I’ve done a lot of work near/for/at chemical companies. They all have the regular slow-woop siren telling you to leave, preferably into the wind. And that’s not a fun thing to hear, because they really don’t like to push that button for any old thing.

But there’s also the far worse “shelter in place” siren. When you hear it, it means shit is so fucked you can’t even run away. And most places aren’t exactly suited for riding out a chemical disaster.

The Danish Air raid sirenes allways gives me the creeps, I think it’s the clear sound that gets me. Unlike other sirenes that has a harsha tone, the Danish ones have a almost sterile tone, convaying the feeling of “this sound is vary important, stop now and go Inside. Like a scary Teacher”

Starts at 0:15 and later has a “all clear” tone later on on youtubes

Then again it might just be because I had to listen to it as a kid, and I was a weird ass kid

Nothing followed by the sound of a lot of cars leaving the Facility very fast.
