Risk Assessment: Fatigue¶

Document Reference: RA_HO_18 Issue Date: 04/05/2026 Review Date: 04/05/2027 Assessed By: Sean Ashton (HSQE Consultant) Approved By: Aaron Mason, Managing Director

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

Severity (S): 1 = Minimal · 2 = Minor · 3 = Significant · 4 = Major · 5 = Catastrophic Likelihood (L): 1 = Rare · 2 = Unlikely · 3 = Possible · 4 = Likely · 5 = Almost certain Risk (R): S × L

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

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.
