Hot box or other types of exterior fire riser enclosures

[C***@ch2m.com]

Got an Industrial site, mix of flammable processes and non-hazardous processes. Multiple buildings, open sided structures, no walls. Location is in the south. Freezing is possible.

Original scope has typical block buildings for the fire risers. Some buildings have two systems, others may have 3-5 systems.

Space on the layout is tight and of course Fire Protection is the one that they are looking at to reduce footprint. They had three 12x10 buildings in estimate for the various areas.

What was asked about is using a Hot Box or similar smaller heated enclosure to just house the system valves and riser components. No room inside for much more than that. Real tight and compact. To work on systems would require the "box" to be opened for access.

Anyone used anything like this?

My main concern is structural integrity against fire.

This is a FM insured facility so that could play into the decision.

My preference is a building, not a gingerbread house.

Any info or experience or possible vendors of such would be appreciated.

I have used HotBox enclosures on government facilities in the past, but they
only housed the BFP. All of the sprinkler system control valves were
installed inside the building. The enclosures did have easy access, but they
were also pretty small. Installing 3-5 systems into one enclosure could be
an issue.

[Steele, Andrew]

Open sided construction creates an exposure problem to firefighters who might need to access control valves, if/during a fully involved active fire. We had a warehouse fully involved (1987 Sherwin Williams), large areas of roof collapse, where the sprinkler mains needed to be shut down to stop continued dumping of sprinkler water from ruptured overhead mains, to help minimize ground contamination and run-off from the site. Consider if the valve arrangement is such that two firefighter's, in full gear and air-packs, could get into the box and work the valves.

Thanks,
Andrew Steele

Yes that is an issue, there would have to be doors that could be opened to access operable valves.

There are also PIVs on all system run-ins so sprinkler systems can also be shut down that way without interrupting hydrant flow.

We build what we call a "pump in a box" 10'X18' but it could be made smaller to house only risers. They are structurally designed for the conditions at the intended location, all metal siding and roof with a structural steel base. Pre-piped, insulated, heated, lighting, fire alarm conduit and an electrical breaker panel. Routinely we build 1,500 and 2,000 gpm diesel pumps, deliver them on a truck and crane into place. The riser only house could probably be pretty small, maybe 5'X5'. Can't say how serviceable they would be if a valve had to be replaced but I'm sure everything could made accessible enough to operate and test.

I'm very familiar with the prefab pump houses. Have used them many times.

They don't want anything big enough to stand inside. Small, tight and close. You'd have to remove panels to access the valves for service.
