Built for refinery EHS managers; speaks the language procurement evaluators shortlist on. Every signal Pactwell reasons across maps to a named API 754 Process Safety Performance Indicator tier or an OSHA PSM element under 29 CFR 1910.119 — so the audit-ready PDF the platform writes at the moment of the breach is the same evidence an external auditor opens.
Why Pactwell on a refinery floor
API 754 Tier 1 / 2 / 3 PSPI logging and OSHA PSM 14-element coverage are not aspirational — they are the standards your inspection opens against. Pactwell’s sensor + permit + CCTV correlator writes to those standards directly, so the evidence pack is the same pack your auditor opens.
API 754 · Tier 1 / 2 / 3 PSPI
Pactwell captures the loss-of-primary-containment precursor (Tier 1), the challenge to safety systems (Tier 2), and the operating-discipline narrative entry (Tier 3) with a timestamped sensor reading, permit state, and CCTV frame — the evidence pack an auditor asks for, written before the report is filed.
OSHA PSM · 29 CFR 1910.119
Operating procedures, mechanical integrity, hot work, permit-required confined spaces, management of change, control of work, incident investigation — every element a refinery EHS manager signs for maps to a defined Pactwell input combination, so coverage is defensible at audit time and demonstrable bay by bay.
Sour gas · hot work · break-in
Hydrogen sulfide exposure tracking against the entry and respiratory-protection permit you already run. Hot-work permits near live process units, with the thermal imaging and wind/weather sensor live at the moment welding starts. Vessel entry and break-in work, attended by the CCTV the gate permit already references.
Inputs → outputs
The matrix below pairs the inputs Pactwell reasons across — gas sensors, vibration sensors, thermal imaging, contact sensors, the permit registries you already run, and the CCTV feeds pointed at the work face — with the refinery signal each combination reasons over and the compliance output the audit-ready PDF references.
Refinery signal Pactwell reasons across
H2S excursion reading above the action level while a worker is inside the permit envelope, with no falling-edge scrubber log in the same window.
Compliance output
Refinery signal Pactwell reasons across
Combustible-gas reading crosses LEL inside a closed permit window with the attendant away from the access point for the threshold interval.
Compliance output
Refinery signal Pactwell reasons across
Ignition detected outside the unlit flare envelope during a hot-work permit window, with wind direction carrying toward a live process unit.
Compliance output
Refinery signal Pactwell reasons across
Vibration signature crosses the alert band on a piece of equipment whose LO/TO permit window is still open at the controller level.
Compliance output
Refinery signal Pactwell reasons across
Door or perimeter contact opens outside the permit-issued roster, with no escort badge crossing the same reader within the audit window.
Compliance output
Refinery signal Pactwell reasons across
Flare tip thermal anomaly persists past the relief event with the relief valve state held open — a sustained release, not a transient.
Compliance output
Compliance citations are written against the published standards — API Recommended Practice 754 (Process Safety Performance Indicators) and OSHA 29 CFR 1910.119 (Process Safety Management of Highly Hazardous Chemicals). Pactwell capability claims cross-check against the competitor matrix and the enterprise FAQ.
Run the correlator on the highest-risk bay
If you already have the gas sensors, the permit registry, and the CCTV feeds online, run the same pilot the matrix above is written against — connect sensors, register permits, point Pactwell at the VMS, and watch a flagged incident arrive inside two weeks. If you’re still evaluating the shortlist, the door for that is open too.
