- Abstract
- A demonstration was given to show the state of development of the gelled CO2/PKP extinguisher for submarines. Four carbon dioxide extinguisher cylinders containing gelled CO2/PKP extinguishant were used on heptane panfires. Three of these were 5-pound extinguishers and one was 2-1/2 pounds. They were compared to a 5-pound CO2 extinguisher and a 2-pound commercial PKP extinguisher. All extinguisher tests were conducted on 9-square-foot panfires. The outstanding firekill capability of the gelkled CO2/PKP extinguishant was demonstrated by extinguishing the 9-square-foot panfire in as little as 2.2 seconds and with only 0.20 pound of PKP. We observed that the gelled CO2/PKP minimizes cloud formation, greatly incrasing area visibility during expulsion.
