The Slow Mo Guys


Gav and Dan like learning and like fast things. In this episode, they learn about a fast thing.
A fire sprinkler that you can probably see above your head if you are watching this from your office when you should be working. Shame on you! Nah, just kidding. Watch more Slow Mo Guys at work!

TIL: Me, working at an AEC firm (admittedly having nothing to do with Fire Protection other than collisions, as that's a separate discipline), had no idea sprinkler's glass bulbs were color coded. What they don't cover in the video, though, is that the water pressure for these systems is much higher than what you get with a garden hose. So actual operation is much closer to the initial burst we see until they're either shut off manually at the main valve (typical use case) or have run through their reservoir (if there is one, which depending on the building/facility, hazard level, at whatnot you'll likely rarely want it to stop on its own). Also, in order to limit the air in the system, since it's dry installed, they limit the water pressure by not fully opening the main valve until a little water comes out of the end of each branch of the system. After all, you don't want to have to wait for the water once they bulb bursts.

I worked in a warehouse where someone hit a sprinkler head with his fork-lift. The first 983,645 gallons shot out in about 3 seconds and all of it was muddy brown with rusty water. The fire department had to come to turn it off, and the driver was sent out for a drug test XD

The pressure in a real sprinkler system is of course much higher.

I’ve heard that the water in the pipes waiting to do its job can be quite old and icky by the time it’s flushed out creating a smelly and overall unpleasant rescue experience if the water sprinklers are triggered. Rescued by foul water... yum!

PENDENTS 155F• When a sprinkler head has a glass bulb, that bulb typically contains a glycerin-based liquid. Once the air around the sprinkler reaches a certain temperature - often 155F or 200F (68C or 93C) - the liquid expands which causes the glass to break. The water held back by the bulb then escapes and flows toward the deflector, which disperses it throughout the room.

Dealt with sprinkler systems many of times. There’s several versions but the vial is plugging the hole where the water comes out. The whole sprinkler system has to be charged with water pressure. If the pressure drops too low it triggers a alarm
