HK Confined Space Competent Person Test study plan

List the statutory duties the FIU (Confined Spaces) Regulation places on the proprietor, contractor, competent person and authorized person, and state which duty belongs to whom without notes.

Distinguish a 'confined space' from an 'enclosed space' using the Regulation's definition, and justify the classification of five given workplace descriptions.

Explain the legal meaning of 'competent person' and 'authorized person' under Hong Kong law, and describe how competence is normally evidenced (training, experience, certification).

Outline the risk assessment process required before entry, including hazard identification, evaluation of risk, and recording of findings.

Explain oxygen deficiency and oxygen enrichment, stating the hazards and typical causes of each, and identify the safe working range used in Hong Kong practice.

Describe the flammability of gases and vapours in terms of lower and upper explosive limits, and explain how the LEL reading relates to entry decisions.

Identify the sources, health effects and exposure symptoms of hydrogen sulphide and carbon monoxide, and state the action levels that trigger evacuation.

Compare the working principles of catalytic combustion, electrochemical and infrared sensors, and match each to the gas it best detects.

Plan a sampling strategy for a deep, poorly ventilated space, covering pre-entry testing, stratified sampling at multiple depths, and continuous monitoring during occupancy.

Categorise physical hazards (engulfment, falls, electricity, moving machinery, heat, noise, drowning) and match each to a control measure that follows the hierarchy of control.

Explain how engulfment occurs in silos, hoppers and sludge tanks, and describe the specific controls that prevent it.

Describe the physiological effects of heat stress in a confined space and the measures used to monitor and control it.

Identify the conditions under which a space becomes an oxygen-deficient or toxic atmosphere as a result of the work itself (welding, painting, cleaning, purging).

Write a calibration and bump-test schedule for a multi-gas detector, stating frequency, acceptance criteria and the action to take on a failed test.

Explain the purpose and elements of a permit-to-work system for confined space entry, including issue, display, suspension, cancellation and record retention.

Describe isolation and lockout procedures for energy sources (electrical, mechanical, process, fluid) and explain the role of a personal lock and tag.

Explain purging and ventilation as control measures, distinguishing dilution ventilation from forced-air supply, and state when each is appropriate.

Draft a step-by-step entry procedure from preparation through exit, including pre-entry briefing, gas testing, standby arrangements and communication checks.

Explain the elements of a rescue plan and why non-entry rescue is preferred over entry rescue.

Describe the selection, pre-use inspection and use of tripod, winch and retrieval systems, including fall protection and harness fit.

Compare the types of breathing apparatus used in confined space work (self-contained and supplied-air) and state the limitations of each.

Specify the communication methods used between entrant, standby person and entry supervisor, including agreed signals and emergency notification.

Define the duties of the competent person, authorized person, standby person and entry supervisor, and explain where their responsibilities overlap and where they must not.

Explain the standby person's duties during entry, including headcount control, continuous monitoring, and the rule on leaving the post.

Describe how a contractor and a host employer coordinate confined space work, including information exchange, joint risk assessment and permit responsibility.

Outline the first-aid priorities for a collapsed entrant, including the rule against unprotected rescue entry.

Trace the legal chain from risk assessment through permit issue to entry and rescue, identifying the statutory requirement behind each step.

Identify common non-compliances found in confined space enforcement (inadequate gas testing, missing standby person, no rescue plan) and state the required corrective action for each.

Explain the record-keeping obligations for gas tests, permits, training and equipment maintenance.

Prepare written answers to scenario questions that combine legal duties with practical control measures.

Recall without notes the key numerical values used in the exam: oxygen limits, flammable gas action levels, H2S and CO action levels, and calibration intervals.

Complete a timed full-length mock test and score it by domain to identify remaining weak areas.

Re-study the two weakest domains and write a one-page summary of each from memory.

Rehearse the sequence of actions for an alarm activation during entry, from entrant withdrawal to rescue activation.
