Hand-Arm Vibration VR Training: Tool Selection, Trigger Time and Symptoms (Control of Vibration at Work Regulations 2005)
VR hand-arm vibration scenario on the Control of Vibration at Work Regulations 2005: exposure action and limit values, tool choice, trigger time and early symptom reporting.
QUICK ANSWER
The Control of Vibration at Work Regulations 2005 set a daily exposure action value of 2.5 m/s2 A(8) and a limit value of 5 m/s2 A(8) for hand-arm vibration, and require employers to reduce exposure and train workers. A VR scenario makes the learner pick tools and plan trigger time to stay inside the limits.
What the Rule Requires
Control of Vibration at Work Regulations 2005 (SI 2005/1093): for hand-arm vibration the daily exposure action value is 2.5 m/s2 A(8) and the daily exposure limit value is 5 m/s2 A(8). Employers must assess the risk, eliminate or reduce exposure to as low a level as reasonably practicable, ensure the limit is not exceeded, provide health surveillance where workers are at risk and give information, instruction and training.
The scenario is a demolition and breaking out job on a cold morning. The gang has an old breaker with worn mountings, a newer low-vibration model, a diamond drill that could avoid most breaking, and a worker who mentions tingling fingers at the end of last week.
Hazards in This Scenario
- Hand-arm vibration syndrome and carpal tunnel
- Cold and wet hands increasing risk
- Worn tools with higher vibration
- Ignored early symptoms
The Procedure the Scenario Rehearses
- Choose a method that avoids vibrating tools where possible
- Pick the lowest vibration tool for the job
- Plan trigger time within the daily points
- Maintain tools and replace worn parts
- Keep hands warm and dry
- Report tingling, numbness or white fingers early
Mistakes the Scenario Is Built to Catch
- Using the old breaker because it is nearer
- Ignoring trigger time
- Gripping too tightly
- Not reporting symptoms
Competence Assessment Matrix
| Decision point | What the assessor sees | Pass standard |
|---|---|---|
| Method | Alternative to breaking | Considered |
| Tool | Low-vibration model chosen | Lowest-vibration tool for the task |
| Trigger time | Daily plan | Within action and limit values |
| Symptoms | Report | Reported early |
What VR Covers
- Exposure points shown live
- Tool choice comparisons
- Symptom reporting practice
- Records per operative
What VR Does Not Replace
- Health surveillance by an occupational health provider
- Tool vibration data and maintenance
- Job rotation planning
Scope of a One-Scenario Pilot
A pilot builds this scenario as a single module, in Unity or Unreal Engine depending on the visual fidelity the task needs and the headsets on site. It runs on standalone headsets, logs every learner decision, and exports a per-person record for your training file. It is measured against your current method with a test cohort before anything is scaled.
Frequently Asked Questions
What are the UK vibration limits?
For hand-arm vibration, an action value of 2.5 m/s2 A(8) and a limit value of 5 m/s2 A(8).
What are early signs of HAVS?
Tingling, numbness and fingers going white, especially in the cold.
Is health surveillance required?
Yes, for workers likely to be exposed above the action value or who are at risk.
