Water for Manual Fire Suppression

Water demand for manual fire suppression is analyzed. The Fire Point Theory is validated concerning fuel surface cooling effects and the critical water flow rate is determined and compared with previous investigations. It is shown that the critical flow rate is not the best use of resources. Therefore, the water flow giving the minimum total volume is determined. Data from real fires was compared with this experimentally-determined flow. There is a difference between experiments and real fires in terms of the water flow rate used, the control time and the total volume of water used. The reasons behind these differences are explained.
