G7 Multi-Gas

Real-time protection for today, a scalable platform for tomorrow.

G7 Wearables Video

Get peace of mind with the wearable G7 multi-gas detector that harnesses connectivity, paired with data insights, for fast incident response to better protect your people from potential hazards and improve safety processes and compliance over the long term.

With out-of-the-box deployment, configurability for a variety of job functions and situations, quick assign to workers, plus monitoring for up to five gases, G7 multi-gas detector can reduce the cost and complexity of fleet management.
With G7 multi-gas detector you get:

Broad Gas Sensor Portfolio

Detection for up to five gases, with a portfolio of up to 20 gases to choose from.  

If your people change sites frequently or you notice the environmental hazards of your facility are changing, G7 gas sensors can be updated to address evolving needs. 

Simply swap out your existing multi-gas sensor cartridge for a new one with sensors suited to the environment. They’re even hot-swappable, so they can be changed on the job or while in transit to a new incident site.


Real-Time Visibility

Get connected to where your people are whenever and wherever and know exactly when and where incidents occur.

  • Built-in cellular connectivity, with optional satellite and portable bridge, for remote or hard-to access locations
  • Location technology including geo-stamped alert status from any Internet-connected device
  • Direct-to-cloud data streaming to Blackline Live software platform for real-time information at your fingertips

G7 multi-gas connects in seconds without the need for any expensive, intrinsically safe smart phones, apps, hidden subscription costs or added infrastructure.

Immediate Emergency Response

Your cloud-connected G7 multi-gas detector has built-in layers of communication to send an alert during an incident. When paired with 24/7 live monitoring, it’s the critical lifeline to your people for the help they need during an emergency, health event, dangerous situation and more.

Layers of communication
  • Manual - patented SOS latch so your people can send an emergency call for help
  • Automatic - automated no motion and fall detection let your G7 send an alert when your people can’t
  • Time-based - identifies when a team member misses a scheduled check-in 

Stay connected with the safety of each worker in any situation through alerts and notifications.

Add-on features
  • Two-way voice communication so first responders can connect directly with workers during an emergency
  • Customized mass notification text messages means you can quickly and efficiently communicate with specific groups or entire sites
  • Push-to-Talk (using the device like a walkie-talkie) for easy communication between teams

Communication options meet your diverse safety needs, keep your workers connected and ensure your people only need to wear one device to get the protection and peace of mind they need.
Help is always on the line
  • Optional professional 24/7 live monitoring through Blackline Safety’s in-house Safety Operations Center (SOC) or global Alarm Receiving Center (ARC) partners
  • Agents are five diamond certified, meaning they are empowered to escalate responses to dispatch local emergency services to the employee’s exact location
  • Fast response from alert receipt through to resolution, with responses executed according to your custom emergency response protocol
Alerts received in Blackline Live in <2 seconds
Alerts responded to by 24/7 live monitoring services in <60 seconds
Emergency services are dispatched if required
Advanced evacuation management
  • Customized mass notification text messages or Push-To-Talk to individual G7 devices quickly lets workers, specific teams or entire sites know they need to evacuate and can direct them to muster points or other safe locations
  • Monitor workers location in real-time throughout evacuations or drills, giving you the ability to see the precise location of any missing workers
  • Eliminate manual headcounts with location technology to visualize workers' safe arrival at muster points and account for the safety of everyone

Harness data from evacuation drills to increase efficiency and improve preparedness for real emergencies.

“Data collection and analysis is the present and future of the industrial sector. With the data we’re able to collect, track and analyse, we can respond and adapt quickly if there is a risk of gas exposure, and also look back to take steps to mitigate that risk in the future. Data is a driving force in keeping our people safe and supporting our commitment to the environment.”

– Mark Silvester, CEO - Enovert


Compliance Management

No more waiting to manually collect usage data and gas reading information, and you won’t have to rely on historical data to know if your fleet is compliant and your teams are safe.

  • Verification that devices are being worn, turned on and calibrated and bump tested to your standard operating procedures 
  • Every bump test, calibration, gas exposure and usage session are automatically recorded for hassle-free reporting.
  • Time, place, and device are identified in the reporting of alarms, high gas residues and other types of exposure
  • Attain insight into gas detection compliance status in real-time and act on non-compliance to better protect workers 
  • Interactive reports make reporting cycles accurate and effortless

Blackline Analytics Essentials deliver a complete view of your fleet's operations. Easily identify how equipment is being used, where hazards are being encountered and even determine which devices are performing well and which can be leveraged better.


Introducing Alertlink

Improve safety with immediate proximity-based warning alerts for urgent events, ensuring swift action and enhanced protection for every worker.



Powerful Analytics for Data-Driven Safety

Data from connected devices leads to quicker action and better, more informed decisions.

  • Identify patterns in when and where incidents or gas leaks occur and take action to mitigate.
  • Gain insights into how, when and where devices are used to understand worker behaviors, improve scheduling and amplify productivity.

Optional Accessories

  • G7 Bridge  - portable base station that provides a critical satellite uplink to address the challenges of poor connectivity and spotty communications for teams working in remote locations outside of cellular coverage.
  • G7 Dock – calibrate, bump test and charge your device seamlessly without any of the complicated ethernet or Wi-Fi connection requirements of other systems.
  • G7 Power Pack — need to keep your G7 multi-gas detector running around the clock? The intrinsically safe, hot-swappable G7 PowerPack supports long-term intensive projects like shutdowns and turnarounds.
  • Location Beacon – augment location transmissions where GPS alone may not be sufficient. 

Did You Know?

G7’s automated, over-the-air firmware and configuration updates can free you up, helping you save hundreds of hours (and thousands of dollars) by eliminating the need for manual device data collections.


All of our G7 devices integrate seamlessly within the rest of our connected safety ecosystem, delivering an array of industry-leading tools and services to help keep your teams safe and amplify your productivity.
