OSHA Rules For ScaffoldingOSHA Rules For Scaffolding

OSHA Rules for ScaffoldingA)Objectives:Name of Competent Person:1. Don’t let the scaffold fall.2. Don’t fall off the scaffold.3. Don’t let the material falloff the scaffold.Name of Qualified Person:B)Key Definitions:1. Competent Person: means one who is capable of identifying existing and predictable hazards in thesurroundings or working conditions which are unsanitary, hazardous or dangerous to employees, and whohas authorization to take prompt corrective measures to eliminate them.2. Qualified Person: means one who, by possession of a recognized degree, certificate, or professionalstanding, or who by extensive knowledge, training and experience, has successfully demonstrated his/herability to solve or resolve problems related to the subject matter, the work or the project.C)Significant Changes to Subpart L*1. Fall protection for Erectors and Dismantlers: The standard now requires employees be protected from fallswhile erecting (including increasing the height of the scaffold as the work progresses). The employers mustconduct a feasibility study to determine when fall protection, such as personal fall protection systems, arefeasible and do not create a greater hazard. (Scaffolding is not designed as an anchor point for fall arrest.)2. Electrical Shock Protection: The standard requires safe distance from power lines be maintained as outlinedin the standard.3. Employee Training: The standard now specifically requires all employees who work on, erect or dismantle,repair, operate, maintain or inspect scaffolding be trained in specific areas related to the safe use of thescaffold.4. Daily Inspections: The new standard requires the scaffold be inspected before each use, daily or before eachwork shift by a competent person.5. Welding from a Suspended Scaffold: The standard requires specific precaution be taken when welding froma suspended scaffold to prevent current travel and/or arcing in the scaffold components.6. Cross Braces as Railings: The standard specifically addresses under what circumstances a cross brace cansubstitute as a top or mid rail (not both).7. Access: The standard now defines how and under what circumstances a ladder or steps will be used.Load ChartFrameTier 1Tier 2Tier 3Tier 4Part(all weights are in lbs. per leg)Load(all weights are in lbs.)5’ x 3’ SLBAll Purpose42003465336029931000 evenly distributed5’ x 4’ SLBScrew Jack420034653360299311000 at top of jack5’ x 5’ SLB20” Side Bracket4043336032132835500 personnel only5’ x 6’ 6” SLB7’ Plywood Deck244122402048178575 per sq. ft. with 1/2” decking5’ x 6’ 6” WTFolding Trestle34343045264623731000 on top cross memeber5’ x 6’ 4” WT8” Caster3434304526462373500 per casterFor towers exceeding four (4) tiers high, subtract dead load weight/leg of frames, crossbraces, and brackets above the 4th tierto obtain an allowable load/leg for workman, materials, and planking.All values are based upon 12” maximum screw extension at the base of the scaffold.* Subpart L is the OSHA Scaffolding standard and can be obtained from your local OSHA office.

ld SaTipsfetyTips on ScaffoScaffoldSafetyThese tips and suggestions are designed to promote safety in the use of steel scaffolding. They are intended to deal only with someof the many practices and conditions encountered in the use of scaffolding. They do not purport to be all inclusive or to replaceother additional safety and precautionary measures to cover usual, or unusual conditions. They are not intended to conflict with, orsupersede any OSHA, federal, state, local statues or regulations.Check Safety CodesGuardrailsCheck frequently with your local OSHA, stateand local offices for the latest safety code updates.You can also check the A1 web site atwww.a1scaffold.com for code updates and thelatest in scaffold safety tips.Top guard rails must be installed between 36” and45” (if manufactured and placed into service afterJan. 1, 2000, between 38” and 45”). Mid rail isplaced halfway in between.Cross BracesDon’t Short Change BracingUse bracing at all points provided. Add extrabraces if needed to insure stability.hea fe t y Codck SesBent or otherwise damaged frames or bracesshould not be used. Put them aside forreplacement or repair. For repair, call A1 Plank &Scaffold.CReject Damaged PartsCross Braces should not be used as a way to climbthe scaffold. All braces must be checked forproper engagement onto locks. Cross bracing isacceptable for mid rail if cross point is between20” and 30” above the work platform. Crossbracing is acceptable for top rail if cross point isbetween 38” and 45” above the work platform.Cross bracing cannot serve as both.oss BracesCrInclement WeatherToeboardsDebris and rubble should not be allowed toaccumulate on the work platform and should beremoved as quickly as possible. Additionally,tools and other materials should not be allowed toaccumulate. Toeboards should be used to preventtools and materials from being knocked off thework platform.Don’t work on scaffolds in bad weather or highwinds unless the Competent Person decides it isOK to do so. Platforms should be cleared of iceand or snow before being used.Tie Scaffold to the BuildingScaffolding should be tied to the structure using#9 wire or tie-in devices. The first vertical tieshould be at the maximum height of 4 times thenarrowest base dimension. Additional ties are notto exceed 26’ vertically. Maximum horizontaldistance between ties is not to exceed 30’.wer LinesPoWork PlatformsIntermixing of ComponentsScScaffold frames and their componentsmanufactured by different companies shall not beintermixed, unless the component parts readily fittogether without force and the Competent Persondetermines the resulting scaffold is structurallysound.Inst and ChecpecProtect Working LevelsUse overhead canopies to protect workers onlower work levels when work is being doneoverhead. Rope off unsafe areas underneathscaffold or provide wire mesh around work area.kODon’t Ride a Rolling Scaffoldloverad ScaffoldThe platform height of a rolling scaffold must notexceed four (4) times the smallest base dimension(Cal/OSHA and some Government agenciesrequire a stricter ratio of 3 to 1)Don’t Overload Scaffoldingl d t o BuaffoildRe-training is necessary when workers areexposed to new hazards or conditions on the job orwhen workers show signs of unsafe workpractices.ent WeathelemcnrScaffold TrainingIWork PracticesSafe work practice training by a CompetentPerson must be given to workers who erect,dismantle, move, operate, repair, maintain,inspect, and use scaffolding.Guyed ScaffoldsgTieScinScaffolds must bear on base plates or screwjackson a mud sill or other adequate firm foundation.Proper UsageNever use equipment for purposes other thanthose recommended by A1 Scaffold Mfg., Inc.Contact A1 for further information.Follow the safe load capacities as provided by themanufacturer. there’s a limit even to what steelcan support. A 4 to 1 safety factor must becalculated and maintained at all times onscaffolding.Always keep casters locked while on scaffold.Begin with Good FootingsPlank OverlappingPlanks 10’ long or less require a 6” minimum anda 12” maximum overlap. Planks greater than 10’long require a 6” minimum and a 18” maximumoverlap.Personal Safety EquipmentAnyone working on a scaffold must wear a hardhat and steel toed work boots. Additionally, fallprotection systems must be used when requestedby the proper authorities. Scaffolding is notdesigned as an anchor point for fall arrest.old TraininaffgUse metal catwalks or platforms where available.If wood plank is used, it must be scaffold grade orbetter. Inspect thoroughly before each and everyjob to make sure it is free from breaks, knots,cracks or warpage. Decking should be full width.Remember - Slack guys are useless. Overtautguys are dangerous.Power LinesDO NOT use scaffolding where the user can comeinto contact with live power lines.Inspect & CheckTake no chances. Inspect the scaffold setup aftererection and daily when in use. Don’t remove orallow removal of any parts without the OK fromthe Competent Person. When wire rope is used,inspect it on each job.
