Adequate and timely protection of the people and the infrastructure necessary increase efficiency in liquidation of the consequences of chemical, radiological and biological agents. CBRN decontamination teams are using decontamination technique to minimize exposure to hazardous agents and limit the spread of contamination. The disposables decontamination means and methods are very divers, and an evaluation of the most appropriate aspects often encountered in the real cases could determine the adequate organization approach to be used.

The object of the paper is the solid water. The water is a model pollution with calcium dichloride. We used complexonometric method to determine the hardness. We have analysed the amount of softener influencing the hardness of the water, which is used to decontaminate humans.

Calcium hydroxide is an inorganic compound used for many purposes. Calcium hydroxide is relatively soluble in water. It partially dissolves in water to produce a solution called limewater, which is a moderate base. Limewater or aq. Ca(OH)2 reacts with acids to form salts. As the calcium hydroxide is easy accessible, cheap and has the possibility to neutralize inorganic acids can be successfully used in their decontamination. This paper presents analyzes the decontaminating properties of calcium hydroxide.

In this work a new device for measuring the parameters of a fog is described. It is developed by our team and is called Fog Detector Indicator 1 (FDI-1). It is a part of a sensor system for control of the parameters of a fog which is used for decontamination of objects polluted by different circumstances. FDI-1 is a custom indication unit used in various systems for evaluation of fog parameters that gives the operator a visual result for the change of the input voltage. The main function of the indicator is to show the measured voltage applied on its coax input. Usually, this measurement can be done with a regular voltmeter, but the nature of the measurement of a fluid (fog) density, droplet diameter or contamination assumes very rapid changes of the measured values and also very short peaks of the maximum and the minimum of the measured variable. FDI-1 is can be used namely in such cases.
