The use of component logic models to build system fault logic has been discussed by several authors for chemical and electrical systems (Powers and Thompkins, 1974 Fussell, 197.S and Powers and Lapp, 1976). In addition, generic sabotage fault trees have been used for some time in the analysis of security concerns for nuclear power plants (NUREG /CR-0809, NUREG/CR. 121,...

Snccessful full-scale tests on quenching of deflagrations and detonations using expanded metal cartridge flame arresters were performed to USCG standards on Group C and D gases by Westech Industrial Ltd. (Lapp 1992, Lapp and Vickers 1992). 

At first glance, it would appear that the results hy Lapp and Vickers (1992) do not agree with the findings of Frobese and Forster (1992) since the recommended separation distance of Lapp and Vickers is far in excess of that proposed by Frobese and Forster. 

An additional finding by Lapp and Vickers (1992) is that a change in pipe diameter (as above) has the largest detrimental effect during restricted-end deflagration testing.
