Hillman English White Danger Sign 10 in. H X 14 in. W

Using this Caution Hazardous Area Authorized Personnel Only Sign, warn pedestrians and workers to remain vigilant as they traverse through or near a potentially dangerous area. Chances are high your location won't be as threatening as Gotham City or Mordor, but probably best to display proper signage anyway. Wouldn't want another Joker origin story.
