As industrial sites become ever more connected through digitisation, gas detection systems have likewise evolved to support them. Here, MSA Safety explains how connected gas detection systems can transform health and safety management through shared alerts.
In recent years, innovation in gas detection technology has accelerated. Advances in connectivity and digital integration are enabling safety systems to do more than simply detect hazards. Connected devices can now share information, provide real-time visibility of conditions and support faster, more coordinated responses when incidents occur.
This shift towards connected safety solutions is helping organisations move beyond isolated monitoring and towards more integrated approaches to risk management.
One example of this evolution is the growing use of connected gas detection systems such as MSA Safety’s ALTAIR io™ 4 Connected Gas Detector, which integrates with the MSA Grid platform. Equipped with built-in CAT-M LTE cellular connectivity, the ALTAIR io™ 4 can transmit data directly to the cloud, allowing safety teams to monitor alerts, device activity and safety data in real time.
Through the Grid platform, connected devices can also share alarm notifications through features such as the Shared Alerts System. Rather than limiting alarms to the individual worker carrying the device, Shared Alerts allows notifications to be distributed to nearby colleagues. If a detector such as the ALTAIR io™ 4 triggers an alarm, workers nearby can receive an alert directly on their own device.
In many traditional gas detection systems, alarms are largely localised. When a device detects dangerous gas levels, the alert is typically limited to the individual wearing the detector, meaning others nearby may not be aware of the situation unless informed separately.
By sharing notifications across connected detectors, workers can be informed immediately when a colleague nearby experiences a potential safety issue, enabling faster awareness and response.
How shared alerts work in practice
When organisations upgrade from non-connected gas detection systems to connected solutions such as ALTAIR io™ 4 detectors connected to MSA Grid, devices can communicate through the platform and share alerts across the workforce.
The system can be configured in different ways depending on the operational environment. Alerts can be proximity-based, meaning workers within a defined distance receive a notification when an alarm is triggered. Alternatively, alerts can be assigned using location or organisational labels so that workers operating in the same building, floor, department or operational zone receive the alert.
This flexibility allows safety teams to configure alert distribution in ways that reflect how their facilities operate.
Workers can receive notifications relating to several different types of alarms:
Gas alarm – occurs when a device such as the ALTAIR io™ 4 detects dangerously high levels of gas, including substances such as hydrogen sulphide (H₂S) or carbon monoxide (CO), or when a worker reaches an exposure limit. Through the Grid platform, these alerts can be shared with nearby workers so they are aware of the hazard and can take appropriate action.
Motion alarm – may activate if a worker remains motionless for an extended period, indicating a potential emergency such as a collapse or medical incident. Shared alerts mean colleagues nearby can receive a notification quickly and investigate the situation.
Worker emergency alarm – can be triggered manually if a worker needs assistance. Once activated, the alarm can be communicated through connected detectors, helping make sure that support can reach the worker as quickly as possible.
Improving awareness and response
The ability to share alerts through connected gas detection systems offers several advantages in workplace safety management.
One key benefit is improved situational awareness. When alerts generated by devices such as the ALTAIR io™ 4 are shared across connected detectors through the Grid platform, workers nearby gain immediate visibility of potential hazards.
Faster communication can also support more effective emergency responses. Rather than relying on manual communication processes, alerts can be distributed automatically, allowing workers to take action without delay. In situations where gas exposure or worker distress is involved, this speed can be critical.
For safety managers, the combination of connected detectors and the Grid platform also provides greater oversight of site activity. Real-time alarm data can help safety teams understand what is happening across a facility and coordinate responses when needed.
Supporting a connected safety culture
As digital technologies continue to reshape industrial workplaces, connected safety solutions are becoming an important part of modern risk management strategies.
Systems that link devices such as the ALTAIR io™ 4 with cloud platforms like MSA Grid demonstrate how gas detection technology is evolving beyond standalone monitoring tools. By enabling devices, workers and safety managers to share information more effectively, these systems help organisations respond more quickly to potential hazards.
Shared alerts are one example of how connectivity can strengthen existing safety practices. By ensuring critical information reaches workers when needed, connected gas detection solutions can help organisations build a more aware, responsive and collaborative safety culture.
