Which statement about replacing extinguishers is true?

• A. You must use a similar rating; other ratings are not acceptable
• B. You can always replace with a higher rating
• C. You can replace with any rating as long as it fits
• D. There are no rating requirements

Answer: (A)

Matching the replacement extinguisher to the same rating as the original keeps the level of protection aligned with the specific fire risks present. The rating tells you what kinds of fires the extinguisher is designed to handle and roughly how much fire it can suppress. If you swap in something with a different rating, you could either fail to cover the hazards adequately or misrepresent the extinguisher’s capability in that space. Keeping a similar rating ensures the device remains suitable for the same fire classes and fire sizes, and it helps meet code requirements and maintenance expectations.
