161. Where a Board is, upon the advice of the Health Officer, of opinion that the cleansing and disinfection of any building or part of a building in the cantonment or of any articles in any such building or part which are likely to retain infection, or the renewal of the flooring of any such building or part of such building, would tend to prevent or check the spread of any infectious or contagious disease, he may, by notice in writing, require the owner or occupier to cleanse and disinfect the said building, part or articles, as the case may be, or to renew the said flooring, within such time as may be specified in the notice: Provided that where, in the opinion of the Board, the owner or occupier is from poverty or any other cause unable effectually to carry out any such requisition, the Board may, at the expense of the cantonment fund, cleanse and disinfect the building, part or articles, or, as the case may be, renew the flooring.
