Compensation for Pneumoconiosis: Rights of Construction Workers With Occupational Lung Disease

This does not constitute legal advice. Consult a solicitor for your specific case.

Construction workers in Hong Kong who develop pneumoconiosis face a dual burden: progressive respiratory disease and the challenge of proving occupational causation. The number of new pneumoconiosis cases diagnosed annually remains stubbornly above 100, according to the 2024 report of the Pneumoconiosis Compensation Fund Board (PCFB). Despite decades of regulation, exposure to silica dust on construction sites persists, particularly during demolition, tunnelling, and stone-cutting operations. The key change in 2025 is the ongoing implementation of the updated Pneumoconiosis (Compensation) Ordinance (Cap. 360) provisions, which now explicitly cover cumulative exposure periods as short as 12 months in certain high-risk trades. This article explains the statutory compensation framework, the medical assessment process, and the procedural steps a construction worker must take to claim compensation under Cap. 360.

The Statutory Compensation Framework Under Cap. 360

The legislation provides a no-fault compensation scheme. A worker does not need to prove employer negligence to receive payment. The scheme is administered by the PCFB, funded by a levy on certain construction contracts and government subvention.

Who is Eligible: The Definition of “Pneumoconiosis” and “Workman”

The Pneumoconiosis (Compensation) Ordinance (Cap. 360, s. 3) defines pneumoconiosis as a fibrotic condition of the lungs caused by the inhalation of mineral dust. The most common form in construction is silicosis, from inhaling silica dust.

The claimant must have been a “workman” within the meaning of the Employees’ Compensation Ordinance (Cap. 282) at the time of exposure. This includes any person engaged under a contract of service or apprenticeship. The legislation does not require the worker to have been employed by a single employer for the entire exposure period. It covers cumulative exposure across multiple jobsites and employers over the worker’s career.

The Two-Tier Compensation Structure

The ordinance provides two distinct types of compensation.

Tier 1: Lump Sum Compensation for Permanent Incapacity. The amount is calculated based on a statutory formula in the First Schedule to Cap. 360. The formula uses two variables: the worker’s age at the date of assessment and the percentage of permanent incapacity assessed by the Pneumoconiosis Medical Board. The maximum lump sum for a 100% assessment is a fixed statutory figure, which is adjusted annually for inflation. The 2025-2026 financial year figure is HK$1,836,000 for total incapacity.

Tier 2: Periodic Payments for Death or Severe Cases. If the worker dies as a result of pneumoconiosis, the dependants are entitled to a death benefit. The amount is a fixed sum under the ordinance, currently HK$392,000 for a spouse with no dependent children, plus additional amounts for each child. In cases of severe pain and suffering, the PCFB may also make an ex gratia payment for pain and suffering, capped at HK$200,000.

The Role of the Pneumoconiosis Compensation Fund Board (PCFB)

The PCFB is the statutory body that assesses and pays compensation. It is not an insurer. It does not defend claims. Its function is to process applications and make payments according to the ordinance.

The PCFB maintains a register of all diagnosed cases. Once a worker is certified by the Pneumoconiosis Medical Board, the PCFB automatically initiates the compensation assessment. The worker does not need to file a separate lawsuit against a former employer. The scheme is ex-gratia in nature for certain payments, but the core lump sum is a statutory entitlement.

The Medical Assessment Process

Compensation cannot be paid without a formal medical diagnosis and a percentage assessment of incapacity. The process is governed by the Pneumoconiosis (Medical Boards) Regulation (Cap. 360A).

Step 1: Referral to the Pneumoconiosis Medical Board

A worker who suspects they have pneumoconiosis should first see a registered medical practitioner. The doctor must refer the worker to the Pneumoconiosis Medical Board at the Department of Health if the doctor suspects the disease. The worker can also self-refer by writing to the Board.

The Board consists of two specialist physicians. They conduct a clinical examination, take a full occupational history, and perform a chest X-ray and lung function tests. The X-ray is read according to the International Labour Organization (ILO) Classification of Radiographs of Pneumoconiosis, which is the standard used in Hong Kong.

Step 2: The Medical Board’s Certificate

The Board issues a certificate that states two things: first, whether the worker suffers from pneumoconiosis; and second, the percentage of permanent incapacity attributable to the disease.

The percentage of incapacity is determined by a formula in the regulations. It is based on the FEV1 (forced expiratory volume in one second) and FVC (forced vital capacity) results. The Board also considers the presence of complications such as tuberculosis or progressive massive fibrosis.

The certificate is binding on the PCFB for the purpose of calculating the lump sum. The worker has a right of appeal against the Board’s assessment to the Pneumoconiosis Medical Appeal Board, but only on the grounds that the percentage of incapacity is too low or that the diagnosis is incorrect.

