Live in five steps.
Three to six weeks.
Standard engagement is three to six weeks from systems assessment to live operator portal. Each step is independently scoped — you can pause, expand, or accelerate. Click any step below to see what happens.
Systems assessment
We start by mapping your facility as a system, not a list of zones. We document the workflow patterns, identify heat sources, audit existing data infrastructure (SCADA, ERP, HRIS, CMMS), and produce a written engagement scope before any instruments are shipped. Delivered as a site visit or remote session. No retainer or commitment required to start.

Every measurement traces back.
Every model is validated.
We bring Lean Six Sigma engineering rigor to thermal diagnostics. Every reading is calibrated, every model is validated against held-out data, and every recommendation includes a rollback plan. We publish the R² so you can audit the fit. We document instrument calibration so OSHA can audit the trail.
◉ Measure
Calibrated instruments
NIST-traceable WBGT meters, FLIR-certified drone thermal, BlueMaestro sensors at ACGIH-compliant placement. Every reading auditable.

Built to satisfy the auditor,
not just the buyer.
The same documentation that drives our compliance reports is what your OSHA inspector wants to see. We don't generate it after the fact — it's the audit trail built into the system from day one.
ACGIH TLV-WBGT
Work-rest regimens per metabolic rate category. Threshold matrix configured per zone.
OSHA General Duty
Heat illness prevention documentation. Audit trail with timestamps, instrument IDs, and signed events.
NIOSH REL
Occupational heat exposure limits. Worker acclimatization tracking for new hires and shift changes.
ISO 7243:2017
Hot environments WBGT index — international standard for heat-stress assessment in workplaces.
AUDIT TRAIL · BUILT-IN
Every WBGT reading, every alert, every intervention is timestamped, instrument-attributed, and signed. Export-ready for OSHA inspections, insurance audits, or internal review. We hand off the documentation methodology so your EHS team can defend the data without us in the room.
The engagement doesn't end at go-live.
Real industrial deployments need maintenance, recalibration, and re-validation. Our continuous-intelligence plan covers all of it — and the model gets sharper with every season.
