Remote oilfields, isolated mines, railway corridors in the middle of nowhere—with G7x, no matter how off-the-grid a worker is, they're never out of reach.
Cellular networks were built where people live, not where your crews work. If your safety program depends on cell coverage, it stops working exactly where the risk is highest, leaving workers vulnerable.
Blackline's G7x is built for that gap.
G7x delivers the same trusted lone worker and gas detection protection as other devices in our personal gas detection lineup, with the addition of a satellite link that extends your coverage to the true "last mile".
Together, a G7x wearable safety monitor, portable G7 Bridge base station, and Blackline Live monitoring software give you end-to-end connectivity wherever the job takes you.
Note: G7x is only available in North America, Australia, New Zealand and South America (excluding Brazil)
Never Lose Connection
Harness both cellular and satellite links.
- Reliable dual-mode connectivity seamlessly switches between 4G cellular and Iridium satellite depending on the signal.
- Communicates with the G7 Bridge (required for off-grid operations) via an industrial-grade 900 MHz radio link from up to 2 kms away.
- Connect up to 5 G7x devices with a single bridge.
- Up to 18 hours of battery life keeps shifts moving safely.
- Built-in GPS pinpoints worker location quickly and accurately for fast incident response.
Connected Gas Detection
Versatile technology to stay a step ahead of risk.
-
View sensor readings on active devices in the field, from anywhere. React faster and respond safely.
-
Swap gas cartridges and customize the hazards monitored by your device to the environment.
- Get real-time alerts for high gas, over limit (OL), short-term exposure limit (STEL) and time-weighted average (TWA) to stay ahead of immediate, short and long-term risks.
One Device,
Four Configurations
G7x adapts to the job through swappable cartridges. Choose the configuration that matches the hazard, and change it as your sites change:
-
G7x Single-Gas: One target hazard, such as H₂S or CO, monitored continuously with full lone worker protection and satellite reach.
-
G7x Multi-Gas: Up to 5 gases at once from a portfolio of 20+ sensors, for sites with multiple potential gas hazards.
-
G7x Multi-Gas Pump: Adds pumped sampling for pre-entry checks and leak investigation, so remote confined space entries get the same safety coverage as any other.
- G7x Lone Worker (no gas): Operate G7x without a gas sensor if no gas hazards are present.
Every configuration includes fall and no-motion detection, SOS, GPS, and two-way text messaging as standard device functions.
20+ Swappable Gas Sensors to Choose From
Communication From Anywhere
Stay connected with two-way text messaging.
- Use a bright LCD interface directly on the device for text messaging.
- Exchange real-time messages to relay critical information, collaborate and coordinate evacuations between workers and monitoring personnel
- Send mass notifications for extreme weather and other emergencies.

Advanced Analytics
Know the status of your safety program—without the manual work.
- Manage compliance by confirming devices are worn, powered on, and up to date with bump and calibration requirements, while streamlining audits and inspections.
- Identify risk trends by using historical data to detect gas leaks early and take corrective action before incidents occur.
- Improve site visibility with ZoneAwareTM by drawing site-specific areas to see who is in each zone, spot bottlenecks and monitor movement to muster points.

"I felt safer knowing my G7x kept me connected to my team back at the office."
“Lone worker safety is a top priority for the FSA staff and volunteers. Partnering with Blackline Safety gives our organization the confidence to work safely in remote areas, stay in touch and communicate when required.”

Workers save motorists after vehicle plunges down steep embankment on isolated highway. “It was a terrible situation,” recalled Isaac. “Temperatures were dropping, the visibility was poor due to the storm and lateness of the day, and the car was trapped.”
