49 C.F.R. § 193.2057 Thermal radiation protection.
Title 49 - Transportation
Each LNG container and LNG transfer system must have a thermal exclusion zone in accordance with section 2.2.3.2 of NFPA 59A (incorporated by reference, see §193.2013) with the following exceptions: (a) The thermal radiation distances shall be calculated using Gas Research Institute's (GRI) report GRI–89/0176 (incorporated by reference, see §193.2013), which is also available as the “LNGFIRE III” computer model produced by GRI. The use of other alternate models which take into account the same physical factors and have been validated by experimental test data shall be permitted subject to the Administrator's approval. (b) In calculating exclusion distances, the wind speed producing the maximum exclusion distances shall be used except for wind speeds that occur less than 5 percent of the time based on recorded data for the area. (c) In calculating exclusion distances, the ambient temperature and relative humidity that produce the maximum exclusion distances shall be used except for values that occur less than five percent of the time based on recorded data for the area.
