Workplace Risk Assessment Singapore: Complete Step-by-Step Guide 2026

What Is a Workplace Risk Assessment?

A workplace risk assessment is a systematic process of identifying hazards in the workplace, evaluating the risks associated with those hazards, and implementing control measures to eliminate or minimise those risks. In Singapore, workplace risk assessments are a legal requirement under the Workplace Safety and Health Act.

Why Is Risk Assessment Important?

Risk assessment is the foundation of workplace safety. Without it, hazards go unidentified and workers remain exposed to preventable risks. Here is why every Singapore business needs proper risk assessments:

• Legal requirement — the Workplace Safety and Health Act mandates that employers assess and manage workplace risks
• Prevents accidents — identifying hazards before they cause injuries or fatalities
• Reduces costs — workplace injuries cost Singapore businesses millions in medical bills, lost productivity, and insurance claims
• bizSAFE requirement — risk assessments are mandatory for bizSAFE Level 3 and above
• Insurance benefits — proper risk assessments can reduce your work injury compensation insurance premiums

Types of Workplace Risk Assessments

Different work activities require different types of risk assessments:

1. General Workplace Risk Assessment

Covers common workplace hazards such as slips, trips, falls, ergonomic issues, and electrical safety. Required for all workplaces.

2. Activity-Based Risk Assessment

Focuses on specific work activities like working at height, hot work (welding, cutting), confined space entry, and lifting operations.

3. Chemical Risk Assessment

Required when workers handle hazardous chemicals. Covers exposure risks, storage requirements, and emergency procedures.

4. fire safety consultant Singapore

Evaluates fire hazards, escape routes, fire detection and suppression systems, and emergency evacuation procedures.

5. Noise Risk Assessment

Required in workplaces where noise levels exceed 85 decibels. Covers exposure limits and hearing protection measures.

How to Conduct a Workplace Risk Assessment

Follow these 5 steps to conduct a thorough risk assessment:

Step 1: Identify Hazards

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

• Physical workplace inspection
• Reviewing accident and incident reports
• Consulting workers about hazards they have observed
• Checking equipment manuals and safety data sheets
• Reviewing industry-specific hazard checklists

Step 2: Determine Who Might Be Harmed

Consider all people who could be affected:

• Full-time and part-time employees
• Contractors and subcontractors
• Visitors and delivery personnel
• Members of the public
• Vulnerable groups (new workers, pregnant women, young workers)

Step 3: Evaluate the Risks

For each hazard, assess the risk using a likelihood vs severity matrix:

• Likelihood: how likely is the hazard to cause harm? (rare, unlikely, possible, likely, almost certain)
• Severity: how serious would the harm be? (minor, moderate, major, critical, catastrophic)
• Risk level: combine likelihood and severity to determine if the risk is low, medium, high, or extreme

Step 4: Implement Control Measures

Use the hierarchy of controls to manage risks (in order of effectiveness):

1. Elimination — remove the hazard entirely
2. Substitution — replace with something less hazardous
3. Engineering controls — physical barriers, ventilation, guarding
4. Administrative controls — procedures, training, signage, job rotation
5. Personal Protective Equipment (PPE) — last resort, protect the individual

Step 5: Record, Review, and Update

Document your risk assessment and review it regularly:

• Record all findings in writing
• Communicate results to all workers
• Review at least once a year or when changes occur
• Update after any workplace accident or near-miss

Risk Assessment for bizSAFE Certification

If you are pursuing bizSAFE certification, risk assessments are critical at Level 3 and above. The bizSAFE risk assessment must:

• Follow the Workplace Safety and Health Council-approved format
• Be conducted by a trained Risk Management Champion (bizSAFE Level 2)

Common Risk Assessment Mistakes

• Generic assessments — using templates without customising to your actual workplace
• Not involving workers — workers know the hazards best, always consult them
• One-time exercise — risk assessments must be living documents, reviewed regularly
• Ignoring near-misses — near-misses are warnings of future accidents
• Focusing only on physical hazards — do not forget ergonomic, chemical, biological, and psychosocial risks
