use proper tie-off when handlingside brackets.

Adjust the side bracets so they are square wit the rest of the scaffold.This is best performed by gently shakingthe side bracket allowing the connectorsto rotate around the cups.

Place the first scaffold board on the side bracket.Insure that the board is correctly setting on the bracket.

Slide the board out toward the end of the sidebracket. Begin adding the rest of the boardsplacing them on the bracket and sliding them out toward the other boards.

General Guidelines Prior To Use Of Scaffolding

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.

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.

E. provide adequate decking materials

Section R-1

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 physically

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.

D. provide proper handrails and toe boards

4.) Stationary scaffolds over 125 ft. in height and rolling towers over 60 ft. in height must be designed by aprofessional engineer.

6.) Scaffolds must be designed and used in accordance with the manufacturer's 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.

OSHA Compliance of Excel Modular Scaffold.

All Excel Modular Scaffold equipment can be used to construct scaffolds that are 100% compliant with OSHA regulations. It is important to understand that OSHA does not regulate how scaffold material is manufactured. The manufacture of scaffold material is covered by ANSI and ASTM specifications. OSHA 1926.450-453,1053 governs the construction of scaffolds using different types of scaffold material. The only restrictions that OSHA places on scaffold material are a 4:1 safety factor and loading values for decks, handrails and ladders. When Excel Modular Scaffold material is assembled according to the loading and assembly requirements in Excel Technical Manual the completed scaffold will meet the OSHA regulations. This document is an explanation of how Excel Modular Scaffold Material meets the OSHA 1926.450-453,1053 documents. Ultimate Load: The load values listed in our technical manual reflect that all Excel Scaffold Components have been tested to a minimum safety factor of 4:1. 1.A.) OSHA Standard requires a 4:1 safety factor for scaffold material that does 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 capable

Page 81: Tech Manual 7162009 Exel Scaffolding

EMSLC-TSM-1001 R-7 Revised: 12/31/05

of supporting, without failure, its own weight and at least 4 times the maximum intended load applied or transmitted to it.

Section (a)(2) refers to counterweights, Section (a)(3) and (a)(4), suspension rope; Section (a)(5) scaffold hoist and (g) handrails. Excel Scaffold material is all tested to a better than 4:1 safety factor. ISO 9001-2000 test documentation is available upon request. 2.A.) 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 ft and 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.

Page 82: Tech Manual 7162009 Exel Scaffolding

EMSLC-TSM-1001 R-8 Revised: 12/31/05

Note: Platform units used to make scaffold platforms intended for light-duty use shall be capable of supporting at least 25 pounds per square foot applied uniformly over the entire unit-span area, or a 250-pound point load placed on the unit at the center of the span, whichever load produces the greater shear force. Excel Technical manual pages B3, B4, B6, B7, G1, H7, H8 define how to construct proper deck sizes to meet the above loading requirements.

Scaffold inspection guidelines During manufacture Excel Modular Scaffold goes through a very intensive inspection program. Each part is handled and inspected two times. Items are then randomly selected for non destructive testing and a final inspection is performed. Further visual inspection is performed 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 insure that 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 the scaffold by many different craft groups. During normal use it is possible that scaffold components will become damaged. The following are general guidelines to aid the end user in identifying potential problems with Excel Modular Scaffold material. This list is by no means all inclusive and is provided only as a general guide. All components must be checked every time they are used, prior to installation or removal for any visible damage, missing or broken welds, deformed or dented parts that may affect the strength 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 the strength 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. Look for missing bolts or nuts that hold in the trigger or spring.

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.

Design of Seismic Scaffolding

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:

Design 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.

2) The height of the scaffold should not exceed three (3) times the smallest base dimension.

When building scaffold using Universal Beam Tube Clamps:1.) The scaffold should be designed for light duty use and deck loading must not exceed

25 lbs/sq ft.2.) The maximum horizontal used for the cantilever must not exceed 5 ft.3.) The maximum size of the work deck built using the Excel heavy duty beam clamps shall not

exceed 5' x 10' (50 ft2) and the maximum deck loading on this platform shall not exceed1,200 lbs (25 lbs ft2)

4.) Page D-4, D-5 and D-6 (Diagonal Brace Used as a Side Bracket) must be followed whenbuilding a cantilever scaffold.

5.) Each scaffold will require a minimum of six points of attachment.6.) Multiple clamps should be used to reduce the loading when building any scaffold. Standard

beam clamps should be used as backup clamps (to prevent slip) when a scaffold may beinstalled in high vibration areas or for extended periods of time.

Note:All bolts should be inspected and tightened regularly before use.

