Enhancing LNG Safety: Advanced Gas and Fire Detection Technologies

Published by , Digital Content Coordinator
LNG Industry,


LNG plays a crucial role in the transition to cleaner energy, but it comes with significant safety challenges. Ensuring the safe handling of LNG, especially in public or industrial areas, requires advanced detection systems to mitigate hazards like gas leaks, fires, and explosions.

Key LNG safety standards

LNG facilities must comply with various international safety standards. These include:

  • ISO 16924: Mandates leak detection systems at LNG fueling stations.
  • EN 13645: Requires fixed detection systems for onshore LNG installations.
  • IEC 60079: Covers gas detectors’ performance in explosive atmospheres.
  • NFPA 72: Guidelines for fire detection systems in hazardous areas.

Meeting these standards is crucial, but advanced detection technology can go beyond compliance to enhance safety.

The need for multi-layered detection

A single detection system may not be able to handle all potential hazards in LNG facilities. Implementing a multi-layered approach that includes various detection technologies can provide broader coverage and reduce the risk of undetected hazards.

Modern systems use a combination of point gas detectors, open-path detectors, ultrasonic monitors, and flame detectors. These technologies work together to maximise detection efficiency and minimise risks.

For example, MSA Safety’s Senscient ELDSTM Open Path Gas (Enhanced Laser Diode Spectroscopy) detectors offer precise gas detection using laser technology. ELDS detectors identify the specific harmonic fingerprint of gases like methane, enabling accurate detection with fewer false alarms. These detectors perform reliably in adverse weather, such as fog or heavy rain, making them ideal for outdoor LNG environments.

The benefits of ELDS technology

ELDS open-path detectors are particularly useful for large areas where point gas detectors may not provide sufficient coverage. The laser technology in these detectors allows for precise gas recognition and reduces the frequency of false alarms – an issue that can lead to costly downtime and erode trust in safety systems.

Another advantage of ELDS is its automated self-check system, which eliminates the need for frequent manual calibrations. This reduces maintenance costs and ensures continuous operation, further improving the safety and efficiency of LNG facilities.

Why detection diversity matters

Using multiple detection methods creates redundancy, improving overall safety. Open-path detectors are ideal for monitoring large areas, while point detectors can cover smaller specific locations . Flame detectors provide protection by detecting fires in high-risk areas and enabling rapid response.

Combining these systems helps LNG operators safeguard against a wide range of potential hazards, ensuring compliance with international standards and maintaining a safe environment for workers and the public.
