Over a month ago I contacted one of the folks at UNLV who deals with fire extinguishers. My intent was to bring to their attention that for at least two months many of the boxes labeled for fire extinguishers in the parking structure have been empty. I listened patiently as I was told that they are frequently stolen and it takes a while to replace them. I said that I understood completely but couldn't we cover the signs up so that while we are waiting for them to be replaced some unfortunate person does not run to several boxes while a fire burns and find each empty. The reply was a solid no. You see it's mandated by fire authorities that we have these boxes so we can't cover up the labels.
So it's better that someone burn while looking for a fire extinguisher than know ahead of time where to find one that is actually there.
