Occupational hygiene software, built for consultancies.
Quoting, projects, fieldwork, sampling, exposure statistics and lab management on one data layer — not a corporate EHS platform with a hygiene module bolted on. Built by consultants who do the work, not desk-sitters.

Built for a consultancy
Built for consultancies, not EHS departments.
Most industrial hygiene software is built for one company looking after its own workers. A consultancy has a different shape of problem: many clients who must stay separate, work that is quoted before it is done and invoiced after, and a report at the end that carries your name rather than theirs. HazNode® is built around that difference.
Every client, separated
Sites, people, substances and exposure history sit inside the client they belong to. Nothing leaks between the jobs you run, and nothing has to be untangled before a report goes out.
Quoted, delivered, invoiced
A quote becomes a project, the project carries the fieldwork and the lab work, and the invoice comes off the back of what was actually done — one chain instead of four systems that have to agree.
Reports built from the data
The deliverable is generated from the samples, results and statistics already in the system, rather than retyped into a document at the end of the job.
Everything, Connected.
One platform to run your entire OHS consultancy.
HazNode® connects every part of your operation, from field sampling to financials, in one cohesive workflow. What began as an internal consultancy tool is now the backbone for hygiene professionals worldwide.
Quotes → Projects
Link consumables, lab analysis, and equipment directly into quotes.
Equipment Tracking
Know where every instrument is, when it is due for calibration, and how often it is used.
Consumables Management
Handle filters, cassettes, and part numbers with full traceability.
Internal Laboratories
Manage chain of custody, analysis requests, and results in one place.
Survey & Exposure Data
Record, track, and trend worker exposure history with integrated Bayesian analytics.
Financial Clarity
Real-time visibility of cost, margin, and project performance.
The statistics
Exposure statistics you can defend.
Exposure statistics in HazNode® are built on the WebExpo / Expostats Bayesian methodology (IRSST report R-1065, Lavoué et al., 2020), developed by a team led from the Université de Montréal. You get the 95th percentile, the exceedance fraction and an AIHA exposure category with credible intervals around them — the numbers an assessment has to stand on when it is questioned, rather than an arithmetic mean of whatever was collected.
It runs on the samples already in the system, against the similar exposure groups you have already defined. There is no export, no second tool, and no re-keying between the sampling record and the statistics that interpret it.

Why HazNode® Exists
It started with too many spreadsheets.
When we moved into occupational hygiene, we faced the same problem as everyone else: disconnected spreadsheets and systems that couldn’t scale. Tracking equipment, samples, and budgets was slow and messy, with data always at risk.
So we built the software we wished existed — and now
it’s available to everyone.
Do you also manage your own workers?
HazNode® Safety covers inspections, forms, incidents, observations, contractors and a hazardous substance register for organisations looking after their own people. It shares the same record of sites, people and substances as the consultancy platform.
