Mobility – operators should have full movement of the trunk, neck and limbs and possess normal agility. Adjustments for individuals with disabilities should be considered where reasonably practicable. Drug/alcohol dependence – an individual who is dependent on alcohol or non-prescribed drugs should NOT be employed as a driver. Where there is a history of dependence DVLA guidance applies. Mental health – a history of previous mental illness should not necessarily preclude selection but where there is suspicion of, or knowledge of a psychiatric disorder which may be impacting on their behaviour or judgement, an operator should be barred from vehicle operation until medical assessment has been made and fitness judged against the relevant guidelines. Vision – the operator should have good judgement of space and distance – generally this requires effective use of both eyes, although monocular vision will not necessarily exclude an individual as certain kinds of driving work can be performed satisfactorily.Distance vision should be the same standard for driving a car on public roads. Hearing – the ability to hear instructions and warning signs is important but if the individual demonstrates on risk assessment that the deafness does not constitute a hazard it should not disqualify him/her. Epilepsy – if an operator has epilepsy but is eligible for a driving licence under the DVLA rules, then he/she should not be disqualified. Diabetes mellitus – usually causes no problems if well controlled by diet or tablets. Neurological or Cardiac problems – detailed guidance from the DVLA is used. Disorders of the balance – uncontrolled vertigo and disorders of balance will bar an individual from vehicle operation.Fitness to operate fork trucks may be impaired by the effects of medication whether prescribed or purchased over the counter. Operators should seek advice from the GP or pharmacist and inform their employer about any potential effects the medication may have on their ability to operate vehicles safely.
