UL Certifications & PE Peer-Reviews

UL Certification PSI Reviewed CID1 Lab Room Booth

As of 7/10/18, we are proud to say that the HAL Extraction Booth officially has a UL Certification for Extraction Booths for Use in Class I, Division 1, Group D (C1D1) Hazardous Locations. The 18-month long process to acquire the certification for C1D1 extraction booths was quite humbling, but it truly showed us the gravity of an NRTL listing. The coveted listing from UL, the oldest and most respected Nationally Recognized Testing Laboratories (NRTL), indicates that a piece of equipment has been deemed safe for use in an applicable working environment, and UL has tested the product to meets specific, defined requirements. These requirements are often based on UL’s published and nationally recognized Standards for Safety, satisfying both Fire Marshals’ and Building Code Officials’ requirements.

The release and adoption of NFPA 1 Ch. 38 requires that cannabis extraction equipment be listed, or for equipment without a listing, to have a 3rd party Professional Engineering Peer-Review. Before HAL Extraction received our UL Certification, there were no listed C1D1 Extraction Booths/Labs/Rooms.

Similar to the UL listing and certification process, 3rd Professional Engineering Peer-Reviews indicate that a professional engineer has (through the peer review process set forth by the National Society of Professional Engineers) evaluated and verified a design by another engineer/designer. Regarding the cannabis extraction industry, this will typically constitute verification that a piece of equipment was design, manufactured, and installed in accordance with all applicable Fire and Building codes, including but not limited to:

International Fire Code 2018

International Mechanical Code, 2018

Typically, your Authority Having Jurisdiction (AHJ) will have no problem approving equipment with a UL Certification. However, listed equipment designed for cannabis extraction is new territory for a good number of AHJs. We guarantee that our peer-review, in conjunction with the UL Certification, will lay to rest any concerns that your AHJ may have about your brand new C1D1 Extraction Booth.
