Abstract

Napier, D.H. and Roopchand, D.R., 1986. An approach to hazard analysis of LNG spills. Journal of Occupational Accidents, 7: 251-272.The extensive demand for fuel gas in modern communities has led to the construction of liquefied natural gas (LNG) terminals and peak-shaving facilities; the latter are often in close proximity to urban areas. Such installations carry with them actual and other perceived hazards; the analysis and control of these hazards are important. In this paper a logical approach to hazard analysis is described and details of the features of the analysis are outlined. A commentary on dispersion models leads to recommendations for the choice of a suitable dispersion model. Combustion and explosion are also considered and limiting features of acceptability are discussed. Part of this discussion is comprised of an evaluation of the adequacy of thermal radiation models from pool fires. Three methods for predicting radiant flux densities that would be received at the property line are examined and compared to those deduced from the Canadian Standard Z276 which is similar to the NFPA Standard 59A. The basis for setting acceptable minimum values for thermal radiation for both pilot and spontaneous ignition of cellulosic materials is also discussed.In conclusion, various aspects of hazards arising from LNG are considered and broad guidelines for analysis are set down.
