Blackline Safety Wireless Gas Detection Technology 24/7 - Single Gas Detector
The only gas detector with a loudspeaker designed for noisy environments. Worker movement can be monitored in real time 24/7 with Google Maps functionality.


Blackline Safety is not just a personal gas detector. It is the only device in the world equipped with a speakerphone designed for noisy conditions. The alarm includes call and text message functionality.
Employee movement can be tracked in real-time 24/7 using Google Maps functionality, for example, from a control room. The technology automatically monitors the worker and calls for help when the worker cannot do it themselves, e.g., after a fall or gas exposure – similarly, the worker can contact the control room.
Every second counts, and no one is forgotten
- When an accident occurs, the clock starts — and it doesn’t stop until help arrives. G7c allows you to manage time. If a worker falls from a ladder, dangerous weather is approaching, or there has been an explosion or gas leak, every inactive minute can be fatal.
- Does your production facility need evacuation? Start a full-area or partial evacuation in seconds. The tracking system allows you to send a text message or recorded message to target workers and provide instructions for gathering points.
- Gain peace of mind knowing that each person’s location is visible on an interactive map, including floor plans. Get your team to safety and track everyone’s location. No one is forgotten.
