Scaffolding
- Q: What are the key safety features of scaffolding?
- A: Secure footing, guardrails, proper design for weight load, and stable platforms.
- Q: What is the purpose of guardrails on scaffolding?
- A: Guardrails prevent workers from falling off scaffolding by providing a barrier at the edges.
- Q: Who is responsible for inspecting scaffolding?
- A: A qualified person, such as a scaffold inspector, should inspect scaffolding before use and periodically during its use.
- Q: How often should scaffolding be inspected?
- A: Scaffolding should be inspected before each use and after any significant changes, such as weather conditions or alterations to the scaffold.
- Q: What should be done if scaffolding is found to be unsafe?

Training and Competency
- Q: Who should be trained for work at height?
- A: All workers who perform work at height, including supervisors and managers, should receive proper training in safety procedures and equipment use.
- Q: What should be covered in work-at-height safety training?
- A: Training should include hazard identification, use of fall protection, safe use of ladders and scaffolding, and emergency procedures.
- Q: How often should work-at-height safety training be conducted?
- A: Safety training should be provided upon hiring, when there are changes in procedures, and periodically to ensure ongoing competency.
- Q: Can workers without specific training be allowed to work at height?
- A: No, only trained and competent workers should be allowed to perform work at height to ensure safety.
- Q: What is the role of supervisors in work-at-height safety?
- A: Supervisors ensure that safety procedures are followed, that workers are trained, and that proper fall protection equipment is in place.
Weather and Environmental Considerations

- A: Weather conditions such as rain, snow, high winds, and ice can increase the risk of slips, falls, and accidents while working at height.
- Q: When should work at height be postponed due to weather?
- A: Work should be postponed during adverse weather conditions that make the task unsafe, such as strong winds or slippery surfaces.
- Q: What measures should be taken to protect workers from high winds while working at height?
- A: Workers should be secured with fall protection, avoid working on high platforms during high winds, and ensure equipment is stable.
- Q: How should snow and ice be handled when working at height?
- A: Snow and ice should be removed from platforms and ladders before work begins, and workers should wear slip-resistant footwear.
- Q: What is the maximum wind speed for working at height?
- A: Wind speed limits can vary by local regulations and specific work conditions, but work should generally be avoided if wind speeds exceed 25 mph (40 km/h).
Fall Arrest Systems
- Q: What components are included in a fall arrest system?
- A: A fall arrest system includes a harness, lanyard, anchorage point, and shock absorber.
- Q: How do you ensure that fall arrest equipment is properly fitted?
- A: The harness should fit snugly but comfortably, with all straps adjusted correctly, and the lanyard should be securely attached to a stable anchor point.
- Q: What is a lifeline used for in fall arrest systems?
- A: A lifeline is a rope or cable that workers are attached to in order to prevent falls, typically used when working at greater heights.
- Q: What should be done if a fall arrest system is involved in a fall?
