For Agencies & Survey Programmes
Record survey data and produce rigorous, presentation-ready Bayesian exposure reports — built on the methodology used in Expostats and trusted by occupational hygienists worldwide, developed in collaboration with a world leader in the field from the Université de Montréal. Use HazNode® for the full workflow, or for the statistics and reporting alone.
From Survey Data to Defensible Report
Whether you run a national survey programme or a single campaign, HazNode® takes recorded exposure data and produces analysis you can stand behind — and a report you can hand to a minister, a board, or a regulator.
Bring the data you already have.
Record survey measurements directly, or bring in existing datasets — each result structured against its SEG, agent, method and OEL so the analysis has the context it needs.
What you get
Structured survey data capture
Existing datasets organised by SEG and agent
Results aligned to the relevant OEL
The methodology hygienists trust, without the spreadsheet.
Distribution fitting, percentiles, exceedance fractions and OEL comparison run on a Bayesian engine built on the Expostats methodology — developed with a world-leading expert from the Université de Montréal.
What you get
Bayesian distribution fitting and credible intervals
GM, GSD, percentiles and exceedance fractions
OEL comparison with transparent assumptions
Hand it to a board, not just a hygienist.
Turn the analysis into clean, consistent, presentation-ready reports — so survey findings are clear to decision-makers, not buried in raw output.
What you get
Clear, consistent report output
Charts and findings built for non-specialists
Consistent format across analysts and campaigns
A method you can put your name to.
A transparent, peer-respected methodology applied the same way every time means findings are defensible and comparable across programmes, regions and analysts.
What you get
Transparent, documented methodology
Comparable results across campaigns
Findings that hold up to external review
Sound Familiar?
Survey data lives in spreadsheets nobody fully trusts.
Real statistics need a specialist and a separate tool.
Formatting the report takes longer than the analysis.
Methodology is hard to explain and harder to defend.
Results aren’t consistent between analysts or campaigns.
Findings are hard to share with decision-makers.
Where The Value Lands
Agencies and survey programmes need findings that are credible, produced quickly, and consistent over time. That is exactly what a built-in, peer-respected statistical engine delivers.
Bayesian methods from the Expostats lineage, developed with a world leader from the Université de Montréal, give findings real authority.
Analysis and presentation-ready reporting come from the same data, collapsing days of formatting into minutes.
One methodology, applied the same way every campaign, so results are comparable across years, regions and analysts.
30 minutes. Bring a recent survey dataset and we'll show the Bayesian analysis and report HazNode® produces from it.
