Which type of fire extinguisher is not capable of undergoing complete maintenance?

• A. Rechargeable fire extinguisher
• B. Non-rechargeable fire extinguisher
• C. Stored-pressure fire extinguisher
• D. Portable fire extinguisher

Answer: (B)

Non-rechargeable fire extinguishers are designed for one-time use and cannot be refilled or reused once they are discharged. After they have been used, they typically need to be discarded and replaced with a new unit. This is in contrast to rechargeable fire extinguishers, which are meant to be refilled and maintained after use, allowing them to be reused multiple times. Stored-pressure and portable fire extinguishers also fall under the category of rechargeables but can vary in terms of maintenance protocols depending on their specific design. Thus, the non-rechargeable extinguisher's inherent design limits its ability to undergo maintenance, making it the correct choice for this question.
