1Under the Factories and Industrial Undertakings (Confined Spaces) Regulation, a confined space is any place that, by virtue of its enclosed nature, gives rise to what?

A.A reasonably foreseeable specified risk

B.Any work that requires a Green Card

C.Only spaces with permanently locked doors

D.Any outdoor excavation deeper than 1.2 m

Explanation: Cap. 59AE defines a confined space as any place in which, by virtue of its enclosed nature, there arises a reasonably foreseeable specified risk, and lists examples such as chambers, tanks, sewers, tunnels and silos where such risk arises. Enclosure alone is not enough without a foreseeable specified risk.

2Which of the following is a "specified risk" under the Confined Spaces Regulation?

A.Loss of consciousness or asphyxiation from gas, fume, vapour or lack of oxygen

B.Any trip hazard on an open construction walkway

C.Noise exposure above 85 dB(A) on an open site

D.Sunburn while working outdoors

Explanation: Specified risks include fire/explosion injury, heat-related loss of consciousness, asphyxiation from gas/fume/vapour or lack of oxygen, drowning from rising liquid, and asphyxiation/entrapment from free-flowing solids. Ordinary outdoor site hazards without the enclosed-space context are not confined-space specified risks.

3What is the legal status of the Labour Department's Code of Practice for Safety and Health at Work in Confined Spaces?

A.Failure to observe it is not itself an offence, but a court may treat that failure as relevant when deciding whether safety legislation was breached

B.It has no legal relevance in any criminal proceedings

C.Every CoP recommendation is automatically a criminal offence if missed

D.It replaces Cap. 59AE entirely

Explanation: The CoP is issued under section 7A of the Factories and Industrial Undertakings Ordinance. Non-observance is not itself an offence, but courts may take failure to follow it into account when judging breaches of the Ordinance and Confined Spaces Regulation. It guides practice; it does not repeal the Regulation.

4To which work does the Confined Spaces Regulation apply?

A.Work inside a confined space in an industrial undertaking, and associated work in the immediate vicinity

B.Only underground mining work outside Hong Kong

C.Only office cleaning in multi-storey commercial buildings

D.Only maritime work on vessels registered overseas

Explanation: Section 3 applies the Regulation to work within a confined space in an industrial undertaking and to associated work in the immediate vicinity of that confined space work. The CoP stresses this wider supervisory and support perimeter.

5Which place is expressly listed in Cap. 59AE as an example that may be a confined space when a specified risk arises?

A.Sewer, tunnel, pipe, flue, boiler, shaft or silo

B.Open football pitch with no enclosure

C.Public pavement beside a busy road

D.Rooftop terrace with free open air on all sides

Explanation: Section 2 lists chambers, tanks, vats, pits, wells, sewers, tunnels, pipes, flues, boilers, pressure receivers, hatches, caissons, shafts and silos among places that can be confined spaces when a specified risk arises. Open, freely ventilated outdoor areas without enclosure generally fall outside that list.

6Who authorises training course providers to issue confined space competent person certificates in Hong Kong?

A.The Commissioner for Labour

B.Any private tutor without approval

C.Only the Transport Department

D.Only the Food and Environmental Hygiene Department

Explanation: Under the Confined Spaces Regulation and CoP, the Commissioner for Labour approves suitable training course providers and authorises them to issue certificates for certified workers and competent persons. Unapproved tutors cannot issue legally recognised certificates.

7When can waterproofing with volatile chemicals inside a water tank create a confined space risk even if the structure previously seemed less hazardous?

A.When the work or materials create a specified risk due to accumulation of chemicals in the enclosed space

B.Only if the tank is outdoors and fully open to weather

C.Never, because waterproofing chemicals cannot create atmospheric hazards

D.Only after the tank has been demolished

Explanation: The CoP explains that enclosed places can become confined spaces because of the work or materials used—for example volatile waterproofing chemicals accumulating in a water tank and causing loss of consciousness. Risk depends on enclosure plus foreseeable specified risk from the activity.

8Which ordinance primarily underpins the Commissioner's power to issue the confined spaces Code of Practice?

A.Factories and Industrial Undertakings Ordinance (Cap. 59)

B.Road Traffic Ordinance (Cap. 374)

C.Building Management Ordinance (Cap. 344)

D.Immigration Ordinance (Cap. 115)

Explanation: The CoP is issued by the Commissioner for Labour under section 7A of the Factories and Industrial Undertakings Ordinance (Cap. 59) to give practical guidance on sections 6A and 6B and on the Confined Spaces Regulation. Other ordinances do not authorise this CoP.

