scope:

This Standard covers commercial and industrial plant oil extraction equipment for installation and use indoors in an ordinary (unclassified) locations and hazardous (classified) locations. Based on the application, installation is in accordance with the manufacturer's installation instructions, together with the following, as applicable:

a) CSA C22.1, Canadian Electrical Code, Part 1 (CE Code); ULC-S4400, Premises, Buildings and Equipment Utilized for the Cultivation, Processing and Production of Cannabis; National Fire Code of Canada (NFC); and CSA B149.1, Natural Gas and Propane Installation Code; and

b) NFPA 70, National Electrical Code (NEC), International Fire Code (IFC), NFPA 1, Fire Code, NFPA 55 Compressed Gases and Cryogenic Fluids Code, and NFPA 58, Liquefied Petroleum Gas Code.

Plant oil extraction equipment includes:

a) Preparatory equipment, for preparing the plant material for extraction of the oil, such as trimming, deseeding, and drying/curing;

b) Extractors, for removing the oil from the plant material by the use of Liquefied Petroleum Gas (LPG), butane, propane solvents, ethanol or pentane (flammable solvents) and Carbon Dioxide (CO2) (non-flammable solvent);

c) Extraction booths or pods, for enclosing/protecting plant oil extraction equipment; and

d) Post-processing equipment, for finalizing the plant oil extraction process such as vacuum ovens, rotary evaporators, and solvent recovery pumps.

This equipment, along with systems involving any combination of this equipment, is used for extracting oils from plants as instructed by the manufacturer. 1.4 The requirements in this standard do not cover the physiological or other attributes or effects that may result from the use of this equipment.

This standard does not apply to equipment involving the following risks of ignition:

a) Exothermic reactions, including self-ignition of dusts.

b) Mechanically generated sparks (generated intentionally).

c) Flames and hot gases (including hot particles).

This standard does not apply to mechanical means of extraction of plant oils that do not use solvents.

This standard does cover the connection to external solvent containers or external solvent sources to the plant oil extraction equipment.

Note: Equipment is a general term including apparatus, fittings, devices, components, and the like used as a part of, or in connection with, an installation.
