Yesterday’s team-building session turned out to be a bit more exciting than I had anticipated. We were just getting started when a firefighter knocked on the door of the meeting room and said, “We need to evacuate the building now.” As he disappeared down the hall to knock on the next door, we heard him muttering something about “not a drill.” Was it a fire? Poisonous fumes? Anthrax?
I should explain that, due to a shortage of suitable conference rooms, we have been having these sessions, not in our own building, but in another building in the hospital complex, where a lot of research labs etc. are located. Each part of the building is isolated behind doors that require a key card to pass through, in either direction. (Why? I can understand restricting unauthorized people from coming in, but why stop them from going out?)
Anyhow, we dutifully made our way to the nearest exit stair and walked down, under the impression that you should not take the elevator during an emergency – although there had not been any alarm, just this guy going door to door. Well, you guessed it. At the bottom of the stairs was a door, labelled “This door unlocked by fire alarm” – locked. We had to wait there until someone who worked in the building came with a card and let us out.
We didn’t have to wait long – no more than a minute or two – but that seems like a long time when you are stuck with a locked door ahead and an unknown hazard behind. Besides, I have a particular horror of getting locked in a stairwell. I know some people who are phobic about elevators, but to my mind stairs are much scarier. When you get on an elevator, unless it malfunctions, you can be pretty sure that it will let you out. And if it does malfunction, there is an alarm button to call for help. Whereas with stairs, you enter the stairwell and the door locks behind you – no going back the way you came in. You just have to take it on faith that you will be able to get out at the other end. No alarm button, either. That’s what I call spooky, even if you aren’t trying to evacuate.
Well, we got out eventually. We milled about outside for a little while then returned to our own office and went back to work. So much for team-building for that day.
Later in the afternoon the director of research sent an email explaining that the alarm was caused by “a substance.” The newspaper was less cagey, and identified the substance as
picric acid.
Picric acid is some very bad stuff. It is related to TNT, but more explosive. It was used for munitions during World War I, but it is now considered too dangerous to use for weapons (!) – too likely to go off when you don’t mean it to. It is the stuff that blew up in the famous
Halifax explosion in 1917. (Those of you who were with us on the trip to Halifax in 1999 may remember being dragged to a museum exhibit about that event.) Apparently picric acid is fairly harmless as long as it is kept in water, but in this case it had been allowed to dry out and crystallize, in which state it is liable to detonate from heat, friction, sudden movements, or just plain cussedness.
The paper didn’t say how much of the stuff there was. Clearly not a shipload, which was enough to level a good portion of Halifax. Was there enough to blow up a building? A room? The container it was in? Enough, anyway, that they evacuated a three-building complex and called in the bomb squad.
All’s well that ends well, but I’m still a little freaked out. Who knows what horrors lurk behind the chaste walls of the research tower?
