Treated wood identification

I have some wood I keep in a closet.



Most is plain untreated 2x4 pine and plywood.



But one 2x4 is marked as follows:



WeatherShield



Above Ground only



ESR-2240-UC3B



I found the company website, but no info regarding the material on the label.



I want to know if it is safe to keep that one piece in a small closed where the door is kept closed except when retrieving wood.



Thanks.

ESR 2240 tells me this is treated with treated with a copper and azole preservative system. That is CA-B or CA-C

It is safe provided that there is no overhead lighting in the closet.

I see an SDS is available:

Looks like a bit of overkill and main hazard is from sawdust like any other wood.
