PROPELLANTS

At the present time in connection with the widespread introduction in the RUSSIAN armed forces, missile and other technologies have dramatically increased in many chemical products/rocket fuel components, technical fluids/, having marked toxic effects.

The defeat of rocket fuel components/KRT/possible non-compliance with the safety, as well as in emergency situations, that in time of war could lead to a massive military defeat Tal.

The mass flow of the affected this profile, pattern and variety exemplified, the severity and complexity of the pathology, a high percentage of those in need in carrying out urgent actions, great importance will be correct in choosing the tactics of the order and the amount of medical care.

General characteristics of rocket fuel components

Rocket fuels are called substances, able during chemical transformations/burning/emit significant amounts of heat and used as energy sources in aviation, missile technology and other areas of energy. Missile/rocket/propellant is divided into two main categories-solid and liquid. Depending on this distinguished and two types of rocket engines-engines of solid fuel/SOLID/liquid and LIQUID/engines/. The latter are currently the most widespread and used to run intercontinental and space rockets.

According to the method of use of all fuels, used in liquid rocket engines, share on one component and two-component. The ROCKET almost exclusively apply the latest. Unitary fuel serve primarily for activating fuel pumping units and some small engines such as those of rod, for spacecraft orientation/.

The composition of two-component fuel included: fuel /15-25%/ and oxidizer /75-85%/, stored in the engine in different tanks. From here they are fed into the combustion chamber, where chemical products co of substance, flowing from the nozzles, creates a Jet thrust motor.

As oxidants can be applied: liquid oxygen, nitrogen, concentrated hydrogen peroxide, concentrated nitric acid, četyrehokis′ nitrogen, liquid fluoride and other.

The number of chemical compounds, suitable for use as

combustible, is infinitely great. Most recently applied e.g. alcohols/ethanol, propyl, methyl/, some hydrocarbons e.g., Special grades of kerosene/, ammonia, several Aliphatic amines, etc., giving great energy combustion.

Modern rocket propellants, having pronounced okislitel′ny MI and restorative properties, are the most toxic compounds. In some cases, their toxicity is even higher, than, for example, hydrocyanic acid or phosgene, well-known representatives of warfare. This property greatly complicates the work of Jet fuels and sometimes causes a restriction in their application.

Defeat rocket fuels, as a rule, arise in emergency situations and in violation of safety regulations. In wartime, when the destruction of warehouses and stores they, as mentioned above can cause mass poisoning.

The body components of rocket propellants may come by any means: inhalation, through skin, the ingestion. Exposure conditions largely determine the nature and severity of the lesion.

Distinguish: local action, caused by irritating and prižigaûŝim properties of data connections; total action, most often associated with resorption poison with surface light, skin, from the gastrointestinal tract — depending on the ways earnings agent: combined action, combining the first and second character, different especially adverse current in force the so-called syndrome mutual weights. Distinguish between acute and chronic forms lesions.
