Why it matters
Without it, vibration and noise exposure can go unmanaged, increasing risk of occupational health issues and failing to document compliance or trigger necessary health surveillance decisions.
From design to safety
Design
AI guides survey and specification
AI reads planned equipment loads, maps exposure zones, defines hearing protection and health surveillance requirements, and integrates with the project brief; it cross checks the compatibility of chippers, stump grinders, MEWPs, and vehicles with site constraints, duty cycles, and access routes.
- vibration monitoring plan
- equipment catalog
- health surveillance policy
Build
Site setup and risk mapping
AI computes safe work methods, set-up order, exposure-control points, and crew task sequencing; it prescribes PPE choices, hearing protection types, and briefing notes, ensuring alignment with site access, traffic management, and utility clearance.
- site risk map
- PPE inventory
- maintenance schedule
Operation
Real-time exposure monitoring on site
AI streams sensor data for vibration magnitudes and noise levels, flags high-risk tasks, logs triggers with task context, and prompts live PPE reminders; it supports crew lead decisions with micro-adjustments to workflow.
- sensor network
- audio level meters
- noise dosimeter
Maintenance
Ongoing fit, function, and health review
AI analyzes sensor drift, recalibrates thresholds, and schedules equipment servicing and health surveillance reviews based on exposure data; it records calibration events, compares serial readings, and forecasts replacement timing.
- calibration logs
- equipment service records
- staff health records
Safety
Safeguards and regulatory reporting
AI flags breaches, maintains aerial rescue readiness, and compiles regulatory, insurer, and safety audit reports; it stores incident trails, ensures up-to-date training, and streamlines approvals for non-routine operations.
- rescue equipment status
- incident logging
- regulatory reporting

Worked example
Catching a seal leak before a charter
Illustrative scenario with sample data.
A mid-size tree contractor uses multiple chippers and MEWPs on a roadside project; AI tracks cumulative HAV exposure and noise dose for operators.
Signal in
sensor_id: S01, device: vibration_sensor, reading: 1.2g; device: dosimeter, level: 88dB; shift: 07:30-15:30; worker: Operator A
System out
exposure_summary: Operator A exceeded 8h dose; PPE reminder issued; task re-sequenced to reduce exposure; health surveillance flagged for audiometry.
Human sign-off: Safety officer reviews the alert, approves PPE adjustment, and confirms health surveillance scheduling.
How to roll it out
Phase 1
Weeks 1 to 4
Baseline sensor installation, threshold setting, and initial operator training across all active sites.
Phase 2
Weeks 5 to 12
Full data capture, automated alerts, and integration with health surveillance scheduling and reporting.
Phase 3
Weeks 13 to 24
Audit readiness, data quality checks, and process refinement for all machinery and hearing protection policies.
Where people stay in charge
- Decisions on exposure thresholds and health surveillance must be signed off by the qualified safety officer or equivalent regulator-approved professional.
- The system cannot override legally mandated PPE selection, fit testing, and immediate shutdowns; qualified professionals must authorize changes.
- Data handling that affects medical history or health records must be reviewed and approved by HR and the appointed clinical advisor.
Questions owners and crews ask
What hardware reads vibration and noise in tree work equipment?
Vibration sensors, handheld meters, and wearable dosimeters collect magnitudes and doses; data is ingested by the AI to compute exposure and trigger PPE guidance.
How does AI decide when to issue PPE reminders?
AI compares real-time readings against configured thresholds per task and worker role, then flags breaches and prompts immediate PPE checks and fit verifications.
Who signs off health surveillance actions generated by the system?
A qualified safety officer or clinical advisor reviews and authorizes audiology or health checks triggered by cumulative exposure data.
Can this system be integrated with regulatory reporting?
Yes, the system compiles exposure summaries, audit logs, and health surveillance records for inclusion in regulatory and insurer reports.
