they be used as part of a proper fire suppression strategy. Reading what others have written, they all center around sprinkling an area which is correct, so I'll add a few comments on sprinklers in general.<o:p></o:p></span></p>

event, (see attached photo) with temperatures rapidly rising inside of a confined space enclosure with one or two heavy walled aluminum or steel cylinders full of flammable liquid (assumption that the gases are flammable). Should the cylinders get too hot,
combustion can occur.<o:p></o:p></span></p>
