Understanding Real-Time Location Systems for Employee Tracking Solutions

Real-time indoor employee location tracking systems use various technologies to determine where employees are inside a building or campus. Such systems usually rely on a network of sensors, readers, or tags that communicate with a central server.
The central server collects location information from the sensors. It then provides real-time visibility into the location of employees. This information can help for a number of reasons, including safety, security, and improvement in how the organization works. For instance, a company might use real-time indoor employee location tracking to rapidly locate a missing worker, monitor employees during an emergency, or make its operations more efficient.

Top Use Cases of RTLS-Based Employee Location Monitoring Systems

Real-Time Worker Location Tracking and Alerts

Use case: RTLS tracks an employee’s location throughout all facilities, so the personnel can be within a proper safety zone, and the authorities will intervene rapidly in dangerous situations if required.

Example: At a petrochemical plant, RTLS monitors workers conducting inspections near high-pressure pipelines. If a worker enters a restricted zone or stays longer than safe exposure times, the system alerts both the worker and their supervisor. This ensures compliance with OSHA’s Process Safety Management (PSM) standards, which require employers to mitigate risks from hazardous chemicals.

Collision Avoidance and Proximity Detection

Use Case: RTLS prevents accidents by maintaining safe distances between workers and mobile equipment such as forklifts or autonomous vehicles.

Example: In an automotive parts warehouse, RTLS integrates with forklifts to automatically slow their movement when workers are detected within five feet. This system aligns with ANSI/ITSDF B56.1 standards, which mandate clear visibility and safe pedestrian pathways during industrial truck operations.

Emergency Evacuation and Incident Management

Use Case: RTLS will ensure all personnel are accounted for during emergencies by tracking their movement to assigned zones of evacuation.

Example: During a fire drill at an automotive manufacturing plant, RTLS tracked the movements of over 2,000 employees, identifying any who had not reached safe zones. This real-time data enabled safety officers to quickly direct resources to those in need and ensured compliance with NFPA 101 (Life Safety Code), which requires comprehensive occupant accountability during emergencies.

Access Control for Hazardous Areas

Use Case: RTLS limits access to hazardous areas, ensuring that only qualified and authorized personnel have access.

Example: In a pharmaceutical manufacturing facility, RTLS will ensure that only trained employees with valid certifications are allowed into cleanrooms. In case an untrained employee tries to gain access, the system will lock access and alert the supervisors. This will help in compliance with ISO 45001:2018 standards, which mandates organizations to limit risks in high-hazard areas.

Worker Fatigue and Health Monitoring

Use Case: RTLS monitors worker activity levels to detect signs of fatigue and prevent accidents caused by overexertion.

Example: At a steel manufacturing facility, RTLS tracks movement patterns to note when workers are slowing down or exhibiting signs of fatigue due to long shifts. Supervisors are alerted to assign breaks or rotate tasks, based on OSHA’s Ergonomics Program Management Guidelines, which stress reducing injuries associated with repetitive or prolonged work.

Hazard Zone Alerts and Dynamic Geofencing

Use Case: RTLS creates virtual boundaries around high-risk areas and alerts workers who breach them without proper personal protective equipment (PPE).

Example: At a metal fabrication shop, RTLS geofences around welding zones trigger alerts if workers enter without flame-resistant clothing. Supervisors are also notified, ensuring compliance with OSHA 1910.132, which mandates the use of PPE in hazardous environments.

Proactive Safety Training and Compliance Verification

Use Case: RTLS checks the training and credentials of workers before accessing equipment or high-risk areas.

Example: In an electronics assembly plant, RTLS checks training credentials in real time before workers can operate precision tools. If a worker’s certification is expired or missing, the system denies access and notifies the training department. This process ensures compliance with OSHA 1910.147 (Control of Hazardous Energy), which requires proper training for employees operating potentially dangerous machinery.

Choosing the Right RTLS Technology for Employee Safety Tracking

Choosing the right RTLS technology is fundamental to building a reliable safety system. From infrastructure-heavy systems like UWB and BLE to simpler ranging technologies like TWR and advanced vision-based solutions, each comes with unique benefits and hidden limitations.
The complexity of factors—such as precision needs, environmental challenges, scalability, and budget—makes the decision even more critical and often confusing.

Infrastructure-Based RTLS (UWB, BLE)

Infrastructure-based RTLS delivers real-time, high-precision tracking of workers, ensuring safety in complex manufacturing facilities. Acting like an indoor GPS, these systems provide location updates with sub-meter accuracy.

Applications in Safety:
Prevent accidents by tracking proximity between workers and forklifts.
Track employees in hazardous zones to enforce time restrictions.
Assist in emergency evacuations by providing real-time worker

Advantages:
High Precision: Tracks workers with sub-meter accuracy, ideal for critical safety zones.
Versatility: Simultaneously monitors workers, equipment, and access points.
Safety Insights: Generates heatmaps of hazardous activity areas for proactive risk management.

Considerations:
Initial setup costs can be significant, but leveraging RTLS across multiple safety and operational use cases improves the return on investment.

Non-Infrastructure Ranging Systems (TWR)

Non-infrastructure RTLS, such as Two-Way Ranging (TWR) systems, offer simple and cost-effective solutions for smaller facilities or specific safety zones.

Applications in Safety:
Tracking workers in open or remote areas to ensure their well-being.
Alerting supervisors if workers enter restricted zones without authorization.

Advantages:
Low Setup Costs: Ideal for smaller operations or limited budgets.
Ease of Deployment: Effective in open environments with minimal interference.

Considerations:
TWR systems may not provide the precision required in busy or metal-heavy environments. For more complex safety needs, infrastructure-based RTLS systems are preferred.

Vision-Based Tracking (Camera or LIDAR)

Vision-based RTLS utilizes AI-equipped cameras or LIDAR to visually monitor the worker’s movement and implement safety standards. It is the most efficient in situations where precise visual proof of compliance is mandatory.

Applications in Safety:
Detecting workers approaching hazardous equipment without proper PPE.
Monitoring compliance with safety rules, such as tool usage or workspace protocols.

Advantages:
Real-Time Alerts: Quickly detects and responds to safety violations.
Enhanced Compliance: Provides visual verification for audits and inspections.

Considerations:
Vision-based systems are affected by environmental factors like lighting, dust, or obstructions and require high computing power. Cloud-based AI can enhance performance.

Indoor-Outdoor Hybrid Tracking

Hybrid RTLS systems combine UWB or BLE for precise indoor tracking with GPS or RTK for outdoor environments, providing seamless worker visibility across diverse areas.

Applications in Safety:
Ensuring worker safety during transitions between indoor and outdoor operations.
Monitoring compliance across assembly lines, staging areas, and logistics zones.

Advantages:
Comprehensive Coverage: Tracks workers effectively in both indoor and outdoor spaces.
Cost-Efficient Options: Combines precise indoor tracking with affordable outdoor solutions like LoRaWAN.

Considerations:
Outdoor tracking may lack the precision of indoor systems. RTK offers higher accuracy but can increase costs.
