SAFETY

STRENGTH

SUSTAINABILITY

Advances in American wood science and manufacturing technology contribute to the A PLANK advantage.Douglas-fir, a native species of north America was selected for its superior strength-to-weight ratio. Logs are

peeled to yield thin sheets of veneer. Each A PLANK Consist of multiple layers of veneer graded by strength anddensity. Naturally occurring wood defects such as knots and slope of grain are dispersed during the lay-up andlamination process for greater consistency and strength compared to solid lumber planks.

The multiple layers of thin DF veneer enhances the structural uniformity and increases the strength and reliabilityof our American made A PLANK.

Strength and Stiffness Verification

Every A Plank is individually proof tested to insure that each plank meets OSHA deflection limits before

being branded as a scaffold plank.

Modulus of Rupture and Modulus of Elasticity are frequently tested throughout the LVL production process

in accordance with the requirements of APA-EWS and independent third party inspection agency.

A PLANK is designed to conform to ANSI A10.8-2001 Loading Requirements.

Applicable Design Standards

ICBO 1997 Uniform Building Code Structural Laminated Veneer Lumber.

U.S. Occupational Safety and Health Administration, OSHA Scaffold Standards (29 CFR 1910 and 1929)

ANSI A10.8-2001, Safety Requirements for Scaffolding.

Plank Embossing

Each plank is permanently embossed with the following:

A PLANK MADE IN USA OSHA APA-EWS1081 Production Date PROOF TESTED SCAFFOLD PLANK.

Scarfed face joints for a smooth flat working surface.

Erased edges for splinter free handling.

Lightweight, yet stronger than wood, are easier to move, up or down.

Offset hoods allow for continuous run.

Plywood is held in place and edges protected by extruded aluminum side channels.

Aluminum cross channels provide additional support for plywood deck, have less flexing.

Tips on Scaffold Safety

These tips and suggestions are designed to promote safety in the use of steel scaffolding. They are intended to deal only with some of the manypractices and conditions encountered in the use of scaffolding. They do not purport to be all inclusive or to replace other additional safety andprecautionary measures to cover usual or unusual conditions. They are not intended to conflict with, or supersede any OSHA, federal, state, localstatutes or regulations.

Check Safety Codes

Check frequently with your local OSHA, state and localoffices for the latest safety code updates.

Bent or otherwise damaged frames or braces should notbe used. Put them aside for replacement or repair.

Inclement Weather

Dont work on scaffolds in bad weather or high windsunless the Competent Person decides it is OK to do so.Platforms should be cleared of ice and or snow beforebeing used.

Tie Scaffold to the Building

Scaffolding should be tied to the structure using #9 wire ortie-in devices. The first vertical tie should be at the maxi-mum height of 4 times the narrowest base dimension.Additional ties are not to exceed 26 vertically. Maximumhorizontal distance between ties is not to exceed 30.

Intermixing of Components

Scaffold frames and their components manufactured bydifferent companies shall not be intermixed, unless thecomponent parts readily fit together without force and theCompetent Person determines the resulting scaffold isstructurally sound.

Personal Safety Equipment

Anyone working on a scaffold must wear a hard hat andsteel toed work boots. Additionally, fall protection systemsmust be used when requested by the proper authorities.Scaffolding is not designed as an anchor point for fallarrest.

Dont Ride a Rolling Scaffold

The platform height of a Rolling Scaffold must not exceedfour (4) times the smallest base dimension (Cal/OSHAand some Government agencies require a stricter ratio of3 to 1) Always keep casters locked while on scaffold

Begin with Good Footings

Scaffolds must bear on base plates or screw jacks on amud sill or other adequate firm foundation.

Work Practices

Safe work practice training by a Competent Person mustbe given to workers who erect, dismantle, move, operate,repair, maintain, inspect, and use scaffolding

Dont Short Change Bracing

Use bracing at all points provided. Add extra braces ifneeded to insure stability.

Reject Damaged Parts

Guard Rails

Top Guard Rails must be installed between 36 and 45 (ifmanufactured and placed into service after Jan. 1, 2000,between 38 and 45). Mid rail is placed halfway in be-tween.

Cross Braces

Cross braces should not be used as a way to climb thescaffold. All braces must be checked for proper engage-ment onto locks. Cross bracing is acceptable for mid rail ifcross point is between 20 and 30 above the work plat-form. Cross bracing is acceptable for top rail if cross pointis between 38 and 45 above the work platform. Cross

bracing cannot serve as both.

Toe Boards

Debris and rubble should not be allowed to accumulate onthe work platform and should be removed as quickly aspossible. Additionally, tools and other materials should notbe allowed to accumulate. Toe boards should be used toprevent tools and materials from being knocked off thework platform.

