In which type of fire extinguisher are the extinguishing material and expellant gas kept in a single container?

• A. Cartridge operated extinguisher
• B. Wheeled fire extinguisher
• C. Stored-pressure fire extinguisher
• D. Water type fire extinguisher

Answer: (C)

The choice of a stored-pressure fire extinguisher is correct because this type of extinguisher contains the extinguishing agent and the propellant gas within the same pressurized container. This design allows for immediate release of the extinguishing material when the valve is opened, making it quick and efficient in putting out fires. In a stored-pressure fire extinguisher, the cylinder is filled with the extinguishing agent, such as water, foam, or a dry chemical, and a separate pressurized gas, usually air or nitrogen, is used to propel the agent out of the nozzle when activated. This seamless integration of the propellant and extinguishing agent allows for a more compact design and ease of use in emergencies. This differs from cartridge-operated extinguishers, where the propellant gas is contained in a separate cartridge. Wheeled fire extinguishers are typically larger, designed for larger fires or industrial settings, and may have different configurations that do not meet the criteria given in the question. Water-type fire extinguishers usually refer specifically to those that contain water and may not always align directly with the definition specified in this query about containment within a single container.
