About Hazel B. McClure

In 2014, Hazel B. McClure led the first third-party safety audit of a commercial butane hash oil (BHO) lab in Colorado, uncovering three critical ignition pathway failures that had gone undetected by existing fire code inspections. Her report didn’t just flag hazards; it introduced the 'solvent retention index,' a field-validated metric now embedded in ASTM D8397 for residual hydrocarbon quantification in cannabis concentrates. Trained as a process safety engineer at Dow Chemical before pivoting to cannabis regulatory science, she insists on treating extraction not as artisanal craft but as continuous-flow chemical manufacturing, where vapor pressure curves, static dissipation protocols, and real-time GC-FID validation aren’t optional extras but prerequisites for worker survival. She’s testified before state legislatures arguing that 'solventless' labeling laws must require certified analytical verification, not marketing claims, and has trained over 170 lab technicians using her proprietary 'hazard mapping' framework that overlays thermal runaway thresholds with facility HVAC schematics.

Frequently Asked Questions

Did Hazel B. McClure develop any widely adopted safety standards for cannabis labs?
Yes—she co-authored the 2017 National Fire Protection Association (NFPA) Supplemental Guidance for Cannabis Extraction Facilities, which became the technical basis for California’s Title 19 emergency regulations. Her solvent classification matrix—distinguishing Class IA vs. modified Class IB hydrocarbons based on boiling point, vapor density, and flash point depression in botanical matrices—is now required in 12 state licensing applications.
Has Hazel B. McClure published peer-reviewed research on cannabis extraction hazards?
She has six first-author papers in the Journal of Occupational and Environmental Hygiene and Process Safety Progress, including a landmark 2020 study tracking real-time isobutane accumulation in unvented purge rooms using laser diode absorption spectroscopy—data that directly revised OSHA’s permissible exposure limit recommendations for branched alkanes in botanical processing.
What’s Hazel B. McClure’s stance on home-based cannabis extraction?
She publicly opposes it, citing empirical data from her 2015–2019 incident database showing 83% of residential extraction fires involved non-rated equipment operating outside its design envelope. In congressional testimony, she argued that ‘kitchen-counter extraction’ violates fundamental process safety principles—specifically, the absence of independent pressure relief, inerting capability, and operator training—making it categorically distinct from industrial practice.
Does Hazel B. McClure work with international regulators on cannabis safety?
She advised Health Canada’s 2018 Good Production Practices framework for licensed processors and helped draft Mexico’s 2022 Norma Oficial Mexicana NOM-265-SSA1-2022 on solvent residue limits. Her cross-jurisdictional work emphasizes harmonizing analytical thresholds—not regulatory philosophy—so that a 500-ppm residual butane limit means the same thing whether measured in Vancouver, Berlin, or Guadalajara.
