I had the fire suppression system go off while I was in the datacenter once. Scariest thing knowing all the oxygen is being pushed out of the room by the heavier gas.
I’ve never moved so quick to the exit as I did then. Took 2 breaths along the way, was extremely light headed for about 5 minutes afterwards.
It went off because HVAC guys were using an angle grinder to cut some ducting only feet away from the intake vent. All the smoke got pulled in and set off the fire alarm.
We have a fire suppression system attached to a big red button for our trucks. One guy pressed it because he wanted to see what would happen. The truck essentially “explodes” covering everything in dust. Dust that really doesn’t like lungs.
Where I used to work we had an FM200 system that I was always super-careful around. If I even thought there was a chance I could set it off I would disconnect the firing pin then leave my car keys there so I couldn't leave without re-connecting it. They company that installed it said the sensors are looking for "fine particulate matter" so even things like drywall dust could set it off.
How many 14th-Gen Cascade Lake PowerEdges have you had the misfortune of working with? Almost as if Dell replaced their entire firmware team with wish.com ChatGPT for that line of servers.
