Fatigue risk management system (FRMS)
A fatigue risk management system (FRMS) is a documented, risk-based approach to managing fatigue across an organisation. It provides structure beyond ad hoc roster changes or reactive incident response.
FRMS is widely referenced in transport and other safety-critical sectors, but the underlying principles apply wherever shift work, long hours, or circadian disruption create fatigue-related risk.
Core components
Section titled “Core components”A typical FRMS includes:
| Component | Purpose |
|---|---|
| Governance | Defines roles, accountability, and decision authority |
| Policy | Sets organisational expectations on rest, hours, and reporting |
| Risk assessment | Identifies fatigue hazards and evaluates controls |
| Controls | Roster design, rest rules, monitoring, and worker engagement |
| Assurance | Audits, reviews, and continuous improvement |
| Training | Ensures staff understand fatigue risks and reporting routes |
FRMS vs compliance checklists
Section titled “FRMS vs compliance checklists”A checklist approach may verify that rest periods exist on paper. An FRMS aims to manage fatigue risk in live operations — accounting for actual workload, disruption, commuting, and individual factors.
FRMS should be proportionate to the organisation’s risk profile. A small logistics depot and a national rail operator will need different levels of formality, but both benefit from clear governance.
Implementation considerations
Section titled “Implementation considerations”When establishing or reviewing an FRMS:
- Engage operational staff, safety representatives, and competent persons early
- Align with existing safety management systems rather than creating parallel bureaucracy
- Define measurable indicators — such as overtime patterns, reportable fatigue events, and roster stability
- Plan for periodic review as operations, contracts, or workforce change
