Fire extinguisher

A fire extinguisher, sometimes known as a flame douser was a tool used to put out fires with the use of some sort of fire-retardant material, such as halon. Astromech droids including the R2 and R5-series were fitted with fire extinguishers as part of their standard equipment loadout.

In 0 BBY, after escaping from the first Death Star, R2-D2 put out a small fire that was started on the Millennium Falcon after it took several hits from pursuing TIE fighters. A few years later, he again made use of his built-in extinguisher while on Cloud City. This time it was used as a smokescreen to blind the stormtroopers that were chasing them.
