Workplace Risk Assessment Guide for Singapore Employers

Every employer in Singapore has a legal obligation to ensure the safety and health of their workers. One of the most fundamental requirements under the Workplace Safety and Health Act is conducting a proper workplace risk assessment. Yet many employers find this process confusing or intimidating.

This comprehensive guide breaks down the risk assessment process into clear, actionable steps — helping you meet your legal obligations while creating a genuinely safer workplace.

Legal Requirements for Workplace Risk Assessment in Singapore

Under the Workplace Safety and Health (Risk Management) Regulations, employers in Singapore are required to:

• Conduct a risk assessment for all work activities that may pose a risk to employees or others
• Implement reasonably practicable measures to eliminate or reduce identified risks
• Review risk assessments at least once every three years, or whenever there is a significant change in work processes
• Keep records of all risk assessments for at least three years
• Communicate identified risks and control measures to all affected workers

Failure to conduct proper risk assessments can result in fines of up to SGD 200,000 and imprisonment of up to 12 months under the Workplace Safety and Health Act. Beyond legal compliance, effective risk management protects your most valuable asset — your people.

The 5-Step Risk Assessment Process

Step 1: Identify the Hazards

Walk through your workplace and identify anything that could potentially cause harm. Common methods include:

• Physical inspection: Walk the floor and observe all work activities
• Worker consultation: Ask employees about hazards they encounter daily
• Incident review: Analyse past accidents, near-misses, and incident reports
• Documentation review: Check safety data sheets, equipment manuals, and industry guidelines

Step 2: Determine Who Might Be Harmed and How

For each hazard identified, consider:

• Which workers are exposed to the hazard
• Whether visitors, contractors, or members of the public could be affected
• Whether certain groups are at higher risk (new workers, pregnant employees, young workers)
• The type and severity of injury or illness that could result

Step 3: Evaluate the Risks and Decide on Control Measures

Assess the likelihood and severity of each risk, then determine appropriate control measures using the hierarchy of controls:

• Elimination: Remove the hazard entirely (most effective)
• Substitution: Replace the hazardous material or process with a safer alternative
• Engineering controls: Install guards, ventilation systems, or barriers
• Administrative controls: Change work procedures, provide training, rotate workers
• Personal Protective Equipment (PPE): Provide appropriate safety gear (last resort)

Step 4: Record Your Findings and Implement Controls

Document your risk assessment using a standard format that includes:

• Description of each hazard
• Who is at risk
• Current risk rating (likelihood x severity)
• Control measures to be implemented
• Person responsible for implementation
• Target completion date
• Residual risk rating after controls are in place

Step 5: Review and Update Regularly

Risk assessments are living documents. Review and update them:

• At least every three years (as required by law)
• After any workplace accident or incident
• When new equipment, processes, or materials are introduced
• When there are changes in staffing or work organisation
• After receiving new safety information from suppliers or regulators

Common Workplace Hazards in Singapore

While every workplace is different, here are the most common hazard categories across Singapore industries:

Physical Hazards

• Slips, trips, and falls (the leading cause of workplace injuries in Singapore)
• Working at height
• Moving machinery and vehicles
• Noise exposure
• Electrical hazards

Chemical Hazards

• Exposure to hazardous substances
• Chemical spills and leaks
• Dust and fume inhalation
• Improper storage of flammable materials

Ergonomic Hazards

• Repetitive strain injuries
• Manual handling and lifting
• Poor workstation setup
• Prolonged standing or sitting

Psychosocial Hazards

• Work-related stress
• Workplace bullying and harassment
• Excessive workload
• Fatigue from long working hours

Risk Assessment Documentation Best Practices

Good documentation is essential for both legal compliance and effective safety management:

• Use a consistent format across all departments
• Include the date, assessor’s name, and department or work activity assessed
• Use a clear risk rating matrix (e.g., 5×5 likelihood vs severity)
• Be specific about hazards — “wet floor near loading bay” is better than “slipping hazard”
• Include photographic evidence where applicable
• Track implementation status of control measures
• Store records securely and make them accessible to relevant personnel

Frequently Asked Questions

Who should conduct the workplace risk assessment?

The risk assessment should be conducted by someone competent — meaning they have the knowledge, training, and experience to identify hazards and evaluate risks. This can be your in-house safety officer, a trained risk management champion (as required for bizSAFE Level 2), or an external safety consultant. For complex work environments, engaging a professional consultant ensures thoroughness and compliance. Learn more in our safety officer course guide.

How often must risk assessments be reviewed?

By law, risk assessments must be reviewed at least once every three years. However, best practice is to review them annually and whenever there are significant changes to work processes, equipment, or staffing. After any workplace incident, an immediate review of the relevant risk assessment is essential.

What happens if we do not have a risk assessment?

Operating without a risk assessment is a breach of the Workplace Safety and Health (Risk Management) Regulations. Penalties include fines of up to SGD 200,000 for companies and up to SGD 30,000 for individuals (e.g., company directors). More importantly, the absence of risk assessments puts your workers at genuine risk of injury or illness.

Can we do risk assessments ourselves or do we need a consultant?

Small businesses with simple operations can conduct basic risk assessments in-house, provided the assessor is competent. However, for comprehensive assessments — especially in higher-risk industries like construction, manufacturing, or chemicals — engaging a qualified workplace safety consultant ensures nothing is missed and your assessment meets regulatory standards.
