These conditions having been complied with, the boiler is thoroughly
tested, and if it is deemed capable of doing the work required of
it, a number by which it shall hereafter be known and designated is
placed upon it in accordance with the city ordinance: Failure to comply
with this provision is punishable by a fine of $25. A certificate of
inspection is then given to the owner, for which a fee of $2 is paid.
This certificate sets forth that on the day named the boiler therein
described was subject to a hydrostatic pressure of a certain number
of pounds to the square inch. The certificate tells where the boiler
was built, its style or character and “now appears to be in good
condition and safe to sustain a working pressure of —— to the square
inch. The safety-valve has been set to said pressure.” A duplicate of
this certificate is posted in full view in the boiler-room. In case
the boiler does not stand the test to which it is subject, it must be
immediately repaired and put in good working order before a certificate
will be issued.
