Got any information on what a cannabis extraction facility would fall under design-wise per NFPA 13?
The facility is less than 5,800 sf and may not need anything per the AHJ but I want to be sure what the correct hazard classification should be in case they do decide to put a sprinkler system in, should anyone have information more than what an "agricultural facility" is listed in 13. Thanks in advance. Posted anonymously for discussion. Discuss This | Submit Your Question | Subscribe

It depends on the extraction process. There is a mechanical press process, a CO2 process, and a butane extraction process. Prior to my current job, I was a high protected risk engineer for insurance and we surveyed a lot of CBD processors. The hazard class will be governed by the overall process. Its likely the system would be designed to OH2, with a pocket of a higher density of EH2 for the butane extraction.

I agree with the other comments. The butane extraction process is quite hazardous and needs good controls beyond just ceiling sprinkler protection. Even the CO2 has issues with design concentrations and tenability. I guess what i am saying is that, depending on the process, this is an EH2 area and ceiling protection design is not your only issue.

Not an expert in this area, but I enjoyed the NFPA Journal a few years back where the cover was a large cannabis plant. Kept that on my desk as a conversation starter for a while.

Handled one of these a couple years ago using the butane (including propane) process. Extremely hazardous as the two gases are not odorized. As stated above the process will dictate the hazard classes to be considered for use.

-The process and hazards present drive the sprinkler classification. The ventilation requirements and fire separation are also important to the determination. My experience has shown the bio mass is not the driving factor, but the chemicals and process utilized for extraction. We recently worked with a pressurized ethanol extraction process that was at approximately 60°F.

I believe the ICC has a relatively new document that address'all aspects of these facilities. You may check their site. I know several AHJ's who are using the document and have found it cover all aspects thoroughly.

Hazardous Solvents are frequently used for plant oil extraction and post extraction oil refinement. the 2 most common solvents used for Initial oil extraction are: Leave a Reply. |