Work Platforms

Use metal catwalks or platforms where available. If woodplank is used, it must be scaffold grade or better. Inspectthoroughly before each and every job to make sure it isfree from breaks, knots, cracks, or warpage. Deckageshould be full width.

Plank Overlapping

Planks 10 long or less require a 6 minimum and a 12maximum overlap. Planks greater than 10 long require a6 minimum and an 18 maximum overlap.

Protect Working Levels

Use overhead canopies to protect workers on lower worklevels when work is being done overhead. Rope off unsafeareas underneath scaffold or provide wire mesh aroundwork area.

Scaffold Training

Re-training is necessary when workers are exposed tonew hazards or conditions on the job or when workersshow signs of unsafe work practices

Dont Overload Scaffolding

Follow the safe load capacities as provided by the manu-facturer...theres a limit even to what steel can support. A4 to 1 safety factor must be calculated and maintained attimes on scaffolding.

Power Lines

DO NOT use scaffolding where the user can come intocontact with live power lines.

Inspect & Check

Take no chances. Inspect the scaffold setup after erectionand daily when in use. Dont remove or allow removal ofany parts without the OK from the Competent Person.When wire rope is used, inspect it on each job.

New OSHA Rules for Scaffolding

A) Reasons for New Rules

1. 9% of all construction fatalities occurred Scaffolding2. There have been 510,500 injuries and 9,750 reported

deaths.3. 72% of injuries involved planking and supports.4. 25% of people on jobs received no training on Scaffolding.5. Only 33% of inspected Scaffolding have guard rails.

C) Key Definitions

B) Objectives

1. Dont let the scaffold fall.2. Dont fall off the scaffold.3. Dont let the material fall off the scaffold.

1. Competent Person: means one who is capable of indentifying existingand predictable hazards in the surroundings or working conditions whichare unsanitary, hazardous or dangerous to employees, and who hasauthorization to take prompt corrective measures to eliminate them.

2. Qualified Person: means one who, by possession of a recognizeddegree, certificate, or professional standing, or who by extensiveknowledge, training, and experience, has successfully demonstratedHis/her ability to solve or resolve problems related to the subject mater,the work or the project.

Name of Competent Person

Name of Qualified Person

D) Significant Changes to Subpart L

1. Fall protection for Erectors and Dismantlers: The new standard now requires employees be protected from falls whileerecting (including increasing the height of the scaffold as the work progresses). The employers must conduct a feasibil-ity study to determine when fall protection, such as personal fall protection systems, are feasible and do not create agreater hazard. (Scaffolding is not designed as an anchor point for fall arrest).

2. Electrical Shock Protection: The new standard requires safe distance from power lines be maintained as outlined in thestandard.

3. Employee Training: The new 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 the scaffold.4. Daily Inspections: The new standard requires the scaffold be inspected before each use, daily or before each work shift

by a competent person.5. Welding from a Suspended Scaffold: The new standard requires specific precaution be taken when welding from a

suspended scaffold to prevent current travel and/or arcing in the scaffold components.6. Cross Braces as Railings: The new standard specifically addresses under what circumstances a cross brace can sub-

stitute 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.

Codes of Safe PracticesFor Frame Scaffolds, System Scaffolds, Tube and Clamp Scaffolds, and Rolling Towers

1. General Guidelinesa) Post this 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, andother hazardous conditions created by other trades. These conditions shall becorrected or avoided as noted in the following sections.

d) Inspect all equipment before using. Never use any equipment that is damaged ordefective in anyway. Remove it from the j ob site.

e) Scaffolds must be erected in accordance with design and or manufacturersrecommendations.

f) Do not erect, dismantle or alter a scaffold unless under the supervision of a qualifiedperson.

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 a safe condition. Report any unsafe condition to your supervisor.i) Never take chances! If in doubt regarding the safety or use of 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.

2. Guidelines for Erection and Use of Scaffolds

a) Scaffolds base must be set on adequate sill or pad to prevent slipping or sinkingand fixed thereto where required. Any part of a building or structure used to supportthe scaffold shall be capable of supporting the m aximum load to be applied.

b) Use adjusting screws or other approved methods instead of blocking to adjust touneven grade conditions.

c) Bracing, Leveling & Plumbing of Frame Scaffolds.1. Plumb and level all scaffolds as the erection proceeds. Do not force fr ames

or braces to fit. Level the scaffold until proper fit can easily be made.2. Each frame or panel shall be braced by horizontal bracing, cross bracing,cross bracing diagonal bracing or any combination thereof for securingvertical members together laterally. All brace connections shall be m adesecure, in accordance with t he manufacturers recommendations.

d) Bracing, Leveling & Plumbing of Tube & Clamp and Systems 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 f easible. The distancebetween bearers and runners shall not exceed manufacturers recommendedprocedures.

