ATEX & hazardous areas


Point Detectors: These are fixed devices that can detect methane levels in specific locations where they are installed. They provide real-time readings and are often used in areas with known risks. Infrared and catalytic bead sensors are common detection methods. Recommended MSA Safety gas detectors: ULTIMA X5000, General Monitors® S5000, PrimaX IR


Open Path Detectors: These devices use infrared technology to detect methane along an open path between a transmitter and a receiver. Changes in the infrared light absorption indicate the presence of methane. Recommended MSA Safety gas detectors: Senscient ELDS, IR5500


Acoustic Detectors: Acoustic (ultrasonic) sensors can detect the sound of gas escaping from leaks. This method is especially useful for identifying leaks in pressurised systems and can complement other detection methods. Recommended MSA Safety gas detectors: Observeri Ultrasonic Gas Leak Detector


Fire and Gas Detection Controllers: Used to power the connected Methane fire and gas detectors and display measured gas concentrations. They can also monitor the limit values, actuate alarm devices, and initiate risk reduction measures. Recommended MSA Safety products: Fire and Gas Detection Controllers


Combining multiple detection methods can provide a more comprehensive and reliable approach to identifying and addressing methane gas leaks promptly. The choice of method often depends on factors such as the size of the area to be monitored, accessibility, and the severity of potential risks. Understanding the unique properties of methane, from its chemical composition to physical characteristics, underscores the explosive dangers associated with gas leaks. By combining rigorous inspection, advanced detection technologies, emergency shutdown systems, and community education, risks can be mitigated, helping to ensure a safer and more secure future for all.
