Workplace Safety and Health Act (WSHA): What Every Singapore SME Must Know

The Workplace Safety and Health Act (WSHA) is Singapore's primary legislation governing workplace safety. Unlike many business regulations that feel abstract until something goes wrong, the WSHA has teeth: penalties can reach S$500,000 in fines and 2 years' imprisonment — and the Ministry of Manpower (MOM) actively enforces them.

For SME owners, the WSHA can seem like it only applies to construction sites and factories. It does not. The Act covers every workplace in Singapore, including offices, retail shops, restaurants, warehouses, and even home-based businesses with employees.

This guide breaks down what you need to know and do, in practical terms.

Who Must Comply

The WSHA applies broadly. If you have a workplace in Singapore, you have obligations.

Employers

Every employer must, so far as is reasonably practicable, ensure the safety and health of:

• All employees at the workplace
• Independent contractors and their employees
• Visitors to the workplace

Occupiers of Workplaces

If you lease or own a workplace, you have duties as an occupier — even if the people working there are not your employees.

Self-Employed Persons

Self-employed individuals must take reasonably practicable measures to ensure their work does not affect the safety and health of others.

The Key Phrase: "Reasonably Practicable"

The WSHA uses the standard of "reasonably practicable" — similar to how the PDPA uses "reasonable" for data protection measures. This means the measures you must take are proportionate to:

• The likelihood and severity of the hazard
• The state of knowledge about the hazard
• The availability and suitability of risk controls
• The cost of implementing the controls relative to the risk

A 5-person office is not expected to have the same safety infrastructure as a petrochemical plant. But every business must demonstrate that it has identified hazards and taken reasonable steps to manage them.

Core Requirements

1. Risk Assessment

Every workplace must conduct a risk assessment to identify hazards and evaluate risks to safety and health. This is the foundation of WSHA compliance.

What a risk assessment covers:

• Identify hazards: What could cause harm? (physical, chemical, biological, ergonomic, psychosocial)
• Assess risks: How likely is the hazard to cause harm, and how severe could the harm be?
• Implement controls: What measures will you put in place to eliminate or reduce the risk?
• Document everything: Keep a written record of your assessment, findings, and controls
• Review regularly: Update the assessment when work processes change, after incidents, or at least annually

For offices, common hazards include:

• Slips, trips, and falls (wet floors, trailing cables, cluttered walkways)
• Ergonomic risks (poor workstation setup, prolonged sitting)
• Electrical hazards (overloaded power strips, damaged cables)
• Fire risks (blocked fire exits, missing extinguishers)
• Indoor air quality (inadequate ventilation, mould)

2. Safe Work Procedures

Based on your risk assessment, develop safe work procedures for activities that involve identified risks. These procedures should:

• Be documented in writing
• Be communicated to all relevant workers
• Be practically followed (not just filed away)
• Be reviewed and updated regularly

3. Safety and Health Training

Train your employees on:

• The specific hazards in your workplace
• Safe work procedures relevant to their roles
• Emergency procedures (fire evacuation, first aid contacts)
• How to report hazards and incidents
• Proper use of personal protective equipment (PPE) if applicable

For office workers, this typically includes:

• Ergonomic workstation setup
• Fire evacuation procedures
• First aid awareness
• Basic electrical safety

4. Incident Reporting

You must report certain workplace incidents to the Ministry of Manpower through the iReport system:

Must report within 10 days:

• Workplace fatalities
• Major injuries (fractures, amputations, loss of sight, etc.)
• Dangerous occurrences (structural collapse, electrical explosion, etc.)

Must report within 10 days:

• Workplace injuries resulting in more than 3 consecutive days of hospitalisation leave (including non-working days)

Record keeping:

• Maintain a record of all workplace injuries and incidents
• Keep records for at least 3 years
• Records must be available for inspection by MOM officers

5. Workplace Safety and Health Committee

Workplaces with 50 or more employees must establish a Workplace Safety and Health (WSH) Committee. This committee must:

• Include management and worker representatives
• Meet at least once every 3 months
• Review workplace safety performance
• Investigate incidents and near-misses
• Recommend safety improvements

For smaller businesses, a formal WSH Committee is not required, but you should still have someone responsible for safety matters.

Penalties for Non-Compliance

The WSHA imposes significant penalties, and MOM regularly takes enforcement action.

Financial Penalties

Imprisonment

For serious offences, imprisonment of up to 2 years can be imposed, particularly for repeat offenders or cases involving negligence leading to death or serious injury.

Stop Work Orders

MOM can issue a Stop Work Order that halts all work at your workplace until safety issues are resolved. For businesses, this means:

• Zero revenue during the stoppage
• Contractual penalties from delayed deliveries or projects
• Reputational damage

Composition Fines

For minor offences, MOM may offer a composition fine (typically S$1,000 to S$5,000) as an alternative to prosecution. Accepting a composition fine is an admission of the offence.

Practical Compliance Checklist for SMEs

Use this checklist to assess your current compliance:

Documentation

• Risk assessment conducted and documented
• Safe work procedures documented for identified risks
• Emergency response plan in place
• Safety training records maintained
• Incident records kept for at least 3 years

Physical Workplace

• Fire exits unobstructed and clearly marked
• Fire extinguishers present, accessible, and serviced
• First aid kit available and stocked
• Electrical panels and equipment properly maintained
• Adequate lighting in all work areas
• Walkways clear of trip hazards
• Ventilation adequate for the space

People

• All employees trained on workplace safety basics
• Fire evacuation procedure communicated to all staff
• First aider(s) designated (required for workplaces with 25+ employees)
• Person responsible for safety identified

Processes

• Process for reporting hazards and incidents established
• iReport account set up for MOM reporting
• Annual risk assessment review scheduled
• New employee safety orientation process in place

WSHA and Other Compliance Obligations

Workplace safety is one of several regulatory obligations Singapore SMEs must manage alongside PDPA compliance, employment law, and industry-specific regulations.

The common thread across all these frameworks is documentation and proactive management. Just as the PDPA requires you to appoint a DPO and maintain data protection policies, the WSHA requires you to conduct risk assessments and maintain safety documentation.

For SMEs, managing multiple compliance frameworks can feel overwhelming. Tools that centralise compliance tracking — monitoring PDPA, workplace safety, employment law, and other obligations in one place — can save significant time and reduce the risk of gaps.
