The extraction of cannabis oil can pose many safety issues, including the risk of fire and explosion. In many cases, the extraction process itself creates a hazardous (classified) location due to the use of flammable solvents such as butane, pentane, hexane, propane, and ethanol, which can be released during the processing and extraction of plant oils. Article 512 has been added to the NEC to assist in the safe installation of equipment and systems utilized for cannabis oil extraction within commercial and industrial facilities.
Here is the scope of the new section:

512.1 Scope.
This article covers cannabis oil preparatory equipment, extraction equipment, booths, post-processing equipment, and systems using flammable materials (flammable gas, flammable liquid–produced vapor, combustible liquid–produced vapor) in commercial and industrial facilities.

Informational Note No. 1:
See ANSI/UL 1389, Plant Oil Extraction Equipment for Installation and Use in Ordinary (Unclassified) Locations and Hazardous (Classified) Locations, for information on cannabis oil equipment and systems for hazardous (classified) locations.
Informational Note No. 2:
See NFPA 1, Fire Code; NFPA 55, Compressed Gases and Cryogenic Fluids Code; NFPA 58, Liquefied Petroleum Gas Code; and ICC IFC, International Fire Code, together with the manufacturer’s installation instructions, for information on the installation of cannabis oil equipment and systems.
