Task/Activity¶
Work-related fatigue arising across AMWS operations: long driving days to sites, overnight stays, emergency call-outs, end-of-shift physical work, and the interaction between long days and high-vibration tool use.
Location¶
All AMWS work locations — yard, road, site, overnight accommodation.
Persons at Risk¶
- All operatives (especially those on emergency call-out rotation)
- Drivers (HGV grab and van fleet)
- Site Supervisor and Team Leaders (extended decision-making days)
- Lone workers performing late-finish or early-start jobs
Hazards and Controls¶
| Hazard | Existing Controls | S | L | R | Additional Controls | S | L | R |
|---|---|---|---|---|---|---|---|---|
| Driver fatigue → road traffic accident | Drivers' hours rules observed; in-cab telematics; SOP 8.13 Driving; mobile phone hands-free policy | 4 | 3 | 🔴 12 | Mandatory 11-hr daily rest; max 9-hr driving day except emergency; weekly hours review by Aaron Mason; refresher driver-fatigue training in TBT-2026-09 | 3 | 1 | 🟢 3 |
| Cumulative fatigue from emergency call-out rotation | On-call rota across multiple operatives; emergency call-outs logged; SOP 5.4 Emergency Preparedness | 3 | 3 | 🟡 9 | Maximum 1-in-4 on-call frequency; rest day after a >4-hr night call-out; rota visibility on whatsapp works group | 2 | 2 | 🟢 4 |
| Fatigue interaction with HAVS exposure (long day + high-vibration tool) | SOP 8.10 HAVS; trigger-time monitoring; rotation between operatives | 3 | 3 | 🟡 9 | Cap trigger time at 75% of EAV (1.9 m/s² A(8)) on days >10 hrs on site; mandatory rotation after 60 min continuous breaker work | 2 | 1 | 🟢 2 |
| Cognitive fatigue → near-miss / poor decision (excavation, confined space) | RAMS sign-off; toolbox talks; supervisor presence | 4 | 2 | 🟡 8 | Permit-to-work issuer must be at start of shift, not 8 hours in; high-risk activities not to start within last hour of shift | 3 | 1 | 🟢 3 |
| Lone-worker fatigue (no buddy for early-start / late-finish) | SOP 8.8 Lone Working; check-in protocol; RA_HO_04 | 3 | 2 | 🟡 6 | Buddy check-in mandatory for shifts >10 hrs or starting before 06:00; fatigue self-assessment at start of solo shift | 2 | 1 | 🟢 2 |
| Overnight accommodation poor rest → next-day fatigue | Pre-booked accommodation; meal allowance | 2 | 3 | 🟡 6 | Use only Travelodge / Premier Inn standard or above; no twin-share for overnight call-out rotation; no >2 consecutive nights away without rest day | 2 | 2 | 🟢 4 |
| Manager fatigue (Site Supervisor extended decision days) | Working hours informally tracked; weekly compliance call | 3 | 2 | 🟡 6 | Aaron Mason to monitor Jason May's working hours weekly; deputise to a Team Leader when supervisor day exceeds 11 hours | 2 | 1 | 🟢 2 |
PPE & Equipment Requirements¶
- Telematics in all fleet vehicles (already standard)
- In-vehicle break reminders configured
- Lone-worker check-in app (Reflex / equivalent) issued to operatives on early-start / late-finish rotation
Training Requirements¶
- Driver fatigue awareness — Toolbox talk TBT-2026-09 (Sept 2026) plus annual refresher
- HAVS awareness — Toolbox talk TBT-2026-06 (June 2026) with explicit fatigue interaction
- Lone-working briefing — Toolbox talk TBT-2026-11 (Nov 2026)
Emergency Procedures¶
- Driver suffering fatigue while driving: pull over to the next safe stopping place; notify Site Supervisor; do not continue. Cover arranged.
- Site fatigue concern: Site Supervisor stops work, returns operatives to yard or arranges rest break, decides whether to continue.
Monitoring & Review¶
- Weekly: Aaron Mason reviews drivers' hours from telematics
- Monthly: Site Supervisor reviews on-call rotation balance
- Quarterly: HSQE Consultant reviews this RA against any near-miss / fatigue-attributed incidents from APP_22
- Annual: Full RA review — by 04/05/2027

Risk Scoring Matrix (4 × 4)¶
- Severity (S): 1 = Negligible · 2 = Minor · 3 = Serious · 4 = Catastrophic
- Likelihood (L): 1 = Remote · 2 = Unlikely · 3 = Likely · 4 = Almost Certain
- Risk Rating (R = S × L): 🟢 Low (1-5) · 🟡 Medium (6-11) · 🔴 High (12-16)
This RA uses the same 4 × 4 matrix applied across APP_07, APP_08 and all sister RAs for auditor consistency.
How this document is approved
This document is maintained under AMWS's continuous-compliance model. Substantive revisions are reviewed and signed off by the Directors at the standing weekly Director / HSQE compliance call (Sean Ashton, Onyx + Leanne Mason). Currency, cross-references and minor edits are checked at the monthly Onyx site visit. The annual Management Review (September) provides the strategic-level confirmation. Compliance is therefore continuous, not gated on a single annual meeting.
