LNG import terminals in the U.S. follow NFPA-59A and 49CFR193 standards for facility siting. As a part of the siting studies, LNG regasification facilities report thermal radiation exclusion zones and flammable vapor exclusion zones:
- Flammable vapor hazard zones are based on a design spill from a single accidental source, usually a guillotine rupture.
- Thermal radiation hazards are based on tank fire.
