No vessel shall be fumigated until the captain or other commanding officer shall have mustered the crew and caused the members thereof and all other persons therein or thereon to leave and remain away from such vessel during the process of fumigation. Provided, however, that where a part of a vessel is to be fumigated and such part is not occupied or immediately adjoining an occupied portion of the vessel, and where after an investigation conducted by the commissioner of buildings, it appears that such portion may be fumigated without danger to life or health, he may, in his discretion, grant permission to the holder of a permit to perform fumigation without requiring all persons in other parts of such vessel to leave the same, subject to such conditions and restrictions as he may impose.
