Free workstation vibration exposure calculator. Estimate normalized and protection-adjusted exposure from vibration magnitude (m/s²), hours per day, tool/surface type, and anti-vibration support — then get Low / Moderate / High risk. Pair with RSI risk calculator for combined hand-load planning.

Normalized Exposure
2.91
Adjusted Exposure
2.56
Risk Level
High
High vibration exposure estimated. Reduce daily duration, improve damping support, and review task rotation controls.
Planning aid only. Validate exposure controls with occupational safety standards and on-site measurements.
We can build and embed a custom version of Workstation Vibration Exposure Calculator for your brand and workflow.
Answers: hand-arm vibration risk from power tools, how hours affect daily dose, and whether anti-vibration controls move exposure into a lower band.
Magnitude, √(hours/8), and surface multiplier combined.
Basic (−12%) or enhanced (−26%) anti-vibration support applied.
Low, Moderate, or High with actionable control guidance.
Default: 2.4 m/s² · 6 h/day · power tool (×1.4) · basic dampening (×0.88) → 2.4 × √(6/8) × 1.4 = 2.91 normalized → 2.56 adjusted · High risk.

| Contact type | Multiplier | Typical scenario | Example |
|---|---|---|---|
| Desk / keyboard | ×0.80 | Low-magnitude seated office contact | 0.3 m/s² · 8 h → norm ~0.24 |
| Power tool | ×1.40 | Grinders, drills, sanders — hand-arm vibration | 2.4 m/s² · 6 h → norm ~2.91 |
| Vehicle seat | ×1.10 | Forklift, delivery van, mobile machinery | 1.5 m/s² · 4 h → norm ~1.17 |
| Industrial platform | ×1.25 | Standing on vibrating machine base | 3.5 m/s² · 8 h → norm ~4.38 |
| Support level | Factor | Reduction | Note |
|---|---|---|---|
| None | ×1.00 | 0% | Baseline — no gloves, pads, or isolation |
| Basic dampening | ×0.88 | 12% | AV gloves, basic mat or grip |
| Enhanced dampening | ×0.74 | 26% | Engineered isolation, seat suspension, tool dampers |
| Adjusted score | Level | Typical action |
|---|---|---|
| Under 1.0 | Low | Maintain controls; re-check when tools or hours change |
| 1.0 – 2.49 | Moderate | Improve dampening, breaks, and task rotation |
| 2.5 and above | High | Reduce duration, upgrade controls, seek occupational hygiene review |
Hand-arm vibration (HAV) and whole-body vibration (WBV) depend on magnitude, frequency, direction, and contact time. This calculator compresses those into a planning score — formal assessments use weighted A(8) values per ISO 5349-1 (HAV) and ISO 2631-1 (WBV).

Adjusted 2.91 vs 2.56 with basic — High either way at these inputs.
Adjusted drops 2.56 → 2.15 (High → Moderate).
Normalized 2.75 · adjusted 2.42 · Moderate.
Adjusted 0.24 · Low — typical seated office profile.
Normalized 1.17 · adjusted 0.87 · Low.
Adjusted 4.38 · High — prioritize engineering isolation and time limits.
Adjusted 1.05 · Moderate — improve breaks before hours increase.
Adjusted 0.56 · Low — duration control keeps dose down.
