3.3 Fire
Sensors detect fire by temperature and air ionization and a forcefield contains it by cutting off oxygen, while handheld extinguishers and venting ship sections to space are also available.
In case of fire on board Voyager, sensors immediately detect the change in temperature and air ionization. A forcefield is activated, containing the fire, sealing it off from further oxygen supply. This extinguishes most fires very quickly and with a minimum of damage. Handheld and other extinguishers can also be made available. As a last-ditch effort in the case of a major disaster, one or more sections of the ship can be vented into the vacuum of space, cutting off the fire's oxygen supply. This will probably be hazardous to the health of any crewmembers unlucky enough to be in the area.
