- 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 m³ (13,000 ft³). 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 statification 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. Unwanted reignitions and back-draft explosion can occur. Toxic and hazardous by-products that result from halocarbon fire suppression are likely to be present. Depleted oxygen and combustion gases, such as carbon dioxide and carbon monoxide, will also exist. This report describes recent tests in which post-fire suppression compartment characteristics and their impact on compartment reclamation were investigated.
