Tier 3 is a hands-on clinical assessment carried out by a qualified occupational health professional, triggered when a Tier 1 or Tier 2 questionnaire response indicates new or worsening symptoms. It looks at grip strength, sensory function and reported symptoms in more detail than the questionnaire alone allows.
Tier 4 is a formal diagnostic examination by a doctor, used where Tier 3 findings need a clinical diagnosis and staging against the modified Stockholm Workshop Scale. This is also the tier used to give an opinion on fitness for continued vibration-exposed work once a diagnosis has been made.
Who this is for
- Workers flagged by a Tier 1/2 questionnaire for new or worsening symptoms
- Workers already diagnosed with HAVS or vibration white finger, needing continued surveillance
- Employers needing a documented clinical opinion before deciding on a worker's continued vibration exposure
What's included
Tier 3: a clinical assessment of grip strength, sensory function and symptom history, carried out by a qualified occupational health professional. Tier 4, where indicated: a formal examination and diagnosis by a doctor, staged against the modified Stockholm Workshop Scale, with a written opinion on fitness for continued vibration work and any recommended controls or restrictions.