Clamp Bolt tension greatly affects the slip loading.Clamp Bolts should have between 40 and 65 lbs tension. Over tightening could damage the threads, bolt or item the clamp is attached to. Under tightening could result in clamps slipping at lower than rated loads.

All material must be inspected prior to use! See Section R for inspection guidelines.

Charges For Return Of Excel Scaffold Material That Is Not Properly Sorted and Racked

Upon completion of the project, Excel requires that all scaffold material, be properly segregated and racked by individual components. Prior to being released for transport, customers must have completed the following actions to correctly prepare the scaffold material for shipment back to Excel: 1) Material must be properly segregated by size & component.

4) Excel would invoice the customer for the additional charges incurred with correcting shipment 5) Excel will invoice customer for any fees and/or penalties related to improperly loaded or over loaded return shipments accessed to and paid by Excel.

4) Material must be banded to the rack insure that it will not shift or break loose, while in transit. 5) Advance copies of shipping tickets must be sent to the Excel facility in Walker, LA via fax to: - Office fax number 225-777-4159 6) Shipments must be coordinated in advance with our Excel warehouse facility in Walker, LA: - Office phone number 225-777-4157, Ext 226 7) Do not schedule material for shipment until all items have been completed.

Material shipped from the Excel warehouse facility in Walker, LA to all customers undergoes stringent quantity verification in accordance with Excel’s ISO 9001 program. All outgoing and all incoming transactions are subject to two independent verification counts. If needed, a third independent count is performed to reconcile any differences before final shipping or receipt.

All shipments to customers should be verified immediately upon receipt of the material. Any discrepancies must be reported to the Excel warehouse facility in Walker, LA immediately before any material is utilized. Excel will have 24 hours after receiving a discrepancy notice to make arrangements for an independent verification or to submit pertinent information. During this period the material must be segregated, not moved or utilized for erection, allowing Excel the ability to respond.

Section: AF-2

The goal is for all Excel material to be returned back from customers in the exact same manner in which it was initially shipped. Properly prepared Excel scaffold shipments make it much easier, safer, quicker and more accurate for all concerned parties involved in the physical inventory and return process. If for any reason the Excel scaffold material, returned by the customer is not properly prepared as requested, then Excel will take the following corrective actions: 1) Breaking down any racks or baskets of material that were improperly loaded. 2) Properly re-racking as required by our ISO-9000 Quality Assurance program. 3) Track all of the extra man hour / handling charges associated with re-racking material in order to store the components long term, awaiting future client orders and shipment.

"Key Thumb Rules To Remember When Building Excel Scaffold Towers"The purpose of adding the "Key Thumb Rule Section" to our Excel Tech Manual was to have a common place for us to collect valuable information on lessons learned and scaffold erection practices that would be useful to our end users thatare involved with the day to day construction staging stuctures that would make their work activites safer, easier and more efficent.

“SAFETY IS ALWAYS NUMBER ONE” When constructing, modifying or removing Excel scaffold material, it is very important that craft personnel handling the components in the field always wear the proper PPE safety equipment (hard hat, gloves, safety glasses and safety shoes). Leather gloves are especially important to prevent accidental hand injuries that could be caused by the positive locking trigger mechanism that are on each end of the horizontal bars which are a potential pinch point. 1) Always keep the most up to date copy of our Excel Technical Specification Manual nearby. Visit our web site where it can be down loaded as need, just go to www.excelscaffold.com 2) When constructing, modifying or removing Excel scaffold material, it is very important that craft personnel handling the components in the field always wear the proper PPE safety equipment (hard hat, gloves, safety glasses and safety shoes). Leather gloves are especially important to prevent accidental hand injuries that could be caused by the positive locking trigger mechanism that are on each end of the horizontal bars which are a potential pinch point.3) Two cup verticals cannot have an LP1(vertical pin) inserted in the top and bottom. The snap buttons will not lock on both pins and may create a drop hazard. Two cup verticals should never be used or pinned in the middle of other verticals.4) When building towers out of Excel modular material, utilize the exact same building techniques that you have always used with tube & clamp and other modular systems for bracing and board deck wrap requirements.5) Take the time during your initial job site walk down and gather the required information and measurements actually required to make a detailed and accurate Excelcut lists for pulling material.6) Do not try to memorize all of the different load ratings of Excel work decks, always refer back to the Excel technical specification manual to get the exact load ratings7) Do not try to build Excel towers in any very tight / restricted location that has been found previously to be very difficult to build with tube & clamp, it will be extremely difficult and take longer than tube & clamp.

