@X087@X05.@X081 @X03 SMOKE BOMBS
@X08One type of pyrotechnic device that might be employed by a terrorist in
many way would be a smoke bomb@X05.@X08 Such a device could conceal the getaway route@X05,
@X08or cause a diversion, or simply provide cover@X05.@X08 Such a device, were it to
produce enough smoke that smelled bad enough@X05,@X08 could force the evacuation of a
building@X05,@X08 for example@X05.@X08 Smoke bombs are not difficult to make@X05. @X08Although the
military smoke bombs employ powdered white phosphorus or titanium compounds@X05,
@X08such materials are usually unavailable to even the most well@X05-@X08equipped terrorist@X05.@X08
Instead@X05,@X08 he@X05/@X08she would have to make the smoke bomb for themselves@X05.@X08
Most homemade smoke bombs usually employ some type of base powder@X05,@X08 such
as black powder or pyrodex@X05,@X08 to support combustion@X05.@X08 The base material will burn
well@X05,@X08 and provide heat to cause the other materials in the device to burn@X05,@X08 but
not completely or cleanly@X05.@X08 Table sugar@X05,@X08 mixed with sulfur and a base material@X05,@X08
produces large amounts of smoke@X05.@X08 Sawdust@X05,@X08 especially if it has a small amount
of oil in it@X05,@X08 and a base powder works well also@X05.@X08 Other excellent smoke
ingredients are small pieces of rubber, finely ground plastics, and many
chemical mixtures@X05.@X08 The material in road flares can be mixed with sugar and
sulfur and a base powder produces much smoke@X05.@X08 Most of the fuel@X05-@X08oxodizer
mixtures@X05,@X08 if the ratio is not correct@X05,@X08 produce much smoke when added to a base
powder@X05.@X08 The list of possibilities goes on and on@X05.@X08 The trick to a successful
smoke bomb also lies in the container used@X05.@X08 A plastic cylinder works well@X05,@X08 and
contributes to the smoke produced@X05.@X08 The hole in the smoke bomb where the fuse
enters must be large enough to allow the material to burn without causing an
explosion@X05.@X08 This is another plus for plastic containers@X05,@X08 since they will melt
and burn when the smoke material ignites@X05,@X08 producing an opening large enough to
prevent an explosion@X05.@X08
