Investigation and Inquiry of Workplace Accidents: Legal Framework under the Workplace Safety and Health Act 2006
Workplace safety is a paramount concern in Singapore’s regulatory landscape, governed comprehensively by the Workplace Safety and Health Act 2006 (WSHA). Part 6 of the WSHA establishes a robust legal framework for the investigation and inquiry of workplace accidents, dangerous occurrences, and occupational diseases. This article provides an authoritative analysis of the key provisions within this Part, explaining their purposes, penalties for non-compliance, and relevant cross-references to other legislation.
Section 24: Commissioner’s Power to Direct Investigations
"Where the Commissioner becomes aware of any accident, dangerous occurrence or occupational disease in a workplace, the Commissioner may direct an inspector to investigate the circumstances of the accident, dangerous occurrence or occupational disease." — Section 24, Workplace Safety and Health Act 2006

Section 24 empowers the Commissioner for Workplace Safety and Health to initiate investigations upon becoming aware of any workplace accident, dangerous occurrence, or occupational disease. This provision exists to ensure that incidents are promptly and thoroughly examined to determine their causes and to prevent recurrence.
The rationale behind this provision is to enable a proactive regulatory response. By authorizing the Commissioner to direct inspectors to investigate, the law ensures that workplace hazards are identified and addressed swiftly, thereby protecting workers and the public from ongoing risks. This investigatory power is fundamental to the enforcement of workplace safety standards and the promotion of a culture of safety.
Section 25: Prohibition on Alteration of Machinery or Scene of Incident
"A person must not, without the consent of the Commissioner—alter, replace, remove or add to any machinery, equipment, plant or article which may have contributed to the cause of any accident resulting in the death of any person or any dangerous occurrence or occupational disease; or modify the scene of the fatal accident or dangerous occurrence or the scene where the occupational disease occurred." — Section 25(1), Workplace Safety and Health Act 2006

Section 25 prohibits any alteration, replacement, removal, or addition to machinery or the scene of an accident without the Commissioner’s consent. This provision is critical to preserving the integrity of the accident scene and any equipment involved, which is essential for accurate investigation.
The purpose of this restriction is to prevent tampering or destruction of evidence that could hinder the investigation into the causes of the accident or occupational disease. By mandating occupiers to prevent unauthorized alterations, the law safeguards the investigative process and helps ensure accountability.
"Any person who contravenes subsection (1) and any occupier of a workplace who contravenes subsection (2) shall be guilty of an offence and shall be liable on conviction to a fine not exceeding $10,000 or to imprisonment for a term not exceeding 12 months or to both." — Section 25(5), Workplace Safety and Health Act 2006

