What Pressure Safety Inspectors does
Pressure Safety Inspectors (legally Pressure Safety Inspectors, LLC) is a for-profit, privately held engineering consultancy founded in 2014 and based in Colorado (Castle Rock/Denver), with 11-50 employees. The company provides third-party field verification, engineering peer reviews (Technical Reports), and safety-compliance consulting exclusively to the cannabis and hemp extraction industry. Its work evaluates hydrocarbon, CO2, and ethanol extraction equipment and full facility footprints—covering electrical systems, ventilation, egress, and hazardous area classifications—against NFPA, OSHA, and state-specific safety standards, working directly with Authorities Having Jurisdiction (AHJs). The firm claims 5,000+ extraction-related consultations since inception and operations across 50 US states, DC, and 5 countries.
The core offering is organized as an integrated service platform spanning Equipment Reviews, Facility Compliance (Process Hazard Analysis, Dilution Analysis, Field Verification, Technical Assistance Reports), and OEM Technical Reports, coordinated by a Compliance Roadmap that culminates in an official Approval Document usable in jurisdiction inspections. A distinctive asset is the public System Approvals listing of OEM equipment models that have passed PSI verification, which serves as a reference for local authorities and a marketing hook for equipment manufacturers. There is no software product, API, or AI component; the value derives from licensed Professional Engineers and regulatory domain expertise.
The business model is fee-based professional services, sold via direct enterprise/field sales and initiated through website contact-form inquiries (requesting extractor types, quantities, and solvents used). Pricing is quote-based and not publicly disclosed. Primary customer segments are multi-state cannabis operators (e.g., Verano, Trulieve, Cresco Labs, Curaleaf, Green Thumb Industries), cannabis extraction OEMs, and individual extraction facilities. The company is founder-controlled with no disclosed external investors, parent, or funding rounds, consistent with a bootstrapped operating model. Leadership comprises Professional Engineers including CEO Chris Witherell and founding partner John R. Andrzejczak, with Brad Crotzer leading the engineering team since 2017.

Pressure Safety Inspectors competitors and assessment
Company assessmentOthers
- Exponent: Engineering and scientific consulting firm providing failure analysis, regulatory compliance, and process safety expertise. Comparable to PSI's process safety / PHA work as an engineering consulting peer, though operating at much higher price points and across many industries beyond cannabis.
- EFI Global: Engineering and fire-origin investigation firm providing facility and equipment inspections, code-compliance analysis, and loss-prevention consulting. Comparable as a peer in fire-protection engineering reviews for industrial facilities.
- Tetra Tech: Environmental and engineering consulting firm with industrial compliance, EHS, and facilities services practices. Comparable as a peer for facility safety assessments, hazardous-area classification, and code-compliance work that PSI delivers for cannabis extraction facilities.
- Rimkus Consulting Group: Forensic engineering and consulting firm offering process safety, code-compliance, and facility assessment services. Comparable as a peer in facility safety assessments and Process Hazard Analysis delivered by licensed engineers.
Broad incumbents
- Bureau Veritas: Global TIC provider with established industrial-services and pressure-equipment inspection practices. Comparable as a high-scale incumbent in the same inspection/certification category PSI occupies for cannabis extraction equipment.
- UL Solutions: Safety-science certification and standards body that lists industrial equipment and provides code-compliance services. Comparable to PSI's approved-systems listing function, but as a general-purpose TIC incumbent not specialized in cannabis extraction.
- TÜV SÜD: International TIC services group offering pressure-equipment inspection, process safety, and industrial facility certification. Overlaps with PSI's pressure-equipment review and facility compliance services at much larger scale and broader industry coverage.
- SGS: World-leading TIC services group providing inspection, testing, and certification for industrial processes and pressure equipment. Comparable to PSI's equipment-review services but as a broad incumbent across many regulated industries rather than a cannabis specialist.
- Intertek: Global testing, inspection, and certification (TIC) firm serving oil & gas, chemical, and industrial process clients. Operates in the same ITC-for-energy-infrastructure space as PSI's pressure-equipment reviews, but at vastly greater scale and across all hazardous process industries rather than cannabis specifically.
Direct peers
- Jensen Hughes: National fire protection engineering and code-consulting firm that performs independent code-compliance analysis, hazard analysis, and field verification for regulated facilities. Directly comparable as a peer in fire-protection engineering reviews, Process Hazard Analysis, and AHJ-facing compliance work that PSI executes for cannabis extraction facilities.
