Paul Grimwood introduced Rosander and Giselsson's firefighting tactics using pulsing water-fog and 'gas cooling' methods of fire control to the UK in 1984, with several trips to Sweden, including Stockholm FD, to train in the innovative techniques. These methods of fire control were trialled at three fire stations in the capital between 1984-1994 before a national roll-out across the UK from 1998.
In 1999 Paul first introduced the 3D Firefighting concepts in his firefighting manual Flashover and Nozzle Techniques (published in seven languages) bringing '3D Firefighting' to firefighters across the globe.
In 2003 and 2007 the 3D Firefighting methods were further described in two additional books published with Paul and his co-authors, Koen Desmet, Ed Hartin, John McDonough and Shan Raffel, describing in some detail the Swedish firefighting tactics that changed the face of European compartment firefighting from the 1980s onwards.
