Conveyor equipment in storage occupancies

[Steve Leyton]

So ... I get hired to write a tech report on an S-1 occupancy and it's
pretty straightforward since the existing (brand new and never occupied)
building is furnished throughout with ESFR. There are no complications
and I get the report approved and ... the client just contacted me in a
panic asking for a new report or an addendum to the previous one that
addresses their conveyor equipment. That they somehow NEVER mentioned
or showed on any of the plans that I was given for reference. I have
a nagging suspicion that they may have been trying to sneak it into the
building but ... it's also possible that I'm getting paranoid in my
mid-life crisis.



Anyway, besides the obvious regarding obstructions as they pertain to
ESFR, can anyone tell me if there are any trap doors in this application
that I might want to know about before taking a meeting with the client
and the fire official? I came away from a brief telecon with the
vendor for the equipment a bit concerned, as he couldn't offer me
anything of substance regarding connection points for sprinkler piping
under the widest belts and platforms (he's checking and will get back to
me). In all these years I've never fire protected a system like this;
have done rollers, push-backs, luggage handling systems at two major
airports, dry cleaning handling systems, rotating retail clothing
fixtures, etc., etc. but not a storage conveyor. Just want to be sure
there's no ticking IED's that I haven't accounted for ...



Happy New Year everybody!

Steve,

Not sure of your storage arrangement or how the conveyors fit in with it. I just finished a single stream recycling facility with 100+ sprinklers under conveyors in a 28000 sqft building. I ended up following standard obstruction rules and it worked out reasonably well. It was pretty much impossible to show on a plan, so I did my best on that and worked with the contractor on where and how once the structure was up.

I have seen these handled a couple of ways:

1 - if the conveyors are low to the ground (2-4' aff), I have seen them allowed to be excluded as long as there are barriers (or lines on the floor) to prevent storage or accumulation of combustible underneath. That would be like the final roll-out conveyor for a pick-n-pack setup where the boxes are rolling towards a palletizing/truck loading area and the conveyor is not within racking - the ESFR system is basically giving OH level protection.

2 - The most common arrangement I have seen is to route a line of standard spray heads under the conveyor calc'd for oh2 with the thought that any pile of combustibles that found its way under the conveyor would be less than 12' tall.

3 - sometimes if the conveyors are high up or if they cross the storage areas they get a line of ESFR's under them since there could be a high hazard fire under them.

When the pipe is under the conveyors it is usually hung from the framing - either along the sides or down the middle - wherever is easier for routing. (I also don't have to worry about seismic concerns so I am not sure how the bracing might play into that)

The challenge comes when there is a metal grate walkway with it (or worse yet just a walkway). You’re suppose to use an intermediate sprinkler beneath metal grating and use the same sprinkler type as the ceiling beneath obstructions. Still looking for an ESFR intermediate.

I'd add that there are several 'trap doors' Steve. What is being conveyed?
Do the conveyors need to be interlocked on sprinkler activation?
How wide are they?
Are there multiple levels/layers?
What is going on below the conveyors (process, fuel load, nothing, and so on)?
More...

I think this one needs a lot of banter (defining the problem six different
ways, ideas, sketches, why certain ideas won't work, why could work, blah,
blah, blah.) Lot's of fortified coffee. Oh–––and client dollars.

I'm prepared to pitch that ESFR isn't required at the ceiling because there's not any storage below the equipment, just handling and debris. So it's a convenience only to leave the ESFR at the roof ...

Belts occur at different elevations and complements of single-level, two- and three- levels high. Assuming protection below because existing ESFR will be obstructed and AHJ is notoriously strict. No rated walls, don't know yet about composition of belts.

Anyway, besides the obvious regarding obstructions as they pertain to ESFR, can anyone tell me if there are any trap doors in this application that I might want to know about before taking a meeting with the client
and the fire official? I came away from a brief telecon with the
vendor for the equipment a bit concerned, as he couldn't offer me anything of substance regarding connection points for sprinkler piping under the widest belts and platforms (he's checking and will get back to
me). In all these years I've never fire protected a system like this;
have done rollers, push-backs, luggage handling systems at two major airports, dry cleaning handling systems, rotating retail clothing
fixtures, etc., etc. but not a storage conveyor. Just want to be sure
there's no ticking IED's that I haven't accounted for ...



Happy New Year everybody!

Steve,
You may want to check out FM Global Data Sheet 7-11. It contains a very
comprehensive overview of conveyors and required protection.

Belts occur at different elevations and complements of single-level, two-
and three- levels high. Assuming protection below because existing ESFR
will be obstructed and AHJ is notoriously strict. No rated walls, don't
know yet about composition of belts.

Subject: RE: Conveyor equipment in storage occupancies
Is the belting FM approved non-combustible? What is the width?
Does the conveyor pass through any rated walls or separated occupancies?
What is driving you to think you have to provide sprinklers below?
Where is the conveyor installed, just above floor level, overhead, etc?

So ... I get hired to write a tech report on an S-1 occupancy and it's
pretty straightforward since the existing (brand new and never occupied)
building is furnished throughout with ESFR. There are no complications
and I get the report approved and ... the client just contacted me in a
panic asking for a new report or an addendum to the previous one that
addresses their conveyor equipment. That they somehow NEVER mentioned
or showed on any of the plans that I was given for reference. I have
a nagging suspicion that they may have been trying to sneak it into the
building but ... it's also possible that I'm getting paranoid in my
mid-life crisis.
Anyway, besides the obvious regarding obstructions as they pertain to
