# Safety Risk Assessment

## Overview
Risk assessment methodology for identified hazards including likelihood and severity evaluation, risk level calculation using organisational risk matrix, assessment of residual risk after controls. Primary agents: HSE Safety Manager, RAMS Review Specialist.

## Steps
1. **Likelihood Assessment** → Evaluate probability of occurrence based on frequency, exposure, historical data, and controls in place (ratings: Rare, Unlikely, Possible, Likely, Almost Certain)
2. **Severity Assessment** → Evaluate potential impact if hazard materialises based on severity of harm (ratings: Insignificant, Minor, Moderate, Major, Catastrophic)
3. **Initial Risk Calculation** → Combine likelihood × severity using organisational risk matrix to determine initial risk level
4. **Control Assessment** → Evaluate adequacy of proposed control measures using hierarchy of controls
5. **Residual Risk Calculation** → Recalculate risk level after proposed controls applied
6. **Risk Acceptance Decision** → Compare residual risk against organisational risk tolerance and determine acceptability
7. **Documentation** → Record all assessments with rationale for decisions

## Success Criteria
- All identified hazards assessed with consistent methodology
- Risk ratings accurately reflect the hazard profile
- Controls reduce risk to acceptable levels
- Residual risk documented and accepted by appropriate authority

## Common Pitfalls
1. Inconsistent rating application → Use standard definitions and examples
2. Overly conservative ratings → Can waste resources on low real-risk items
3. Missing cumulative risk → Multiple hazards combined may create higher risk
4. Controls not reducing risk to acceptable level → Residual risk still too high
