Thermal radiation refers to the radiation emanating from a fire burning above a liquefied natural gas (LNG) spill. Thermal radiation from on-site fires fed by an evaporating pool of spilled LNG can cause first, second and third degree burns. The CSAT Top-Screen Survey Application User Guide references U.S. Department of Transportation regulations 49 C.F.R. § 193.2057 (2010) and 49 C.F.R. § 193.2059 (2004), which provide modeling and parameters information for a thermal radiation zone, available at:
