A confined space technician's heart rate hit 142 bpm and skin temperature rose 2.3°F forty minutes into a 36-inch pipe inspection on a refinery hydrogen unit — early heat stress he did not yet feel. Under traditional monitoring, the hole-watch would rely on radio check-ins and the technician's subjective "I'm fine." He would have collapsed at minute 62, triggering emergency extraction and a 3-day OSHA shutdown. Instead, a $380 wearable on his wrist streamed biometric data to the safety officer's tablet. Amber alert at minute 40. Technician exited at minute 42. Zero injury, zero rescue, zero delay. Wearable technology detects the physiological failures humans cannot self-diagnose — before they become injuries. Schedule a demo to see wearable safety data integrated with CMMS work orders and EHS compliance reporting.

Six Wearable Types Protecting Maintenance Workers
Each device monitors a specific hazard family. Deploy the right combination based on task profile and risk exposure. Start free and connect wearable data to CMMS work orders from your first shift.
Biometric Wristbands
Heat stress and fatigue
Continuous heart rate, skin temperature, and motion. Detect heat stress 15–25 minutes before symptoms appear. Kenzen, SlateSafety — $300–$600.
Smart Safety Helmets
Impact and proximity
Fall detection with GPS, proximity warnings near energized equipment, automatic man-down alerts. Guardhat, WakeCap — $400–$800.
Gas Detection Wearables
Toxic atmospheres
H2S, CO, LEL, O2 with cloud-connected readings streamed to safety officers — not just local alarms. Blackline Safety G7 — $800–$1,500.
Ergonomic Sensors
Musculoskeletal risk
Real-time posture coaching with haptic alerts on unsafe lifting. Cumulative load tracking triggers task rotation. Kinetic, StrongArm — $300–$600.
Location Tracking (RTLS)
Worker accountability
Real-time location via UWB/BLE/GPS for confined space monitoring, emergency mustering, lone worker protection, and permit zone verification.
Noise Dosimeters
Hearing conservation
Cumulative noise exposure against OSHA TWA limits integrated into hearing protection. Real-time alerts at 85 dBA threshold.
Wearable-to-CMMS Integration Pipeline
Wearable alerts without CMMS integration are seen and forgotten. Connected to OxMaint, every safety event becomes a permanent record. Book a demo to see the wearable-to-CMMS safety pipeline in action.
Stream
Continuous Monitoring
Heart rate, temperature, gas, motion, and location data every 5–30 seconds. AI compares against personalized baselines and environmental thresholds.
Alert
Tiered Risk Detection
Amber: trending toward danger, intervene in 10–15 min. Red: threshold approached, intervene now. Emergency: threshold exceeded, initiate rescue.
Record
Auto-Tag Work Orders
Every safety alert documented in the active work order — which worker, what conditions, what level, what response. EHS record created automatically.
Prevent
Scheduling Intelligence
Historical data informs future scheduling — hot tasks in morning hours, confined space rotations limited, heavy lifting distributed by cumulative load.

Your Workers Cannot Feel Danger Building. Wearables Can — and OxMaint Acts On It.
OxMaint integrates wearable biometric, environmental, and location data directly into maintenance workflows — auto-tagging work orders, generating EHS compliance records, and building the objective safety documentation that protects your workers and your organization.
Frequently Asked Questions
Do workers resist wearing biometric monitoring devices?
Programs framing wearables as "personal safety equipment" — like a hardhat — achieve 90%+ adoption within 60 days. Workers accept devices that protect them personally when data is used for safety, not surveillance.
What privacy protections apply to worker biometric data?
Can wearables work in hazardous classified areas?
Yes. Intrinsically safe devices available for Class I Div 1/2. Blackline G7 is ATEX Zone 1 certified. Kenzen and SlateSafety carry IP67+ ratings. OxMaint tracks device certification alongside worker safety data.
How accurate is wearable heat stress detection?
Wrist-based core temperature estimation achieves ±0.3°C accuracy. The 15–25 minute advance warning matters more than perfect accuracy after symptoms appear. FDA-cleared occupational monitors now available.
