How to securely have a an 'office' vault and have only that vault accessible at the office?

I have a lot of passwords that I use for Work. All those passwords reside in 1Password, but as I don't have 1Password installed on my office computer (because of the hereafter mentioned reason), I don't have access to those passwords. They now reside in a 'Password.txt' file. Not joking, but those passwords aren't important.

I want to delete that file and use 1Password at the office as well, but there doesn't seem to be a secure way to have your 1Password account enabled on an 'external' (read: office) PC, whilst having your personal vault away, hidden and unavailable.

By Twitter, 1Password advised me to go to "Settings -> Vaults, and uncheck the to be hidden vaults". However, this only hides them from the 'all' section. If I click on myself in the application, top left corner, the box expands and all other vaults are shown again, creating access to my personal passwords.

It would be nice to 'delete' all vaults, except the Office vault. At this point, an 'Office' vault feels redundant and a written note (either file or paper) seems the only way to have Office passwords available and personal ones unavailable..

(Office PC is Windows, noted below, but primarily use a Mac)
