HK Confined Space Competent Person Test · Work through your exam, one topic at a time.
The Confined Space Competent Person Test (密閉空間合資格人員測試) is a Hong Kong assessment of whether a candidate can work safely in, or supervise work in, confined spaces under the Factories and Industrial Undertakings (Confined Spaces) Regulation and the broader occupational safety and health framework. It is aimed at workers, supervisors, safety officers and contractors who enter or control entry to tanks, pits, sewers, manholes, ducts and similar spaces. The HK Confined Space Competent Person Test study guide has 8 sections and about 3,678 words.

This domain tests your knowledge of the Factories and Industrial Undertakings (Confined Spaces) Regulation (Cap. 59AE) and how it sits alongside the F&IU Ordinance (Cap.
492 words, about 2 min02Definition and Identification of Confined Spaces; Classification and Risk Assessment
This domain tests the legal definition of a confined space, how to identify one on a real site, and how to classify and assess the risk before any entry. A confined space is any place such as a chamber, tank, vat, silo, pit, trench, pipe, sewer, flue, well or similar space which, by virtue of its enclosed nature, gives rise to a reasonably foreseeable specified risk .
490 words, about 2 min03Atmospheric Hazards: Oxygen, Flammable and Toxic Gases
This domain tests the atmospheres that kill in confined spaces: oxygen deficiency and enrichment, flammable gases and vapours, and toxic gases such as hydrogen sulphide and carbon monoxide. Normal air is 20.9% oxygen; the usual entry range is 19.5% to 23.5%.
436 words, about 2 min04Physical and Other Hazards: Engulfment, Falls, Electricity, Machinery, Heat, Noise, Drowning
This domain tests the non-atmospheric hazards that the risk assessment must capture, and the controls that follow from them. Free-flowing solids such as grain, sand, cement, sugar and fly ash, and liquids such as slurry and sewage.
461 words, about 2 min05Gas Detection and Monitoring: Instruments, Calibration, Sampling and Action Levels
This domain tests whether you can select, verify and use a gas detector correctly, and whether you understand where and when to sample. Sensors matched to the hazards identified: oxygen, LEL, hydrogen sulphide, carbon monoxide, plus specific toxics as required.
465 words, about 2 min06Control Measures and Safe Systems of Work: Isolation, Purging, Permit-to-Work, Entry Procedures
This domain tests the practical controls that make an entry safe: the hierarchy of control, isolation and lockout, purging and ventilation, the permit-to-work, and the entry procedure itself. Avoid entry - remote cameras, long tools, external cleaning; engineer out the hazard - isolation and ventilation; administrative controls - permit, training, standby person; PPE last.
