Preliminary Study on Explosion Control for Gas Leakage in Residential Buildings
Several explosions due to fuel gas leakages were reported in residential buildings in Hong Kong.There is a need to control the possible explosion for protecting firemen while entering the spaces suspected to have gas leakage.An explosion control scheme was proposed earlier to protect the firemen.Appropriate agents will be injected into the room to lower the relative oxygen content of the concentrations of flammable gases to below lower explosive limit in the space to prevent explosion.Further,chemicals with inhibition effects would suppress the combustion reactions as well.This will prevent or delay ignition caused by small sparks produced due to unknown reasons such as opening the door.Before putting the scheme into action,a long-term study on this method for explosion control on liquefied petroleum gas (LPG) and town gas should be carried out. These gases are commonly used as domestic fuels in Hong Kong.The first stage is to review the effects of explosion to the buildings,effects of suppressing agents and the possible resultant pressure.The explosion pressure under different concentrations of the flammable gases was studied by a simple model.All these will be reported in this paper.
