(a)  boilers are equipped with the following protective devices:

i.  a high-pressure limit control on steam boilers or a high-temperature limit control on hot-water boilers, as the case may be, and such controls shall be independent of any other device controlling the energy source;

ii.  a low-water level limit control independant of any other device controlling the feedwater supply to the steam boiler;

iii.  a high-water level limit control independant of any other device controlling the water-intake of the steam boiler; and
