Connected Safety
The G8 portable gas detector and lone worker devise is the most connected safety wearable ever made - it ensures that no team member is ever truly alone and helping you build a strong safety culture that moves beyond compliance.
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.
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.
G8 is Blackline Safety's personal safety monitoring device and is available as a standard, single-gas, or multi-gas detector. G8 continuously measures gas concentrations in the ambient environment and activates notifications when concentrations exceed setpoints, allowing operators to respond quickly and safely to changes in their environment. G8 has integrated 4G cellular networks to communicate with Blackline Live and is available anywhere in the world.
