- Q: What should be done if a scaffold fails an inspection?
- A: The scaffold should be tagged as unsafe, workers should be kept off, and necessary repairs should be made before it can be used again.
- Q: How should scaffolding components be maintained?
- A: Scaffolding components should be regularly cleaned, checked for wear or damage, and replaced when necessary to ensure safe use.
Working on Scaffolding
- Q: What is the maximum safe load for scaffolding?
- A: The maximum load capacity should be specified by the manufacturer or the scaffold designer and must not be exceeded. The load includes both the weight of workers and materials.
- Q: How should materials be stored on scaffolding?
- A: Materials should be stored evenly, kept away from edges, and not overloaded. Heavy materials should be stored at lower levels to avoid imbalance.
- Q: Can workers climb scaffolding without guardrails or ladders?
- A: No, workers should not climb scaffolding without proper access points such as ladders or stairways, and guardrails should be in place for safety.
- Q: Is it safe to stand on the top platform of a scaffold?
- A: No, workers should avoid standing on the top platform unless it is a designed and stable working platform, and there should be guardrails to prevent falls.
- Q: What should workers do to prevent falling from scaffolding?
- A: Workers should always use fall protection, maintain three points of contact, avoid leaning over the edges, and ensure guardrails and toeboards are in place.
Scaffold Types and Uses
- Q: What is the difference between supported and suspended scaffolding?
- A: Supported scaffolding is supported by the ground or a structure, while suspended scaffolding is suspended from a structure using ropes or cables.
- Q: What is modular scaffolding?
- A: Modular scaffolding is pre-engineered and assembled from standardized components, offering flexibility for a wide range of construction activities.
- Q: What type of scaffolding is suitable for maintenance work on a tall building?
- A: Suspended scaffolding is often used for maintenance on tall buildings because it can be adjusted in height easily.
