Introduction

The medical examiner should bear in mind that it is not possible to develop a comprehensive list of fitness criteria covering all possible conditions and the variations in their presentation and prognosis. The principles underlying the approach adopted in the table are often capable of being extrapolated to conditions not covered by it. Decisions on fitness when a medical condition is present depend on careful clinical assessment and analysis, and the following points need to be considered whenever a decision on fitness is taken:

• Medical fitness, comprising of physical and psychological fitness, means not suffering from any disease or disability which makes the person serving on board an inland craft unable to do either of the following:

  a)

  execute the tasks necessary to operate the craft,

  b)

  perform assigned duties at any time,

  c)

  perceive correctly the environment.

• The medical conditions listed are common examples of those that may render crew members unfit. The list can also be used to determine appropriate limitations on fitness. The criteria given can only provide guidance for physicians and shall not replace sound medical judgement.

• The implications for working and living on inland waters vary widely, depending on the natural history of each condition and the scope for treatment. Knowledge about the condition and an assessment of its features in the individual being examined shall be used to reach a decision on fitness.

• Where medical fitness cannot be fully demonstrated, mitigation measures and restrictions may be imposed on the condition of equivalent navigation safety. A list of mitigation measures and restrictions is added to the notes of this text. Where necessary, references to those mitigation measures and restrictions are made in the descriptions of the medical fitness criteria.

The table is laid out as follows:

Column 1: WHO International classification of diseases, 10th revision (ICD-10). Codes are listed as an aid to analysis and, in particular, international compilation of data.

Column 2: The common name of the condition or group of conditions, with a brief statement on its relevance to work on inland waterways.

Column 3: The medical fitness criteria that lead to the decision: incompatibility.

Column 4: The medical fitness criteria that lead to the decision: able to perform assigned duties at any time.

There are two appendices:

Appendix 1 Relevant criteria for vision as meant under diagnostic code H 0059

Appendix 2 Relevant criteria for hearing as meant under diagnostic code H 68-95.

Appendix 1 Relevant vision criteria as meant under diagnostic code H 0059

Minimum eyesight criteria:

1. Daytime visual acuity:

Acuity of both eyes together or of the better eye with or without correction greater than or equal to 0.8. Monocular vision is accepted.

Manifest double vision (motility) which cannot be corrected is not accepted. In the event of monocular vision: normal motility of the good eye.

Restriction 01*** may be indicated.

2. Eyesight at dawn and dusk:

To be tested in case of glaucoma retinal disorders or media opacities (e.g. cataract). Contrast sensitivity at 0.032 cd/m² in the Absence of glare; test result 1:2.7 or better as tested with the mesotest.

3. Field of view:

At least one eye shall meet the visual acuity standard and have the visual field without pathological scotomata. Formal testing by an eye doctor is mandatory if any abnormalities are found during the initial test or in case of glaucoma or retinal dystrophy.

4. Colour sense for deck crew members with navigational duties:

The colour sense is considered to be adequate if the candidate passes the Ishihara 24 plate edition test with a maximum of two mistakes. If the candidate does not pass this test, one of the mentioned approved alternative tests have to be performed. In case of doubt, a test with an anomaloscope shall be performed. The anomaloscope quotient shall be between 0.7 and 1.4 and thus exhibit normal trichromacy.

The approved alternative tests to the Ishihara plates are:

a)

b)

Kuchenbecker-Broschmann (maximum of two mistakes);

c)

HRR (minimum result ‘mild’);

d)

TMC (minimum result ‘second degree’);

e)

Holmes Wright B (result with a maximum of 8 errors for small);

f)

Farnsworth Panel D 15 test (minimum result: maximum one diametrical crossing in the plot of the arrangement of colours);

g)

Holders of boatmaster’s certificates issued in accordance with Council Directive 96/50/EC(1) whose anomaloscope quotient for colour sense is between 0,7 and 3,0 are deemed fit if their certificate has been issued before 1 April 2004.

The use of filter glass optical correction for colour sense, such as tinted contact lenses and glasses, is not allowed.
