Fire extinguisher

A fire extinguisher is a handheld active fire protection device filled with extinguishing agents such as dry chemical powder, co2, water, etc. used to extinguish or control small fires, often in emergencies. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user, or otherwise requires the equipment, personnel, resources or expertise of a fire brigade.

Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an agent that can be discharged to extinguish a fire.
Fire extinguishers manufactured with non-cylindrical pressure vessels also exist, but are less common.
