Degassing

Degassing is a complex of measures aimed at decontamination (removal) of toxic substances in various environmental objects. Depending on the method of conducting degassing can be partial and full. Partial degassing is to decontamination (removal) of toxic substances only on those sections of the objects with which a person comes in contact in the course of work. Full decontamination is carried out after running troops, units of the civil defense combat tasks and provides full neutralization S on the treated objects, which exclude the possibility of subsequent defeat of the personnel. Small objects, personal weapons in all cases be subject to full degassing.
Degassing is subjected to all objects contaminated by persistent toxic substances (V-gases S type soman, mustard gas) in droplet liquid or aerosol state. Contamination of weapons, equipment, location in the summer lasts for several days, in winter up to several weeks, months. Persistence of infection depends on the type of toxic substances, the density of contamination, meteorological conditions and the depth of penetration of toxic substances in a variety of materials. While infecting pairs of organophosphorous chemical agents (sarin, soman, V-gases) uniforms, tents and other porous materials, they are also subject degassing.
For degassing of weapons and equipment, medical equipment used degassing substances, solvents and detergents.
The technical means for degassing of weapons and equipment used water dispensing station (ARS), various special decontamination kits and devices; processing machines and vehicles now is hot gas jets. As decontaminating agent use chemically active substances quickly enter into a chemical reaction with poisonous substances, forming toxic compounds (hexachlorane, dichloramine, caustic soda, ammonia water, decreti-main salt hypochlorite calcium- TPA Ledger, bleach). Most often degassing substances used in the form of the following solutions.
Decontamination solution L° 1 - 5% solution of hexachloroethane or 10% solution of dichloramine in dichloroethane. Intended for degassing V-gases, S-type mustard gas. Solution number 1 prepared just before use. Decontamination solution № 2-ad (ammonium alkali) aqueous solution 2% sodium hydroxide, 5% of monoethanolamine and 20% of ammonia. Intended for degassing of toxic substances type soman. Water suspension or water gruel TPA Ledger, water pulp bleach are used for degassing of weapons and equipment contaminated V-gas and mustard gas. However, they cause corrosion of metal surfaces, and therefore degassed their items should rinse with water, wipe dry and lubricated the appropriate lubricant.
Degassing of weapons, equipment, medical equipment is performed by wiping infected surfaces degassing solution.
In the absence of degassing solutions for processing, you can use water solutions detergents and solvents (dichloroethane, gasoline, kerosene and other). In cases when type S is unknown, your weapons, vehicles, medical equipment, Tegaserod solution № 1, then the solution № 2-as.
Degassing objects health property, uniforms, equipment, footwear and personal protective equipment is one of the following ways: 1) by boiling, 2) steam-air-ammonia mixture, 3) paroammachnoj mixture 4) washing, 5) ventilation. Degassing boiling based on the ability S to decompose when exposed to water and high temperatures. To compensate acid products degassing prepare 2-4% a solution of soda. This method is used for the decontamination of metal medical instruments, cotton fabrics, rubber and rubberized fabric. After treatment the items should be dried and aired.
Degassing steam - air - ammonium mixture is carried out on special autodigitizing stations and steam-ammonia mixture - in Budilnik installations. When exposed to hot air (pair) with the decomposition of ammonia S with the formation of toxic products. Degassing steam-air-ammonium mixture can be subjected to all kinds of clothing and equipment; steam-ammonium mixture cannot degassing of fur and leather products.
In the degassing washing with the use of detergents and high temperature hydrolysis (decomposition) S. In this way Tegaserod articles of cotton fabrics and cotton outfit.
While infecting uniforms pairs (but not drops) agents use degassing-aeration. In the summer, when the temperature of 15-20 degree degassing-aeration lasts about 3 hours, in winter time - 6-8 hour. This method is based on the destruction of S in natural conditions under the influence of temperature, moisture and other environmental factors. Applied in case of open, well ventilated areas at a considerable distance from inhabited places.
When degassing wood, rubber, leather goods, as well as tarpaulin, tents and rubber items, covered with paint, note that S is rapidly absorbed these materials, so decontamination should be carried out during the first hours after infection; propagazione objects for some time can be dangerous, they must be ventilated to remove vapours S.
Reliability degassing objects health property, uniforms, equipment, footwear and individual protection means of the above methods is provided only with strict adherence degassing.
Decontamination area is water suspensions TPA Ledger and chlorine with the use of water dispensing stations (ARS), and at their absence degassing solutions # 1 and # 2.
On a separate areas contaminated soil can be removed mechanically.
In case of infection poisonous substances food degassing is to remove the infected surface layer and thorough cooking. Products typically used without cooking, destroy. The decision on the suitability of products for use only accepted after carrying out special studies on S in laboratories.
Decontamination of contaminated water is filtered through special filters, distillation and brewing. The most reliable way is water disinfection with the use of filters, sorbing S.
Degassing of water can be conducted using the equipment of water supply stations, autofallthrough stations (IT), multi-functional handheld filter (UNF), the tissue-carbon filter (TUFF) and other technical means.
Distillation and boiling are used for degassing of small quantities of water.
