  person or his parent or guardian accompanied by a document signed by the
  
  manager of a factory that such person will be employed therein if certified to
  
  be fit for work in a factory, or on the application of the manager of the
  
  factory in which any young person wishes to work, examine such person and
  
  ascertain his fitness for work in a factory.
  (2) The certifying surgeon, after examination, may grant to such
  
  young person, in the prescribed form, or may renew- 
  (a) a certificate of fitness to work in a

  fourteenth year, that he has attained the prescribed physical standards and
  
  that he is fit for such work;
  (b) a certificate of fitness to work in a
  
  factory as an adult, if he is satisfied that the young person has completed his
  
  fifteenth year, and is fit for a full day's work in a factory:
  PROVIDED  that unless the certifying surgeon has a
  
  personal knowledge of the place where the young person proposes to work and of
  
  the manufacturing process in which he will be employed, he shall not grant or
  
  renew a certificate under this sub-section until he has examined such place.

  regard to the nature of the work in which the young person may be employed, or
  
  requiring re-examination of the young person before the expiry of the period of
  
  twelve months.
  (4) A certifying surgeon shall revoke any certificate granted or
  
  renewed under sub-section (2) if in his opinion the holder of it is no longer
  
  fit to work in the capacity stated therein in a factory.
  (5) Where a certifying surgeon refuses to grant or renew a
  
  certificate or a certificate of the kind requested or revokes a certificate, he
