Effects of a Water Spray Cooling System During Real Scale Halon 1301 ReplacementTesting on Post Fire Suppression Compartment Reclamation

摘要

Real scale tests were conducted aboard me ex-USS SHADWELL with HFP with limitedbaseline comparison tests with Halon 1301. Two of the objectives of the full scale machinery space testing were to determine the optimum post fire suppression hold time (time prior to venting) and to evaluate the option of using a water spray cooling system (WSCS) to reduce compartment temperature and acid decomposition products and therefore expedite compartment reclamation. Results show that the WSCS system employed is a viable option for rapid reduction of compartment temperature. The low water pressure WSCS tested provided very rapid compartment temperature reduction in 15 seconds with less than 20 gallons of water.
