Occupancy for marijuana prep building.

[SprinklerDesigner2]

This is new for me but I guess it is legal in the state where it is being built.

20,000 sq ft metal building but other than that details are very sketchy.

They are calling it a Hemp manufacturing facility but it is marijuana.

Ordinary Hazard Group II?

Anyone else do anything like this?

We've done a few of these grow facilities. They have been specified as OH2. The extraction areas may be EH2, but are typically a very small area and don't have a huge impact.

Travis,

What do the extraction areas do?

They are pulling the oils from the product. That is my understanding.

THC extraction processes vary. Some processes use liquid carbon dioxide and some utilize a hydrocarbon such as unodorized butane or propane. Listed THC extraction equipment is available in the market place - in other cases, the THC equipment is fabricated by people who know marijuana but have no engineering skills in the design or hazards of this process. I recommend a review of NFPA 36, Standard for Solvent Extraction Plants, for guidance on the design of the automatic sprinkler system once the selected solvent is identified.
