LNG Safety

In its liquid state, LNG is not explosive and cannot burn. For LNG to burn, it must first vapourise and mix with air in the proper proportions, between 5% to 15%, and then be exposed to an ignition source. In the event of a leak, LNG vapourises rapidly, turning into a gas and mixing with air. If this mixture is within the flammable range, there is a risk of ignition. In addition, LNG, or any vapour associated with LNG, will not explode in an unconfined environment. Thus, in the unlikely event of an LNG spill, the natural gas has little chance of igniting an explosion.

LNG safety requirements, along with the industry standards and best practices, are designed to ensure the safety and security of all LNG facilities. LNG storage tanks and other equipment are made of suitable materials with the proper design engineering. There are also safeguard systems, such as gas, liquid and fire detectors to identify any failures as well as remote and automatic shut-off systems to minimize leaks and spills.
