G7 Single Gas

G7 Single Gas

The Blackline Safety G7c wirelessly connects your team to real people. We put the tools in your hands to watch over your own team, or you can leave the monitoring to our in-house 24/7 Safety Operations Center.

Wireless connectivity ensures that each G7c is remotely configurable and firmware updates are automatic. G7c supports three cartridge types that provide a choice of gas detection options. Everything is completely customizable to meet the needs of every industry, application and scenario. Employees who face an incident are under incredible pressure. Even if they can’t respond to a two-way voice call or text message, G7c brings comfort when its blue LiveResponse™ light turns on—the alert was received and help is on the way.

Each alert is managed according to your custom and documented emergency response protocol. From incident through to resolution, all activities are time-stamped for future reporting, including notes that are used to document the response.

For situations where a threat needs to be communicated broadly to your team, monitoring personnel can mass-notify your choice of personnel at one or more sites. Confidently account for everyone’s wellbeing and whereabouts in real-time, and be equipped to act when someone needs a hand.
