Real Scale Halon Replacement Testing Aboard the Ex-USS SHADWELL: Phase II - Post Fire Suppression Compartment Characterization.

Abstract : This report describes real scale Halon 1301 replacement tests conducted aboard the ex-USS SHADWELL. These tests were conducted in a simulated shipboard machinery space. The floodable volume of the space was 370 cu M (13,000 cu ft.). Most tests were conducted with heptafluoropropane with limited baseline comparison tests conducted with Halon 1301. Parameters such as fire extinguishment, oxygen depletion, agent concentration inhomogeneities, thermal stratification and hydrogen fluoride production were examined. Compartment reentry after a fire incident on a U.S. Navy ship may be the most critical part of the firefighting event and potentially the most dangerous.
