Executive TL;DR
Wearables in the factory promise to detect thermal stress, fatigue, falls, or localized vibration exposure. In enterprise, the pilot fails when IT buys hardware without an OHS use case approved by engineering and medicine. NR-6 still governs what is true PPE; a sensor stuck on the arm does not automatically replace engineering controls. LGPD and collective agreements may limit continuous monitoring. Data should feed the PGR as an indicator, not as a disguised discipline tool.

Device types and realistic promises
Thermal and heart rate wristbands help hydration campaigns in heat. Helmets with beacons improve location in emergencies. Exoskeletons reduce shoulder load if fit is ergonomic — otherwise they worsen MSDs.
NR-6, certification, and interoperability
If the supplier calls it PPE, require CA and label per current legislation. A sensor attached to a helmet may invalidate certification if drilling is not approved by the original manufacturer.
Operations: battery, failure, and false alarms
Define an SLA for wristband replacement on 12x36 shifts. Constant alarms lead users to disable them — UX matters as much as the algorithm.
Privacy and union dialogue
Legal basis for health data processing in a corporate group may be legitimate interest with safeguards — legal counsel must stamp a DPIA. CCT may require anonymization of individual indicators on manager dashboards.
Predictive integration with maintenance and OHS
Heatstroke risk may pause the line if combined with IBUTG humidity — but local meteorological source matters. Correlate with PCMSO for awareness campaigns, not punishment.
Centralized procurement pitfalls
- One-size wristband excludes women.
- Cloud outside the country without Schrems clause.
- Vendor lock-in without open CSV export.
- Not defining data ownership between headquarters and operations.
- Training leaders not to use dashboards as covert surveillance.
FAQ
Are wearables mandatory?
Only if internal policy or agreement — no generic NR.
Do they replace occupational hygiene?
No; they complement measurement when validated.
What about LGPD?
Consent is not always the only basis — evaluate case by case.
