[接上页] 5 Very few merchant ships carry doctors on board nowadays. Acute illness or injury is dealt with by designated ships' officers whose training is limited to first aid or medical aid treatment. It should also be borne in mind that the size of a crew complement is carefully adjusted. Sickness can throw a burden on other crew members or even impair the efficient working of a ship. An approved medical practitioner should therefore be satisfied that no condition is present in the applicant which is likely to cause trouble during a voyage and that no treatment is being followed which might cause worrying side effects. It would be unsafe practice to permit a seafarer to serve at sea suffering from a medical condition in which serious exacerbation requiring expert treatment could occur. 6. The absence of a doctor in most merchant ships also means that seafarers will not be able readily to consult a doctor or to obtain special treatment until the next port of call. Ship turnaround in ports is often very rapid, allowing no time for necessary investigation subsequent to consultation with a doctor. The standard of medical practice varies from port to port also and necessary medical facilities may not be available at the smaller, more remote ports. It is doubtful if it is ever wise to permit a seafarer to serve at sea if the loss of a necessary medicament could precipitate the rapid deterioration of a medical condition. 7. Special care should be taken when examining an applicant who- (a) has a doubtful medical history; (b) is likely to spend long periods in tropical climates; (c) is likely to join ships by air travel; or (d) has recently served or is intending to serve on bulk chemical carriers. Notes: (1) In addition to symptoms caused by acute conditions such as catarrh of the ear and sinuses (baratrauma), air transport sometimes leads to other disabilities such as breathlessness, dizziness, etc. becoming manifest. Such cases will require further investigation since the findings may well reflect on the applicant's suitability for further unrestricted sea service. (2) An applicant in category (d) above should be subjected to a blood test in addition to other medical examination procedures. 8. Physical requirements may vary between different types of ships, their departments and individual jobs in them. However, all seafaring jobs need an acceptable degree of fitness, in accordance with these standards, which is uniform for all shipping trades. The imposition of a restriction under section 6(2) of this Regulation may serve to avoid a particular type of trade or a prolonged voyage where there is some specified medical contra-indication, but careful consideration is necessary before any restriction is imposed. The type of restriction and the length of time for which it will operate should be made clear. The requirements of an advised treatment regime should never be set aside. 9. Despite the shortness of the voyage, even coastal work can be arduous and uncomfortable. A restriction to that type of work should be considered as an alternative to refusal of a certificate only if the shortness of voyage will permit adequate treatment of the medical condition causing concern. Examination Procedures 1. When it is necessary to consult with other doctors the usual professional ethical considerations will appertain, but it should be clearly understood that the final decision on fitness in accordance with the required medical and visual standards rests with the approved medical practitioner, subject to the provisions of section 9(2) of this Regulation. 2. An applicant for a medical fitness certificate shall be placed in one of the following categories by reference to the category letter ascribed in these Standards to any medical condition diagnosed in respect of him- A. Fit for sea service without restriction. B. Permanently unfit for sea service. C. Indefinitely unfit for sea service. D. Temporarily unfit for sea service. E. Fit for sea service subject to restriction.An applicant in respect of whom no adverse medical condition is diagnosed shall be placed in category A. 3. (1) An applicant placed in category A shall be granted a medical fitness certificate without restriction, but subject to the maximum period of validity specified in section 8 of this Regulation. (2) An applicant placed in category B shall be refused a medical fitness certificate. Any medical fitness certificate in his possession shall be cancelled. (3) An applicant placed in category C shall be refused a medical fitness certificate and informed that he may apply for a further examination after a specified number of months. Any medical fitness certificate in his possession shall be suspended until such further examination. (4) An applicant placed in category D shall be refused a medical fitness certificate and informed that he may apply for a further examination after a specified number of weeks. Any medical fitness certificate in his possession shall be suspended until such further examination. |
