Identify risks continuously, not just during periodic inspections.
Traditional hazard identification relies on periodic manual inspections: a safety officer walks the floor, completes a JSA or JHA checklist, and files a report. By the next inspection cycle, conditions have changed. PETRAN replaces periodic assessment with continuous real-time hazard monitoring: every connected sensor, wearable, and camera is continuously detecting and quantifying the hazards present in the working environment - gas concentrations, thermal conditions, proximity to vehicles, zone occupancy, and environmental parameters - 24 hours a day, across every shift.
Prevent incidents before they escalate — reducing both direct losses and the hidden operational costs that follow.
Automate permits, logs, and audit trails so compliance is always documented, searchable, and inspection-ready.
Use live RTLS-based accountability to accelerate evacuations, locate missing personnel instantly, and keep emergency response under control.
Give supervisors and frontline teams real-time safety intelligence that drives proactive action and strengthens trust in workplace safety.
Hybrid RTLS combining UWB (10–30 cm accuracy) for indoor precision positioning, GPS/RTK for outdoor tracking, and BLE for broad-area zone sensing. Continuous motion/no-motion monitoring: if a worker stops moving for longer than the configured no-movement threshold, PETRAN triggers a man-down alert automatically. Zone entry and exit events are logged with worker identity, timestamp, and duration for permit compliance verification.

WBGT (Wet Bulb Globe Temperature) proxy monitoring combined with activity level adjustment to calculate each worker’s real-time heat stress exposure. Alert thresholds are configurable per activity type (sedentary, moderate, heavy physical work) in line with ACGIH TLV® guidelines. Cumulative exposure tracking detects workers approaching dangerous heat stress accumulation before symptoms develop.

Real-time monitoring of O₂ (oxygen deficiency/enrichment), H₂S (hydrogen sulphide), CO (carbon monoxide), LEL (lower explosive limit percentage), and VOCs (volatile organic compounds) from portable personal gas detectors and fixed-area monitoring units. TWA (Time Weighted Average) and STEL (Short-Term Exposure Limit) compliance tracking per OSHA PELs and NIOSH RELs. Instant gas alarm with automatic PTW lockout.

IMU (Inertial Measurement Unit) based detection in wearable devices identifies fall events through acceleration signature analysis: rapid vertical deceleration, impact force measurement, and post-fall no-movement detection. Multi-stage alert escalation: immediate wearable vibration + audio alert; if worker does not acknowledge within the configured window, supervisor is notified; if unacknowledged within a second window, emergency response is activated.

Worker-to-vehicle proximity monitoring using UWB or BLE tags on both the worker and the vehicle - triggering alerts on wearable devices and vehicle driver displays when workers enter the proximity exclusion zone. Energized zone monitoring prevents workers from entering areas with live electrical equipment without authorisation. Restricted area geofencing with configurable entry/exit alerts and automatic PTW validation.

Fixed-area environmental sensors monitor temperature, relative humidity, noise exposure (dB), light intensity (lux), and vibration levels continuously. Noise dosimetry tracking calculates cumulative hearing exposure against OSHA PEL (90 dBA TWA) and action level (85 dBA TWA). High-humidity or extreme-temperature zone monitoring triggers alerts before conditions reach hazardous levels for workers in the area.

Continuous monitoring of wearable device battery charge level (alert when below configurable threshold), sensor heartbeat signal (alert when sensor stops reporting), calibration status (alert when gas sensor calibration is due or overdue), and GPS/BLE signal quality. Device health visibility prevents the most common failure mode in RTLS deployments: undetected device failure leaving workers without protection without the safety team’s knowledge.

PETRAN’s Hybrid RTLS combines UWB, GPS/RTK, and BLE to deliver continuous worker location tracking. UWB enables high-precision indoor positioning for safety-critical zones, GPS/RTK supports outdoor tracking, and BLE provides cost-effective zone-level coverage.
Industrial sites use mixed safety devices from multiple vendors. PETRAN unifies this ecosystem by ingesting and normalising data across BLE, UWB, RFID, LoRaWAN, LTE-M/5G, Modbus, and OPC-UA into a single, consistent data pipeline.
Safety events need instant response. PETRAN’s Edge AI runs fall detection, no-motion alerts, proximity risk scoring, and gas threshold checks directly on-site, enabling sub-second alerts without relying on cloud latency.
PETRAN’s rule engine enforces safety procedures digitally through geofences, time-in-zone limits, lone-worker check-ins, and real-time permit validation-triggering alerts and escalations automatically when safety rules are breached.
PETRAN’s SOS system enables rapid emergency response with instant alerts, precise worker location, supervisor notifications, acknowledgement confirmation, guided response actions, and real-time tracking to improve outcomes in critical situations.
PETRAN’s Command Centre dashboard provides a unified safety view with live worker locations, gas alerts, permit status, device health, and evacuation tracking-giving managers real-time visibility of workers, hazards, and operations in one place.
PETRAN integrates with CMMS/EAM, EHS, HRIS, and messaging platforms to sync safety data across systems. It enables bidirectional flow-pushing safety events to enterprise tools and validating worker access using training and certification data.
Passive/active RFID for access control, tool tracking, and permit validation at zone gates. Low cost per tag, long read range for gate-based access systems. Suitable for non-precision zone-level tracking.
