Statutory and regulatory framework
Statutory and regulatory framework is the domain that tests whether you can name the legal duties behind a truss-out scaffold and apply them to real site decisions.
The statutory chain
- The Factories and Industrial Undertakings Ordinance (Cap. 59) imposes general duties on proprietors and contractors to provide a safe workplace, safe plant and a safe system of work; workers must cooperate and use safety equipment.
- The Construction Sites (Safety) Regulations (Cap. 59A) contain scaffold-specific duties: sound construction, adequate strength, competent erection and supervision, safe access, inspection before use, periodic inspection (normally at least every 14 days), and inspection after alteration, damage or weather likely to affect stability.
- The Construction Workers Registration Ordinance (Cap. 583) requires registered construction workers for designated trades. Scaffolders also need the mandatory basic safety training certificate, commonly called the Green Card.
- Labour Department codes of practice, including the Code of Practice for Metal Scaffolding Safety, are not statutes but are strong evidence of what is reasonably practicable.
How the duties interlock
A contractor cannot transfer its duty by hiring a subcontractor. The subcontractor must plan, supervise and resource the work; the competent person inspects and confirms; the individual scaffolder must follow the design, use PPE and stop work if the scaffold is unsafe. The client or property owner also controls access and must disclose known facade hazards.
Worked example
A property manager asks a subcontractor to add a 2 m truss-out platform above a busy shop. The subcontractor says a green tag from another scaffold is enough. Correct reasoning: the new platform is an alteration, so it needs a design check, competent-person inspection and a new tag before loading. The contractor still owns the duty to provide a safe system and public protection. A tag from a different scaffold proves nothing.
Traps
Do not treat a code as optional or as law; use it as the benchmark. Do not confuse the competent person who inspects with the registered scaffolder who erects. Do not assume a 14-day inspection replaces the pre-use check after storms, impact or alteration.
