The DHS has recently released a document outlining that it is believed that terrorists could use hydrogen peroxide and organic fuel mixtures (HPOMs) in an attack against the United States.
The viability, performance and sensitivity of these explosives vary and are based on a number of factors, including the fuel chosen, the ratio of peroxide (an oxidizer) to fuel and the concentration of peroxide used.
Peroxide can be concentrated from lower percentages (ie. household 2% hydrogen peroxide) through heating and all the above ingredients are available in stores.
The organic fuels used in these mixtures inlude many common products such as acetone, black pepper, cumin, ethanol (grain alcohol), flour, ground coffee, honey, nitromethane, sugar, Colas, etc.HPOMs re extremely sensitive to shock/impact, friction, static spark and heat and in large quantities can self-heat and ignite if in sunlight or a hot room.
HPOMs were used in the July 21st, 2007 bombings in England (pictured above).
