A technique that controls immediate gas explosions by spraying them with large droplets of water is being tested by scientists at the University of Wales, United Kingdom．Instead of using the traditional fine water sprays when a gas leak is detected, the researchers have discovered that large droplets help to draw in some of the force of any explosion and provide a better way of controlling fire．

The research is based on studies made of the Piper Alpha oil rig （油井） explosion that occurred in the North Sea nine years ago killing 167 workers．The Welsh team found that by covering the gas-leak area with water droplets, the explosion and its effect can be greatly reduced．

Dr Gerand Thomas, a good lecturer in physics at the university’s Center for Explosion Studies, said that it was impossible to deal with gas explosions in the same way as fires because the whole event may only last a quarter of a second and normal water sprays do not have time to be effective．

Using the droplets of water to hold explosions resulted in the water being turned into a mist that allows some force of the explosion to be reduced．The mist slows down the combustion （燃烧） process and can stop a large amount of the gas igniting （点火,燃烧）, thus greatly reducing damage by limiting pressure development．With such a system, the operator has to decide at what point after a gas leak to activate the sprays．

The Center for Explosion Studies is the first of its kind in the UK and has been purposely-built for the study and implication of industrial explosions on land and sea．Research is developed to the causes of accidental explosions and they might be prevented．Full-sized imitative buildings can be built at the center where explosions and fires are created to test preventative equipment using sensors to monitor their efficiency．

Another area that the Welsh researchers have been looking at is how materials respond to explosions．The center also carries out research requested by individual customers．
