50-74-215. Interior and exterior examination of boiler. (1) The inspector must satisfy himself by a thorough interior and exterior examination that the boilers are well-made and of good and suitable material; that the openings for the passage of water and steam, respectively, and all pipes and tubes exposed to heat are of the proper dimensions and free from obstructions; that the flues are circular in shape; that the fire line of the furnace is at least 2 inches below prescribed minimum waterline of the boilers; that the arrangements for delivering the feed water are such that the boilers cannot be injured thereby; and that such boilers and the steam connections may be safely employed without danger to life.
     (2) No boiler or steam pipe or any of the connections thereto which are made in whole or in part of bad material or are unsafe from any cause shall be approved. Nothing herein shall be construed to prevent the use of any boiler or steam generator, which may not be constructed of riveted iron or steel plates, when the inspector has satisfactory evidence that such boiler or steam generator is equal in strength to and as safe from explosion as boilers of the best quality, constructed of iron or steel plates.
