Apparently.. (I say apparently because I really don't have anything to do with it).. Apparently, we have a few people in our group that want to make sure that everyone else in the group is fully aware of various safety rules that exist at the University. So, these individuals who shall remain nameless feel compelled to make sure that other certain individuals, who shall also remain nameless, are aware of said safety rules. Luckily, the University has provided a nice placard, which is probably about 20 inches by 16 inches, which provides the necessary information. So, these groups have taken it upon themselves to position said placards in locations which will be obvious to the other interested parties. For this particular placard placement, it was apparently determined that a single placard hadn't been an effect teaching aid, and multiple placard were necessary. These pictures show the results.
