and they want to put sprinklers in every new home built and many areas
there going to have to use antifreeze and this is what happens when
not mixed properly.
some times i think we are going backwards not forward with technology.

I didn't know that antifreeze could ignite!

What the hell are they doing for crisake!

I can just imagine how that design was arrived at:

Ok now guys, we have to put something in the sprinkler system that
will stop the lines from freezing. What should we use?

We can use antifreeze, of course, and it's cheap too.

Does anyone know if antifreeze is flamable?

Nobody knows?

No. not for sure. But I think I remember hearing that if you mix it
just right with water, it wont ignite.

OK, sounds good to me. That's what we'll use.

But we'll have to put a disclaimer on the container that warns them
that it's dangerous to mix in too much and that we're not liable if
they do. Make sure it's written in Spanish too.

several things had to conspire to make this happen .but why you would
use a substance you know is flammable in the first place  is beyond
imagination.  you mix it and them it sits there and degrades over time
in pipes and you never know what the result could be.
I just cant wait to see what the idiots on the code panels are gong to
come up  with this time for an excuse.
some code panel members need to have there professional licenses
removed and jailed. for even thinking about some of this stuff like
putting sprinkler heads in elevator shafts and then designing the code
that someone could be trapped in a car and die.

got one better,  had an AHJ (ie.. state inspector)  require us to remove all
smoke/fire detection equipment from elevator shaft after a single sprinkler
head was installed at the top of a 3 story shaft...

Businesses which have large frozen food areas have air filled fire sprinkler
systems. A head pops, this releases the air pressure, then that activates a
water valve. Water then flows through the pipes.

And they of course don't want the alarm guy to test the flow switches on
these! Then they would need to drain the pipes to get air back in...

we do test those in here..And let me tell you that we have a LOT of them...
its so damn cold here sometimes..

The only problem with air filled sprinkler, is that you need an air
compressor for them to work properly, and that can be cost prohibitive..

And now that we have sprinkler that use plastic tubing in residential
building ... under air pressure I am not shure it would last long...

Dry systems have an inspector's test valve on the riser that flows water
past the pressure switch (just as a dump would do) without flooding the
system.  I did it all the time.

Dry systems have there problems as well  drip drums can freeze and
pumps die etc etc.
I have several dry systems I watch and there a pain.

There is an hybrid system where there is a pipe full of air under pressur
that have heads like regular sprinkler head, but its not connected to any
wather supply.

when one head is poped cause of over heat, a valve is release on an other
pipe network that has open head and all over the place and water is pourred
every where...

we call that a deluge systeme here, and you dont want to trig those by error
;-)

We have those in the States, too, but they're not all that
common. One warehouse where I worked on the alarm had
a deluge system in it. I don't know what they originally had
there but my customer was a branch warehouse for a
national chain selling computers and office supplies.

You can only imagine the damages if someone triggered
that.  :^)

seen one in operation once, was working on fire  system and asked the
sprinkler company to come test it so that would have all my signal tested..

he didnt closed the main water valve, he only closed one leg of the
system... it was so fun to see the rainbow inside the warehouse when we were
outside looking in..(the sun was comming in by the garage door wide open ;-)

Geeze - you would think that his insurance company would have required
him to have that system changed.  Probably could have been done just by
changing out the heads and main valve.  Wouldn't have been cheap but a
real money saver in the event of a small localized fire somewhere in the
warehouse.

To warrant a deluge system around here it usually means some sort of
flammable chemical storage or the like.  Something you really don't want
to take any chances with.

Though to watch TV & movies, ALL systems are deluge systems...

Re: Sprinkler system filled with antifreeze cause house to explode when activated


I asked about it.  No one seemed to understand.  We monitored then for several
years until someone else offered to do it for a dollar less or something like
that.  Oh, well.
