284 ENGINEERS' LICENSE LAWS 



The owners or users of steam boilers or engines of a capacity 

 of not over 75 sq. ft. of heating surface, and a steam pressure 

 of not over 25 Ib. per sq. in., used for power only, and all boilers 

 under a pressure of 15 Ib. per sq. in. used for heating purposes 

 only, shall apply for a permit to employ a competent, careful, 

 and trustworthy person, instead of a licensed engineer; such 

 person to be recommended by two citizens, one of whom shall 

 be a steam user or a licensed engineer, and if found competent 

 by the inspector of boilers and elevators, said permit shall be 

 granted. The inspector of boilers and elevators may revoke 

 such permit for cause. 



At all times when boilers are in use and engines run there 

 shall be in charge an engineer having a certificate of license 

 from the board of engineers, such certificate to be displayed 

 in some prominent place where the boilers or engines are in 

 use. 



The engineers, engines, and boilers of the fire department, 

 locomotive boilers used on railroads, and steam boilers sup- 

 plied with water automatically, and having no pumps or injec- 

 tors and used only for heating dwellings, not carrying a steam 

 pressure of more than 8 Ib. per sq. in., are exempt from the pro- 

 visions of this ordinance. 



Every applicant for license who fails to pass the examina- 

 tion of the board is required to wait 4 wk. before again making 

 application for license. Applications for license must be made 

 upon blanks furnished by the inspector of boilers and eleva- 

 tors. The applicant must have had an experience of at least 

 2 yr. at mechanical or steam engineering, and must write and 

 state his experience on said blank. He shall go before the 

 inspector of boilers and elevators and make oath that his 

 statements are true. 



Licensed engineers must give to the inspector of boilers and 

 elevators notice of changes of employment when he accepts 

 or leaves his position, and within 24 hr. thereafter he must 

 give the name of his employer and the location of the boilers 

 in his charge. Licensed engineers must make semiannual 

 reports of the condition of all apparatus under their charge to 

 the inspector of boilers and elevators during the first 10 da. 

 of January and July.
