The Submarine Ventilation Doctrine Test Program was developed to address submarine-specific issues regarding the use of ventilation systems to control smoke and heat movement, maintain habitability in critical spaces or provide safe ingresslegress routes. This program sponsored six test series between January 1995 and August 1996 and made specific recommendations for the use of ventilation during submarine firefighting. Subsequently, questions were raised regarding whether this doctrine might cause the fire to grow beyond the size that would have been obtained in the absence of external ventilation or might inhibit damage control effects by increasing the smoke and heat load. In this report, data from all six tests were pooled and subjected to a meta-analysis. It was found that opening external hatches caused atmospheric conditions in the Control Room to deteriorate while improving conditions in the Laundry Room (fire compartment). Opening of the sail hatches tended to mitigate the effects of opening the Forward Escape Trunk; opening the Weapons Loading hatch had minimal additional effect. 收起
