In 2009 and 2010, independent research was performed under the name PROMESIS, mainly on the initiative of the French Atomic Energy Commission CEA, in collaboration with a group of scientists, consultants (including TNO), emergency services, industrial partners, supervisory bodies and a team of experienced, well-trained fire fighters. The aim of this research was to obtain an insight into the smoke-cooling performance of various water-based extinguishing systems (including low pressure, high pressure and One Seven), as well as the efficiency of the correct deployment tactics for each system during an indoor attack. For this, 170 tests were performed over two years under constantly reproducible conditions in a specially built test set-up, among other things, fitted with 240 heat sensors and flux meters, even measuring parameters such as the decrease in weight of the fuel, the internal pressure and the opening of the access door.
