Decontamination of Hydrochloric and Nitric Acids

One of the missions of the Bulgarian Army is the formation of maintenance modules that can take part in a series of military activities, including the eradication of the consequences of natural disasters, chemical and radiological accidents and ecological catastrophes. One task of the module formations in chemical and radioactive incidents is decontamination of equipment, materials and people. Pollution with toxic substances can occur in the area of military operations, tank spills, and terrorist attacks in peacetime. The Hazard Index ranks TIMs according to the chemical's production, transport, storage, toxicity, and vapor pressure. Mineral acids considered „high hazards" are also having a high level of toxicity and vaporize easily. This paper provides some chemical tasks about acids decontamination on non-porous materials. We have investigated the decontamination of hydrochloric and nitric acid in the non-porous surfaces through calculations and their decontamination on wood and concrete surfaces
