Random Blue strobe in store

I spotted a Blue Strobe L series LED at my local supermarket, what would this be used for? I’m assuming it’s part of a security system hence a blue strobe.

It can be for a variety of things, like a refrigerant leak (more than likely).

I’ve seen instances of grey integrities with the same coloured strobe lens used for that exact thing. Many at local Krogers.

Could be a CO2 alarm
