An anti-explosion device is explained which prevents any tank containing combustible fluid from exploding from impact or fire. The scientific principles on which Explosafe is based offer an opportunity to erase that danger of fire and explosion in those areas of daily personal and industrial life where man has some control. Fire always will be a hazard as a result of circumstances which man cannot control, such as lightning; but where man can choose what he works with, Explosafe holds out the possibility of improving safety, of reducing loss of life, of saving immeasurable amounts of money now going up in smoke in the damages caused by sudden explosions of flammable liquids and gases.