"Key Thumb Rules To Remember When Building Excel Scaffold Towers"8) Do not use a Porta Band Saw mentality when building with Excel, modular material is typically more expensive than tube & clamp and should only be cut as a last resort, if you must cut vertical legs always cut them on the top. Keep in mind there will be invoices for damaged material.9) Always start tower erection with adjustable screw jacks. You must assume that the floor is not level. Always place screw jacks in middle of threads or approximately 6" off the ground.10) Always do a visual inspection of the horizontal bars, as the scaffold is being constructed, to make sure the triggers are properly locked in place and that they are in the up position.11) Light tapping the horizontal bars on top of the end connector is allowed to get the positive locking trigger assembly properly locked into the cups / node points on the vertical leg 12) Random field testing of Excel scaffold components by unqualified personnel is not allowed, any concerns, issues or questions with supplemental testing should always be referred to the manufacturing facility in Walker LA to the attention of Ken Hensley at 225-777-4775 Ext-223 13) Must initially use a level to get the tower totally plumb / level at the very beginning on the very first base wrap or you will fight bar placement all the way up.14) Vertical legs post are called "VP's" based on the number of cups: VP-2 is the shortest and VP-20 is the longest, always even numbers, approx. one foot in length for every two cups. Remember that VP-2's have very limited use and are only used at the very top of a vertical leg to add the final cups need to attached the top handrail, they are not used for any other application 15) Vertical cups (node point, moment connections) are on 5 3/4" centers all the way the entire vertical leg assembly for better flexibility.16) Always have two hands on the components at any one time, especially when setting 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 the upper leg while the other hand depresses the spring clip, then slowly lower the top vertical leg down. Slightly twist the vertical until the spring clip locks into place. Do not Drop the upper vertical leg onto the lower vertical leg coupling pin.18) To remove vertical legs that are connected, depress spring clip, twist (clockwise or counter clockwise) the upper vertical leg approximately 20 degrees, and with both hands, lift to remove from lower vertical leg coupling pin.

"Key Thumb Rules To Remember When Building Excel Scaffold Towers"19) All sizes of bearers and runners (Horizontal Bars) are 2" shorter than the actual size to allow for center to center measurement between vertical leg assemblies.20) 2' through 7' Excel horizontal bars are all load bearing ledgers, all other 8', 9' and 10' Excel horizontal bars are "NON" load bearing, runners only 21) You can board deck out to 8', 9' and 10' runners as long as you install 1 diagonal brace back to the leg with in 18" from the center of the runner22) Always install the telescoping diagonal bracing after the first Horizontal wrap but before the second board deck wrap is put into place.23) When passing (ie. Manual chain line) any type of telescoping brace (adjustable handrail or diagonal brace) insure components are secured together by clip prior to upward or downward movement. This applies to adjustable toe boards as well

24) Diagonal Extendable Braces (DEB's) typically require a 12 cup split between the top connector on one end and the bottom connector on the other end, eight cups between the two ends. Swivel braces (DSB's, DPB's) and Combination Braces (DCB's) may fit differently.25) Do not exceed a maximum of 14 cups (6' 6") spacing between horizontal board deck 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 from the board deck : skip two cups..hit two cups..skip two cups ..hit two cups and you will be right in line with OSHA requirements, does not require tape measure.

27) Standard hand rail corner posts are always comprised of VP-8 vertical leg assemblies (minimum eight cup leg length).28) When installing telescoping toe boards, make sure that you install the toe board end connector in the unlocked position to the vertical leg and tighten the half clamp just enough so that it won't fall off, after you have all the toe boards installed into the toe board end connector, then line everything up nice and straight and tighten up the half clamp 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 must not exceed 69"30) When adding a leg in the middle of thin air (i.e.; in the middle of a horizontal bearer bar using and IHA or on top of a side bracket or cantilever) that does not go all the way to the ground, you can not exceed 25 lbs per FT2 unless you support it back to a primary leg with a second diagonal brace.

