The “CARGO FIRE NET” looks much like a conventional net, the difference is that it was invented to extinguish fires in cargo settings. What makes this net different is the fact that it has several “suppression lines” inside, and throughout it, with (8) evenly spaced, exposed brass “#6540 suppression jet heads” connected to those lines, so as to spray “non-corrosive fire suppression agent” in the occurrence of fire. The “non-corrosive fire suppression agent” will be delivered by way of a centrifugal pump pulling from a 30 gal. holding tank, and into the net, so as to be sprayed. It can be used conventionally as a net, by draping it over the cargo, or non-conventional by suspending in a fixed state above the cargo. It's a net that extinguishes fires, just put it on the cargo, or hang it above the cargo, and connect it to “feed suppression line”, and walk away. When the “sensors” in the net detect an unacceptable temperature level, they will activate the system, thus starting the extinguishing process. All of this occurs with no attendant being involved, and ending the fear of “blind fires” during transport of cargo. Yes, the “CARGO FIRE NET” is the answer, a protector of Life, Property, and Merchandise. It's ready for industry, and industry is ready for it, “It's a better way”.
