Description
When hazardous gases are present, there’s no room for uncertainty.
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.
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.
Features & Benefits
- Detect up to 5 gases simultaneously from 20+ sensors, with optional pump to easily switch between pre-entry and continuous 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-optimized, industrial design with a bright display and quick-access flashlight for demanding work environments.
- 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.
- Emergency Voice with a real person checking in when an alert is triggered and sending immediate help if needed.
- 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.
- Automated reporting that saves you time, shows if safety devices are being worn, turned on, and calibrated for easier compliance management.
- Historical trend data on gas leaks and exposures supports incident investigation, root cause analysis, and continuous improvement of gas safety practices.
- ZoneAware™ to draw site-specific areas and understand who is in each zone, spot bottlenecks, and monitor movement to muster points.

Frequently Asked Questions
What is the Blackline Safety G8 used for?
The G8 is a portable gas detector used to monitor hazardous atmospheres and help protect workers by providing alarms for gas exposure. It can also support connected safety workflows depending on configuration.
Which gases can the G8 monitor?
G8 monitoring capability depends on the sensor configuration. Common industrial setups can include oxygen (O₂), combustible gases (LEL), and toxic gases such as CO and H₂S, with other options depending on requirements.
Is the G8 a single-gas or multi-gas detector?
G8 is commonly configured as a portable multi-gas detector, with the exact sensor suite selected based on hazards, industry, and job role.
Does the G8 support connected or cloud-based monitoring?
Yes. G8 can support connected safety features such as status visibility, alerts, and compliance reporting through Blackline’s software platform, depending on your service plan and deployment setup.
Can the G8 be used for confined space entry operations?
G8 can support confined space operations when configured for the hazards present and used within your confined space program. Confirm whether pumped sampling or accessories are required for your entry procedures.
What types of alarms does the G8 provide?
Portable gas detectors typically provide audible, visual, and vibration alarms. Alarm set points and behavior depend on configuration and site safety requirements.
How are bump tests and calibrations handled for the G8?
Bump testing and calibration may be performed using docking/calibration solutions and your SOPs. Safeware can help recommend a testing workflow and documentation process.
Is the G8 certified for hazardous locations?
Certifications vary by model and configuration. Confirm required Class/Division or ATEX/IECEx needs during selection to ensure the correct approvals.
How do I choose the right sensor configuration for my team?
Start with your hazards (LEL, O₂, CO, H₂S, or other toxics), exposure limits, and work environment (confined space, industrial plant, utilities). Safeware can help map requirements to an appropriate G8 configuration.
Can the G8 support lone worker safety programs?
Yes. Connected devices can support worker monitoring and escalation workflows for lone or remote workers depending on the configured safety platform and policies.
