Loner G7x Quad Gas



Knowledge is your superpower.
“There’s been an accident”—words that every safety manager dreads hearing. Decisions must be made in real-time, and it’s crucial to be informed. Who is involved, what happened, where is everyone and how are you going to manage the situation?

G7 is all about trust and ease of use. When the green SureSafe™ light is on, employees know their safety is in good hands. With cellular and satellite data communication, employees aren’t tethered to expensive Wi-Fi networks or unreliable Bluetooth connections.

Our technology automatically watches over each colleague and calls for help when your employees can’t. Slips, trips and falls? Check.Gas exposures? Completely covered.

G7 leverages the billions of dollars already spent on cellular terrestrial networks and the Iridium satellite network.Why spend millions on reinventing the wheel by installing Wi-Fi networks
everywhere your teams work?

G7 works right out of the box—turn it on and your team is instantly monitored.

Alarms don’t save people. – People save people.
The G7 is not just another widget. The beauty of G7 is that it connects your team to real people. We put the tools in your hands to watch over your own team, or you can leave the monitoring to Blackline with our in-house 24/7 Safety Operations Center.

Each alert is managed according to your custom emergency response protocol, from incident through to resolution. All activities are time-stamped for future reporting, including notes that are used to document the response.

Employees who face an incident experience extreme stress. Even if they can’t respond to a two-way voice call or text message, G7 brings them comfort when the blue LiveResponse™ light turns on—they know the alert was received and help is on the way.

For situations where a hazard needs to be communicated broadly to your team, those monitoring can mass-notify anyone with a G7 through voice and text messages. Confidently account for everyone’s wellbeing and whereabouts in real-time, and be equipped to act when someone needs a hand.
