HK Truss-out Scaffolder (CIC) study guide
HK Truss-out Scaffolder (CIC) · Work through your exam, one topic at a time.
The Hong Kong Truss-out Scaffolder credential is the trade-level recognition for workers who erect, alter and dismantle the small cantilevered scaffolds that hang off a building facade - the bamboo or metal brackets that let a crew repair a window, fix a drainpipe or render a wall without full scaffolding. It is aimed at experienced bamboo scaffolders and construction workers moving into facade repair work, and at anyone who needs to show an employer or a site supervisor that they can build a truss-out safely. The HK Truss-out Scaffolder (CIC) study guide has 9 sections and about 3,413 words.
01Statutory 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 Factories and Industrial Undertakings Ordinance (Cap.
412 words, about 2 min02Safety responsibilities and duty holders
Safety responsibilities and duty holders is the domain that tests who must do what when a truss-out scaffold is planned, erected, used and removed. The principal contractor controls the site and must provide a safe system of work, a suitable design, competent supervision, safe access, PPE, training, emergency arrangements and public protection.
377 words, about 2 min03Truss-out scaffold design principles
Truss-out scaffold design principles is the domain that tests whether you understand the load path from the platform, through the brackets and ties, into the building facade. Design considers dead load (tubes, couplers, boards, toe boards, mesh), live load (workers, tools, materials), and wind load, including uplift and lateral pressure.
385 words, about 2 min04Materials and components
Materials and components is the domain that tests whether you can select compatible scaffold parts and reject damaged items before they go into a truss-out scaffold. Steel scaffold tubes are commonly 48.3 mm outside diameter and must be straight, free of cracks, deep dents, severe corrosion and crushed ends.
394 words, about 2 min05Erection, alteration and dismantling procedures for truss-out scaffolds on building facades
Erection, alteration and dismantling procedures is the domain that tests sequence, stability and control when a truss-out scaffold is built on a live facade. Before work starts, confirm the design, bracket spacing, anchor type and setting, tie-back positions, platform levels, access and exclusion zones.
362 words, about 2 min06Fall prevention and personal protective equipment: safety belts and lanyards, independent lifelines, anchorage points, and working platforms
Fall prevention and personal protective equipment is the domain that tests the hierarchy of control and the correct use of belts, lanyards, lifelines and platforms on facade work. First avoid work at height; then prevent falls with a properly designed working platform, guardrails, toe boards and mesh; fall arrest is the last line.
389 words, about 2 min07Hazards of working at height in occupied buildings: public protection, falling objects, overhead cables, and interface with residents and other trades
Hazards of working at height in occupied buildings is the domain that tests how you protect the public, residents and other trades while working on a live facade. Before erecting, define the drop zone and protect it with robust hoarding, covered walkway, fan net or catch platform as designed.
371 words, about 2 min08Inspection, tagging and maintenance: pre-use checks, periodic inspection, scaffold tags and records, and reporting defects
Inspection, tagging and maintenance is the domain that tests how you prove a truss-out scaffold is safe at the point of use and after changing conditions. A competent person inspects before first use, after erection, after alteration, after damage or impact, after weather likely to affect stability (for example a typhoon or black rainstorm), and at the periodic interval required by the Construction Sites (Safety) Regulations, normally at least every 14 days.
368 words, about 2 min09Emergency response, incident reporting and accident prevention on facade works
Emergency response, incident reporting and accident prevention is the domain that tests what happens when something goes wrong on a facade scaffold and how to stop it recurring. Before work starts, prepare a rescue plan for a fallen or suspended worker, a collapsed bracket, a fire, and a dropped object.