"Key Thumb Rules To Remember When Building Excel Scaffold Towers"31) When using truss assemblies lifting rigs always insure that you use a nylon strap that is at least four inches wide or greater.32) The in line hatch is for only a light duty 25 lbs per sg ft applications only and requires a perfectly square corner for proper installation.33) When constructing the Rapid Access System (RAS), remember that once completed the work platform is limited to a light duty application of 25 lbs per sq ft34) To properly install the swing gates, rope pulley hoists and Yo Yo adapters you must always connect theses particular Excel components to the vertical leg that goes all the way to the ground for stability purposes.35) When installing vertical access ladders always remember that the ears on the Ladder bracket always points up and are installed on the ladder first and then attached to the vertical post. Additionally, you should always install the vertical ladder with the male 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 install another complete wrap or horizontal bars at least four feet above top hand rail to tie in with the rest of the tower. 37) The approved tie off area for fall protection is above the top hand rail where two horizontals bars connect to a vertical leg, refer to the tech manual for exactly how to use horizontal bars which are now approved for tie off purposes38) When installing a Yo Yo adapter above the top hand rail you must always install another entire board deck wrap at least four feet above top hand rail to tie in with the rest of tower.39) When building hanging Excel towers insure that you install safety clamp on to the vertical leg directly above the Excel horizontal bar that will be holding the weight of the leg going down.40) Always use handrails and step in the center of the treads. Always walk down the stair tower, do not run, do not skip any steps.41) Clamp Bolts should have between 40 and 65 lbs tension. Over tightening could damage the threads, bolt or item the clamp is attached to.42) Never Use RBC (Rigid Beam Clamps) or SBC (Swivel Beam Clamps) to hang or support a scaffold with the bolts. These type of clamps should only be used for bracing a scaffold or with the flat portion supporting the load.

"Key Thumb Rules To Remember When Building Excel Scaffold Towers"43) Be very careful to make sure not to overload trucks when shipping scaffold material, the maximum weight loaded should be capped at 44,000 lbs and the user should validate the estimated weight by entering the quantity of scaffold component intoa spreadsheet designed specifically to calculate and cross check the total estimated weight. (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 closest CAT certified weigh scale after they leave the job site and double check the total loaded weight so that if the truck is over weight the driver can quickly return to the site to get some material removed to lower the gross vehicle weight so that it is in compliance with the Federal DOT requirements.45) When shipping Excel scaffold material take adequate time upfront and be careful to make sure that it is always properly racked, stacked, banded prior to loading onto the flat bed trailer to prevent inadvertent shifting during transit 46) When shipping Excel scaffold material make sure to always use the proper racks and baskets. Do not make your own temporary racks out of miscellaneous scaffold parts that could come apart when loaded, unloaded or during transit which could result in 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 the flat 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 of the ratchet tie down straps. Insure that personnel do not stand below the rows of racks being 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. Scaffolds should 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 and spring are properly installed and functioning correctly. If you find an end connector with a 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 bar until you verify that it is properly locked into place and that the trigger is resting in the up position.

No other size I-Beam is authorized for trolley system use because they will not properly fit into the trolley strap kit and could cause a potential failure.52) When building lifting rigs or trolley movement systems never utilize intermediate horizontal adapters (IHA's) to hold the up the truss that will be the load bearing component. IHA’s are not designed for this purpose and they can fail and cause you to accidently drop a load if they are used improperly.

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 necessary.

Identification of damage. Employees shall be trained to recognize the following types of wear / 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 donot 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.

All material must be inspected prior to use! See Section R for inspection guidelines.

EMSLC-TSM-1001 Section: AI-2 Revised: 06/22/09

Storage: When not in use, all wood planks, should be stored above ground on dunnage to keep moisture from entering the bottom of the boards. Additionally, all boards should have some sort of lath or stickers between layers to allow for air circulation through the boards. Most important, a tarp or something as simple as a sheet of plywood should be placed over the top of the boards to prevent moisture from dropping down through the stack. Ideally, indoor storage is best

b) The inspection must be documented, dated and signed by the person performing the inspection.

3) Frequent visual examinations shall be performed weekly, (or more frequently if recommended by the designated person), while the equipment is in service. No records required.

4) A documented through inspection shall be performed any time there is reason to believe part of the lifting equipment may have been damaged during use.

Revised: 10/14/09

5) A skid pan shall not be used if it does not contain a label plate, that list the manufacturer, a serial number and the rated load.

When not in use skid pans and all associated lifting equipment shall be stored in such a way to protect the life of the equipment.

d) Deformation—any bending or twisting exceeding 10 degrees (or as recommended by the manufacturer) from the normal plane.e) Throat opening—any distortion causing an increase in the throat opening exceeding 15 percent (or as recommended by the manufacturer).f) Wear—any wear exceeding 10 percent (or as recommended by the manufacturer) of the original section dimension

Use and Inspection requirements

Skid pans are used to move scaffold material from a ground level closer to the location the material is required. This may be a higher elevation or across obstructions, such as fences, roads, streams, etc.

Skid pans come in many different sizes and shapes depending on the intended use. The following guidelines must be followed regardless of the type of skid pan used.

1). All Skid pans, cables, shackles and associated lifting equipment must be thoroughly inspected by the designated person when first delivered to the job site. The inspection must meet the requirements as defined in ASME B30.20-1.3.

a) A visual inspection must be performed by a qualified person making records of the apparent external condition to provide the basis for a continuing evaluation.
