INTRODUCTIONThe Excel Scaffold Custom/Specialty Manual contains components not found in the Excel Standard ComponentTechnical Manual. This is a supplemental manual to be used in conjunction with the standard manual.All components found in this manual fall under the same standards and conditions found in the StandardComponent Technical Manual.Some items found in the Custom/Specialty Manual are for sale only, or take additional lead time tomanufacture. Please ensure of the availability of components prior to ordering.This manual does not replace the OSHA 1926/1910 and/or CAL-OSHA documents.1. Compatibility of Excel Modular Scaffold:Excel scaffold is designed and engineered to be compatible with standard tube & clamp components (i.e.: clamps,poles, ladders and ladder brackets) that are currently available within the scaffold industry. These tube & clampcomponents are generally used for: Tube & clamp for tie-offs when needed for seismic considerationsWhen needed to transition horizontally to get around obstaclesWhen needed to transition vertically to get around interferenceLadders and ladder brackets for access to work platformsAs 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 & 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 personnel withadequate supervision.Excel expects all users to provide supervision that is competent and qualified, and who can inspect and sign off on eachscaffold 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 of proper PPE, weight-loading restrictions, vertical leg placement, use of diagonal bracing, horizontalwraps, proper use of handrails, mid-rails, 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, asrequired 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 andinstalling these items.Ensure 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 of the Standard Component Technical Manual forInspection guidelines.EMSLC-TSM-1001Page iiRevised: 12/03/16
INTENDED USE OFEXCEL 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 for downward or compressive loading only.3. Excel’s scaffold material, when constructed for normal use, is not designed to be up- or side-loaded in excess of OSHAand ANSI requirements. When conditions require special loading, extra design features must be added to ensure properstability.4. Once installed and completed, scaffold should be considered part of the customers plant equipment. Abuse or mistreatmentof 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 thescaffold material such as: The scaffold comes into contact with any moving equipment, forklifts, trucks or trailers, and other types of mobileequipment. The scaffold is affected by an unintended load, flanges or piping attached to a crane or come-along, objects droppedfrom above or swung in from the side, etc. Excessive force is applied to the scaffold from abuse or accidental contact. The material is modified in any way with a torch, saw or other equipment. The material is affected from corrosive chemicals that remove the coating and/or damage the base metal. The material is bent or otherwise damaged.6. The end-user should ensure that their competent, qualified individuals and scaffold erection personnel are trained and fullyunderstand the above requirements.7. When testing of material is required, it should be conducted by qualified personnel in a testing environment. Field testing ofscaffold 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 fortraining. New users should examine the Key Rules at the end of the manual.9. OSHA requires that inspections must be made by the scaffold builder and end-user.All material must be inspected prior to use!