9Besides Cap. 59AE, which other Hong Kong OSH law does the CoP remind duty holders may also apply to confined space work?

A.Occupational Safety and Health Ordinance (Cap. 509) and other FIU subsidiary regulations as applicable

B.Only the Banking Ordinance

C.Only the Copyright Ordinance

D.Only the Marriage Ordinance

Explanation: The CoP states that Cap. 509 and Cap. 59, with subsidiary regulations (for example construction sites safety, electricity, noise, lifting appliances and eye protection), may also apply depending on the work. Confined space compliance does not displace other OSH duties.

10According to the CoP, the statutory provisions cited in the May 2024 edition are those in force on which date?

A.30 November 2024

B.1 January 1997

C.1 July 1980

D.31 December 2030

Explanation: The CoP states that the statutory provisions cited are those in force on 30 November 2024, matching the effective date of the revised CoP. Candidates should study the May 2024 edition as the current practical guidance baseline.

About the HK Confined Space Competent Person Test Exam

The Hong Kong Safety Training Course for Competent Persons of Confined Spaces Operation is a Labour Department-recognised mandatory course for people who prepare confined space risk assessment reports and support safe entry under the Factories and Industrial Undertakings (Confined Spaces) Regulation (Cap. 59AE). Training emphasises risk assessment, atmospheric testing and interpretation, authorisation of entry through permit-to-work systems, emergency procedures, and the distinct duties of competent persons versus certified workers, aligned with the Labour Department’s Code of Practice for Safety and Health at Work in Confined Spaces (May 2024 edition, in force from 30 November 2024).

Assessment

Labour Department-recognised mandatory safety training for persons who will act as confined space competent persons. Courses combine classroom theory covering legislation, hazards, risk assessment, gas monitoring, permit-to-work, work procedures, emergencies and PPE with a provider-set written assessment; many providers (including OSHC CN) also require a practical examination. Award typically requires 100% attendance and a pass in the provider’s assessments.

Time Limit

Course duration varies by recognised provider (examples include ~7-hour short courses and OSHC’s 20 hours plus practical exam). Written examination duration is set by the training centre for each class.

Passing Score

No single Labour Department-published territory-wide percentage pass mark. Providers require attendance and a pass in their written (and often practical) examination; confirm the exact pass criteria with your centre.

Exam Fee

Provider-set. OSHC CN schedule examples list about HK$1,620 (with GCG/SME concessions). Other recognised providers commonly charge roughly HK$420–HK$1,380 for competent-person or CP top-up modules. Confirm current fees before enrolment. (Labour Department-recognised training course providers authorised by the Commissioner for Labour)

HK Confined Space Competent Person Test Study Tips from Top Performers

1Memorise Hong Kong CoP atmospheric figures specifically: oxygen 19.5%–22% by volume, LEL Level 1 alarm at 5% LEL and Level 2 evacuation alarm at 10% LEL—do not rely on overseas OSHA defaults.

2Drill the role split: competent person assesses and recommends; proprietor/contractor verifies precautions and issues the permit-to-work; only certified workers enter; a standby person remains outside and maintains communication.

3Practise reading a risk assessment and permit together: if conditions or work methods change significantly, a fresh competent person assessment is required before work continues.

Frequently Asked Questions

Who recognises the Hong Kong confined space Competent Person course?

The Commissioner for Labour authorises suitable training course providers under the Factories and Industrial Undertakings (Confined Spaces) Regulation. An up-to-date list of recognised Safety Training Courses for Competent Persons of Confined Spaces Operation is published by the Labour Department. Only certificates from recognised providers meet the training limb of the statutory competent person definition.

What is the difference between a competent person and a certified worker?

A certified worker is trained and certificated to enter and work in a confined space. A competent person is trained/certificated (or is a registered safety officer) and, after at least one year’s relevant experience, prepares the written risk assessment and recommendations that underpin safe entry. Proprietors/contractors issue the permit-to-work; only certified workers may enter to work.

What oxygen range does the Hong Kong Code of Practice give for confined spaces?

The Labour Department Code of Practice states that oxygen in a confined space should not be less than 19.5% by volume nor greater than 22% by volume at normal atmospheric pressure, with alarm thresholds at those same levels. This upper limit differs from some overseas standards that use 23.5%.

How many questions and what pass mark does the official CP exam use?

Labour Department does not publish a single standardised MCQ count or territory-wide percentage pass mark for all recognised providers. Centres typically require full attendance and a pass in their own written (and often practical) assessments. This free bank has 100 practice questions to build underpinning knowledge.
