1 Scope
1.1This Standard covers commercial and industrial plant oil extraction equipment for installation and useindoors in an ordinary (unclassified) locations and hazardous (classified) locations. Based on theapplication, installation is in accordance with the manufacturer’s installation instructions, together with thefollowing, as applicable:
a) CSA C22.1,Canadian Electrical Code, Part 1(CE Code); ULC-S4400, Premises,Buildings andEquipment Utilized for the Cultivation, Processing and Production of Cannabis; National Fire Codeof 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 GasCode.
1.2 Plant oil extraction equipment includes:
a) Preparatory equipment,for preparing the plant material for extraction of the oil， such astrimming, 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.
1.3 This equipment,along with systems involving any combination of this equipment, is used forextracting oils from plants as instructed by the manufacturer.
1.4The requirements in this standard do not cover the physiological or other attributes or effects thatmay result from the use of this equipment.

a)Exothermic reactions, including self-ignition of dusts.
b) Mechanically generated sparks (generated intentionally).
c) Flames and hot gases (including hot particles).
1.6 This standard does not apply to mechanical means of extraction of plant oils that do not use solvents.
1.7 This standard does cover the connection to external solvent containers or external solvent sources tothe plant oil extraction equipment.
Note: Equipment is a general term including apparatus,fittings, devices, components, and the like used as a part of o n conectionwith, an installation.
