As a result of enemy chemical weapons can create a complex chemical environment with the formation of large areas of zones of chemical contamination of the lesions and chemical lesions.Territory, within which the result of the impact of chemical weapons the enemy might defeat personnel, the contamination, equipment and weapons, is called the zone of chemical contamination. The chemical contamination area includes territory, exposed to direct effects of chemical weapons of the enemy (the area of application), and territory, over which spread a cloud of infected air (SV) with striking concentrations.

Area of chemical contamination is characterized by the size (length L and depth G) and the area S₃.

The size of the zone of chemical contamination depend on the amount of applied S, their type, the type and quantity of means of delivery, weather conditions, elevation and topography.

Length:chemical contamination L is determined by the length of the area of the use of chemical weapons (for example, the length of the path of the aircraft, which was pouring from S VAP).

The depth of the zonechemical contamination of G is determined by the depth distribution of the cloud of air, infected S in dangerous concentrations. This is the distance from the upwind boundary of the area of the use of chemical weapons before the turn, stay where people without PPE can lead to initial signs of.

G – depth of area of chemical contamination

L – length of the zone of chemical contamination

– a pointer to the direction and speed of surface wind

2 – surface wind speeds (m/s).

4 – cloudiness in points.

315º – the surface wind direction in degrees from North clockwise to the direction where the wind blows (the azimuth angle).

α – the dispersion of the cloud of contaminated air in the direction perpendicular to the wind direction.

Value α depends on the degree of vertical stability of air:

- in the inversion α = 0.05 G

- when convection α = 0.1 Grams

- when isothermal α = 0.08 G

1 – the area of application S.

2 – territory, on which spread a cloud of infected air-borne concentrations of S.

3 – Lee (far) the boundary of the zone of chemical contamination.

4 windward border of the zone of chemical contamination.

5 – lateral border of the zone of chemical contamination.

S₁; S₂ – foci of chemical destruction.

The hearth of chemical defeatcalled the territory, within which as a result of exposure to chemical weapons of the enemy there was a mass of contamination, infection of weapons and military equipment. The hearth of chemical defeat is characterized by boundaries and area of. In the area of chemical contamination can be one or several lesions, chemical lesions.
