If the top marking on the solid state oxygen generator is missing, what is the correct action before use?

• A. Remove cover and verify white marking; do not use if black or brown
• B. Use without check
• C. Keep top on and proceed
• D. Return to stock

Answer: (A)

Inspecting safety markings on oxygen-generating equipment is about confirming that the device has been checked and is safe to use before it’s put into service. If the top marking is missing, you should remove the cover to view the marking underneath. A white marking means the unit has passed the required verification and is considered safe to use; if you see a black or brown marking, it signals a fault or out-of-spec condition, and the device must not be used. This prevents deploying an unverified or potentially unsafe generator. Skipping the check, or proceeding with the top in place, could hide a critical safety issue, and returning to stock without performing the check doesn’t address the missing labeling.
