Fire extinguisher
From Memory Alpha, the free Star Trek reference
Fire extinguishers or manual extinguishers were hand-held devices containing a substance used to extinguish a fire.
They were typically located in easily accessible areas, such as the bridge and corridors of a starship. (Star Trek VI: The Undiscovered Country)
Bajoran sub-impulse fighters were equipped with fire extinguishers. In 2371, Lieutenant Jadzia Dax attempted to use one to put a fire out in a plasma conduit, but it was empty. The fighter subsequently crashed on the surface of Bajor. (DS9: "The Siege")
In late-2371, during a joint Obsidian Order/Tal Shiar attack on the Founders' homeworld, Lovok's Warbird was severely damaged. During the battle, a section of the bridge set on fire. Two Romulan officers quickly proceeded to put it out using Romulan fire extinguishers. (DS9: "The Die is Cast")
In 2372, the USS Defiant suffered severe damage during Dr. Lenara Kahn's attempt to create an artificial wormhole. The entire engine room was engulfed in a plasma fire. Lieutenant Commander Eddington observed the extinguishers the damage control team were carrying would not be enough to put it out. (DS9: "Rejoined")
In 2375, the USS Rio Grande, carrying Odo and Weyoun 6, was attacked by several Jem'Hadar fighters. During the engagement, the runabout interior caught fire. Weyoun, using a manual extinguiser, put the fire out. (DS9: "Treachery, Faith and the Great River")
Later the same year, during the Second Battle of Chin'toka, Ensign Nog reported that the fire-suppression system aboard the Defiant went down. Worf told him to use a manual extinguisher. (DS9: "The Changing Face of Evil")
