how do you install them

[osmedicus]

It's rather complex and requires significant planning, calculations, and placement to ensure that the end product will protect the contents of the hangar. It was a joint venture between the general contractor, engineers, electricians, and the fire sprinkler company. To break it down simply the system is composed of the generators, sensors, pull stations, pressurized tanks, valves, piping, and integration into the existing alarm/controls system.

They must have some kind of giant vacume or something because that was a huge pile of foam!

[osmedicus]

Read my response to the poster below, we let it sit overnight and by the next morning there was nothing left except for something similar to a soap film on the floor. The foam solution expands at a rate of 750:1 (if I recall correctly) so it's easily understood that a majority of the foam mass is simply entrapped air. Once the surface tension of the foam bubbles yields to atmospheric pressure you are left with a completely eco-friendly residue that can be released into the storm water system.

That's an application I've never seen. Pretty crazy. Who intalls these systems? Sprinklerfitters? I've installed a foams system...which is really a regular wet system with foam discharge tank that releases into the system when tripped

[osmedicus]

The overall system was installed by a combined force of the general contractor and sub-contractors. The HEF system was installed by a fire suppression contractor who, as you know, are sprinkler/pipe fitters. This was similar to your job in that there are pressurized foam solution tanks that when tripped route through mixing valves and into the dry system.

why is there two differents alarms and strobes ?

[EliasPadillaTV]

I have a question. How or what does the foam include? Is it Toxic?

[alarm741]

How do you get rid of it? I mean its a large foam covered area so do you spray it?

[paul9511]

Good luck to clean it all

[Itsnattatooma]

creep drop

[RaveSnoreThrong]

So if this stuff is eco friendly, does that make it non-toxic for humans?

[Xcokedav096]

that is a lot of semen

[firealarm211]

the foam seen here works to put out the fire. its kinda like the water that fire men use, but it puts out the fire faster, and also check out tjs468's channel, hes only 8 like you.
