Cannabis CO2 Supercritical Extraction System Safety Checklist

This cannabis CO2 supercritical extraction system safety checklist ensures compliance with ASME Boiler and Pressure Vessel Code requirements for high-pressure CO2 vessels, OSHA 29 CFR 1910.1000 CO2 exposure limits, and state cannabis processor license requirements. Supercritical CO2 extraction operates at 1,000-5,000 psi — pressure vessel integrity and CO2 gas detection are life-safety critical requirements.

  • Industry: Cannabis
  • Frequency: Daily
  • Estimated Time: 20-30 minutes

Pressure Vessel Integrity

High-pressure system inspection.

  • Pressure vessels inspected per ASME/state requirements and within inspection date?
  • No visible damage, corrosion, pitting, or cracks on vessel exterior?
  • Pressure relief valves installed, sized correctly, and within test date?
  • All pressure gauges functional and reading accurately?
  • All fittings and connections leak-free (verified with soapy water or leak detector)?

CO2 Supply and Cylinder Safety

CO2 source safety.

  • CO2 cylinders secured upright with chains or straps?
  • CO2 cylinders labeled with contents and pressure?
  • Food-grade or extraction-grade CO2 used (SDS verified)?
  • CO2 supply sufficient for planned extraction runs?
  • CO2 supply regulator functional and within calibration date?

CO2 Gas Detection

Worker protection from CO2 accumulation.

  • Fixed CO2 gas detector installed in extraction room?
  • CO2 detector calibrated within manufacturer interval and certification current?
  • CO2 alarm activating at or below 5,000 ppm OSHA PEL (8-hr TWA)?
  • Ventilation activated or alarm sounds when CO2 level rises?
  • CO2 alarm tested monthly and test documented?

Operating Procedures

Safe operation compliance.

  • Extraction SOP posted and current version accessible to operator?
  • Only trained and authorized operators running CO2 extraction system?
  • No solo operation during active high-pressure extraction (buddy system)?
  • LOTO (Lockout/Tagout) performed before any maintenance on pressurized system?
  • All operating parameters (temperature, pressure, flow) within manufacturer specifications?

Equipment Maintenance

Preventive maintenance.

  • All seals and O-rings inspected for wear and replaced per PM schedule?
  • Inline filters and separators cleaned or replaced per schedule?
  • Equipment maintenance log current with all service entries?
  • Manufacturer-recommended annual service completed?
  • Critical spare parts (O-rings, seals, relief valves) stocked on-site?

CO2 Extraction Records

Documentation.

  • Extraction run log completed for each run with parameters and yields?
  • Pressure vessel inspection certificate on file and current?
  • CO2 detector calibration certificates on file?
  • Any equipment anomalies or CO2 alarms logged and investigated?
  • CO2 Extraction Notes
