G7 Multigas Detector


⇒ Gain real-time visibility of workers’ safety, including their location-stamped alert status, from any internet-connected device
⇒ Identify how, when and where G7 multi-gas detectors are being used to understand worker behavior and optimize device utilization
⇒ Attain insight into all incidents and gas detection compliance status in real time knowing when and where they occurred
⇒ Deploy instant responses following your customized emergency response protocol using Blackline’s professional 24/7 live monitoring services
⇒ Safely and efficiently initiate evacuations for specific groups or entire sites with customized mass notification text messages to individuals’ G7 devices or using push-to-talk functionality, directing them to specific muster points
⇒ Save hundreds of thousands of dollars with evacuation management tools and post-event data analyses by optimizing drills
⇒ Leverage data analytics to predict future incident risks and plan mitigations
⇒ Save thousands of dollars with automated, over-the-air firmware and configuration updates, eliminating the need for manual device and data collection
⇒ Get connected in seconds via the device’s integrated cellular connectivity without any expensive intrinsically safe smartphones, apps, hidden subscription costs or added infrastructure
⇒ Achieve connectivity in even the most remote locations and in areas where cellular networks are overwhelmed with optional satellite functionality
⇒ Ensure maximum worker protection with automated safety incident and health event monitoring, including no-motion and fall detection
