We have so many fire alarm tests and then drills that everyone where I work now ignores the alarm. No kidding.
When I first got there, I jumped out of my skin (I don't like fire and the possibility of being burned alive) and headed for the door. When noone moved, I looked like a fool. I soon learned that the noise and flashing lights don't mean anything. How pathetic is that?
Remember kids, the fire alarm does not necessarily mean FIRE, but it should always mean EVACUATE. Chemical spills, hazardous environments, crazy people with weapons are all reasons to pull the alarm. DO NOT WAIT to smell smoke or see flames.
How bad has our society declined? Bad enough that we have "Crazy people with weapons" cotingency plans.
