Is LNG safe?

Natural gas fuelling systems are designed to be as safe as conventional fuel systems.  Both LNG-fuelled vehicles and LNG delivery tanker trucks are designed to the highest standards, and the fuel systems and tanks are subject to rigorous testing.

With proper handling, LNG is safe across the value chain through the use of state-of-the-art technology. Industry experience demonstrates that, when handled to the proper gas standard, LNG does not pose greater risks than other fuels such as LPG, gasoline and diesel that are transported every day.
