The combustion chamber shall be scraped clean to its original surface how often, and shall be inspected for deterioration or defects?

• A. Daily and inspected for deterioration or defects
• B. Once a week and shall be inspected for deterioration or defects
• C. Monthly and inspected for deterioration or defects
• D. Yearly and inspected for deterioration or defects

Answer: (B)

Regular maintenance of a Type K extinguisher involves keeping the combustion chamber clean and checking for any signs of wear or damage on a set interval. Cleaning the chamber down to its original surface ensures all residues or deposits that could affect heat transfer, seal integrity, or proper operation are removed. At the same time, inspecting for deterioration or defects helps detect cracks, corrosion, worn components, or leakage paths before an emergency occurs. The weekly interval is chosen because it provides a practical cadence to catch developing issues without the excessive effort of daily care or the risk of missing problems with longer gaps. Cleaning and inspecting less often than weekly could allow deposits to build up or subtle damage to go unnoticed, while more frequent cleaning isn’t typically necessary for routine operation.
