Maintain visibility over workers and contractors while connecting tracking data with SOS, alarms, and evacuation support. This helps teams account for personnel quickly and coordinate responses when incidents occur.   #### Active Tracking Wearable Tags - Identifies each worker automatically throughout the site. Vehicle Occupancy Tracking - Detects multiple tagged workers travelling inside vehicles. Zone Monitoring - Helps teams see when workers enter, leave, or remain in defined areas. #### SOS Tunnel Box A highly visible emergency station that lets tunnel workers quickly trigger alarms and communicate with the control room during an incident.

Monitor hazardous gases, air quality, and changing environmental conditions across tunnels and enclosed work areas. Real-time sensing and automated alerts help teams respond faster when conditions become unsafe.   ![rilevazione-gas-infografica-rka397ym9edr4wtfb9hkvaib6pzno0yj5z7cxyctog](https://www.3fbdistribution.com/hubfs/rilevazione-gas-infografica-rka397ym9edr4wtfb9hkvaib6pzno0yj5z7cxyctog.jpg "rilevazione-gas-infografica-rka397ym9edr4wtfb9hkvaib6pzno0yj5z7cxyctog") #### Attributes: Continuous Environmental Monitoring - Sensors track gas levels, oxygen, temperature, and other critical conditions throughout the site. Two-Stage Alert System - A first threshold triggers a pre-alarm, while a second, higher-risk threshold activates a full alarm and escalates the warning to operators and the control room. Centralized Monitoring & Response - Environmental readings and alarms are sent to a central platform so teams can quickly assess conditions and coordinate the appropriate response. [Request Solution Brochure](https://www.3fbdistribution.com/contact-3fb?hsLang=en) ### Access Control & Site Security. Manage entry into restricted or high-risk areas while improving oversight of workers, contractors, visitors, and vehicles. Access systems can integrate with identification, surveillance, and alarm technologies for stronger site control. #### Attributes: Multi-Technology Access Control - Uses badges, QR codes, mobile credentials, license-plate recognition, and optional biometric systems to identify personnel, contractors, visitors, and vehicles. Automated Authorization Management - Controls access based on factors such as role, schedule, training, documentation, and permitted work areas, helping prevent unauthorized entry into high-risk zones. Integrated Site Security - Connects access records with personnel tracking, surveillance, and event data to give teams greater visibility over who is on site and activity around critical areas. More than simply a badge-management system, AME supports physical access infrastructure such as gates, barriers, turnstiles, and readers alongside the digital authorization platform.

Keep workers, equipment, and control rooms connected through integrated network, radio, and mobile communication systems. Centralized monitoring brings key safety, access, alarm, and operational information into one coordinated view. ![mobile-communication-infografica-rka37nkavc8jsb3cgl3ypoqnjlpmu6qmy8285cog1s](https://www.3fbdistribution.com/hubfs/mobile-communication-infografica-rka37nkavc8jsb3cgl3ypoqnjlpmu6qmy8285cog1s.jpg "mobile-communication-infografica-rka37nkavc8jsb3cgl3ypoqnjlpmu6qmy8285cog1s") #### Attributes: Tunnel Network Infrastructure - Fiber-optic, industrial Wi-Fi, and routing systems provide the reliable data connection needed to keep safety technologies operating across large or underground sites. Mobile & Voice Communication- GSM, UHF radio, and fiber-based telephone systems help field teams maintain reliable communication with one another and the control room throughout the tunnel. **Centralized Control Room** - Brings tracking, alarms, environmental monitoring, access control, communications, and other site information into one operational view for faster coordination and response.
