IH Toolbox
Built by CIH/CSP Professionals • Field-Tested
The complete industrial hygiene and occupational health toolkit featuring 35+ professional measurement tools, international exposure limit databases, and comprehensive exam preparation modules.

OSHA and NIOSH criteria, using the same equations IH Toolbox ships with. Enter each level you measured and how long you were in it.
Specification
What it does
IH Calculators
IH Equation Solver, NIOSH Lifting Equation, Ventilation Rate Calculator, Fall Clearance, Chemical Mixture TLV, and Scientific Calculator.
International OEL Database
Access 25+ occupational exposure limit references including OSHA PEL, NIOSH REL, Cal/OSHA, UK WEL, Australia WES, and more.
GPS-Tagged Measurements
All measurements automatically tagged with GPS location data for comprehensive field documentation and reporting.
Reference Library
NIOSH Pocket Guide, Respiratory Protection Guide, Fire Extinguisher Selector, Chemical Storage Guide, and Safety Sign Decoder.
Projects: The Sample Record
A tab for the work around the numbers. Organize surveys into projects and sites, log air, noise, wipe and bulk samples, and see at a glance what is running and what is waiting on a lab.
Run Samples, Not Just Plan Them
Save a plan from the Air Sampling Planner and start a run from it. The clock handles pauses, and the pre/post calibration pair is checked against the 5% drift limit most NIOSH methods allow.
Exposure, Not Just Results
Enter what the lab reported and get the calculated exposure against the applicable limit — with Brief & Scala or OSHA shift adjustment, explicit handling of unsampled time, and a plain-language explanation of how the number was reached.
Any Lab, Any Pump
Import results from any laboratory’s CSV by mapping its columns once. Instruments are recorded by make, model and serial number, so the record never depends on whose hardware or whose lab you used.
Screening Data Stays Labelled
Readings taken with the phone’s own sensors are marked as field screening throughout, and on every page of an exported report. They are never presented as compliance documentation.
Survey Reports
Generate a multi-page exposure survey report: sample summary, the full chain behind each result, and an appendix stating the assumptions applied so the numbers can be reproduced.
CIH/CSP Exam Prep
CIH and CSP question banks are included in Pro — no longer a separate purchase. Anyone who already bought the standalone add-on keeps their access permanently.

Operators
Who Uses IH Toolbox
Built for the people who actually take the readings
Industrial Hygienists
CIHs and IH technicians running walkthrough surveys, noise dosimetry, and heat stress assessments who need defensible numbers without hauling a full instrument kit to a scoping visit.
Safety Managers & EHS Staff
Site safety leads who need a fast, credible answer on ventilation, confined space entry, or an ergonomics complaint before deciding whether a formal survey is warranted.
Military & Government Preventive Medicine
Bioenvironmental engineering and preventive medicine teams working blast overpressure, WBGT, and non-ionizing radiation in the field, often without connectivity.
Consultants & Sole Practitioners
Independent IH consultants who bill by the hour and need GPS-tagged measurements and PDF exports that go straight into a client report.
CIH & CSP Candidates
Certification candidates using the calculators and reference library to build intuition for the equations and exposure limits the exams actually test.
Facilities & Operations Teams
Plant and facilities staff verifying containment pressure differentials, lighting levels, and airflow between formal assessments.

Common questions
N-01Does IH Toolbox replace calibrated instruments?
No, and it is not marketed as a substitute for calibrated, certified equipment. The sound level meter, light meter, and environmental tools use your device's sensors, which makes them excellent for screening, scoping, and triage — deciding where a full survey is warranted. For compliance sampling and any measurement that becomes a legal record, use calibrated instrumentation.
N-02How many tools are actually included?
35+ tools across measurement, calculation, and reference. That covers a sound level meter with TWA and A-weighting, WBGT heat stress with weather integration, light meter, anemometer, vibration, blast overpressure, pressure differential, UV and cold stress, plus specialty modules for radiation, non-ionizing radiation, chemical mixture OELs by the ACGIH TLV method, air sampling planning, ventilation, confined space, and RULA/REBA ergonomics.
N-03Does it work without a signal?
Yes. The reference library — 25+ global OEL standards including OSHA, NIOSH, and international sources, plus respiratory protection guidance and chemical compatibility data — is bundled in the app. Measurements and calculations run offline. Only weather-integrated WBGT inputs need a connection.
N-04Can I get my data out?
PDF and CSV export are built in, and measurements are GPS-tagged so locations stay tied to readings. iCloud sync keeps work in step across your devices.
N-05Is it really free?
Pro is a single lifetime purchase covering everything in the app, with a discounted price for verified service members. Calculators, live meters, OSHA PEL references and checklist templates stay free, and you can save three measurement sessions before Pro is needed. CIH and CSP exam prep is included in Pro rather than sold separately.
N-06Can I manage a whole sampling campaign in it?
Yes, as of version 2.5. Projects organize surveys into sites, and a saved plan from the Air Sampling Planner can be started as a live run — the clock handles pauses, and the pre/post calibration pair is checked against the 5% drift limit most NIOSH methods allow. Enter the lab result and you get the calculated exposure against the applicable limit, with Brief & Scala or OSHA shift adjustment and explicit handling of unsampled time.
N-07Will a phone reading end up in a compliance report by mistake?
No. Readings taken with the phone’s own sensors are labelled as field screening everywhere they appear, including on every page of an exported report. Lab-analyzed results and phone screening are kept visibly distinct, so the two never get conflated in documentation.
N-08Which iPhone sensors does it use?
Microphone for sound level and dosimetry, camera for light metering, barometer for pressure differential, and the motion sensors for vibration. Accuracy depends on your device hardware, so calibrate against a known reference when the number matters.