The penalties prescribed under Section 25(5) underscore the seriousness with which the law treats interference with accident scenes or machinery. The possibility of fines and imprisonment serves as a deterrent against non-compliance, reinforcing the importance of preserving evidence for effective enforcement and prevention.
Section 26: Minister’s Power to Appoint Inquiry Committees
"The Minister may appoint an Inquiry Committee to hold an inquiry into any accident, dangerous occurrence or occupational disease that has occurred in a workplace and into its causes and circumstances, and direct that the Committee reports its findings to the Minister." — Section 26(1), Workplace Safety and Health Act 2006
Verify Section 26 in source document →
Section 26 grants the Minister the authority to establish Inquiry Committees to conduct formal inquiries into workplace incidents. These committees investigate the causes and circumstances of accidents or occupational diseases and report their findings to the Minister.
This provision exists to facilitate a more detailed and formal examination of serious incidents, beyond routine investigations. Inquiry Committees can summon witnesses, require evidence, and provide comprehensive reports that inform policy decisions and regulatory improvements. The inquiry process enhances transparency and accountability in workplace safety governance.
"Any person who—(a) fails to comply with any summons, order or requisition of the District Judge; or (b) prevents or impedes the Inquiry Committee in the execution of its duties, shall be guilty of an offence and shall be liable on conviction to a fine not exceeding $2,000." — Section 26(7), Workplace Safety and Health Act 2006
The penalties under Section 26(7) ensure cooperation with Inquiry Committees. By criminalizing obstruction or non-compliance, the law guarantees that inquiries can proceed unhindered, thereby upholding the integrity and effectiveness of the investigative process.
Section 27: Mandatory Notification and Reporting Requirements
"The Minister may by regulations require an employer, a platform operator, an occupier, a registered medical practitioner or any other person to notify or to submit a report to the Commissioner in the event of an accident, a dangerous occurrence or an occupational disease in a prescribed workplace." — Section 27(1), Workplace Safety and Health Act 2006
Verify Section 27 in source document →
Section 27 empowers the Minister to impose regulatory obligations on various stakeholders to notify or report workplace incidents to the Commissioner. This ensures that the authorities are promptly informed of any occurrences that may impact workplace safety.
The purpose of this provision is to establish a systematic and timely flow of information, which is essential for effective monitoring, investigation, and intervention. By mandating notification, the law facilitates early detection of hazards and supports data collection for safety analysis and policy formulation.
Sections 27A and 27B: Learning Reports and Evidentiary Protection
"Where the Commissioner considers it necessary in the interest of the public, or a section of the public, the Commissioner may prepare and publish a learning report on any accident, dangerous occurrence or occupational disease in a workplace that is the subject of an investigation under section 24." — Section 27A(1), Workplace Safety and Health Act 2006
Verify Section 27A in source document →
Section 27A authorizes the Commissioner to prepare and publish learning reports based on investigations. These reports aim to disseminate lessons learned from incidents to prevent recurrence and enhance workplace safety awareness.
The rationale behind this provision is to promote a culture of continuous improvement and shared learning. By making findings publicly available, the Commissioner helps employers, workers, and the public understand risks and adopt preventive measures.
"Subject to subsection (3), a learning report, or any draft of the learning report, is not admissible in evidence in any civil, criminal, arbitral or disciplinary proceedings before any court, tribunal or body, or any proceedings under the Work Injury Compensation Act 2019 or the Work Injury Compensation Act (Cap. 354, 2009 Revised Edition) repealed by that Act." — Section 27B(1), Workplace Safety and Health Act 2006
Verify Section 27B in source document →
Section 27B provides that learning reports are generally inadmissible as evidence in legal or disciplinary proceedings. This evidentiary protection encourages candid and comprehensive reporting without fear of legal repercussions.
This provision exists to balance transparency with fairness, ensuring that the primary purpose of learning reports is safety improvement rather than litigation. It fosters an environment where stakeholders can openly share information to enhance workplace safety.
"Subsections (1) and (2) do not apply to the following: (a) an inquiry under section 26; (b) an inquiry under the Coroners Act 2010; (c) an inquiry by a commission of inquiry or a committee of inquiry under the Inquiries Act 2007." — Section 27B(3), Workplace Safety and Health Act 2006
Verify Section 27B in source document →
However, Section 27B(3) clarifies exceptions where learning reports may be admissible, such as formal inquiries under Section 26, the Coroners Act 2010, or the Inquiries Act 2007. This ensures that in certain judicial or quasi-judicial contexts, relevant information can be considered to establish facts and accountability.
Cross-References to Other Legislation
Part 6 of the WSHA also cross-references other key statutes to ensure a cohesive legal framework for workplace safety and injury compensation:
- Work Injury Compensation Act 2019: Section 27B(1) references this Act, highlighting that learning reports are generally inadmissible in proceedings under this Act, preserving the focus on compensation without prejudicing safety investigations.
- Coroners Act 2010: Section 27B(3)(b) exempts inquiries under this Act from the evidentiary protection, allowing coronial investigations into workplace deaths to access learning reports.
- Inquiries Act 2007: Section 27B(3)(c) includes inquiries by commissions or committees under this Act as exceptions, facilitating comprehensive fact-finding in serious incidents.
These cross-references ensure that workplace safety investigations are integrated with broader legal processes concerning injury, death, and public inquiries, promoting consistency and thoroughness in addressing workplace incidents.
Conclusion
Part 6 of the Workplace Safety and Health Act 2006 establishes a comprehensive legal framework for the investigation, inquiry, and reporting of workplace accidents, dangerous occurrences, and occupational diseases. The provisions empower the Commissioner and the Minister to conduct investigations and inquiries, mandate notification and reporting, protect the integrity of accident scenes, and promote learning through published reports.
The penalties for non-compliance underscore the importance of cooperation and adherence to these provisions, ensuring that investigations are effective and that workplace safety is continuously improved. Cross-references to related legislation further enhance the coherence of Singapore’s workplace safety regime.
By understanding these key provisions and their purposes, employers, occupiers, medical practitioners, and other stakeholders can better comply with their legal obligations and contribute to a safer working environment.
