It is a quite unusual observation.
1. OCIMF VIQ does not contain any reference or guidelines regarding storage of Argon. Which paragraph was stated as a basis of the observation?
2. Argon is an inert gas. There are only 2 known chemical compounds of argon. They only exist under extremely low temperatures. In no way Argon capable to react with Oxygen (i.e. burn) under temperatures above 100K. There is no fire hazard when storing this 2 types of bottles.
3. Probably, the main concern of SIRE inspector was a possible confusion of the crew which may intend to use Oxygene instead of Argon (by mistake) if bottles stored next to each other. From this point of view, it is not advised to mix Argon bottles with others. Please provide the quote of the observation for a more detailed reply.

5.35 Are spare oxygen and acetylene cylinders stored apart in a dedicated storage and is the storage in a clearly marked, well-ventilated position outside the accommodation and engine room?

The observation is unreasonable and has no legitimate basis. Master and CE should negotiate such situations with the inspector to clear it.
