This app provides industrial hygiene and safety professionals with over 35 tools for planning, measuring, and documenting field assessments. It includes features for sound, heat stress, light, radiation, and chemical exposure, with offline reference materials and GPS-tagged data export.
2.6.1
October 15, 2026
Version 2.6.1 brings important calculation corrections and measured WBGT inputs to your industrial hygiene toolkit. - Fall clearance now includes worker height in clearance totals and results. - The NIOSH lifting equation uses corrected frequency and coupling factors and clearly flags tasks outside its range. - STEL and ceiling exposure assessments retain sampled concentrations without full-shift dilution. - Weekly Brief & Scala adjustments use separately entered and saved weekly hours. - Non-detect results with insufficient analytical sensitivity now include follow-up warnings. - Calculate WBGT heat stress from measured natural wet-bulb, globe, and air temperatures. Saved components match the displayed calculation, and estimated readings remain clearly labelled. Previously saved exposure assessments retain their original results. Reassess affected records to apply these corrections.
