A smoke screen that is particularly suitable for exercises is to be produced by the present invention, said smoke screen being in the form of an aerosol that is neither toxic to humans and animals in its effect, nor hazardous to the environment. This is achieved with a so-called pyrotechnic set that is made up as follows, A light-metal powder, preferably magnesium powder (Mg) as a metallic reducing agent, potassium nitrate (KNO3) or a mixture of potassium nitrate (KNO3) and potassium perchlorate (KClO4) as the main oxidizing agent, at least one carbonate, e.g., calcium carbonate (CaCO3), potassium hydrocarbonate (KHCO3), sodium hydrocarbonate (NaHCO3), potassium carbonate (K2CO3), sodium carbonate (Na2CO3), and substances that give off nitrogen as combustion moderators, as well as at least one additional substance that can be sublimated or vapourized, forms smoke, and is non-toxic. |
