Industrial hygiene is where safety turns into science. Airborne chemicals, noise, heat, dust — the exposures that make workers sick don't always show up in an incident report. They show up in a blood test years later, in a workers-comp claim after retirement, or in a compliance inspection that asks for the sampling record and doesn't find one. OSHA's PELs are legally enforceable, ACGIH's TLVs are widely used as more protective internal targets, and NIOSH's RELs sit alongside both. When exposures approach an action level, the standard triggers monitoring and medical surveillance — and if the sampling record isn't there, the case for compliance isn't there either. Tracking exposure sampling against PELs and TLVs is what turns industrial hygiene from a paper exercise into a working health-protection program. iFactory's Exposure & IH Data Tracking keeps every sample linked to every worker.
iFactory Exposure & IH Data Tracking
Every Sample Logged, Every Worker Protected, Every Limit Tracked
Track exposure sampling against OSHA PELs and ACGIH TLVs. Air, noise, heat, and dust monitoring linked per worker, per job, per shift — audit-ready and health-protective.
Why IH Data Gets Lost
Industrial hygiene sampling generates a lot of records — every sample, every worker, every date, every limit compared against every reading. On paper, those records get scattered across labs, consultants, EHS folders, and eventually a filing cabinet no one opens.
Paper IH Records
"Do we have the noise data for that welding cell?"
Sample results in PDFs from different labs and consultants
No live comparison against PELs or TLVs
Exposure records not linked to specific workers
Trend over time invisible — is exposure up or down?
IH Data Platform
"Every sample lives with the worker, the job, and the limit."
Sample results centralized regardless of who ran the analysis
PEL, TLV, and action-level thresholds shown on every reading
Exposure records tied to worker, job, and shift
Trends over months and years visible per exposure and area
The Exposures That Need Tracking
Industrial hygiene isn't one exposure — it's a portfolio. iFactory holds every category so a worker's cumulative picture is complete.
Air Contaminants
Chemical air sampling against OSHA PELs and ACGIH TLVs — 8-hour TWA, STEL, and ceiling limits tracked per sample.
Limit: PEL / TLV
Noise
Noise dosimetry against 90 dBA PEL and 85 dBA action level per 1910.95, with dose and TWA logged per worker.
Limit: 90 dBA PEL
Heat Stress
WBGT monitoring in hot work environments with acclimatization tracking and heat illness prevention indicators.
Limit: WBGT threshold
Silica & Dust
Respirable crystalline silica against 1910.1053, with sampling triggered by tasks and worker exposure logged.
Limit: 50 µg/m³ PEL
Biological
Blood lead levels, chromate, and other biological monitoring linked to environmental samples and worker exposure history.
Limit: BEI / medical
What the Platform Actually Does
An IH data platform is more than a filing cabinet. It's the system that connects a sample on a lab report to a limit in a regulation to a worker on a shift.
Log
Every sample — air, noise, heat, dust — logged with location, worker, job, date, method, and lab.
Compare
Every reading compared automatically against OSHA PEL, ACGIH TLV, and NIOSH REL with action-level flags.
Link
Samples tied to workers so cumulative exposure per person is trackable across jobs, shifts, and years.
Trend
Long-term trending by area, job, and worker so you see whether controls are actually reducing exposure.
What IH Data Tracking Delivers
When industrial hygiene data lives in a system that connects samples to workers to limits, the plant stops discovering exposure problems in medical surveillance and starts controlling them upstream.

Frequently Asked Questions
How does it handle OSHA PELs vs. ACGIH TLVs?
Every sample is compared against both. The OSHA PEL is what an inspector will enforce; the ACGIH TLV is often more protective and represents current science. iFactory shows every reading against both, plus the NIOSH REL where relevant, so you can see compliance and health protection at once.
Can it link samples to individual workers?
Yes. When a personal air sample or noise dosimeter is worn by a specific worker on a specific shift doing a specific job, that data ties to the worker. Over years the platform builds a cumulative exposure record per person — which is the record medical surveillance actually needs.
Does it flag when exposure approaches an action level?
Yes. Every regulation has an action level below the PEL that triggers surveillance and more frequent monitoring. iFactory flags results at or above the action level so the follow-up sampling and any required medical exams get scheduled before compliance drifts.
Does it handle the full range of exposures — air, noise, heat, dust?
Yes, and that's the point. IH programs fail when air data lives in one system, noise in another, and heat in a spreadsheet. iFactory holds all of them together so the worker's full exposure picture is visible in one place.
Book a demo to see multi-exposure trending on your own data.
Can we start with one site or one exposure type?
Yes. Many operations start with a single site or with one exposure type such as noise or a specific chemical, prove the platform there, then extend across exposures and sites. Book a demo and we'll scope the starting point around your operation.
Stop losing exposure data across labs and consultants.

Bring a recent sampling report from any lab. We'll load it into the platform, plot it against the PEL and TLV, and show cumulative exposure by worker and area.
