||In response to a major accident involving a string of explosions and resulting fires at a large petroleum products tank farm in the United Kingdom in December 2005, several recommendations were made to improve safety in the design and operation of fuel storage sites. Two of these recommendations were that loss of primary containment (tank overfill) should be prevented by a high integrity system, and that industry should agree to undertake a systematic assessment of safety integrity levels using commonly agreed methods. It was also recommended that prior to installing protective systems, one should determine the appropriate level of integrity that such systems are expected to achieve, by means of a "layer of protection analysis" (LOPA). This study aimed to identify common trends and instances of good practices, as well as areas requiring improvement, in the way in which LOPA studies are carried out by operators of sites that store liquid petroleum products in bulk.
