Workplace Accident at Your Company: MOM Investigation, Stop-Work Orders and Workplace Safety and Health Act Penalties

Short answer: After a workplace accident, the employer must notify MOM at once if a worker dies and file an incident report within 10 days. MOM may investigate, issue a remedial or stop-work order and compound or prosecute offences. A company faces fines of up to S$500,000, and its officers can be personally liable under section 48.

When a worker is hurt at your premises, the next few days decide how much exposure the company and its directors carry. This guide explains how workplace safety and health act penalties work in practice under the Workplace Safety and Health Act 2006 (the WSH Act) and the Workplace Safety and Health (Incident Reporting) Regulations, from the incident report through a Ministry of Manpower (MOM) investigation, stop-work orders, appeals and prosecution, to the separate work injury compensation claim. It states the law in force on 29 October 2026.

Raffles Corporate Services works with a panel of experienced Singapore law firms who offer cost-effective and efficient legal service and advice. This article is general information only and is not legal advice.

What should a company do in the first 10 days after a workplace accident?

Make the site safe, get the worker treated, notify MOM immediately if anyone has died, and file an incident report through MOM’s online iReport service within 10 days. The employer reports for its own employees; the occupier reports deaths of members of the public or self-employed persons and dangerous occurrences.

The legal basis is section 27 of the WSH Act and the Incident Reporting Regulations made under it. A dangerous occurrence is an event listed in the First Schedule to the Act, such as a crane toppling, and must be reported even if no one is hurt.

An employer “has notice” when the employee tells the employer, a supervisor or a designated person the date, place and cause of the injury, or when the employer learns of it any other way (regulation 6(4)). MOM says a late report must still be filed, with reasons. Records must be kept for 3 years (regulation 8).

A practical first-10-days sequence:

1. Make the area safe and arrange medical treatment.
2. For a fatal accident or dangerous occurrence, do not alter the scene or move equipment without MOM’s consent (section 25), and notify the Commissioner.
3. Collect witness names, photographs, permits, risk assessments and medical certificates.
4. Notify your work injury compensation insurer.
5. Submit the iReport within the 10-day window, and update it if the doctor issues more medical leave or light duty.
6. Brief the board and decide who deals with MOM, the insurer and, if needed, a lawyer.

MOM’s published guidance is on its what and when to report page.

What does a MOM investigation involve?

Once the Commissioner for Workplace Safety and Health learns of an accident, dangerous occurrence or occupational disease, he or she may direct an inspector to investigate (section 24). Inspectors have powers under Part 9 of the WSH Act to inspect, take samples, examine persons and require their attendance.

MOM says it may investigate at the accident site and, where an employee is injured, forwards the report to the employer’s insurer. Expect requests for risk assessments, safe work procedures, training records, permits-to-work and contractor agreements, and statements from supervisors and managers.

Three further points:

• Altering machinery or the scene of a fatal accident or dangerous occurrence without the Commissioner’s consent is an offence carrying up to S$10,000 and/or 12 months’ jail, and the occupier is presumed responsible unless it proves otherwise (section 25).
• The Minister may appoint an Inquiry Committee chaired by a District Judge, sitting in open court; if the judge thinks criminal proceedings should follow, the report goes to the Public Prosecutor (section 26).
• MOM may publish a learning report (section 27A), which is not admissible in civil, criminal or work injury compensation proceedings (section 27B).

Remedial orders and stop-work orders: what are they, and can you appeal?

A remedial order directs a person to fix a danger or comply with a duty within a stated period. A stop-work order requires work to cease immediately, either indefinitely or until the Commissioner is satisfied the danger is remedied (section 21). Either order may be served on whoever controls the workplace or the work, owes the relevant duty, or poses the risk.

Failing to comply with a remedial order carries up to S$50,000 and/or 12 months’ jail, plus S$5,000 a day (section 21(6)). Breaching a stop-work order carries up to S$500,000 and/or 12 months’ jail, plus S$20,000 a day (section 21(7)), and the suspect may be arrested without warrant (section 49). The Commissioner may also carry out the work and recover the cost as a debt (section 21(8) and (9)).

Appeals go to the Minister for Manpower within 14 days of service, and the Minister may rescind or vary the order (section 22). The effect differs:

• A remedial order does not take effect while the appeal is pending.
• A stop-work order must be complied with while the appeal is pending, and stays in force until it is rescinded or varied.

During MOM’s enhanced enforcement period from 26 June to 31 July 2026, the minimum duration of a stop-work order rose from five to eight weeks. MOM said the measures would be extended if safety outcomes did not improve, so check MOM’s current position.

What are the Workplace Safety and Health Act penalties?

Penalties depend on the provision breached. Breaching a general duty under Part 4, such as the employer’s duty in section 12 to take reasonably practicable measures for employees’ safety, is an offence under section 20, punishable under the general penalties in section 50.

The section 51 enhanced penalty is narrow: it applies only where a person with an earlier conviction for an offence that caused a death is convicted again of the same offence causing another death.

