Door Must Remain Unlocked During Business Hours Sign Adhesive 2inches by 24inches Long

The most important feature of any evil laboratory isn't in the laboratory—it's the escape route. Some of whom we'll charitably call your “medical volunteers” aren't all that enthused about what passes for clinical trials out here on your remote island fortress. If enough of them were ever to…to actively discontinue participation, you would need to get out in a hurry. When the klaxxon is wailing, when the force fields are off-cycle, and when the containment “nurses” have been overpowered by hirsute four-armed centaurs with 'roid rage, you're gonna NEED that fire escape door to be free and clear. Keeping important escape routes unlocked and unobstructed isn't just good housekeeping; it's good policy. Help everyone remember the rules with this helpful workplace safety signage from Sutter Signs. Sutter Signs Workplace signage is printed in USA, not on a remote island fortress—but hardly for lack of trying.
