Health and Safety Risk Assessment: Identifying Hazards and Managing Risks
Health and safety risk assessment and management is one of the most important parts of an effective workplace safety program. Every workplace contains hazards that could potentially cause injury, illness, property damage, or environmental harm.
For employers and HSE professionals, the objective is to identify these hazards, determine who could be harmed, evaluate the level of risk, and introduce suitable control measures to prevent or reduce harm.
A risk assessment is not simply a form that needs to be completed. It is a practical process for understanding workplace hazards and making sure appropriate controls are actually implemented.
What Is a Health and Safety Risk Assessment?
A health and safety risk assessment is a systematic process used to identify hazards, determine who may be exposed, evaluate the associated risks, and establish appropriate control measures.
In simple terms, a risk assessment should answer these questions:
- What could cause harm?
- Who could be harmed?
- How could they be harmed?
- What controls are already in place?
- Is the existing level of risk acceptable?
- What additional controls are required?
- Who is responsible for implementing them?
- When should the controls be reviewed?
Why Is Risk Assessment Important?
Workplace accidents do not always happen without warning. Many incidents occur because hazards were not identified, existing controls were inadequate, or known problems were not corrected.
- Identify workplace hazards
- Prevent injuries and occupational illnesses
- Protect employees and other people
- Improve workplace safety
- Identify weaknesses in existing controls
- Reduce accidents and near misses
- Improve emergency preparedness
- Support legal and regulatory compliance
- Establish clear responsibilities for safety actions
- Improve the overall HSE management system
Step 1: Identify Workplace Hazards
The first step in risk assessment is hazard identification. A hazard is anything that has the potential to cause harm.
Walk around the workplace and look at how work is actually being performed. Consider machinery, equipment, chemicals, materials, people, workplace conditions, and work processes.
Common Workplace Hazards
- Slips, trips, and falls
- Working at height
- Electrical hazards
- Moving machinery
- Fire and explosion
- Hazardous chemicals
- Manual handling
- Workplace dust
- Excessive noise
- Poor housekeeping
- Vehicle movement
- Ergonomic hazards
- Poor ventilation
- Unsafe work practices
- Workplace stress
Look at How Work Is Actually Performed
Written procedures do not always show what happens during actual work. For this reason, HSE professionals and supervisors should observe workers while tasks are being performed.
- How are employees using equipment?
- Are machines being operated according to procedures?
- Are workers using appropriate PPE?
- Are tools suitable for the task?
- Are walkways and emergency exits clear?
- Is housekeeping adequate?
- Are workers lifting heavy or awkward loads?
- Are chemicals being handled correctly?
- Are there unsafe shortcuts or work practices?
Use Accident and Near-Miss Records
Previous incidents can provide useful information during a risk assessment. Review accident reports, near-miss reports, first-aid records, incident investigation reports, occupational illness records, inspection reports, employee complaints, and maintenance records.
Consider Health Hazards
Risk assessment should not focus only on accidents. Some workplace hazards can cause health problems gradually through repeated or prolonged exposure.
Manual Handling
Repeated or heavy lifting can contribute to musculoskeletal injuries.
Chemical Exposure
Chemicals may cause burns, poisoning, respiratory problems, skin irritation, or other health effects depending on their properties and exposure conditions.
Dust Exposure
Workplace dust can create respiratory and occupational health concerns.
Noise
Long-term exposure to excessive noise can contribute to hearing damage.
Ergonomic Hazards
Poor workstation design, repetitive movements, awkward postures, and prolonged sitting or standing can contribute to musculoskeletal problems.
Work-Related Stress
Excessive workload, poor work organization, lack of support, or other workplace factors may contribute to work-related stress.
Identify Who Might Be Harmed
After identifying the hazards, determine who could be harmed and how.
- Employees
- Contractors
- Maintenance workers
- Temporary workers
- Visitors
- Drivers
- Cleaners
- Security personnel
- Other members of the public
Different groups may experience different levels of exposure to the same hazard.
Consider Vulnerable Workers
Some people may require additional consideration during risk assessment, including pregnant workers, young workers, new employees, inexperienced workers, workers with disabilities, temporary workers, and workers performing unfamiliar tasks.
Consult Workers
Workers are an important source of safety information because they understand how tasks are performed in practice.
HSE professionals and supervisors should encourage workers to report unsafe conditions, near misses, equipment problems, difficult tasks, repetitive activities, unsafe procedures, potential hazards, and suggestions for improving safety.
Step 2: Evaluate the Risk
Once hazards have been identified, the next step is to evaluate the associated risk. Risk generally considers two important factors: likelihood and severity.
Organizations may use different risk assessment methodologies depending on their activities.
