Selected Aspects of Barrier Materials Assessment as a Part of the Reaction on Threats and Risks Connected with CBRN Problems

Observation of Drench of Porous Barrier Materials with Employment of the Conductivity Sensor

“…This methodology allows the visual observation of the liquid phase penetration of the colored test chemicals by 20 exposed sample of the tested material simultaneously with the MINITEST device ( Figure 1). Textile materials from which permeable protective clothing is made are usually combined with hydrophobic and oleophobic treatments and should protect soldiers and firefighters not only against vapors and aerosols of volatile toxic substances but to some extent also against rain and penetration of small drops of CWA (to 20 μl) [24][25][26]. The effectiveness of this protection is based on the PROMOKAVOST methodology for free-flowing drops of water, CWA or model test substances (test chemicals) with a similar surface tension ( Table 1, Figure 1 a, b).…”

Smoothing Methods for Continuous Permeation Data Measured Discretely Designated for Quick Evaluation of Barrier Materials

“…The long-term protection against the permeation of toxic substances is thus determined by the concentration of the toxic substance and the type of used barrier material. Due to the different chemical and physical-chemical characteristics of CWA and TIC, it is currently not possible to find such a breathable or insulating barrier material that meets high chemical resistance requirements while meeting other requirements associated with the long-term activity of military forces in the contaminated area [1][2][3][4][5]. It will always be a compromise between the provided level of protection and the ability to perform an operational task [6][7][8].…”

Full Face Masks Construction and Main Modernization Trends

“…It has to be objectively acknowledged that design trends are mainly determined by military masks, from which the individual components are progressively applied to civilian masks [1,2]. In order to determine the basic modernization trends of the current time, it is necessary to recall the main design characteristics of the 4 th generation masks [3][4][5][6][7][8]. Nowadays, brand new masks should maximally use new technological approaches and must be ready to react on new security threads and be suitable for fulfilment tasks in all kinds of military operations [9][10][11][12][13][14].…”
