Overview
This video explains the technical standards and guidelines for scaffolding (perancah) in construction, emphasizing safety and proper procedures. It covers the objectives of learning about scaffolding safety, common accidents and their causes, relevant regulations and standards, and detailed requirements for various types of scaffolding, including their components, materials, and installation. The video also addresses the safe use of ladders and stairs, as well as the importance of proper foundation and base support for scaffolding structures to prevent collapses and ensure worker safety.

Chapters
- The primary goal is to understand and apply safety standards and technical guidelines for scaffolding.
- Learners should be able to plan, select, erect, use, dismantle, and store scaffolding safely and correctly.
- Key objectives include preventing unsafe actions and conditions, and understanding accident causes if they occur.
Understanding these objectives ensures that scaffolding work is conducted with a focus on preventing accidents and protecting workers.
The video mentions that understanding these standards helps in preventing accidents like falls or material collapses.
- Common accidents include falls from scaffolding, falling objects, and scaffolding collapse.
- Electrical shock is also a significant hazard if workers are not cautious around live electrical sources.
- Statistics show that scaffolding collapse is a major cause of fatalities in scaffolding-related accidents.
Recognizing these common accidents and their severity highlights the critical need for strict adherence to safety protocols.
Examples of accidents cited include four workers dying in a bridge collapse and 12 fatalities in a building collapse in Samarinda.
- Scaffolding is a temporary structure assembled on-site to provide a safe working platform at height.
- It is not permanent and must be erected and used according to specific procedures by authorized personnel.
- Relevant regulations include Law No. 1 of 1970 on Work Safety and ministerial decrees concerning safety in construction activities.
Knowing the definition and regulatory basis provides the legal and procedural foundation for all scaffolding operations.
The video references specific regulations like Permenaker No. 11/MEN/1986 and Kepmen PU No. 114/KPTS/1986.
- Evaluate and calculate loads to select the appropriate scaffolding type.
- Ensure the ground foundation is strong and stable, and the scaffolding structure is robust.
- Use trained and competent personnel for erecting and dismantling scaffolding.
- Verify all components are in good condition and properly installed.
- Conduct hazard identification, risk assessment, and implement control measures, including the use of Personal Protective Equipment (PPE).
These steps are crucial for ensuring the structural integrity and safety of the scaffolding system before and during use.
This includes checking that components like the base plates, standards, ledgers, and braces are correctly installed and in good condition.
- Suspended scaffolding (gondolas) require strong anchor points, safety cables, and daily checks.
- Cantilevered scaffolding (trigger/tubular) is for specific trades like carpentry or painting and not for heavy materials.
- Various types exist, including pole scaffolds, mobile scaffolds, and window scaffolds, each with specific usage limitations and safety requirements.
- Tube and coupler scaffolding requires strong connections and protection against rust, while mobile scaffolds must have wheels locked during use.
Understanding the different types of scaffolding and their specific limitations prevents misuse and ensures they are appropriate for the intended task.
The video shows a suspended scaffolding (gondola) used for window cleaning on high-rise buildings.
- Scaffolding platforms must be strong, have toe boards, and guardrails (handrails) if over two meters high.
- Guardrails typically consist of a top rail, mid-rail, and toe board.
- Access to scaffolding should be safe, often via ladders, and loads must be managed to prevent falls.
- Work platforms must be kept clear of debris, and tools should be secured to prevent falling.
These features are direct safety measures designed to prevent workers and materials from falling off the scaffolding.
A guardrail system is described with specific heights for the top rail, mid-rail, and toe board.
- Scaffolding materials can be metal pipes (steel/aluminum), wood, or bamboo, each with specific quality requirements.
- Metal pipes must be straight, free from deformation, and protected from rust.
- Wood must be straight, strong, dry, and free from large knots or rot.
- Connections (couplers, pins, ropes) must be strong, durable, and appropriate for the material and load.
The quality and integrity of the materials and their connections directly determine the overall strength and stability of the scaffolding.
The video shows different types of couplers used for connecting metal scaffolding pipes, including swivel and fixed couplers.
- Ladders must be strong, well-maintained, and used correctly to ensure worker safety.
- Portable ladders should not exceed six meters in length, and extension ladders should not exceed fifteen meters.
- Fixed ladders over eight meters require safety devices like fall arrest systems or rest platforms.
- Ladders should be placed at a safe angle (approximately 75 degrees or a 1:4 ratio of horizontal to vertical distance) and secured.
Safe use of ladders and stairs is essential as they are common access points and potential sources of falls if not properly managed.
The video illustrates the correct angle for leaning a ladder against a wall using the 1:4 ratio.
- Scaffolding foundations must be strong enough to support the load and distribute it to the ground.
- Base plates are recommended to spread the load, especially on softer ground.
- Uneven ground must be leveled, and appropriate timber or concrete pads used for support.
- The working platform must be level, with toe boards and safe access provided.
A stable foundation is the bedrock of scaffolding safety; any weakness here can lead to catastrophic failure.
For soft ground, a wooden board with dimensions of at least 40x25 cm and a thickness of 30-35 mm is recommended as a base plate.
Key takeaways
- Scaffolding is a temporary structure requiring strict adherence to safety standards to prevent severe accidents like falls and collapses.
- Understanding relevant laws and regulations is the first step in ensuring safe scaffolding practices.
- Thorough planning, including load calculation and hazard assessment, is critical before erecting any scaffolding.
- Only trained and competent personnel should be involved in the erection, use, and dismantling of scaffolding.
- Different types of scaffolding have specific applications and limitations that must be respected.
- Essential safety features like guardrails, toe boards, and secure platforms are non-negotiable for worker protection.
- The integrity of scaffolding materials and their connections is paramount to its stability.
- Safe practices for ladders and stairs, including proper angle, securing, and load limits, are vital for access safety.
