  86. Power to exempt public institutions 
  The State Government may exempt, subject to such conditions as
  
  it may consider necessary, any workshop or workplace where a manufacturing
  
  process is carried on and which is attached to a public institution, maintained
  
  for the purposes of education, 98[training, research] or
  
  reformation, from all or any of the provisions of this Act:
  PROVIDED  that no exemption shall be granted from the
  
  provisions relating to hours of work and holidays, unless the persons having
  
  the control of the institution submit, for the approval of the State
  
  Government, a scheme for the regulation of the hours of employment, intervals
  
  for meals, and holidays of the persons employed in or attending the institution
  
  or who are inmates of the institution, and the State Government is satisfied
  
  that the provisions of the scheme are not less favorable than the corresponding
  
  provisions of this Act.
