What Is a Risk Assessment? (Definition)
A risk assessment is a structured process for identifying hazards, deciding who could be harmed and how, evaluating the level of risk, and selecting controls to prevent injury, illness, or damage. It is one of the core practices in occupational health and safety management.
In workplace safety, risk assessment underpins ISO 45001 systems, OSHA safety programmes, UK HSE guidance, method statements, permits to work, and day-to-day operational decision-making.
The 5 Steps of Risk Assessment
The UK HSE 5-step model is widely used because it is practical, auditable, and easy to apply across high-risk environments:
| Step | Action | Example |
|---|---|---|
| 1 | Identify hazards | Forklift-pedestrian interaction in a loading bay |
| 2 | Decide who might be harmed and how | Warehouse operators, drivers, visitors, or contractors could be struck |
| 3 | Evaluate risks and decide precautions | Add segregation, speed limits, proximity alerts, and supervision |
| 4 | Record findings and implement them | Update the risk register, method statement, and training plan |
| 5 | Review and update | Reassess after a near miss, layout change, or new equipment |
Risk Assessment Examples in Heavy Industry
Risk assessments can be task-based, area-based, equipment-based, or dynamic. Common industrial examples include:
-
Working at height on platforms, ladders, scaffolds, or rooftops
-
Forklift movement in shared pedestrian zones
-
Confined space entry, hot work, isolation, and maintenance activities
-
Manual handling, repetitive tasks, and ergonomic exposure
-
Chemical handling, dust, noise, heat, and energy release hazards
Risk Matrix and Hierarchy of Controls
Many organisations use a risk matrix to score likelihood × severity. This helps prioritise action, but it should not replace professional judgement, worker consultation, or evidence from incidents and near misses.
Once risk is evaluated, controls should follow the hierarchy of controls:
- Eliminate the hazard where possible
- Substitute with a safer process or material
- Use engineering controls such as guards, barriers, or segregation
- Apply administrative controls such as procedures, permits, training, and supervision
- Use PPE as the final line of defence
Why Risk Assessment Matters
Risk assessment is a legal and operational foundation for preventing harm. It helps organisations move from reactive incident response to proactive control of hazards before people are injured.
Strong risk assessment programmes help EHS teams:
- Demonstrate compliance with HSE, OSHA, and ISO 45001 expectations
- Prioritise high-severity and high-frequency risks
- Improve training, supervision, and safe systems of work
- Connect near misses, inspections, and corrective actions to prevention
How AI and Computer Vision Improve Risk Assessment
Traditional risk assessments often depend on periodic site walks, manual observation, and incident reports. AI-powered safety platforms like Safvr strengthen this process by turning real-world video evidence into continuous risk intelligence.
Computer vision can improve risk assessment by:
- Automatically identifying hazards such as line-of-fire exposure, blocked exits, missing PPE, and unsafe proximity
- Scoring recurring risk patterns by location, shift, task, and severity
- Detecting changes in behaviour or environment that were not visible during the original assessment
- Providing evidence for review meetings, audits, and corrective action planning
How Safvr Helps You Operationalise Risk Assessment
Safvr's AI-powered workplace safety platform helps EHS teams turn risk assessments into live, measurable controls. Instead of leaving findings in spreadsheets, Safvr detects hazardous conditions in real time and feeds insight back into prevention workflows. Key capabilities include:
- Automated hazard identification from existing camera feeds
- Risk scoring by zone, behaviour, equipment, and task
- Real-time alerts when controls fail or exposure increases
- Video evidence for risk reviews, investigations, and audits
- Trend dashboards that support ISO 45001 continual improvement