- HIRA – Hazard Identification and Risk Assessment
- JSA – Job Safety Analysis
- JHA – Job Hazard Analysis
- FMEA – Failure Mode and Effects Analysis
- Risk Matrix
- Task Risk Assessment
Step 3: Identify Existing Controls
Before adding new controls, identify what is already being done to manage the hazard.
- Machine guarding
- Engineering controls
- Ventilation
- Safety procedures
- Training
- Warning signs
- Preventive maintenance
- Inspections
- Emergency arrangements
- Permit-to-work systems
- Personal protective equipment
The effectiveness of each control should be verified in the workplace rather than assumed from written procedures alone.
Step 4: Implement the Hierarchy of Controls
The Hierarchy of Controls provides a useful framework for selecting risk control measures.
1. Elimination
Remove the hazard completely where reasonably practicable.
2. Substitution
Replace a hazardous material, process, or equipment with a safer alternative.
3. Engineering Controls
Use physical or technical measures to separate workers from the hazard, such as machine guards, barriers, interlocks, local exhaust ventilation, automatic shutdown systems, and guardrails.
4. Administrative Controls
Control how work is organized and performed through safe operating procedures, training, job rotation, warning signs, permit-to-work systems, inspection programs, and work instructions.
5. Personal Protective Equipment
PPE can provide additional protection when risks remain. Examples include safety helmets, safety shoes, safety glasses, gloves, hearing protection, respiratory protection, and protective clothing.
Step 5: Record the Risk Assessment
Risk assessment records should clearly communicate the identified hazards, existing controls, additional actions, and responsible persons.
| Element | Description |
|---|---|
| Process/Activity | Work being performed |
| Hazard | Potential source of harm |
| Potential Consequence | Possible result |
| Persons at Risk | People who may be affected |
| Existing Controls | Current safety measures |
| Initial Risk | Risk before additional controls |
| Additional Controls | Further measures required |
| Responsibility | Person responsible |
| Target Date | Required completion date |
| Residual Risk | Risk remaining after controls |
Step 6: Implement and Monitor Corrective Actions
Identifying additional controls is only part of the process. Required actions should be assigned to responsible persons and tracked until completion.
Example: Exposed electrical wiring may create a risk of electric shock or fire. The corrective action could include repairing or replacing damaged wiring and providing suitable protection. The responsible department should complete the action within the defined target date, followed by HSE verification.
Step 7: Review the Risk Assessment
A risk assessment should not be treated as a document that is completed once and then forgotten.
It should be reviewed when significant changes occur, including new machinery or equipment, new chemicals, changes in production processes, workplace layout changes, new work activities, staffing changes, building modifications, or changes in working methods.
It should also be reviewed following accidents, incidents, near misses, employee concerns, inspection findings, or identification of new hazards.
Risk Assessment After an Accident or Near Miss
An accident or near miss should trigger a review of the relevant risk assessment. Ask what happened, what hazard contributed to the event, whether existing controls were effective, whether procedures were followed, whether adequate training was provided, whether the event could happen again, and what additional controls are required.
Risk Assessment Is More Than Paperwork
One of the most important principles of health and safety risk management is that safety is about actions, not paperwork.
A completed risk assessment has little value if workers continue to be exposed to uncontrolled hazards.
Identify → Assess → Control → Implement → Monitor → Review
This cycle should become part of normal workplace operations.
Simple Risk Assessment Example
Hazard: Uneven walking surface.
Potential Risk: A worker could trip and suffer an injury.
Persons at Risk: Employees, contractors, and visitors.
Existing Controls: Warning sign and routine housekeeping.
Additional Controls: Repair the damaged floor and maintain the walkway in a safe condition.
Monitoring: Conduct routine workplace inspections to verify that the walkway remains clear and in good condition.
Common Mistakes in Workplace Risk Assessment
1. Treating Risk Assessment as Paperwork
Completing a form without implementing controls does not reduce risk.
2. Ignoring Workers
Workers can provide valuable information about hazards and practical solutions.
3. Focusing Only on Accidents
Occupational health hazards can develop gradually and should also be considered.
4. Relying Only on PPE
Higher-level controls should be considered before relying solely on PPE.
5. Not Reviewing Risk Assessments
Changes in equipment, processes, people, or workplace conditions can introduce new risks.
6. Failing to Track Corrective Actions
An identified hazard should have a clear action, responsible person, and target date where further controls are required.
Final Thoughts
Effective health and safety risk assessment and management is a continuous process that helps organizations identify hazards, evaluate risks, implement controls, and protect people from harm.
A good risk assessment should answer a simple question:
What can cause harm, and what are we doing to prevent it?
Employers, supervisors, and HSE professionals should regularly inspect their workplaces, involve workers, review existing controls, and take action when hazards are identified.
Risk assessment is not about filling out forms. It is about identifying hazards, controlling risks, and protecting people.
