Interesting timing. The latest FPC magazine came in the mail today. It
has an article on a grow facility. They used the basis of a tobacco
facility to arrive at OH2. This was for a facility in CO.

It sounds like a reasonable request, but not on your nickel.
The CO2 enrichment may have no impact unless the grow design involves
some sort of CO2 containment tent that interferes with the sprinkler
discharge.
The flammable liquids/gases is about the solvents or say, propane,
that is used to extract the THC. That is not a “grow” operation but
may likely be a process they do on site. One might do some checking to
see if OH2 is OK but it is probably not.
Perhaps the "hazardous waste” mention is in regard to someone
questioning whether or not there would be a quantity of THC
laden sprinkler water that needs to be contained instead of allowed to
discharge to the environment. Maybe the leaf removal process that
happens in the last grow step to encourage bud growth generates
enough “waste” stored on site to be of concern.
By the way, there is a very good chance the ceiling temperature above
the grow lighting is much hotter than you might expect. Furthermore,
if the ventilation system fails for some reason and the lighting is
not automatically turned off, then all bets are off. You might also
take note if the lighting design tries to congregate the lighting
ballasts at some unexpected location that creates an odd situation.

That note comes from the plan reviewer. My firm was hired to design
to OH2. But it got rejected by the AHJ and had that note on the
rejection. My scope was well defined and this is way out of the
scope. So I was just wondering what others have encountered in these
facilities.

Where does that note come from?The AHJ or owner or Engineer of Record?
Either way that info should be provided by the Engineer of Record to
the installing contractor to be included in submittals to the AHJ.I
would certainly hope an Engineer is not dumping this off on the
installing contractor.

This is obviously outside of our scope and I am punting this back up
the chain. But, has anyone that is sprinklering these MJ facilties
run into this:
"Provide a letter from a state licensed PE or Consulting Firm
approved by the City of XXXXXXX, that supports the fire sprinkler
design assumptions. The letter shall be signed (wet) and address
the design assumptions that includes the use of CO2 enrichment,
flammable liquids/gasses, and hazardous waste and the impact that
includes the overall Heat Release Rate (HRR) and the ability of the
fire sprinkler system to suppress a fire. Reference 2016 state fire
code section xxx.x.x"
I used xxx to block out any reference to the particular project.
Any ideas on this stuff. We were hired to just design the system
per OH2. This is going to get interesting.
