Originally posted by Speedy Parker No not even in high rises. Don't argue with me I used to inspect fire safety systems. The only electric used in some systems is a 12 volt signal similar to land line telephone. Those systems have electric detectors and electric solenoids are used to open a valve to allow water to flow into the sprinkler piping network.
The 12 volt DC required for that is supplied by the same diesel generators used to supply powered for pumps that are required for proper pressure to upper floors in extremely tall buildings.
But the majority of sprinkler systems are just a simple glass ampul which breaks and releases water when heated.
You are a know nothing dumbass.
ignoring all the grandmatical [sic] mistakes, your actually saying these sprinkler systems use electricities.
yes ? -

Originally posted by Meikai man, structural failures happen all over the world. nothing too weird about that. but uhh… guys, if they aren't on shore within like 10 minutes of falling without a PFD into waters that [seemingly] calm, they either got pinned to the riverbed by debris and drowned or didn't know how to swim and drowned. corpse recovery is what's being impeded by the lack of electricity, not "rescue".
I think it was in 1986 that the 50th Anniversary of the Golden Gate Bridge occurred and something like a million people got to walk onto the bridge when it was closed for the day to celebrate. the fucking bridge had flattened out its design road arch.
I think they did the same thing for the 75th anniversary too but I wouldn't suggest doing it on it's 100th.
also, some people were jumping up and down. whats that scientific term called where soldiers have to stop marching because the vibrations can collapse the bridge?
this bridge had to many people on it all at once. they should have had a limit to how many crossed. probably nothing wrong with the design just over its expected capacity -
