A subscription: $19.99 a month or $199.99 a year, everything included from day one. Works entirely offline. No account. Your records never leave the device. The field notebook for people who do the actual work of industrial hygiene, safety and environmental compliance — built by a PhD scientist who spent a career as an EHS and quality director in chemical plants. WALKTHROUGHS AND GEMBA WALKS Log a finding in seconds: photograph it, describe it, tag location and hazard category, cite the standard, set the time to fix, and mark what happens next — corrected on the spot, needs a work order, or held for shutdown. Photos stay with the finding they belong to, and the round exports as a report. Gemba walks get their own mode, with the eight wastes and room for what makes the job hard. NEAR MISS, INCIDENT AND INVESTIGATION Capture a near miss while it is fresh — what happened, and what could have. Record incidents with type, severity, equipment and immediate actions. Then investigate: 5 Whys, a fishbone that draws itself from your contributing factors, a fault tree with AND/OR gates, and corrective actions tracked to closure. EXPOSURE ASSESSMENT — REAL STATISTICS Most safety apps stop at a time-weighted average. This does the distribution. Enter results for a similar exposure group and get the geometric mean and GSD from a lognormal fit, the 95th percentile, the 95%/95% upper tolerance limit and the exceedance fraction — non-detects handled by substitution and reported, not dropped. Then the Six Sigma view: treat the OEL as an upper specification limit and see Ppu, sigma level, DPMO and a control chart that flags an out-of-control day before you average it away. Every assessment states its method, so it survives an audit. FIELD CALCULATORS 8-hour TWA · mixture rule · extended-shift OEL adjustment (Brief & Scala) · noise dose and TWA (OSHA 5 dB and ACGIH/NIOSH 3 dB) · ppm to mg/m³ with temperature and pressure correction · dilution ventilation · sample volume and time · WBGT heat stress. Each states its method and limits plainly. 29 CFR 1910 AND 1926 — SEARCHABLE OFFLINE The full text of the General Industry and Construction standards, with no signal. Search by number or words, and cite a section straight into a finding. The edition date is on screen so you never quote stale regulation. OSHA EXPOSURE LIMITS BUILT IN Look up a chemical by name or CAS number and the OSHA permissible exposure limit fills itself in — Tables Z-1, Z-2, Z-3 and the construction limits, with skin and ceiling notations flagged. SHUTDOWN, TURNAROUND AND ENVIRONMENTAL Findings held for the outage carry forward automatically, alongside the work list, contractors with orientation and insurance status, safety coverage by role and shift, and the training that must happen before the gate opens. Environmental lives in the same notebook: releases with containment and notification status, waste streams with the accumulation clock running against your generator status, and permit obligations. NO SIGNAL, AND NO HOSTAGES Your subscription is confirmed from a receipt on the device, so underground or far from the nearest tower the app behaves the same. And if it lapses, everything you recorded stays put and the export button keeps working — full PDF, full backup, no limits. These are your professional records. We will not hold them hostage.