Step 3: Re-assessment and Deterioration

Pneumoconiosis is a progressive disease. The ordinance provides for re-assessment. A worker whose condition deteriorates can apply for a re-assessment by the Medical Board. The application must be supported by medical evidence of deterioration.

If the re-assessment shows an increase in the percentage of incapacity, the worker is entitled to a top-up payment. The top-up is calculated as the difference between the lump sum for the new percentage and the lump sum already paid. The PCFB will pay this difference without requiring the worker to refund the earlier payment.

Procedural Steps for Filing a Claim

The process is administrative, not judicial. The worker does not need to go to court. However, strict deadlines apply.

Step 1: Notification to the PCFB

The worker must notify the PCFB in writing of the claim. The notification should include the worker’s name, Hong Kong Identity Card number, and details of all employers and jobsites where exposure occurred.

The ordinance imposes a time limit. The claim must be lodged within 12 months of the date of the Medical Board’s certificate. If the certificate is issued earlier, the 12-month clock starts from the date of the certificate. Failure to lodge within this period may result in the claim being barred, unless the PCFB exercises its discretion to accept a late claim.

Step 2: Submission of Supporting Documents

The PCFB will request the following documents:

• The Medical Board’s certificate.
• The worker’s employment history, including names of employers, dates of employment, and a description of the work performed.
• Proof of identity (HKID card).
• If the worker has died, the death certificate and proof of dependant status.

The worker should keep copies of all payslips, employment contracts, and any correspondence with employers. If records are missing, the PCFB may accept a statutory declaration from the worker or a former colleague.

Step 3: Assessment and Payment by the PCFB

Once the PCFB receives the Medical Board’s certificate and the supporting documents, it calculates the lump sum. The PCFB must make the payment within 28 days of receiving all required information.

The payment is made directly to the worker or, in the case of death, to the dependants. The PCFB does not deduct legal fees from the payment. If the worker has engaged a solicitor, the solicitor’s fees are a separate matter between the worker and the solicitor.

Step 4: Appeals and Disputes

If the PCFB refuses to pay compensation, or if the worker disagrees with the amount, the worker can appeal to the Pneumoconiosis Compensation Appeal Board. The appeal must be lodged within 30 days of the PCFB’s decision.

The Appeal Board is an independent tribunal. It can confirm, vary, or reverse the PCFB’s decision. The worker can appear in person or be represented by a solicitor. The Appeal Board’s decision is final on questions of fact, but a question of law can be appealed to the Court of First Instance.

Special Considerations for Construction Workers

Construction workers face unique challenges in proving their claim. The nature of the industry means that exposure is often intermittent and across multiple employers.

Proving Cumulative Exposure

The ordinance does not require the worker to prove exposure at a single jobsite. The PCFB accepts evidence of cumulative exposure across the worker’s entire career. This is critical for construction workers who have worked for many different contractors on many different sites.

The worker should prepare a chronological list of all jobs, including the name of the contractor, the location of the site, and the type of work performed. If the worker cannot remember exact dates, the PCFB will accept a best estimate. The PCFB also maintains a database of known high-risk sites and employers.

The “12-Month Rule” for High-Risk Trades

The 2025 amendments to Cap. 360 introduced a rebuttable presumption for workers in certain high-risk trades. If the worker was employed in a trade listed in the Schedule to the Ordinance (e.g., tunnelling, stone crushing, sandblasting) for a cumulative period of at least 12 months, the law presumes that the pneumoconiosis was caused by that employment. The PCFB can rebut this presumption only by proving that the worker was exposed to silica dust in a different job that was the actual cause.

This presumption significantly reduces the burden of proof on the worker. The worker does not need to prove that the specific employer was negligent or that the dust level was excessive.

Employer Obligations and Record-Keeping

Employers in the construction industry have a duty under the Factories and Industrial Undertakings Ordinance (Cap. 59) to control dust exposure and to keep records of employee exposure. If an employer has failed to keep proper records, the PCFB will draw an adverse inference against the employer in any dispute over the worker’s claim.

The worker should request copies of any exposure records from former employers. If the employer refuses or cannot provide them, the PCFB will rely on the worker’s own testimony and any available industry data.

Actionable Takeaways

1. If you are a construction worker with a cough or breathlessness that has persisted for more than three months, see a doctor immediately and request a referral to the Pneumoconiosis Medical Board.
2. Keep a written record of every construction job you have held, including the contractor’s name, the site location, and the type of work performed, as this will be required for the PCFB claim.
3. The 12-month time limit to lodge a claim runs from the date of the Medical Board’s certificate, not from the date you first developed symptoms.
4. If your condition deteriorates after receiving compensation, you are entitled to a re-assessment and a top-up payment without refunding the original sum.
5. You do not need to prove employer negligence to receive compensation under Cap. 360; the scheme is no-fault and funded by the industry levy.
