the.com/fire extinguisher

A red bottle that bets the room on PASS before PASS becomes panic.

means A portable canister of pressurized agent (usually foam, powder, water, or CO2) built to smother a small fire before it becomes a big one.

from The compound is plainly descriptive — 'extinguish' comes from Latin exstinguere, 'to put out, quench,' built from ex- ('out') plus stinguere ('to quench, extinguish'). The handheld device itself is a 19th-century invention, with early patents for portable fire-fighting canisters appearing in the early-to-mid 1800s as cities grew denser and the need for a first line of defense against household and workplace fires became urgent. The name simply describes the job: a tool whose entire purpose is to end a fire before it ends something else.
