16.0 EMERGENCY OPERATIONS16.2 FIRE SUPPRESSION16.1 INTRODUCTION TO EMERGENCY OPERATIONS 10.2 FIRE SUPPRESSIONThe entire philosophy behind the integrated systemsdesign of the Galaxy class starship is one of maximizing crewsafety during all mission profiles and in all emergency situations.Starileet has a long tradition of placing the safety of itspeople first. The extraordinary lengths to which Starfleet hasgone in insuring crew safety in the design and operation of itsships is a persuasive demonstration of Starfleet's commitmentto this tradition and philosophy.The principle of automatic computer monitoring of shipoperations to detect and correct system anomalies longbefore they become problems has long been a means ofoptimizing both crew safety and operational effectiveness.This process alone deals with over 87% of all potentialproblems with minimal crew intervention.The Galaxy class starship, like its predecessors, incorporatesa sophisticated array of redundant systems and backups,intended to assure continuous service of all key systems.Critical environmental support and engineering systems willgenerally employ at least one backup, which is physicallyseparated from the primary and has power supplied by anindependent source.Supplementing these approaches are systems, protocols,trained personnel, and specialized hardware intended tocope with a wide range of potential emergency situations.The habitable volume of the Galaxy class starship isconstructed of materials conforming to SFRA-standard528.1 (b) for inflammability in nitrogen-oxygen atmospheres.All shipboard equipment, furnishings, and personal effectsonboard must conform to SFRA 528.5(c-f). The Chief Engineeris responsible for the observance of these policies by alldepartments and personnel.Fire detection sensors are incorporated into the environmentalmonitoring sensors located throughout the habitablevolume of the spacecraft. These sensors scan for changes inair temperature or ionization, and are also programmed todetect airborne particles or gases characteristic of combustionbyproducts. Crew members can also signal the presenceof a fire by use of personal communicator or comm panel.In the event of fire, monitoring sensors would immediatelynotify Ops as well as Security. In the case of a relativelysmall fire, acontainmentforcefield would begenerated aroundthe burning area by the ship's computer. This field seals thefire off from the atmospheric oxygen supply, causing mostfires to be rapidly extinguished. In the event of such anoccurrence, crew personnel should remain at least two metersfrom the fire to avoid unnecessary exposure to either firehazards or the forcefield.Ceiling mounted detectorcluster projects firesuppression forcefieldForcefield containsflame, preventingatmospheric oxygenfrom feeding fire16.2.1 Use of forcefields for fire suppressionCarbon dioxideexhaust istrapped inside,suffocating fire
