Found these in my files - not sure if I sent these in before or not.
Sorry for the quality - it's from my phone.
Here's 2 from a local hospital...
It's by the ambulance entrance we (FD) use on a daily basis. Happened to look over and see this one day.
It's just a length of regular NM... don't think it's supposed to be "surface mounted"
The signs at the other 2 entrances are all RMC or LQTFMC to LB's.. the way they're supposed to be.
