The aim and objective of safety procedure applied for scaffold structure and the manpower working on the site is to provide the mandatory requirements and safe practices necessary for scaffold erection, modification, dismantling, use and storage. This Procedure should be used in conjunction with recommended requirements under regulations of Saudi Administration, and other Middle East countries generally based on OSHA, Saudi Aramco andAdnoc, Enoc, UAE guidelines which help to achieve safe scaffold erection and use. This safety procedure must be followed to all operating and project sites of construction companies in Saudi Arabia, Dubai, Oman and Arabian Spar is well known for this safety procedures application in its scaffolding projects throughout the Middle East. The results expected from the application of this scaffold safety procedures are:
- To manage scaffold erection,
- To use and dismantling job safely,
- Control of unwanted incidents related to scaffold erection, use and dismantling work,
- Compliance to regulatory requirements of government related to Scaffolds, and
- To provide safe scaffolding platform for jobs to be done at height for any construction project.
The above expected scaffold safety result can be guaranteed only when standard quality marked scaffolding products and services are used in scaffolding work, such as the most reliable and tested Arabian Spar scaffolding Pipes & Tubes, Cuplock Systems, Ringlock Systems, Tube and Fittings, Scaffolding Steel Boards/Plank, Ladder & Lattice Beams, couplers or frames, scaffold metal deck and other materials used to assemble for building a scaffold in construction industries and oil refineries for health and safety purposes of manpower.
The other most important safety procedural requirements for scaffold is application of the quality and approved scaffolding services provided for erecting, altering or dismantling a temporary scaffolds platform to support construction workers from which a person or object can fall more than 4 meters from there. This scaffolding work must be provided by an authentic and government approved scaffolding product and service supplier under the supervision of a person, i.e. supervisor or engineer holding the appropriate class of high-risk work license from an authorized institution. Arabian Spar is known for quality supply of scaffolding services, such as Contract Scaffolding Services, Hire and Sales, Design, Manpower/Training… in KSA, Dubai, Abu Dhabi, Oman, Qatar and other MENA countries.

Scaffold Safety Procedure General Information
1. Erection, Dismantlement, Movement, and Modification
Approved Permit-To-Work (PTW) and Job Safety Analysis (JSA) shall be made available before erecting, dismantling, moving, or modifying scaffolding. Examples of hazards to consider include, but not limited to the following:
- Working from heights
- The presence of nearby electrical lines or process equipment
- Hazardous area classification
- The condition of working surfaces
- The presence and activity of other people in the vicinity of the work
- The weather (Heavy rain, high wind velocity-more than 36 Km/Hr, etc.)
- Scaffolding shall be erected, dismantled, moved, and modified only under the direction of a competent person and by employees who have received appropriate and specific training for the work they are to perform. Determination and designation of competent persons for scaffold work are the responsibility of the site except where local regulations set other criteria.
3. Categories and Classification
Most scaffolds fall into one of the four primary categories:
- Tube and coupler scaffold/Coup lock scaffold
- Suspended scaffold
- Mobile scaffold
- System scaffold
- Supported scaffold
- Scaffolds are classified according to their intended use as:
- Light duty
- Medium duty
- Heavy duty
|Maximum Safe load in Kg/M²||75||150||225||300||450||600|
|Maximum bay length in meter||2.7||2.2||1.8||1.4||1.0||0.8|
4. Specifications of Scaffolds applicable to all Scaffolds
- All elevated structures/ working platform areas shall be guarded on all sides.
- Railings and toe boards shall be provided on the platform.
- Scaffolds shall be designed to support at least 4 times the anticipated weight of Men and material.
- Make certain that all scaffolds are in plumb and level at all times.
- Scaffolds shall be secured from tipping when the scaffold height exceeds four times its minimum base dimension.
- Scaffolds shall be constructed at least 2 planks wide unless location makes this physically impossible.
- The scaffolding width is determined by the width of the boards, the minimum width allowed for two boards is 600 mm but a more typical four-board scaffold would be 870 mm wide from standard to standard. More heavy-duty scaffolding can require 5, 6 or even up to 8 boards width
- Landing platform shall be provided at every 9 meter of height.
- The members of scaffolds shall overhang not less than 6″ on either ends but not more than 12″. They shall be fastened on both ends and laid tight by scaffolds and clamps.
5. Specifications of Scaffolds applicable to Tube-and-Coupler Scaffold
- Minimum height of first horizontal member (Ledger) of scaffolds from the Ground/Kicker lift member shall be 2.2 meters. When scaffold is more than 6 meters height or carrying heavy load, kicker lift should be provided.
- The mid rail and Top rail shall be at height 600 mm and 1200 mm respectively and toe boards (150mm) shall be securely attached to the platform.
- Wall scaffoldings shall be secured between structure and scaffolding, at least every 10 meters of length and 8 meters of height.
- Minimum overlap of vertical members (standards) and/ or horizontal members (Ledgers) shall be 600 mm with at least two couplers.
- Base plate 100 x 100 x 3 mm shall be used to support all vertical pipes of Scaffolds.
- Sole plate of 300 x 300 x 6 mm shall be used at all unpaved area to support base plate.
6. Precautions applicable to Mobile Scaffold
- Attach castors with plain stems to the panel or adjustment screw by pins or other suitable means. Mid rail and Top rail shall be at height 600mm and 1200 mm respectively.
- Apply castor brakes at all times when a scaffold is not being moved.
- Do not ride rolling scaffoldings.
- Remove all material and equipment from platform before moving scaffolding.
- Do not try to move rolling scaffolding without sufficient help. Watch out for holes in the floor and for overhead obstructions.
- Do not use brackets on rolling scaffoldings without first considering the overturning effect.
- Mobile Scaffolds shall be designed to restrict maximum height verses length to 4:1.
Do’s and Don’ts for Scaffold Safety
- Use only certified scaffolding, tagged with “Scaffolding Complete, Ready for Use” like Arabian Spar Scaffoldings.
- Maintain three-point-contact while climbing up or down the ladder.
- Use rope or container or other suitable means for carrying material from or to ground.
- Maintain good housekeeping, especially at elevated working platform and near the access.
- Do take special precautions while working in vicinity of mobile cranes or electrical overhead lines.
- Wear full body Arabian Spar safety harness with double lanyard/ personal fall arrest system or other equally effective means while ascending or descending the ladder or scaffolding working platform is not fully guarded.
- Do check for emergency approach/ evacuation, especially adequacy means of egress.
- Use safe Spar scaffolding material handling ways while shifting the material.
- Do report “At-risk conditions” e.g. missing ladder, incomplete decking, improper guarding, no landing platform, loosely clamped ladder, etc. to your supervisor.
- Do check weekly certification of scaffold at random.
- Do not use any part of operational line or pressurized piping as a support, or tie point for scaffolds or staging.
- Do not permit mixing of scaffold types in any one structure (e.g., steel/aluminum couplers, wooden boards/metal grid boards).
- During the possibility of a thunderstorm, no work shall be executed at a height where a person can be exposed to lightning and heavy storms.
- Never keep loose tools, materials, etc. at height in a way it may roll off and fall from height.
- Do not use cross-bracing or end-frame (unless specially designed) for access.
- Avoid overloading and impact loading
- Never alter or modify or dismantle any part of the scaffold without permission from scaffolding supervisor or Arabian Spar personnel.
