Section 11(1) in The Merchant Shipping (Crew Accommodation) Rules, 1960
(1)In every ship to which these rules apply every part of the crew accommodation, other than pantries, laundries drying rooms, lockers and storerooms, shall be properly lighted by natural light. Provided that if in any space in a passenger ship it is impracticable to provide proper natural lighting, such lighting shall not be required if adequate electric lighting is always available in that space. The Central Government may exempt any ship from the requirement of this sub-rule in relation to the sanitary accommodation and passageways to the extent that it is satisfied that compliance therewith is unreasonable or impracticable in the circumstances.
