IoT temperature and humidity sensors that track humidex and heat-stress risk continuously — with automated alerts, audit-ready logs, and compliance aligned to OSHA and Ontario guidelines.
A complete heat-stress safety stack — from the sensor on the wall to the report on the inspector's desk.
Industrial-grade wireless sensors capture temperature and humidity for humidex and heat-stress monitoring across the work area.
Set thresholds per site or sensor and trigger multi-channel alerts — email, SMS and in-app — the moment risk crosses your limits.
Live dashboards and automated logging, with exportable compliance reports and trend charts ready for audits and reviews.
Continuous risk scoring using the Heat Index and Humidex, mapped to recognized occupational response zones.
Actionable guidance at each threshold — water, rest breaks, cooling, and shift adjustments — so teams know exactly what to do.
Manage many facilities from one account with role-based access for safety leads, supervisors, and site managers.
We place wireless sensors in your work areas. Hardware rental is included in your subscription — no capital outlay.
Configure humidex / heat-index limits per site, aligned to OSHA and Ontario response zones.
Conditions stream to live dashboards. When risk rises, the right people are alerted instantly.
Every reading is logged. Export audit-ready reports and trend analyses on demand.
Live 7-day humidex forecast from real weather data, mapped to the OHCOW / CCOHS workplace response zones. Check your city — then remember your plant floor runs hotter.
Indicative only. Workplace humidex must be based on actual measurements taken in the work area. Source: CCOHS / OHCOW.
Worknosis maps your live readings to the OHCOW humidex response zones referenced by CCOHS — so the right action is always one glance away.
| Adjusted humidex | Degree of risk | Recommended response |
|---|---|---|
| 25–29 | Comfortable | Supply water to workers on an "as needed" basis. |
| 30–33 | Some discomfort | Post heat-stress alert; encourage extra water; start recording hourly temperature & humidity. |
| 34–37 | Discomfort | Alert notice; direct workers to drink extra water; ensure training to recognize symptoms. |
| 38–39 | Significant | 15 minutes relief per hour; cool water (≈1 cup every 20 min); symptomatic workers seek medical attention. |
| 40–41 | Great discomfort | 30 minutes relief per hour, plus all measures above. |
| 42–44 | High | If feasible, 45 minutes relief per hour, plus all measures above. |
| 45 + | Dangerous | Only medically supervised work can continue (manage per ACGIH TLV®). |
Adapted from the OHCOW Humidex-Based Heat Response Plan as published by the Canadian Centre for Occupational Health and Safety (CCOHS). Always follow your jurisdiction's legislation and never ignore heat-stress symptoms regardless of the reading.
When heat combines with hard physical work, fluid loss, and fatigue, it can lead to heat exhaustion, heat stroke, and even death. Continuous monitoring detects risk early and drives proactive action — reducing incidents and strengthening compliance.
Audit-ready logs and trend reports mapped to the frameworks your inspectors and safety committees already use.
Employers already owe "every precaution reasonable" under OHSA s. 25(2)(h). Continuous in-area monitoring with humidex response zones is defensible evidence of that duty — especially during MOL summer heat blitzes.
Bill 36 would mandate a formal Worker Heat Protection Standard: heat-stress policies, regular assessments, mandatory breaks, and training. Deploying monitoring now means you're ready the day it passes.
Québec's occupational health regulation imposes specific heat-exposure requirements, including temperature measurement obligations in larger workplaces. Automated logging makes compliance continuous, not seasonal.
WorkSafeBC requires heat-stress assessments and exposure plans where workers may be at risk. Worknosis provides the measured data those assessments must be built on.
Supports the heat-index trigger points in OSHA's heat injury & illness prevention rulemaking — initial measures at ~80 °F and high-heat controls (rest breaks, monitoring) at ~90 °F.
Implements the humidex-based response plan referenced by CCOHS, using actual in-area measurements rather than weather-station data.
Worknosis isn't a prototype. Our heat- and humidity-monitoring system has been in the field for more than 12 years, with Ontario manufacturing facilities — from stamping and tooling plants to multi-site operations — relying on it to protect workers, reduce incidents, and stay ahead of compliance. We've refined it shift after shift, summer after summer — so you get a platform that already works in the real world.
Talk to our teamOne predictable annual rate. Hardware rental, monitoring, alerting, dashboards, and compliance reporting — all included. Every additional sensor costs less.
Whether you're protecting one production line or a dozen facilities, pricing is transparent: your first sensor covers the platform, and every extra work area is just $600/year. Estimate your cost, then request a tailored multi-site quote.
Tell us about your facility and we'll prepare a tailored quote — usually within one business day. Questions about deployment, compliance, or multi-site rollouts? We're happy to help.
