1 day after people: Power fails, and it is encased in it's glass case in the dark.
1 month after people: Some SCP's and animals are in the office, and now it is not safe.
1 year after people: A wild raccoon breaks the case, and SCP-000-J is unprotected.
10 years after people: The entire magazine is torn and is rotting away.
