Durham, UK-based Northumbrian Water Group (NWG) has announced that it has selected global connected safety technology pioneer Blackline Safety Corp. to help uncover safety hazards and protect lone workers at two of its water treatment sites.
The water company – which provides clean water and wastewater treatment services to nearly five million people across northeast and southeast England – is the eighth of the UK’s 12 water companies to choose Blackline’s safety devices.

The technology includes Blackline’s pioneering cloud-connected G7c personal gas wearable and EXO area monitor, enabling NWG to consolidate gas detection, communication, and lone worker connectivity into a single device.
NWG’s decision to turn to Blackline was spurred by the risks inherent in its operations, including exposure to gases, hazardous or contaminated water, explosions from hot work or combustible gas, confined space entry and lone work.
Robust and versatile safety solution
An explosion at a different company’s treatment plant within the wider water industry, where four workers died, also prompted the company to invest in a robust and versatile safety solution.
“Feedback we were getting from the team on-site was that they just want to do their jobs but had too many devices, apps and things to think about, and anything we could do to simplify the process would be beneficial for everyone,” said Dan Woodward, Process Safety Business Partner at NWG.
Mobile phones to maintain communication
Workers had walkie-talkies, adding both complexity and cost with an additional device to manage
Woodward added: “We were looking for a solution that addressed the need for gas detection and lone working features within one device and could significantly improve our safety and operational efficiency.”
While NWG had in the past used portable gas monitors to detect hazardous gases, and mobile phones to maintain communication with workers, these devices had limitations – from cross-sensitivity issues that led to missed or faulty detection, operational downtime due to needing to send the devices off-site for calibrations, and mobile phones posing an ignition hazard in biogas-rich environments. Workers also had walkie-talkies, adding both complexity and cost with an additional device to manage.
Remotely monitor gas levels
Blackline’s all-in-one solution has significantly simplified the process for the water company. The EXO monitors, for example, remotely monitor gas levels in known high-risk areas. The G7 wearables enable multi-gas detection and reduce downtime as they can be calibrated on site.
The personal devices’ integrated capabilities – such as remote monitoring and instant worker location identification – significantly boost lone worker safety, and push-to-talk capabilities (using the device like a walkie-talkie) means workers now have reliable communication while only needing to carry one device.
Benefits of Blackline’s solution
NWG was able to respond immediately by issuing a ‘stop work’ order, notifying workers
NWG is already seeing the benefits of Blackline’s solution. With the help of EXO, they discovered a previously unidentified hazardous area on-site, reaching 75% of the explosive limit during operations.
Upon receiving a high gas alert from EXO, NWG was able to respond immediately by issuing a ‘stop work’ order, notifying workers and safely evacuating the area. Preventative measures were then able to be implemented.
Integrated into daily operations
NWG also noted that the Blackline devices have seamlessly integrated into their daily operations, staying connected even in underground environments where cellular signal strength can be problematic. Analytics reports from collected device data highlight areas of concern, such as previously unknown high-gas exposure zones.
Northumbrian Water will join Blackline Safety at the Health & Safety Event in Birmingham, UK, on April 9, 2025, to share insights on their decision to enhance worker safety through connected technology.