Subsidiary legislation has its own penalties. From 1 June 2024, MOM raised the maximum first-conviction fine for the most serious breaches, those that are a major cause of death, serious injury or a dangerous occurrence, from S$20,000 to S$50,000.

Under section 47, where a duty is to act “so far as is reasonably practicable”, the accused must prove it was not reasonably practicable to do more. Under section 52, the court may also order the cause of the contravention to be remedied.

See MOM’s liabilities and penalties page and the Act on Singapore Statutes Online. The version current on 29 October 2026 shows no amendments by a 2025 or 2026 amending Act; the main recent change, from 1 January 2025, extended duties to platform operators and platform workers.

Composition or prosecution?

For offences prescribed as compoundable, the Commissioner may compound by collecting up to half the maximum fine or S$5,000, whichever is lower, after which no further proceedings are taken (section 56). During the June to July 2026 enhanced enforcement period, MOM raised the composition amount for first-time offences found during inspections from S$2,000 to S$3,000.

Offences that are not compounded may be prosecuted. A District Court can try any offence under the Act and impose the full penalty (section 54), with proceedings under the Criminal Procedure Code 2010. The company is represented in court by a Singapore Advocate and Solicitor.

Can directors and managers be prosecuted personally?

Yes. Under section 48, when a company commits an offence under the WSH Act, each officer is also guilty unless he or she proves the offence happened without his or her consent or connivance and that he or she exercised all due diligence for that role.

“Officer” includes any director, chief executive, manager or secretary, and anyone purporting to act as one. The burden is on the officer, so board minutes and safety reports to the board matter. See our article on director due diligence under the WSH Act; a similar pattern applies to unpaid CPF contributions.

Directors should also check whether the company’s D&O liability insurance covers defence costs in regulatory investigations.

What is the Business Under Surveillance programme?

The Business Under Surveillance (BUS) programme is MOM’s scheme for companies with poor safety records: the company commits to an action plan, reports progress to MOM’s Occupational Safety and Health Division (OSHD) and faces frequent inspections until it shows significant improvement.

MOM assesses companies with fatal accidents, multiple injuries or dangerous occurrences, poor enforcement records, stop-work orders or, in construction, accumulated demerit points. A company that shows systemic lapses formally enters BUS, and MOM publishes the list of companies in the programme.

How does a WSH investigation interact with a WICA claim?

They run in parallel but are separate. The WSH investigation concerns criminal liability; a Work Injury Compensation Act 2019 (WICA) claim is no-fault compensation for the employee, usually handled by the employer’s designated insurer.

One iReport covers both regimes. MOM forwards it to your insurer and asks the employee whether he or she wishes to claim under WICA. Meanwhile the employer must keep paying medical leave wages and medical expenses, then seek reimbursement. The employee may claim under WICA or common law, but not both, and has 1 year from the accident to decide.

Our WICA guide for employers covers insurance, compensation limits and disputes.

Who does what: company secretary, insurer and Advocate and Solicitor?

The company secretary keeps the corporate record straight, the insurer handles compensation, and any criminal defence or civil claim is handled by a Singapore Advocate and Solicitor. Raffles Corporate Services does not give legal advice or act in court.

Timeline and cost drivers (assumes one injured employee, no fatality):

Lawyers’ fees depend on the charge, the evidence and whether the company pleads guilty, so we do not quote them. If charges are likely, speak to a lawyer early.

What mistakes do companies make after a workplace accident?

• Treating a “minor” injury as not reportable. Any medical leave, hospitalisation or light duty triggers the 10-day report.
• Cleaning up the scene or repairing equipment after a fatality or dangerous occurrence without MOM’s consent.
• Restarting work under a stop-work order because an appeal has been filed. The order stays in force pending the appeal.
• Pressuring doctors to shorten medical leave. MOM warns that errant employers may be referred to other authorities, including the CPIB.
• Leaving no paper trail of board-level safety oversight, which weakens the section 48 defence for directors.

If foreign employees are involved, work pass matters are handled by our associated MOM-licensed agency, Little Big Employment Agency; our sister site covers employment and immigration services. Our free tools help with related payroll checks.

MOM may compound workplace safety offences instead of prosecuting. See composition offers from Singapore regulators for how to respond.

Frequently asked questions

Do I need to report an accident if the worker only got one day of medical leave?

Yes. Under regulation 6(1), an employer must report any accident in which the employee is certified unfit for work, hospitalised or placed on light duty, within 10 days after first having notice of it.

Does filing an iReport mean the company admits liability?

No. The report is a statutory duty. Whether an offence was committed is decided through MOM’s investigation and, if charged, the court. Compensation is assessed separately under WICA.

Can a director go to jail for a workplace death?

An individual convicted under the general penalty in section 50 faces up to S$200,000 and/or up to 2 years’ jail. Through section 48, directors and managers are guilty of the company’s offence unless they prove lack of consent or connivance and proper diligence.

Who conducts the defence if the company is charged?

Court proceedings are conducted by a Singapore Advocate and Solicitor. Your company secretary can prepare the corporate records, resolutions and filings that support the defence.
