LNG - Fires & Explosions


If LNG is spilled, it vaporizes. The natural gas vapors are initially heavier than air and they form a cloud close to the ground, which is pushed downwind and eventually dissipates. If a viable ignition source is present where a vapor cloud exists at a 5%–15% concentration in air, the vapor cloud can ignite and burn. Exponent’s scientists and engineers have significant experience in the investigation, analysis, and prevention of fires and explosions, and we use this experience to assist clients in both a reactive investigation mode in working to prevent such incidents from happening.
