In February of this year, Sandia National Laboratory (SNL) kick-started a $7.9-million test program to evaluate large LNG fires on water. SNL built a two-meter-deep pond 120 meters in diameter, spilled LNG on the pond and ignited it. This produced a LNG pool fire 20-m (66-feet) in diameter. The plan ...

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 ...

Process and portable building siting has attracted further interest following the BP Texas city incident. Because of the proximity of office buildings to chemical processes, it is likely that people inside of a building be subjected to higher risks from process hazards than outdoor personnel.
A facility siting study is used ...

While performing consequence modeling we are often required to evaluate damage to population and property from a fire.
Thermal radiation impact to humans from a fire should be based on the dosage – i.e. the intensity of exposure and the duration of exposure. Furthermore, such an impact from thermal radiation on ...
