When hazardous gases are present, there's no room for uncertainty.

The G8 delivers advanced gas detection in a rugged, intrinsically safe device designed to perform in the most demanding environments.

With swappable cartridges and coverage for virtually any gas your team may encounter, G8 provides reliable protection without slowing work down.

And it does so much more than detect gases.

Blackline Safety's G8 combines real-time alerts, built-in radio communication, and direct-to-cloud data to keep workers safe while improving visibility, response, and productivity across every site.

Connected Gas Detection

Protect your people from gas exposures with a portable detector that’s built for how they work:

• Detect up to 5 gases simultaneously from 20+ sensors, with optional pump to easily switch between pre-entry and continuous gas monitoring.
• Advanced 4G LTE cellular connectivity with auto-switching between major carriers for the best coverage. 
• Swappable cartridges to adapt to any situation (lone worker, single-gas, multi-gas, or multi-gas pump).
• Sensor readings to monitor the latest gas data, spot elevated readings sooner and act faster. 
• Configurable alert thresholds to align with site policies, regulatory requirements, and job-specific risk profiles.
• Field-optimised, industrial design with a bright display and quick-access flashlight for demanding work environments.

G7 Lone Worker Cartridge options

Standard Cartridge (lone worker)	Single-gas Cartridge	Multi-gas Cartridge	Multi-gas pump Cartridge
A G7 wearable device equipped with a standard (no gas) cartridge functions as a personal safety and lone worker device, monitoring the wellbeing of workers and alerting live monitoring personnel in the event of an emergency, fall or health event.	A single-gas cartridge providing targeted gas detection for environments with specific or known hazards. The G7 wearables are compatible with the single-gas cartridge.	Compatible with G7 and EXO, the multi-gas diffusion cartridge accommodates two to four sensors and monitors for up to five gases when fitted with a dual-toxic COSH sensor. This cartridge supports all sensors in Blackline Safety's comprehensive portfolio.	Multi-gas pump cartridge that can monitor for up to five gases (when fitted with a COSH sensor) It features an internal pump. Ideal for confined space entry and leak check applications, the pump can be turned on and off on the go using configuration modes to  temporarily change their  G7's functionality to suit the scenario.

Monitoring and Awareness

Always know where your people are, what they’re facing, and when something changes—so you can respond quickly, confidently, and with the right information.

• Dual-band GPS/GNSS to pinpoint worker location, ensure quick incident response, and to show when and where every alarm, event and near-miss takes place.
• Real-time alerts for time-weighted average (TWA), short-term exposure limit (STEL), high/low gas levels, bump tests, calibrations, falls, no-motion, missed check-ins,  proximity-based events, and silent and emergency SOS.
• Direct-to-cloud data streaming from the field to Blackline Live for alert management and worksite visibility.
• 24/7 live monitoring through your own safety control center, Blackline’s in-house Safety Operations Center (SOC), or our global Alarm Receiving Center (ARC) partners.

Human-to-Human Communication

Three ways to communicate in one device means your people can get help quickly and work together better with: 

• Emergency Voice with a real person checking in when an alert is triggered and sending immediate help if needed.*
  *connects to your own control room or Blackline’s 24/7 live monitoring service
• Push-to-Talk works just like a two-way radio, using a dedicated button for clear audio and optional remote speaker mic (RSM) rivaling any industrial radio — so teams can coordinate quickly across sites.
• Text messaging for fast mass notifications, like evacuations or extreme weather events, and for workers to send custom or pre-set messages to monitoring personnel when help is needed.
