The idea for this technology had existed for a long time. At the end of the 19th century, the American company F.E. Myers produced a system that sprayed water droplets and allowed firefighters to carry them on their backs when fighting small forest fires. A little later, Grinnell also developed a nozzle that fought fires with droplets. But it was not until 1978 that a textbook entitled "Fundamentals of Fire" was published.
Water in droplets - smaller than ground cereal grains
Krister Giselsson and Mats Rosander write in it that in the future there will be a liquid - water, for example - which, atomised into droplets smaller than ground cereal grains, will be the most important fire-fighting agent in buildings. And it was these two men who presented the results of their research after the fire at Scandinavian Star.
In addition, the Montreal Protocol was passed in the late 1980s. The topic was the abolition of substances that lead to the depletion of the ozone layer. Among other things, it was decided to phase out the use of halon as a fire-fighting agent. This gap was to be filled by water mist.
