Abstract
This report summarizes the results of a Project Arrangement entitled “New Fire Suppression Technologies on Board Naval Ships (FiST)” carried out under the Canada/Netherlands/Sweden Memorandum of Understanding on Cooperative Science and Technology. The FiST project had three main areas of focus; 1) fixed fire suppression systems, 2) portable, manually operated fire suppression systems, and 3) firefighting on submarines. For fixed fire suppression systems, large scale fire suppression testing was carried out to determine the effectiveness of low pressure water mist systems under well ventilated conditions, the effectiveness of high pressure water mist systems in a damaged condition, and the effectiveness of using water mist in conjunction with deluge systems for the protection of ammunition storage spaces. For the damaged high pressure system, damage was simulated by reducing the number of operational nozzles, by reducing system pressure and by introducing damaged water delivery pipe segments. The results of large scale fire suppression testing of a dual agent (water mist / Novec™ 1230) system are reported. The use of water mist in conjunction with Novec™ 1230 was found to significantly reduce the levels of acid gas in the test space. The effectiveness of gaseous fire suppression agents, including Novec™ 1230 (a perfluorinated ketone), carbon dioxide and nitrogen, in suppressing or extinguishing electrical cabinet fires was investigated. This study included analysis o
