The Order of Sensitivity for Highly Sensitive Substances

The commercial products, sporting paper caps (SPC potassium chlorate, red phosphorus and sulfur), toy paper caps (same components as SPC) and silver azide cartridges for breaking renal calculi have lower sensitivity than their powdery components because they are packaged as cartridges. 

Also packaged SPC only bum and do not detonate when they are on fire. Safely packaged SPC are separated by buffering materials between the SPC boxes so that fire will not propagate from one to the other once initiated. As these examples illustrate, there are many ways to make explosives safer by segregating small portions by effective packaging.