2. Plumb, level and ti e 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) scaffold to the wall or structure at each end and at least every

30 of length when scaffold height exceeds the maximum allowable free standingdimension.

Begin ties or stabilizers when the scaffold height exceeds that dimension and repeat atvertical intervals not greater than 26. The top anchor shall be placed not lower than four(4) times the base dimension from the top of t he completed scaffold. Anchors mustprevent scaffold from tipping into or away from wall or structure. Stabilize circular orirregular scaffolds in such a manner t hat completed scaffold is secure and restrainedfrom tipping.When scaffolds are partially or fully enclosed or subjected to overturning loads, specificprecautions shall be taken to insure the fr equency and accuracy of ties to the wall andstructure. Due to increased loads resulting from wind or overturning loads the scaffoldingcomponent to which ties are subject shall be checked for additional loads.

f) When free standing scaffold towers exceed four (4) times their minimum base dimension

vertically, they must be sustained from t ipping (CAL OSHA and some governmentagencies require stricter ratio of 3 to 1.

g) Do not erect scaffold near electrical power lines unless proper precautions are taken.Consult the power service company f or advise.

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 guard rails 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 Scaffold shall be installed and used in accordance withmanufacturers r ecommendations.

2. Brackets for Frame Scaffolds shall be seated correctly with side bracketparallel to the f rames and end brackets at 90 degrees to the f rames. Bracketsshall not be bent or twisted from normal position. Brackets (except mobilebrackets 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 accordancewith manufacturers recommendations.

l) All scaffolding components shall be installed and used in accordance with the manu-facturers recommended procedure. Components shall not be altered in the field.Scaffold frames and their components manufactured by different companies shall not beintermixed, unless the component parts readily fit together and the resulting scaffoldsstructural integrity is maintained by the user.

m) Planking1. Work platforms shall cover scaffold bearer as completely as possible. Only

scaffold grade wood planking, or fabricated planking and decking meetingscaffold use requirements shall be used.

2. Check each plank prior to use to be sure plank i s not warped, damaged, orotherwise unsafe.

3. Planking shall have at l east 12 overlap and extend 6 beyond center ofsupport, or be cleated or restrained at both ends to prevent sliding off supports.

4. Solid sawn lumber, LVL (laminated veneer lumber) or fabricated scaffoldplanks and platforms (unless cleated or restrained) shall extend over their endsupports not less than 6 nor more than 18. This overhang should not beused 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 extend at least 6 beyond the point of support.3. Place proper bracing between putlog/truss when the span of the putlog/truss

is more than 12.o) For Rolling Scaffolds, the following additional guidelines apply.

1. Riding the rolling tower is very hazardous. THE SCAFFOLD INDUSTRYASSOCIATION DOES NOT RECOMMEND NOR ENCOURAGE THISPRACTICE. 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 adjusting screwby pins or other suitable means.

3. No more than 12 of the screw jack shall extend between the bottom of theadjusting nut and the top of the caster.

4. Wheels or casters shall be provided with the locking means to prevent casterrotation and scaffold movement and kept locked.

5. Joints shall be restrained from separation.6. Use horizontal, diagonal bracing near the bottom and at 20 intervals measured

from the rolling surface.7. Do not use brackets or other platform extensions without compensating for the

the overturning effect.8. The platform height of a rolling scaffold must not exceed 4 times the smallest

base dimension. (CAL OSHA and some government agencies require a ratioof 3 to 1).

9. Cleat or secure all planks.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 the floor or 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 safeworking condition.

2. Erected scaffolds and platforms should be inspected continuously by thoseusing them.

3. Exercise caution when entering or leaving work platform.4. Do not overload scaffold. Follow m anufacturers safe working load recommend-

ations.5. Do not jump on to planks or platforms.6. Do not use ladders or make shift devices on top of working platforms to

increase the height or to provide access from above.7. Climb in access areas only and use both hands.

3. When Dismantling Scaffolding the Following Additional Guidelines Apply:a) Check to insure that the scaffolding has not be structurally altered in a way in which

would make it unsafe, and if it has, reconstruct where necessary before commencing withdismantling procedures. This includes all scaffold types.

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 with 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 the scaffold.g) Dismantled equipment should be stock piled in an orderly manner.h) Follow erection procedures and use manuals.

These safety guidelines (Code of Safe Practice) set f orth common sense procedures for safely erecting, dismantling and using scaffold equipment. However, equipment and scaffolding systems differ, andaccordingly, reference must always be made to the instructions and procedures of the supplier and or manufacturer of t he equipment. Since field conditions vary and are beyond the control of the ScaffoldIndustry Association, safe and proper use of scaffolding is t he sole responsibility of the user.
