Extraction Compliance & Safety

Extraction Compliance & Safety

Class I, Div. 1 and Class 1, Div. 2 Compliance and Safety for Extraction

The HAL Extraction Booth was designed to create a safe CID1 working environment for extracting plant oils using flammable or hazardous solvents. The HAL Extraction Hood was designed to create a more affordable CID2 working environment for ethanol extraction, post-extraction processing, and off-gassing.

UL Certified

The use of these flammable and pressurized solvents can create dangerous conditions for workers and buildings. HAL Extraction has worked with Underwriters Laboratories (UL) to develop and certify the first equipment for use in the plant oil extraction industry.

On 7/9/18 the HAL Extraction Booth became the industry’s first and only UL Certified plant oil extraction facility supporting Class I, Division 1, Group D equipment within the booth; and Class I, Division 2, Group D equipment outside the booth around openings for 3 feet in all directions.

In the fast-growing world of cannabis extraction, this certification can expedite your facility’s approval process. 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 workplace, satisfying both Fire Marshals’ and Building Code Officials’ requirements.
