At Walmart the other day I spotted this fire diamond. It was randomly there on a wall on the side of the store, with seemingly no explanation. There were no chemical tanks or anything near the sign, but there was a door that was a little bit away.


**I cannot find anything that has this fire diamond**, let alone a corrosive oxidizer.


Any help in finding this mystery chemical is appreciated.


The fire diamond is shown below. It does use the informal "COR" symbol, which means corrosive.

I agree with Jon Custer's comment. This symbol (see below) is not for any specific chemical:

The [ComplianceSins.com](https://www.compliancesigns.com/pd/nfpa-704-diamond-sign-with-3-4-2-cor-oxy-hazard-ratings-nfpa-printed-342cor-oxy) says following about this ***NFPA 704 Diamond with 3-4-2-COR\_OXY Hazard Level Indicators***:
