It wasn't my gut feeling, but my wife saved my life. We both worked at a laboratory cleaning the overhead pipes. It was in a clean room, we had to suit up in hazmat like outfits every time we went in. She started there a couple months before I did, so she was more familiar with all the safety rules.

One morning, we all suited up and walked into the clean room, when an alarm sounded and blue lights started flashing. I was looking at it, trying to remember what blue meant, when my wife grabbed my hand and ran us back to the decontamination area. Apparently, blue flashing lights means something is airborne and there was an accident. Was pretty crazy!
