What type of extinguisher has the propellant stored inside the cylinder?

• A. Stored pressure portable
• B. Cartridge operated
• C. Water mist
• D. Dry chemical

Answer: (A)

A stored pressure portable extinguisher has the propellant stored inside the cylinder itself. This design means that both the extinguishing agent and the propellant are contained in the same cylinder, allowing for immediate deployment of the agent upon activation. When the extinguisher is triggered, the pressure within the cylinder forces the extinguishing agent out through the nozzle, effectively discharging it onto the fire. This design contrasts with cartridge-operated extinguishers, where the propellant is in a separate cartridge that is not stored with the extinguishing agent. In that case, the user must puncture or otherwise activate the cartridge to release the propellant before the agent can be discharged. Water mist extinguishers typically use distilled water and are designed to cool the fire and displace oxygen, but the propellant is not stored directly with the agent as in a stored pressure system. Dry chemical extinguishers can be either stored pressure or cartridge-operated, but if they are stored pressure types, they will have the propellant within the cylinder as well, enhancing their readiness and rapid deployment. In summary, the key feature of a stored pressure portable extinguisher is the integration of the propellant within the cylinder, allowing for a more straightforward and efficient operation in emergency situations.
